Corporation (“Pegatron”), and Wistron Corporation (“Wistron”) and will be collectively referred to as
the “Contract Manufacturers” or “CM’s.” As Apple and the CMs have brought the same arguments, the
Court will refer to Apple and the CMs claims in shorthand as “Apple’s” Claims.

This Court previously dismissed nine “Additional Patents-in-Suit” added by Apple and the CMs in the
First Amended Complaint and the Contract Manufacturers’ Counterclaims for a lack of declaratory
judgment jurisdiction. Dkt. No. 167. The Court granted leave to amend, but the parties did not file any

The Court held a technology tutorial on March 8, 2018. Dkt. No. 361. The Court
8
will hold a claim construction hearing on March 22, 2018 at 9 AM. The parties will be
9
given the opportunity to address the tentative ruling at the scheduled hearing. The Court
10
has reviewed the claims, specifications, and other relevant evidence, and has considered
11
the briefing and arguments of the parties and provides this tentative decision: (1)
12
construing disputed terms of six of the nine patents-in-suit and (2) denying Qualcomm’s

2008). “It is a bedrock principle of patent law that the claims of a patent define the
2
invention to which the patentee is entitled the right to exclude.” Phillips v. AWH Corp.,
3
415 F.3d 1303, 1312 (Fed. Cir. 2005) (en banc) (internal marks omitted). As such,
4
claims are to be construed in a manner that “stays true to the claim language and most
5
naturally aligns with the patent’s description of the invention.” Id. at 1316.
6
To construe disputed terms, the court first looks to the claims themselves. See
7
Innova/Pure Water, Inc. v. Safari Water Filtration Sys., Inc., 381 F.3d 1111, 1116 (Fed.
8
Cir. 2004). Generally, claim language is given its “ordinary and customary meaning,”
9
which is “the meaning that the term would have to a person of ordinary skill in the art in
10
question at the time of the invention.” Phillips, 415 F.3d at 1312-13. In cases where the
11
“ordinary and customary meaning” is clear, claim construction involves “little more than
12
the application of the widely accepted meaning of commonly understood words.” Id. at
13
1314. In cases where it is not immediately apparent what a person of ordinary skill in the
14
art would understand a claim to mean, the court looks to other sources to decipher the
15
correct meaning. Id. at 1314. Those sources include intrinsic and extrinsic evidence
16
“available to the public that show what a person of skill in the art would have understood
17
disputed claim language to mean.” Id. “Importantly, the person of ordinary skill in the
18
art is deemed to read the claim term not only in the context of the particular claim in
19
which the disputed term appears, but in the context of the entire patent, including the
20
specification.” Id. at 1313.
21
When such clarity is required, a court begins by examining the intrinsic record,
22
consisting of the language of the claims, the patent specification and, if in evidence, the
23
prosecution history of the challenged patent. Id. at 1314; see also Vederi, LLC v. Google,
24
Inc., 744 F.3d 1376, 1382 (Fed. Cir. 2014). “The appropriate starting point . . . is always
25
with the language of the asserted claim itself.” Comark Comms., Inc. v. Harris Corp.,
26
156 F.3d 1182, 1186 (Fed. Cir. 1998). The context in which a disputed term appears
27
often provides substantial guidance as to the meaning of the term. See Philips, 415 F.3d
28
3
17-cv-00108-GPC-MDD
1
at 1313-14. A disputed term should be construed “consistently with its appearance in
2
other places in the same claim or in other claims of the same patent.” Rexnord Corp. v.
3
Latiram Corp., 274 F.3d 1336, 1342 (Fed. Cir. 2001). “A claim construction that gives
4
meaning to all the terms of the claim is preferred over one that does not do so.” Vederi,
5
744 F.3d at 1383.
6
As for other intrinsic evidence, the specification “is always highly relevant to the
7
claim construction analysis” and “usually dispositive.” Philips, 415 F.3d at 1315. In
8
fact, it has been observed that “[a]part from the claim language itself, the specification is
9
the single best guide to the meaning of a claim term.” Vederi, 744 F.3d at 1382; see also
10
Philips, 415 F.3d at 1315. “[A] claim construction that excludes [a] preferred
11
embodiment [described in the specification] is rarely, if ever, correct and would require
12
highly persuasive evidentiary support.” Adams Respiratory Therapeutics, Inc. v. Perrigo
13
Co., 616 F.3d 1283, 1290 (Fed. Cir. 2010) (internal marks omitted). Furthermore, the
14
“written description part of the specification” should not be read to “delimit the right to
15
exclude [as] [t]hat is the function and purpose of claims.” Markman, 52 F.3d at 980.
16
Stated differently, a “claim construction must not import limitations from the
17
specification into the claims.” Douglas Dynamics, LLC v. Buyers Prods. Co., 717 F.3d
18
1336, 1342 (Fed. Cir. 2013). It is, therefore, “improper to read limitations from a
19
preferred embodiment described in the specification—even if it is the only
20
embodiment—into the claims absent a clear indication in the intrinsic record that the
21
patentee intended the claims to be so limited.” Dealertrack, Inc. v. Huber, 674 F.3d
22
1315, 1327 (Fed. Cir. 2012) (citations omitted).
23
“A patentee is,” however, “free to be his own lexicographer.” Markman, 52 F.3d
24
at 980. Where the inventor gives a term a special meaning, “the inventor’s lexicography
25
governs.” Philips, 415 F.3d at 1316. Similarly, where the inventor specifically disclaims
26
a certain scope in the specification, that disclaimer is dispositive. Id.
27
28

17-cv-00108-GPC-MDD
1
In most situations, “an analysis of the intrinsic evidence alone will resolve any
2
ambiguity in a disputed claim term.” Vitrionics Corp. v. Conceptronic, Inc., 90 F.3d
3
1576, 1583 (Fed. Cir. 1996). Where that is the case, “it is improper to rely on the
4
extrinsic evidence” as “[t]he claims, specification, and file history, rather than extrinsic
5
evidence, constitute the public record of the patentee’s claim, a record on which the
6
public is entitled to rely.” Id. However, to the extent “the intrinsic record is ambiguous,
7
and when necessary,” a court “may rely on extrinsic evidence, which consists of all
8
evidence external to the patent and prosecution history, including expert and inventor
9
testimony, dictionaries and learned treatises.” Power Integrations, Inc. v. Fairchild
10
Semiconductor Int’l, Inc., 711 F.3d 1348, 1360 (Fed. Cir. 2013). Extrinsic evidence,
11
however, is “less significant than the intrinsic record” and “less reliable than the patent
12
and its prosecution history in determining how to read claim terms.” Phillips, 415 F.3d at
13
1317-18 (internal quotations and citation omitted).
14
Finally, “terms do not need to be construed [where] they are neither unfamiliar to
15
the jury, confusing to the jury, nor affected by the specification or prosecution history.”

See Bd. of Trustees of Leland Stanford Junior Univ. v. Roche Molecular Sys., Inc., 528 F.
17
Supp. 2d 967, 976 (N.D. Cal. 2007) (citing United States Surgical Corp. v. Ethicon, Inc.,
18
103 F.3d 1554, 1568 (Fed. Cir. 1997) (“Claim construction is a matter of resolution of
19
disputed meanings and technical scope, to clarify and when necessary to explain what the
20
patentee covered by the claims, for use in the determination of infringement. It is not an
21
obligatory exercise in redundancy.”)). A determination that a claim term “needs no
22
construction” or has the “plain and ordinary meaning” may be inadequate when a term
23
has more than one “ordinary” meaning or when reliance on a term’s ordinary meaning
24
does not resolve the parties’ dispute. EON Corp. v. Silver Spring Networks, 815 F.3d
25
1314, 1318 (Fed. Cir. 2016). Where the parties dispute the scope of a claim term, it is the
26

35 U.S.C. § 112(f) provides a set of special rules for construing means-plus-
3
Means-Plus-Function Claims
function claims. 5 The statute states:
4
An element in a claim for a combination may be expressed as a means or step
5
for performing a specified function without the recital of structure, material,
6
or acts in support thereof, and such claim shall be construed to cover the
7
corresponding structure, material, or acts described in the specification and
8
equivalents thereof.
9
35 U.S.C. § 112(f). Accordingly, Section 112(f) allows a patentee to express an element
10
of a claim as a means for performing a specified function. In exchange the convenience of
11
making a functional claim, the patent seeker must pay a price in that the “patent
12
specification must disclose with sufficient particularity the corresponding structure for
13
performing the claimed function and clearly link that structure to the function.” Triton
14
Tech of Texas, LLC v. Nintendo of Am., Inc., 753 F.3d 1375, 1378 (Fed. Cir. 2014).
15
Construing a means-plus-function claim term is a two-step process. The court must
16
first identify the claimed function. Noah Sys., Inc. v. Intuit Inc., 675 F.3d 1302, 1311
17
(Fed. Cir. 2012). Then, the court must determine what structure, if any, disclosed in the
18
specification corresponds to the claimed function. Where there are multiple claimed
19
functions, the patentee must disclose adequate corresponding structure to perform all of
20
the claimed functions. Id. at 1318–19. If the patentee fails to disclose adequate
21
corresponding structure, the claim is indefinite. Id. at 1311–12.
22
Structure disclosed in the specification qualifies as “corresponding structure” if the
23
intrinsic evidence clearly links or associates that structure to the function recited in the
24
claim. Id. (citing B. Braun Med., Inc. v. Abbott Labs., 124 F.3d 1419, 1424 (Fed. Cir.
25
1997)). Even if the specification discloses corresponding structure, the disclosure must be

The statute was previously referred to as 35 U.S.C. § 112 ¶ 6, but was codified as 112(f) in the
America Invents Act of 2012.

of “adequate” corresponding structure to achieve the claimed function. Id. at 1311–12
2
(citing In re Donaldson Co., 16 F.3d 1189, 1195 (Fed. Cir. 1994) (en banc)). Therefore, if
3
a person of ordinary skill in the art would be unable to recognize the structure in the
4
specification and associate it with the corresponding function in the claim, a means-plus-
5
function clause is indefinite. Id. at 1312 (citing AllVoice Computing PLC v. Nuance
6
Commc'ns, Inc., 504 F.3d 1236, 1241 (Fed. Cir. 2007)).
7
If the function is performed by a general purpose computer or microprocessor, then
8
the specification must also disclose the algorithm that the computer performs to
9
accomplish that function. Nintendo, 753 F.3d at 1378 (citing Aristocrat Technologies v.
10
International Game Technology, 521 F.3d 1328, 1333 (Fed. Cir. 2008). Failure to
11
disclose the corresponding algorithm for a computer-implemented means-plus-function
12
term renders the claim indefinite. Id. (citing Ergo Licensing LLC v. Carefusion 303, Inc.,
13
673 F.3d 1361, 1363 (Fed. Cir. 2012)).
14
It is well settled that “[s]imply disclosing software, however, ‘without providing
15
some detail about the means to accomplish the function[,] is not enough.’” Function
16
Media, L.L.C. v. Google, Inc., 708 F.3d 1310, 1318 (Fed. Cir. 2013) (citing Noah Sys.,
17
Inc. v. Intuit, Inc., 675 F.3d 1302, 1312 (Fed. Cir. 2012)). When dealing with a “special
18
purpose computer-implemented means-plus-function limitation,” the Federal Circuit
19
requires the disclosure of the algorithm for performing a function. Noah Sys., 675 F.3d at
20
1312. The Federal Circuit requires that the structure disclosed in the specification, in this
21
scenario, to be “more than simply a general purpose computer or microprocessor.” Id.
22
The “specification can express the algorithm in any understandable terms including as a
23
mathematical formula, in prose, or as a flow chart, or in any other manner that provides
24
sufficient structure.” Finisar Corp. v. DIRECTV Grp., Inc., 523 F.3d 1323, 1340 (Fed.
25
Cir. 2008) (internal citation omitted). While a patentee need not disclose details of
26
structures well known in the art, the “specification must nonetheless disclose some
27
structure.” Default Proof Credit Card Sys., Inc. v. Home Depot U.S.A., Inc., 412 F.3d
28
7
17-cv-00108-GPC-MDD
1
1291, 1302 (Fed. Cir. 2005). Consequently, the “testimony of one of ordinary skill in the
2
art cannot supplant the total absence of structure from the specification.” Id. Finally, the
3
“party alleging that the specification fails to disclose sufficient corresponding structure
4
must make that showing by clear and convincing evidence.” TecSec, Inc. v. IBM Corp.,
5
731 F.3d 1336, 1349 (Fed. Cir. 2013).

‘021 patent provides a method by which a mobile station performs power measurements
of the second cellular system when the power level of the first cellular system drops below
a certain threshold level. JA7 at 2:52-60. To determine whether it should handover to the
second cellular system, the mobile station requests a “free” time period during which the
mobile station is “free” from the first cellular system’s transmissions. JA8 at 3:5-10.
During the “free” period, the mobile station is able to more accurately measure power from

The parties do not dispute that this term should be construed as a means-plus-

function claim pursuant to 35 U.S.C. § 112(f). Further, they do not dispute that the function
19
is “comparing the measured power level with said at least one threshold value.”
20
Apple argues that Qualcomm has not identified adequate structure in the
21
specification corresponding to the function. Apple asserts that Qualcomm has identified
22
only a “black box” as the specification identifies only a generic control unit or control block
23
for performing this “comparing function.” Qualcomm argues that the ‘021 Patent discloses
24
sufficient structure, arguing that it is a “typical” component in a mobile station.
25
For ease of reference, Figure 6 to the ‘021 patent is reproduced below. Figure 6

5
from the cellular radio system to shift into the compressed transmission mode, in which
6
the mobile station can measure also the transmission powers of a second system.” JA10 at

The Court concludes that the “means for comparing the measured power level with
22
23
24
25
26
27
28

disclose sufficient structure and has disclosed merely a “black box.” See Augme Techs.,

that performs the recited function is not a sufficient explanation of the algorithm required
2
to render the means-plus-function term definite.”). Under federal circuit law, when an
3
inventor invokes means-plus-function claiming in a computer-implemented invention, the
4
disclosed structure must be more than simply a general purpose computer or
5
microprocessor. See Aristocrat Techs, 521 F.3d at 1333. The control block 605 and its
6
comparison means 616 do not constitute sufficient structure because Qualcomm has failed
7
to include a reference to an algorithm. See Noah Sys., 675 F.3d at 1312 (it is well settled
8
that “[s]imply disclosing software, however, without providing some detail about the
9
means to accomplish the function is not enough”) (internal marks omitted). The patent
10
does not contain any understandable terms that could conceivably construed as an
11
algorithm, including inter alia as a mathematical formula, flow chart, or any other manner
12
that provides sufficient structure. Finesar, 523 F.3d at 1340. An inventor who chooses to
13
utilize a means-plus-function formulation must necessarily disclose adequate structure so
14
that the bounds of the invention can be perceived. Id. (“Without any corresponding
15
structure, one of skill simply cannot perceive the bounds of the invention.”). Notably,
16
neither Qualcomm, nor its expert Dr. Min attempts to identify how the ‘021 Patent
17
discloses any algorithm to perform the “comparing” function.
18
Qualcomm attempts to sidestep the Federal Circuit’s requirement for disclosure by
19
pointing to Telcordia Techs. Inc. v. Cisco Sys., Inc., 612 F.3d 1365, 1377 (Fed. Cir. 2010).
20
In Telcordia, the Federal Circuit rejected an indefinite challenge where a controller’s
21
circuit was a “black box” that did not describe the “details of its inner circuitry.” 612 F.3d
22
at 1377. There, the term “monitoring means” was a 112(f) means-plus-function claim
23
where the function was “evaluating the integrity of the multiplexed subrate
24
communications on the first ring and the second ring,” and the corresponding structure for
25
the function was the “circuitry at a controller that determines if a defect exists with the
26
multiplexed subrate communications.”
27
specification need “only disclose adequate defining structure to render the bounds of the
28
11
Id. at 1376.
The Court concluded that the
17-cv-00108-GPC-MDD
1
claim understandable to an ordinary artisan.” Id. Because an ordinary artisan would have
2
recognized the controller as an electronic device with a known structure, there was
3
sufficient structure to render the claim definite. Id. Telcordia is inapposite. The function
4
addressed in Telcordia did not require the use of specific programming through a
5
microprocessor or software sufficient to trigger the Federal Circuit’s requirement to
6
disclose an algorithm.
7
Qualcomm argues that the ‘021 patent does not require the controller to be a
8
“microprocessor or software.” Qualcomm is correct that the specification’s description of
9
comparison means 616 arises in the context of a “preferred embodiment” where it can be
10
realized “for instance with the aid of a microprocessor or software.” Pointing to a series
11
of non-binding district court cases, Qualcomm asserts that in certain situations disclosure
12
of controllers alone have been found by district courts to be sufficiently definite structure.
13
The Court finds these cases distinguishable. For example, Maury Microwave, Inc. v. Focus
14
Microwaves, Inc., 2012 WL 9161988, at *20 (C.D. Cal. July 30, 2012) is inapposite
15
because there the specification did not clearly mandate a computer algorithm to perform
16
the function. Here, the extrinsic evidence, discussed below, shows that an algorithm or
17
additional structure is necessary for control block 605 and comparison means 616 to
18
perform the comparing function. Moreover, unlike in Goss Intern. Americas, Inc. v.
19
Graphic Management Associates, Inc., 739 F. Supp. 2d 1089, 1100 (N.D. Ill. 2010), there
20
is no indication that the 605 control block “consist[s] of only circuitry” that does not “even
21
require any algorithms at all” to perform the requisite function.8 Consequently, these cases
22
are inapposite because the structure disclosed here requires both a control block 605 and a
23
24
25
26
27
28
8
Similarly, the Court does not find Technologies Properties, Ltd. v. Canon, Inc., 2015 WL 5535830, at
*4-6 (N.D. Cal. Sep. 18, 2015) persuasive. There, the Court distinguished Aristocrat because there was
no argument that a microprocessor was not necessary to “accomplish the recited functions,” leading the
Court to find that “[t]he holding from Aristocrat requiring disclosure of an algorithm does not extend to
a function that can be performed by an integrated circuit or chip.” Here, the extrinsic evidence,
uncontested by Qualcomm’s expert Dr. Min, shows that an algorithm would be required to perform the
comparing function.
12
17-cv-00108-GPC-MDD
1
comparison means 616. According to the extrinsic evidence and a reading of a “preferred
2
embodiment,” comparison means 616 would likely require either a microprocessor or
3
software to perform the function.
4
The Court’s conclusion is informed by the extrinsic evidence and particularly credits
5
the Declaration of Apple’s expert Dr. Wicker. Dr. Wicker contends that microprocessors
6
and software are incapable of accomplishing the “comparing” function without specific
7
algorithms. JA314 ¶ 48 (concluding that “control block 605” as described in the ‘021
8
Patent is a “Black Box” that is not a “sufficient explanation of any algorithm.”). 9 Wicker
9
states that “no generic hardware or software by itself can accomplish the different functions
10
of the control unit or control block recited in the patent. In fact, specialized programming
11
and/or additional structural features are required to perform the identified functions.
12
JA314. In its Responsive Claim Construction Brief, Qualcomm contends for the first time
13
that the recited function involves merely comparing two values, which “can be achieved
14
by any general purpose computer without special programming.” QRCB at 3 (citing In re
15
Katz Interactive Call Processing Patent Litig., 639 F.3d 1303, 1316 (Fed. Cir. 2011)).
16
Pertinently, Qualcomm does not present any extrinsic evidence to rebut Dr. Wicker’s
17
claims that a POSITA would understand that the recited function cannot be accomplished
18
by the 605 controller block and comparison means 616 without specific algorithms.
19
Notably, Dr. Min never states that the comparing function can be accomplished without a
20
specific algorithm. The Court will accordingly conclude that Katz is inapposite10 and will
21
accept Dr. Wicker’s contention that the “comparing” function requires the use of
22
23
24
25
26

9
Qualcomm challenges Dr. Wicker’s lack of “supporting citations.” QOCB at 9. In his deposition, Dr.
Wicker explained that this was because he was citing to an absence in a written description and that
these assertions are based on his “experience as a telecom engineer for 30-something years.” QEX17 at
75:1-25; 78:1-7
10
In Katz, the patentee did not claim a specific function performed by a special purpose computer, but
merely recited claimed functions of “processing,” “receiving,” and “storing” that could have been
achieved by any general purpose computer without special programming. See Katz, 639 F.3d at 1313.
Here, Apple’s unrebutted expert testimony is that the comparing function requires specialized
programming. See JA 314.
13
17-cv-00108-GPC-MDD
1
specialized programming, i.e. algorithms.
2
Dr. Min asserts only that control unit/control block 605 is sufficient to perform the
3
claimed function because the structure of mobile station controllers was well known to
4
persons of ordinary skill in the art. JA397 ¶¶ 89-92. Dr. Min cites common block 605-
5
type processors such as GSM & W-CDMA baseband processors and GSM digital base-
6
band chip. 11 Whether the 605 block was a “typical” structure in a mobile device does not
7
automatically lead to the legal determination of adequate structure to support a means-plus-
8
function claim, particularly in light of the Federal Circuit’s case law requiring the
9
disclosure of algorithms for computer-implemented functions. Given the total absence of
10
structure, the Court need not and will not consider Dr. Min’s conclusory statements. See
11
Citrix, 792 F.3d at 1354 (“The testimony of one of ordinary skill in the art cannot supplant
12
the total absence of structure from the specification.”). This is consistent with the rationale
13
of 112(f) claims. Williamson, 792 F.3d at 1354 (“The prohibition against using expert
14
testimony to create structure where none otherwise exists is a direct consequence of the
15
requirement that the specification adequately disclose corresponding structure.”)
16
17
18
Accordingly, the Court concludes that this term is indefinite because the ‘020 patent
fails to disclose adequate structure corresponding to the “comparing” function. See id.

Apple contends that the plain language of the term requires that the function

include the “only after said measured power level remains below said at least one

3
When construing functional claims under § 112(f), “[t]he statute does not permit
4
limitation of a means-plus-function claim by adopting a function different from that
5
explicitly recited in the claim.” In re Teles AG Informationstechnologien, 747 F.3d 1357,
6
1367-68 (Fed. Cir. 2014) (citing Micro Chem., Inc. v. Great Plains Chem. Co., 194 F.3d
7
1250, 1258 (Fed. Cir. 1999) (“[T]he district court erred . . . by incorporating unrecited
8
functional limitations into the claims.”)). An “error in identification of the function can
9
improperly alter the identification of structure in the specification corresponding to that
10
function.” Micro Chem., 194 F.3d at 1258. Notably, “[t]hat part of a claim contains
11
means-plus-function language does not make section 112 ¶ 6 applicable to the entirety of
12
the claim.” Johnston v. IVAC Corp., 885 F.2d 1574, 1580 (Fed. Cir. 1989).
13
The Court concludes that “said means being arranged to transmit the request for
14
the free time period in which to perform the measurement only after said measured power
15
level remains below said at least one threshold value” is a separate claim term that is not
16
a part of the instant means-plus-function term. See Bausch & Lomb Inc. v. Moria S.A.,
17
222 F. Supp. 2d 616, 655-56 (E.D. Pa. 2002) (construing function to be merely “retains
18
and positions the eye on which cutting of the cornea is to be performed” where claim
19
language stated “means for retaining and positioning the eye on which cutting of the
20
cornea is to be performed, said means being capable of temporary attachment to a portion
21
of the eye surrounding the cornea being capable of exposing and presenting the cornea to
22
be cut.”) (emphasis added). The Court agrees with Qualcomm that Apple is attempting to
23
import a separate limitation in an attempt to shoehorn controller block 605 as required
24
structure. In particular, the Court credits Qualcomm’s argument that the “said means
25
being arranged” term is a separate limitation describing when the function occurs, and
26
does not constitute a description of the function itself.
27
28
16
17-cv-00108-GPC-MDD
1
The Court is not persuaded by Apple’s citation to the prosecution history. As
2
originally drafted, the patentee stated “means (617) for requesting a free measurement
3
period from the first cellular radio system, which means are arranged to request the free
4
measurement period when said measured signal strength is lower than said threshold
5
value.” AEX 30 at 101. After a rejection from the PTO, the patentee amended as follows
6
(additions in underline, deletions in strikethrough):
7
• means (617) for transmitting to the first cellular radio system a requesting request
8
for a free time period in which to perform the measurement period from the first
9
cellular radio system, which said means are being arranged to transmit the request
10
for the free time period in which to perform the measurement period when said
11
measured signal strength power level remains lower than below said at least one
12
threshold value [[,]] . . .
13
AEX30 at 109. It is not clear to the Court how the prosecution history “disclaim[s] or
14
“disavow[s]” Qualcomm’s assertion that the transmitting function should not include the
15
second post-comma clause. See Teleflex, Inc. v. Ficosa N. Am. Corp., 299 F.3d 1313,
16
1326 (Fed. Cir. 2002). Even as originally drafted, the original phrasing contained an
17
explicit second clause––“radio system, which means are arranged” that would not have
18
served as a limitation on the means-plus-function claim asserted in the first clause of the
19
claim.
20
Accordingly, the Court concludes that the function for this term is “transmitting to
21
the first cellular radio system a request for a free time period in which to perform the
22
measurement.”
23
24
Structure
Apple argues that “transmitter block 604” cannot send the recited transmissions
25
without “control block 605” which determines when to transmit the request by checking
26
whether the power level remains below a threshold value. Accordingly, Apple contends
27
28
17
17-cv-00108-GPC-MDD
1
that the corresponding structure for “means for transmitting” necessarily includes
2
“control block 605,” which Apple argues is a black box indefinite term.
3
Qualcomm responds that transmitter block 604 is adequate structure as it follows
4
directly from the Patent’s description as performing the recited function. Transmission
5
block 604 “process[es], modulate[s], and amplifie[s]” transmission signals JA10 at 8:2-5.
6
Qualcomm asserts Apple’s construction of function––which includes the limitation “only
7
after said measured power level remains below said at least one threshold value,” leads to
8
the erroneous inference that Control Block 605—not merely transmission block 604––is
9
a necessary part of this term’s structure.
10
Because the Court has construed the function of this term to not require the
11
separate claim limitation “said means being arranged to transmit the request for the free
12
time period in which to perform the measurement only after said measured power level
13
remains below said at least one threshold value,” the Court cannot conclude that control
14
block 605 is a requisite structure for the identified function. Here, control block 605 is
15
not necessary for the function of “transmitting to the first cellular radio system a request
16
for a free time period in which to perform the measurement.” Accordingly, the Court
17
concludes that Qualcomm’s disclosure of transmitter block 604 and equivalents is
18
sufficiently definite structure. See JA397-398 (Declaration of Dr. Min asserting that a
19
POSITA would understand transmitter block 604 to be adequate corresponding structure
20
for the transmitting function).

The parties do not dispute that these terms should be construed as means-plus-

25
dispute whether the structure for each term—which the parties agree involve receiver block
26
611—is limited to the CDMA or TDMA cellular radio systems disclosed in the ‘021 patent
27
at lines 7:57 to 8:45.
28
19
17-cv-00108-GPC-MDD
1
Apple argues that the ‘021 patent discloses both the measuring and receiving
2
functions, but does not provide any detail regarding the structure of receiver block 611 or
3
its implementation. AOCB at 8. According to Apple, the only networks described in the
4
‘021 patent are CDMA or TDMA type systems, and thus the structure must be limited to
5
these networks. Importantly, Apple’s theory would exclude OFDMA systems such as
6
LTE. Id. Apple’s expert Dr. Wicker asserts that specialized programming and additional
7
features would be required to perform LTE functions, which are distinct from those for a
8
UMTS receiver. JA311 ¶ 41.
9
Qualcomm responds that nothing in the plain language of the ‘021 patent limits the
10
611 receiver block to only CDMA or TDMA radio systems. QOCB at 4. Qualcomm
11
asserts that any references to particular cellular systems are qualified by “exemplary
12
description” language. QOCB at 4-6.
13
The Court agrees with Qualcomm. Nothing in the specification indicates that the
14
structure should be restricted to only CDMA or TDMA systems. The ‘021 Patent describes
15
the 611 receiver block without any reference to particular cell systems. See JA10 at 7:63-
16
67. Indeed, the “Background of the Invention” accounts for the development of a new type
17
of cellular system, such as the OFDMA based systems that underlie modern-day LTE
18
networks. See JA7 at 1:25-40 (“New network topologies will rise in parallel with [the
19
GSM] network, and typically the utilization of these new topologies require new terminals.
20
In the future it must be possible to use the terminals in a number of networks. Then a
21
change over from the use of a first network to the use of a second network must be effected
22
without problems.”).
23
systems are qualified by exemplary description language. See, e.g., JA9 at 5:40-46 (“[F]or
24
instance, in a situation where said first network is a WCDMA network and said second
25
network is a GSM 900 network . . . .”). Finally, claims 8-11 indicate specific cellular
26
systems, while claim 12 does not, indicating that the patentee did not intend to so restrict
27
claim 12 to CDMA or TDMA systems. JA11 at 10:8-11; see Unwired Planet, LLC v. Apple

2
at-issue to require a [specific cellular system], it could have included that same
3
limitation.”).
4
Accordingly, the Court will decline to impose a “CDMA or TDMA” limitation into
5
the structure of these terms and will construe the structures as “power level determination
6
means 615 of receiver block 611, and equivalents” and “receiver block 611 and
7
equivalents” respectively. The disclosed structure is receiver block 611, not a CDMA
8
receiver block or a TDMA receiver block. To construe the term otherwise would be against
9
the larger purpose of the patent––to ensure interoperability between different types of

cellular networks.

24
The ‘630 patent describes methods and devices for protecting and maintaining the
25
integrity of the traffic in a cell network connected to two core networks—i.e., one core
26
network for data and another for voice calls. JA13 at Abstract. In particular, this patent
27
addresses a security problem associated with using a single “count parameter” and

5
method avoids the possibility of HFN repetition. Ultimately, the ‘630 patent discloses a

method to increment the counter across all radio bearers such that each new radio bearer

starts with an HFN higher than any HFN used by any radio bearer in a previous session.

11
The parties sole dispute is whether the ‘630 patent recites sufficient structure to
12
perform the recited functions. Apple argues that: (a) Qualcomm has not disclosed adequate
13
corresponding structure to perform all of the claimed functions rendering the claim
14
indefinite, (b) the mobile station itself cannot be the structure and (c) the specification of
15
the ‘630 patent is devoid of any algorithm that could perform the functions. AOCB 9-13.
16
Qualcomm responds that its recitation of structure—a “mobile station having memory and
17
equivalents”––is sufficient.
18
The Court agrees with Apple that a “mobile station having memory” is too indefinite
19
a structure and that adequate structure should have defined the structure and algorithms
20
within the mobile station required to perform the six-part function of this claim. In Net
21
MoneyIn, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1366 (Fed. Cir. 2008), the Federal Circuit—
22
in determining whether a claim recited sufficient structure to rebut the presumption of a
23
means-plus-function claim—held that the claim language “first bank computer containing
24
financial data therein, said financial data including customer account numbers and
25
available credit data, said first bank computer . . . generating an authorization indicia in

to rebut the means-plus-function presumption. The Federal Circuit reasoned that:

the Federal Circuit has suggested is “redundant and illogical.” See id.
13
Qualcomm’s citation to HTC Corp. v. IPCom GmbH & Co., 667 F.3d 1270 (Fed.
14
Cir. 2012) to argue that a “mobile station with memory” is sufficient structure is not only
15
inapposite, but arguably is supportive of Apple’s position that this claim lacks sufficient
16
structure. In HTC, the Federal Circuit found that “[a]lthough the specification here does
17
not literally disclose a processor and receiver, a person skilled in the art would understand
18
that the mobile device would have to contain a processor and a transceiver.” Id. at 1279.
19
Pertinently, the HTC Court did not find that a “mobile station” was sufficient structure for
20
the claimed function of “arrangement for reactivating,” but rather found that a processor
21
and transceiver within the mobile device could set forth sufficient structure for the claimed
22
function. Unlike in HTC where a person of ordinary skill in the art was able to identify
23
that a mobile station usually included a processor and transceiver, here neither Qualcomm,
24
nor its expert Dr. Min has not identified the analogous equivalent of components, such as
25
the processor and transceiver, required to perform the six-part function in the ‘630 patent.
26
Dr. Min concedes that the ‘630 patent describes a “mobile station itself, not any particular
27
component within it.” AEX 16 at 91:13-24. Moreover, Dr. Min stated that the USIM
28
24

1
memory chip could not perform the six-part ciphering process by itself. Id. at 93:19-21.
2
Accordingly, Qualcomm has not disclosed any structure can perform each of the functions
3
described above. See Williamson, 792 F.3d at 1352 (“Where there are multiple claimed
4
functions, as we have here, the patentee must disclose adequate corresponding structure to
5
perform all of the claimed functions. If the patentee fails to disclose adequate
6
corresponding structure, the claim is indefinite.”) (internal citations omitted). Moreover,
7
the Court affords minimal weight to Dr. Min’s reference to the 3GPP standard12 dated after
8
the ‘630 patent as extrinsic evidence “cannot supplant the total absence of structure from
9
the specification.” See Williamson, 792 F.3d at 1354.
10
Finally, Qualcomm’s cited structure is indefinite for a further reason cited in HTC.

To the extent that the mobile station performs the six-part function by means of a processor,

executed by the processor and transceiver. 13 Here, Qualcomm has not identified any
15
algorithm disclosed in the specification of the ‘630 patent.
Rather, Federal Circuit precedent requires the identification of an algorithm
16
Accordingly, the Court concludes that this claim is indefinite for failing to
17
adequately disclose components of the mobile station and algorithms executed by those
18
components that could perform the six-part function recited in the claim.

14
JA37 at 11:63-67.
15
Apple argues that the entire preamble should be construed as a limitation. AOCB
16
14. According to Apple, phrases in the preamble such as “indicating whether its reverse
17
link capacity has been exhausted,” and “each base station in communication with a
18
remote station” exceeds more than a mere description of the intended use of the
19
invention. The preamble defines a limitation by stating that each base station in
20
communication with the remote station sends a reverse link busy bit to the remote station.
21
Moreover, Apple contends that later limitations lack antecedent basis, including that
22
“base stations” appears in the body of claim 1, and the use of “said” in the body relies on
23
the “base stations” defined in the preamble.
24
In its opening brief, Qualcomm concedes two phrases in the preamble are
25
limitations: (1) “each base station in communication with a remote station transmitting a
26
reverse link busy bit” and (2) “the reverse link transmission rate.” QOCB at 19
27
(conceding these aspects of the preamble provide antecedent basis for certain limitations
28
27
17-cv-00108-GPC-MDD
1
recited in the body of the claim). Nonetheless, Qualcomm contends that even when a
2
preamble provides antecedent basis that “does not necessarily convert the entire preamble
3
into a limitation.” Id. (citing TomTom Inc. v. Adolph, 790 F.3d 1315, 1322-24 (Fed. Cir.
4
2015). As such, Qualcomm contends that the remaining terms in the preamble provide a
5
“statement of purpose” for the claim, and are not limitations. These terms would
6
necessarily include:
7
• “In a communication system in which”
8
• “indicating whether its reverse link capacity has been exhausted,”
9
• “a method of determining”
10
• “of said remote station”
11
Both parties cite the “indicating whether its reverse link capacity has been
12
exhausted” language in their interpretation of “reverse link busy bit” below. Given the
13
importance of the “indicating whether its reverse link capacity has been exhausted”
14
language in the construction of “reverse link busy bit,” the Court concludes that this
15
preamble language is necessary to give “life, meaning, and vitality” to the claim by
16
providing a critical definitional limitation of what constitutes a reverse link busy bit. See
17
Catalina Mktg. In’l Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002).
18
By construing this phrase as a limitation, the vast majority of the preamble has
19
either been conceded by Qualcomm to be a limitation or construed by the Court to be a
20
limitation. Accordingly, the Court concludes that the entire preamble is a limitation as
21
that the preamble cannot be parsed into limiting and non-limiting portions. See Blue
22

Next, the parties ask the Court to construe the term “reverse link busy bit.” The
11
parties agree that this term is “information sent by a base station indicating whether” a
12
certain condition exists, and disagree on the construction of this condition. Apple
13
contends that the condition is “whether its reverse link capacity has been exhausted, i.e.,
14
has no remaining capacity.” AOCB at 15. Qualcomm contends that this condition is
15
“whether the base station has reached a reverse link capacity limit.” QOCB at 20.
16
Claim Language
17
The Court begins with an analysis of the claim language. The Preamble of Claim 1
18
of the ‘549 patent states: “In a communication system in which each base station in
19
communication with a remote station transmits a reverse link busy bit indicating whether
20
its reverse link capacity has been exhausted . . .” JA37 at 11:63-67. Apple does not cite
21
any other claim language to support its construction. In its responsive brief, Qualcomm
22
cites claim 9, which states: “the reverse link busy bit indicating when a base station has
23
reached its reverse link capacity limit.” The claim language teaches that the critical term
24
to define here is “exhausted.” The Court turns to the specification to do so.
25
Specification
26
Both parties point to a particular aspect of the specification to support their
27
respective constructions. In describing a mobile station communicating with multiple base
28
29
17-cv-00108-GPC-MDD
1
stations, the specification states:
2
It should be noted that the power control commands from different base
3
stations may have different values and so cannot be combined meaningfully.
4
That is base station 102 may have exhausted its reverse link capacity while
5
base station 104 may still have remaining reverse link capacity, and as such
6
would transmit reverse link busy bits having different values.
7
JA33 at 4:50-56. Qualcomm argues that this embodiment makes clear that exhausted
8
means reaching a capacity limit. QOCB at 21. Apple, on the contrary, asserts that this
9
statement contrasts an “exhausted” reverse link capacity with one that has remaining
10
capacity. AOCB at 16. Apple contends that the patent teaches that the busy “bit” may
11
only have one of two values, either “0” or “1”, indicating that there is one value indicating
12
the base station has “exhausted” its reverse link capacity and “another value indicating the
13
base station ha[s] remaining reverse link capacity.” Id. (citing JA35 at 7:16-17).
14
Apple’s construction fails to take into account that Qualcomm’s construction is not
15
antithetical to the premise that the “bit” value would be zero so long as the base station had
16
“exhausted” its reverse link capacity.
17
“exhausted” as a condition when the base station reaches its “reverse link capacity limit.”
18
Under Qualcomm’s construction, the bit value would be “0” when the base station reaches
19
a reverse link capacity limit, and would be “1” when it has not. Pertinently, the difference
20
is that a reverse capacity limit could be reached while the base station still has some reverse
21
link capacity. As such, a reverse link capacity limit need not have “no remaining capacity.”
22
Accordingly, Apple’s citation to this part of the specification does not support the “has no
23
remaining capacity” definition of “exhausted.” Moreover, the Court agrees that
24
Qualcomm’s construction is more accurately derived from the specification and stays “true
25
to the claim language.” See In re Papst Licensing Digital Camera Patent Litigation, 778
26
F.3d 1255, 1261 (Fed. Cir. 2015).
27
28
Qualcomm’s construction effectively defines
Qualcomm supports its construction by reference to the specification’s repeated
30
17-cv-00108-GPC-MDD
1
statements that a reverse link busy bit indicates when a base station has reached a “reverse
2
link capacity limit.” The Court agrees that this weighs greatly in favor of Qualcomm’s
3
construction. Statements throughout the specification compel the conclusion that a reverse
4
link busy bit indicates whether a link has reached its “capacity limit.” See, e.g., JA32 at
5
2:40-44 (stating that for an exemplary embodiment reverse link busy bits are . . . “indicative
6
of whether the transmitting base station has reached a reverse link capacity limit.”); id. at
7
2:24-27 (“The reverse link busy bit indicates when the base station has reached its reverse
8
link capacity limit.”); JA21 at Abstract (“Reverse link busy bits are independently
9
generated by each base station and indicative of whether the transmitting base station has
10
reached a reverse link capacity limit.”); id. (remote station, in a first exemplary
11
embodiment, transmits a reverse link signal only when all of the reverse link busy bits
12
indicate that the base stations in the remote stations Active Set have reverse link capacity);
13
4:19-21 (“The reverse link busy bits indicate that the reverse link capacity limit of the base
14
station has been reached”); JA34 at 6:43-47 (rate determination element 510 inhibits
15
transmission of the reverse link signal when any of the busy bits from a base station in the
16
Active Set indicate that the reverse link capacity limit for that base station has been
17
reached).
18
Accordingly, Qualcomm’s intrinsic evidence strongly supports a construction that a
19
reverse link busy bit indicates whether the transmitting base station has reached a “reverse
20
link capacity limit.” Further, it supports a construction that “exhausted” in the context of
21
claim 1 of the ‘541 patent means reaching a “reverse link capacity limit.”
22
Extrinsic Evidence
23
Apple contends that the ordinary meaning of exhausted means that capacity is
24
“exhausted” when there is no remaining capacity. See AEX19 at 29 (Webster’s II New
25
College Dictionary defining “exhaust” as “to use up” or wear out completely.”); AEX21 at
26
36 (defining “exhaust” as “consume or use up the whole of”). Qualcomm, relying
27
exclusively on intrinsic evidence, contends that Apple’s extrinsic evidence is not relevant
28
31
17-cv-00108-GPC-MDD
1
in comparison to the definitions provided in the specification and claim language.
2
The Court agrees with Qualcomm. In light of the strength of the intrinsic evidence,
3
Apple’s citations to extrinsic evidence should be afforded minimal weight. See Novartis
4
Pharm. Corp. v. Abbott Labs., 375 F.3d 1328, 1335 (Fed. Cir. 2004) (extrinsic evidence
5
may not “be used to vary, contradict, expand, or limit the claim language from how it is
6
defined, even by implication, in the specification.”). The Court makes a further
7
observation––not all dictionary definitions conclusively support Apple’s “consume
8
entirely” or “use up entirely” construction. For example, Merriam Webster’s Collegiate
9
Dictionary Eleventh Edition (2003) provides alternative definitions of “exhaust,” including
10
“to tire extremely or completely” and “to deprive of a valuable quality or constituent.” 14
11
Such a definition would necessarily indicate that “exhausted” could mean to use up almost
12
entirely.
13
Apple’s expert Jonathan Wells, PhD submitted a declaration that largely repeats and
14
is duplicative of the arguments made in Apple’s opening and responsive claim construction
15
briefing. The Court accordingly affords little weight to the Wells Declaration regarding
16
this patent. See JA260-264. However, the Court does find salient the fact that Dr. Wells
17
conceded in his deposition that the ‘549 patent did not expressly define “exhausted” as “no
18
remaining capacity.” See QEX20 at 77:4-78:16.
19
Court’s Construction
20
Based on the above reasoning, the patent’s claim language, the specification, and the
21
extrinsic evidence, the Court will construe the term “reverse link busy bit” to mean
22
“information sent by a base station indicating whether its reverse link capacity has been
23
exhausted, i.e., whether it has reached a reverse link capacity limit.” By doing so, the Court
24
makes clear that the primary basis of the construction derives from claim 1’s “exhausted”
25
26
27
28
14
The Court observes that the modern Merriam-Webster online dictionary defines “exhausted,” to mean
“completely or almost completely depleted of resources or contents.” See Merriam-Webster, available
at https://www.merriam-webster.com/dictionary/exhausted.
32
17-cv-00108-GPC-MDD
1
language, while recognizing that the entirety of the patent, particularly language in the
2
specification and in another claim, suggests that “exhausted” means reaching a “reverse
3
link capacity limit.” See Philips, 415 F.3d at 1314 (“Because claim terms are normally
4
used consistently throughout the patent, the usage of a term in one claim can often
5
illuminate the meaning of the same term in other claims.”); id. at 1315 (stating that usually
6
the specification is “dispositive; it is the single best guide to the meaning of a disputed
7
term.”).
8
D.
9
The ‘822 patent is an improvement in the acknowledgment process for a base station
10
to grant access to a mobile station, by using location information to reduce the required
11
power to send acknowledgment messages. JA50 at Abstract. Prior to this invention, a
12
mobile station would send a preamble sequence to a base station, which would respond by
13
sending an acknowledgment message—at full power because the base station is unaware
14
of the mobile station’s location—back to the mobile station. JA70 at 2:4-14. The ‘822
15
patent overcomes the issue by dividing the preamble sequences into multiple sets based on
16
different channel qualities. JA70 at 2:18-23. The channel quality is estimated based on a
17
“metric of forward link geometry.” Id. at 2:36-30. The parties dispute the construction of
18
this term.

Claim Language
2
Claim 12 recites an apparatus comprising: “a processor configured to determine a
3
metric of forward link geometry as a function of an observed transmission, wherein said
4
observed transmission is selected from a group consisting of pilot signals, noise, and traffic
5
on data channels, or any combination thereof, and to determine an estimate of channel
6
quality as a function of at least the metric of the observed transmission.” JA75 at 12:8-17.
7
The parties agree that a “metric of forward link geometry” is a measurement of the
8
forward link channel, but dispute whether the measurement is “based on one or more
9
characteristics of the signal” (Qualcomm) or whether the measurement must always use
10
“power and noise.” (Apple).
11
Qualcomm emphasizes the claim language, defining an “observed transmission” as
12
“selected from a group consisting of pilot signals, noise, and traffic on data channels, or
13
any combination thereof.” JA75 at 12:13-15. To Qualcomm, the use of the disjunctive
14
“or” demonstrates that the metric of forward link geometry may, but does not always
15
require both power and noise. Apple, in contrast, cites the “observed transmission” claim
16
language to argue that nothing in this claim states that “forward link geometry” can be
17
calculated without noise.
18
Apple’s argument is a distortion of the plain language of the claim, which clearly
19
indicates that pilot signals [power], noise, and traffic on data channels, “or any combination
20
thereof” could be considered in the metric of forward link geometry. Accordingly, the
21
plain language of the claim language does not support Apple’s construction limiting the
22
construction to require both “power and noise.” Nonetheless, the plain language of the
23
claim also does not support Qualcomm’s overly broad construction requiring only a
24
“measurement of one or more characteristics of a signal.”

specification.
26
27
28
The Court turns to the
Specification
In support of its argument that “forward link geometry” is unambiguously defined
34
17-cv-00108-GPC-MDD
1
to require both power and noise, Apple points to an embodiment in the specification, which
2
states:
3
In an embodiment, observations of forward link geometry are used. For
4
example, metrics such as C/I, where C is the received pilot power and I is the
5
observed noise, may be used. Also C/(C+I) may be used. In other words,
6
some measure that utilizes observed signal power and noise is used.
7
JA 72 at 6:54-59 (emphasis added). According to Apple, this specification language
8
teaches that only power and noise may be used as the requisite metrics of forward
9
link geometry. The Court disagrees. That a single embodiment requires both power
10
and noise as the requisite metric does not mean that that all embodiments of this
11
patent must necessarily also require power and noise. See Williamson, 792 F.3d at
12
1346-47 (cautioning against “limiting the claimed invention to preferred
13
embodiments or specific examples in the specification.”).
14
Qualcomm, meanwhile, points to several points in the specification where the ‘822
15
Patent teaches that the metric of forward link geometry may be determined “as a function
16
of observed pilot signals, noise, and/or traffic on data channels.” JA70 at 2:35-37. See
17
also JA72 at 6:61-7:3 (“For example, Region R1 defines a Region having CQI values
18
corresponding to power and/or noise levels greater than P1.”). Qualcomm argues that this
19
language can, but does not require the use of power and noise, as “and/or” indicates two
20
or more alternatives. The Court agrees with Qualcomm’s construction insofar as the case
21
law clearly indicates that the use of “and/or” indicates two or more alternatives that may
22
be taken together or individually. See Cipher Pharms. Inc. v. Actavis Labs. FL, Inc., 99 F.
23
Supp. 3d 508, 518 (D.N.J. 2015) (“and/or” is a function word to indicate that “two words
24
or expressions are to be taken together or individually.”).
25
The specification, accordingly, makes clear that signal power and noise are
26
unquestionably aspects of the signal that the patent holder intended to be considered as a
27
“metric of forward link geometry.” The pertinent questions, then, are whether (1) power
28
35
17-cv-00108-GPC-MDD
1
and noise are the only characteristics to be considered and (2) whether both power and
2
noise are required in this construction.
3
Prosecution History
4
During prosecution, the applicant amended his original claim—“determining a
5
metric of observed transmission”––to the revised language “determining a metric of
6
forward link geometry as a function of an observed transmission.” See AEX36 at 206.
7
Apple asserts that Qualcomm cannot ignore this explicit limitation. Nonetheless, Apple
8
fails to note that the amended claims in the prosecution history also set forth the limiting
9
definition of “observed transmission” to be “pilot signals, noise, and traffic on data
10
channels, or any combination thereof.” AEX36 at 204, 206. Accordingly, the Court
11
concludes that the prosecution history is of limited value, except to the extent that it
12
reinforces that a metric of forward link geometry was explicitly limited to a specific
13
definition of “observed transmission” such that an observed transmission could constitute
14
“any combination thereof” of “pilot signals, noise, and traffic on data channels.” See
15
AEX36 at 206.
16
Extrinsic Evidence
17
Apple asserts that one of ordinary skill in the art would understand “forward link
18
geometry” to include both power and noise values. See AOCB at 19 (citing AEX22-26––
19
contemporaneous documents from cellular standards organizations). Furthermore, Apple,
20
citing its expert Dr. Bims, asserts that noise is inherently included in the process of
21
determining both a pilot signal or traffic.
22
(“[o]bserved signal power is what is selected from the group of what is received.”). In
23
contrast, Qualcomm’s expert Dr. Villasenor asserts that “geometry” can be used in the
24
wireless communications context to constitute more than signal power and noise. JA449

the extrinsic evidence and is not persuaded that it lends significant support for Apple’s
28
36
17-cv-00108-GPC-MDD
1
construction.
2
3
Construction
Based on the plain language of the claim, the Court concludes that power and noise
4
are not the only aspects that may be included in determining the “metric of forward link
5
geometry.” See JA75 at 12:13-15 (observed transmission is selected from a group
6
consisting of pilot signals, noise, and traffic on data channels, or any combination
7
thereof.”). The plain language, in particular the “any combination thereof” language,
8
indicates that power and noise are not the exclusive parameters of this term. Nonetheless,
9
neither party has offered constructions of other specific elements that can comprise a
10
metric of forward link geometry. At the claim construction hearing, the Court will
11
consider whether other elements such as “traffic on data channels” should be included in
12
any construction.
13
Next, the claim language and specification teach that power or noise is a
14
reasonable reading of “observed transmission” as defined in this claim. See JA75 at
15
12:13-15 (“or any combination thereof.”); JA70 at 2:35-37 (defining metric of forward
16
link geometry as a “function of observed pilot signals, noise, and/or traffic on data
17
channels.”). Given the clarity in the intrinsic evidence, the Court affords minimal weight
18
to Apple’s extrinsic evidence. Accordingly, the Court agrees with Qualcomm to the
19
extent that (1) power and noise are not the exclusive metrics relied upon in this term and
20
(2) that power or noise is an acceptable construction.
21
Nonetheless, Apple is correct that “Qualcomm’s construction, which requires no
22
specific parameters and encompasses any indication of channel quality” is overbroad and
23
frustrates the purpose of the alleged invention. AOCB at 20. Under Qualcomm’s broad
24
construction––“A measurement of one or more characteristics of a signal”—irrelevant
25
characteristics like modulation and frequency that do not provide sufficient information
26
for the base station to capture spatial distance (aka, geometry)––could be considered as
27
part of the metric of forward geometry. This would frustrate the very purpose of the
28
37
17-cv-00108-GPC-MDD
1
invention to transmit information indicating spatial distance and allow for a lower power
2
acknowledgment to a mobile station. See AK Steel Corp. v. Sollac, 344 F.3d 1234, 1239-
3
40 (Fed. Cir. 2003) (claims should be interpreted consistent with stated purposes and
4
goals of the invention). The Court also finds the Declaration of Harry Bims persuasive
5
on this issue where he notes that “Qualcomm’s construction would allow the term
6
‘geometry’ to capture characteristics of the signal that have no relationship to the spatial
7
distance, such as the frequency or modulation of the signal, which is improper.” JA171.
8
Accordingly, based on the claim language, the specification, and the extrinsic
9
evidence, the Court concludes that a “metric of forward link geometry” is a measurement
10
that utilizes “observed power or noise on a forward link channel.”

The ‘469 patent is a method and apparatus for quick retransmission of signals in a
13
communication system. JA85 at 1:8-28. Upon detection of missing or erroneously
14
received packets at a receiving terminal, the receiving terminal uses a quality metric to
15
determine if the packet is correctly received, and then sends a feedback signal to indicate
16
whether retransmission has been requested. JA78 at Abstract.

Claim Language
Independent Claim 1 of the ‘469 patent recites “an apparatus configured to
retransmit signals in a communication system comprising: a decoder configured to
decode contents of a unit of a received signal . . .” JA89 at 10:33-37. Claim 2, a
38
17-cv-00108-GPC-MDD
1
dependent claim, recites “[t]he apparatus of claim 1 wherein the unit of signal is a
2
packet.” JA89 at 10:35-37.
3
Independent claim 11 recites “An apparatus configured to retransmit signals in a
4
communication system, comprising: a decoder configured to decode contents of a unit of
5
received signal.” JA90 at 11:7-9. Claim 2, dependent on this claim, states “[t]he
6
apparatus of claim 11 wherein the unit of signal is a packet.” JA90 at 11:20-21.
7
Apple contends that other elements of claims 1, 11, and 21 require “a quality
8
metric of said unit of signal” and “a preamble of said unit of signal.” JA89 at 10:39-41;
9
JA90 at 11:15-16. This claim language weighs in favor of Apple’s construction as it is
10
11
indicative that a quality metric and preamble are required aspects of unit of signal.
Because the pertinent definition of “packet” is defined in the specification, the
12
Court concludes that the claim language standing alone does not provide any particular
13
insight into the proper construction of “unit of signal” and “unit of received signal.”
14
Specification
15
Apple’s primary argument is that the specification provides a definitive definition of
16
“unit of signal.” Specifically, Apple points to a statement in the “BACKGROUND OF
17
THE INVENTION” subtitled “Description of the Related Art” defining a “packet”:
18
Unless defined differently, a packet is a unit of a signal comprising a
19
preamble, a payload, and a quality metric.
20
JA85 at 1:22-24. As such, the dispute between the parties involves whether a unit of a
21
signal (and received signal) must always comprise a preamble, payload, and quality metric
22
in the context of this patent. Qualcomm asserts that these terms are “straightforward and
23
readily understandable to a jury.”
24
The Court notes that Apple’s constrained definition of “unit of a signal” arises in the
25
context of a definition of the term packet, not a definition of the term unit of signal.
26
Nonetheless, within this definition of packet is a limitation for unit of signal to be used
27
“unless defined differently.”
28
39
17-cv-00108-GPC-MDD
1
Qualcomm asserts that Claim 2 and 12 recite that the “unit of signal is a packet,” and
2
that these dependent claims cannot limit the independent claims in claims 1 and 11 based
3
on the doctrine of claim differentiation. QOCB at 16-17 (citing Trustees of Columbia Univ.
4
v. Symantec Corp., 811 F.3d 1359, 1370 (Fed. Cir. 2016 ) (“Thus, in a situation where
5
dependent claims have no meaningful difference other than an added limitation, the
6
independent claim is not restricted by the added limitation in the dependent claim.”)).
7
Extrinsic Evidence
8
Apple’s expert Dr. Wicker asserts that the claimed invention cannot even work if
9
“unit of signal” does not mean “a preamble, payload, and a quality metric.” Wicker points
10
to Figure 4 of the patent indicating the necessity of the preamble, quality metric, and
11
payload in performing the method outlined in this patent. See JA319 at ¶¶65; JA87-88 at
12
6:63-7:25. Dr. Wicker also asserts that a POSITA would not have found an ordinary
13
meaning to the contested terms at the time the patent was filed. The Court finds this
14
extrinsic evidence persuasive, particularly given the fact that Qualcomm has not presented
15
its own extrinsic evidence to promote any plain and ordinary meaning argument.
16
17
Court’s Construction
The Federal Circuit has recently cautioned against applying the “plain and
18
ordinary” meaning construction. In Eon Corp. v. Silver Springs Networks, 815 F.3d
19
1314, 1317 (Fed. Cir. 2016), Silver Spring asked the district court to construe the terms
20
“portable” and “mobile” in the context of electric watt-hour utility meters attached to the
21
exterior walls of buildings. Id. at 1317. By doing so, Silver Spring wanted a clear
22
construction that portable and mobile did not cover fixed/stationary products that were
23
only “theoretically capable of being moved.” Id. The district court agreed with EON,
24
finding that no construction was necessary as the terms would have been readily
25
understandable to the jury. The Federal Circuit held that the district court erred by failing
26
to resolve the parties’ active dispute about the scope of the terms, and committed legal
27
28
40
17-cv-00108-GPC-MDD
1
error by leaving the question of claim scope unanswered for the jury to decide. Id. at
2
1319 (citing O2 Micro, 521 F.3d at 1362).
3
By granting Qualcomm’s request to construe these terms by their plain and
4
ordinary meaning, the Court would similarly fail to resolve the parties’ active dispute
5
over the scope of the terms “unit of signal” and “unit of received signal.” Here, Apple
6
has provided a defined limitation of what can constitute a unit of signal in the context of
7
the patent (preamble, payload, and quality metric). Qualcomm, meanwhile, offers no
8
construction or definition of what additional components could comprise a “unit of
9
signal.” Just as the Federal Circuit required “portable” and “mobile” to be construed to
10
resolve the active dispute of whether these terms included units only theoretically capable
11
of being moved, so too must this Court resolve the scope of the limits of a “unit of
12
signal” in this patent. See Silver Spring, 815 F.3d at 1319; O2 Micro, 521 F.3d at 1360
13
(“When the parties raise an actual dispute regarding the proper scope of [the] claims, the
14
court, not the jury, must resolve that dispute”). The Court will not leave to the jury to
15
construct a term that the unopposed extrinsic evidence shows has no ordinary meaning to
16
a person of ordinary skill in the art. See JA317 ¶ 61 (Apple’s expert states that “unit of
17
signal” would have had no ordinary meaning to one of skill in the art); 3M Innovative
18
Props. Co. v. Tredegar Corp., 725 F.3d 1315, 1321 (Fed. Cir. 2013) (“Idiosyncratic
19
language, highly technical terms, or terms coined by the inventor are best understood by
20
reference to the specification.”).
21
Qualcomm raises several arguments that rely on claim construction principles that
22
do not have particular weight in this context. Qualcomm’s claim differentiation
23
argument is afforded less weight where the “description provides a clear meaning for the
24
language of the claim in this case” and because such a clear meaning can “trump[] the
25
doctrine of claim differentiation.” O.I. Corp. v. Tekmar Co., Inc., 115 F.3d 1576, 1582
26
(Fed. Cir. 1997). Pertinently, the Federal Circuit has held that “[a]lthough the doctrine of
27
claim differentiation may at times be controlling, construction of claims is not based
28
41
17-cv-00108-GPC-MDD
1
solely upon the language of other claims; the doctrine cannot alter a definition that is
2
otherwise clear from the claim language, description, and prosecution history.” Id. See
3
also Hormone Research Found., Inc. v. Genentech, Inc., 904 F.2d 1558, 1567 n. 15 (Fed.
4
Cir. 1990 (doctrine of claim differentiation “cannot overshadow the express and contrary
5
intentions of the patent draftsman.”). Moreover, Qualcomm fails to even disclose what it
6
thinks the ordinary meaning of “unit of signal”/”unit of received signal” is, citing only a
7
vague definition of “signal” provided by Apple’s expert. The Court agrees with Apple
8
that “[n]o ‘plain and ordinary meaning’ exists” for these terms. ARCB at 9.
9
Accordingly, the Court will accept Apple’s construction. Here, the patentee has
10
provided a definition strongly indicative of the construction of unit of signal/received
11
signal. See Thorner v. Sony Computer Entm’t Am., LLC, 669 F.3d 1362 1365 (Fed. Cir.
12
2012) (noting that plain and ordinary meaning does not apply where a patentee sets out a
13
definition and acts as her own lexicographer). The Court concludes that for purposes of
14
claims 1 and 11, “unit(s) of signal” / “unit of received signal” is “[a] preamble, a payload,
15
and a quality metric.”
16
F.
17
U.S. Patent No. 7,095,725 (“the ’725 Patent”) aims to decrease delays and improve
‘725 Patent
18
data transmission between cell phones and cell towers. JA142 at Abstract. Specifically,
19
the ’725 Patent deals with situations where a cell phone does not have data to transmit,
20
and the data-justified rate subsequently drops to zero. QOCB at 28. A sudden drop in
21
data-justified rate15 causes cell phone delay as the data-justified rate needs time to “ramp
22
back up.” Id. at 29 (citing JA142 at Abstract). The ’725 Patent addresses this issue by
23
24
25
26
27
28
15
The ‘725 patent teaches that “data-justified rate is essentially the maximum rate that can be justified
by the amount of data that is queued for transmission by the access terminal.” JA151 at 2:5-8. If there
is no data in the access terminal’s transmission queue, then no transmission rate at all is justified. JA151
at 10-12. As such, a data-justified rate is the rate warranted in view of how much data the mobile station
needs to send at a given time. A “ramp-up-limited rate is the maximum rate that is allowed, considering
the fact that a rapid ramp-up will suddenly increase the interference perceived by other access terminals
and will degrade their performance.” JA151 at 13-16.
42
17-cv-00108-GPC-MDD
1
the utilization of a “dummy rate” that constrains the data-justified rate “to decrease in a
2
controlled manner” and prevents the rate from suddenly dropping to zero. JA142 at
3
Abstract. The “data-justified rate is compared to the dummy rate and is not allowed to
4
fall below the dummy rate.” JA152 at 3:28-33. Preventing a sudden drop in data-
5
justified rate ensures that a cell phone will not experience delays when the phone
6
increases transmission rate for functions like real-time video.
7
The Parties disagree over “dummy rate” as it appears in Claim 10 of the claim
8
language. 16 JA158 at 16:31-34. This analysis proceeds in two parts. First the Court
9
analyzes whether dummy rate should be construed to “decay” or “decrease.” Apple
10
describes “dummy rate” as a rate which can “decay in a predetermined manner.”
11
Qualcomm describes “dummy rate” as being able to “decrease in predetermined manner
12
over time without reaching zero.” Id. (emphasis added). Second, the Court analyzes
13
whether the term “dummy rate” should include a negative limitation indicating that a
14
dummy rate cannot reach zero.

Specification
Apple argues “dummy rate” “is not a common, well-understood term” in the
wireless telecommunications community, and the best source of interpretation is the
patent specification. AOCB at 29. Apple refers to language from the patent specification
that states:
“[T]he decrease in the second data transmission rate is constrained by
controlling decreases in the data-justified rate. This is accomplished in one
embodiment by maintaining a dummy rate which is allowed to decay in a
predetermined manner. The conventionally calculated data-justified rate is
compared to the dummy rate and is not allowed to fall below the dummy rate.”
Id. at 29-30 (quoting JA152 at 3:27-31) (emphasis added). Apple describes this process
as “a controlled decay” that satisfies the ’725 Patent’s stated goal. AOCB at 30. The
patent specification mentions “decay” when describing “dummy rate” in two other
instances: (1) in a description of how the processor controls the data-justified rate through
“maintaining a “dummy rate” which is caused to decay in a predetermined manner.”
JA152 at 3:49-53 and (2) in a description stating that the “dummy rate” can “prematurely
decay” in response to changes in data-justified rate. JA156 at 11:55-61.
44
17-cv-00108-GPC-MDD
1
Qualcomm references the Abstract to argue that “dummy rate” constrains the data-
2
justified rate “to decrease in a controlled manner.” QOCB at 29 (quoting JA142 at
3
Abstract). The patent specification introduces the term “decay factor.” JA 142-59. A
4
“decay factor” can be used “to decrease the value of a dummy rate.” JA156 at 11:26-28.
5
Extrinsic Evidence
6
Apple’s expert witness, Dr. Jonathan Wells, gives a declaration in support of
7
Apple’s claim construction brief. Joint Ex. 11. In his declaration, Dr. Wells suggests that
8
a personal of ordinary skill in the art (“POSITA”) for the ’725 Patent has a bachelor’s
9
degree in engineering and two-plus years of experience with telecommunications
10
networks. Dkt. No. 301-1 at 245. Dr. Wells considers himself a POSITA. Id. He
11
believes the patent specification supports use of “decay” and specifically allows the
12
“dummy rate” to “prematurely decay.” Id. at JA248-50. Dr. Wells argues that
13
Qualcomm fails to cite any extrinsic evidence in support of its construction, and given
14
Apple’s intrinsic evidence, a POSITA would understand “dummy rate” as “a rate which
15
is allowed to decay in a predetermined manner.” Id. at JA255-57. Dr. Wells contends
16
Qualcomm’s use of “may decrease” instead of “decay” does not carry the same
17
connotation to a POSITA. Id. at 293.
18
Qualcomm chooses not to provide any extrinsic evidence. Apple argues that
19
Qualcomm is unable to provide any extrinsic evidence that supports Qualcomm’s
20
construction. AOCB at 30.
21
Court’s Construction
22
Courts consider intrinsic evidence to be “the most significant source of the legally
23
operative meaning of disputed claim language.” Vitronics Corp., 90 F.3d at 1582. Most
24
of the time, analyzing “the intrinsic evidence alone will resolve any ambiguity in a
25
disputed claim term. Id. at 1583. Here, because “decay” and “decrease” appear multiple
26
times in the intrinsic evidence and both parties cite to the intrinsic evidence, the Court
27
determines that intrinsic evidence alone is sufficient to resolve this dispute. See Pall
28
45
17-cv-00108-GPC-MDD
1
Corp. v. Micron Separations, Inc., 66 F.3d 1211, 1216 (Fed. Cir. 1995) (suggesting that
2
in situations where intrinsic evidence is sufficient to determine the meaning of a disputed
3
term, a court should not rely on extrinsic evidence). Accordingly, the Court will not rely
4
on the Wells Declaration for purposes of this analysis. See Markman, 52 F.3d at 979.
5
The Court finds that although “decrease” is not used to describe “dummy rate” in
6
Claim 10, the fact that dummy rate is described as a “decrease” in other parts of the
7
surrounding claim language weighs significantly in favor of Qualcomm’s construction.
8
See Conoco, Inc. v. Energy & Environmental Intern., L.C., 460 F.3d 1349, 1362 (Fed.
9
Cir. 2006) (“search for the ordinary and customary meaning of a claim term” can “be
10
informed by the surrounding claim language”). Further, the Court determines that
11
because “decrease” is found in surrounding claim language and because the patent
12
specification does not offer an explanation for using “decay” instead of “decrease” in
13
several instances, “decay” is essentially a synonym for “decrease” and not a replacement.
14
See Anderson Corp. v. Fiber Composites, LLC, 474 F.3d 1361, 1368 (Fed. Cir. 2007)
15
(determining that that “composite material” was just a synonym for “composite
16
composition” and not an entirely different expression.). The claim language favors the
17
use of “decrease” over “decay,” and the Court will construe the term accordingly.
18
19
20
2.
“dummy rate” –– reaching zero
a) Claim Language
There is no claim language that addresses whether “dummy rate” can reach zero.
21
The Court turns to the specification to address this issue.
22
b) Specification
23
Apple contends that nothing in the intrinsic evidence suggests that the “dummy
24
rate” cannot reach zero, and indeed that the patent specification provides specific
25
examples where the “dummy rate” does drop to zero. AOCB at 30 (citing JA156 at
26
11:64-12:05). In its response brief, Apple argues that because Qualcomm stresses the
27
importance of preventing “sudden” drops of data-justified rate so frequently, preventing
28
46
17-cv-00108-GPC-MDD
1
“sudden” drops is the true purpose of the ’725 Patent, and Apple’s construction
2
accomplishes this purpose. ARCB at 13-14. Apple contends that Qualcomm fails to
3
provide any specific examples as to why the “dummy rate” cannot reach zero. Id. Apple
4
argues “Qualcomm’s construction improperly grafts on the negative limitation that the
5
rate cannot equal zero.” AOCB at 30 (citing Omega Eng’g, Inc. v. Raytek Corp., 334
6
F.3d 1314, 1323 (Fed. Cir. 2003)).
7
Qualcomm argues that both the intrinsic evidence and purpose of a “dummy rate”
8
support construing “dummy rate” to be a rate that cannot reach zero. QOCB at 29.
9
According to Qualcomm, allowing the data-justified rate to drop to zero creates delays in
10
transmitting time-sensitive data, and that this is precisely what the ’725 Patent aims to
11
prevent. Id. Qualcomm explains the “dummy rate,” as described in the ’725 Patent,
12
prevents such sudden drops by not allowing the data-justified rate to fall below the
13
“dummy rate.” Id. Qualcomm posits that because the data-justified rate can never be a
14
negative number and the “dummy rate” need always be below the data-justified rate, the
15
“dummy rate” can never reach zero. Id. at 30. The “Abstract” supports this notion by
16
stating “the data-justified rate is constrained to decrease in a controlled manner and
17
cannot suddenly drop to 0.” JA 142 at Abstract. Qualcomm argues that, because one of
18
the purposes of the ’725 Patent is to prevent the data-justified rate from reaching zero,
19
allowing the “dummy rate” to reach zero would frustrate the purpose of the invention. Id.
20
at 30. Qualcomm contends that Apple’s construction would allow the data-justified rate
21
to reach zero and thus require the cell phone to ramp up the data-justified rate from zero,
22
thus causing sporadic data transmission, something the ’725 Patent is designed to
23
prevent. Id. Qualcomm claims it is allowed to impose a “negative claim limitation” on
24
the rate because the contention is “adequately supported” and “the specification describes
25
a reason to exclude the relevant limitation.” QRCB at 15 (citing Santarus, Inc. v. Par
26
Pharm., Inc., 694 F.3d 1344, 1351 (Fed. Cir. 2012)).

c) Extrinsic Evidence
Apple’s expert Dr. Wells contends the patent specification gives specific examples
3
where the “dummy rate” reaches zero. JA255 at 255. Dr. Wells posits that the “dummy
4
rate’s” purpose is to prevent sudden drops in data-justified rate and not to prevent the
5
data-justified rate from reaching zero. JA256 at 1. Dr. Wells argues that Qualcomm’s
6
construction, by stating the “dummy rate” “may decrease,” allows the “dummy rate” to
7
“decrease” from a high numeric value to zero, thus defeating the purpose of “dummy
8
rate” as found in the ’725 Patent. JA293 at 2. Qualcomm claims it does not provide any
9
extrinsic evidence because its construction comes directly from the intrinsic evidence.
10
11
12
QRCB at 15.
Court’s Construction of Dummy Rate
As stated in the previous section, because both parties base their arguments off of
13
the patent specification, the Court finds intrinsic evidence alone sufficient for purposes of
14
this analysis. See Pitney Bowes, Inc., 182 F.3d at 1308-09.
15
The Court recognizes that the patent specification includes an embodiment wherein
16
an access terminal initially transmitting at a “rate index of 5” would take five frames at a
17
decay factor of .5 to drop to a “0 rate index.” See JA156 at 11:64-12:8; JA255 ¶ 136. Yet,
18
as Qualcomm points out, this description takes place in the context of a description of an
19
“access terminal’s” rate index, not a description of the dummy rate’s transmission rate.
20
Further, any weight this aspect of the embodiment provides to Apple’s construction is
21
negligible because accepting Apple’s overall construction would frustrate the overall
22
purpose of the invention. See QRCB at 9-10.
23
A party arguing that a particular interpretation would “frustrate the purpose of the
24
invention” must adequately explain their reasoning. See Atlantic Construction Fabrics,
25
Inc. v. Dandy Products, Inc. 64 F. App’x 757 (Fed. Cir. 2003) (determining that plaintiff
26
failed to explain why a certain interpretation would “completely frustrate the purpose of
27
the invention.”). Qualcomm does so. According to the specification a primary purpose
28
48
17-cv-00108-GPC-MDD
1
of the invention is that “the data-justified rate is constrained to decrease in a controlled
2
manner and cannot suddenly drop to 0.” JA142 at Abstract. The patent specification
3
teaches that the “data-justified rate is compared to the dummy rate and is not allowed to
4
fall below the dummy rate.” JA152 at 3:30-33. Thus, it follows that a dummy rate of
5
zero would frustrate the purpose of the ‘725 Patent to prevent the data-justified rate from
6
reaching zero. Apple argues “Qualcomm’s construction improperly grafts on the
7
negative limitation that the rate cannot equal zero.” AOCB at 30 (citing Omega Eng’g,
8
334 F.3d at 1323). Qualcomm responds that it is allowed to impose a “negative claim
9
limitation” on the rate because its contention is “adequately supported” and “the
10
specification describes a reason to exclude the relevant limitation.” QRCB at 15 (quoting
11
Santarus, 694 F.3d at 1351).
12
The Court agrees with Qualcomm’s construction. Allowing the “dummy rate” to
13
reach zero would allow the data-justified rate to reach zero. For example, an embodiment
14
in the patent teaches that the conventionally calculated data-justified rate is compared to
15
the dummy rate and is not allowed to fall below the dummy rate. JA152 at 3:30-33.
16
Figure 5 confirms that there would be essentially no purpose to a dummy rate that
17
reaches zero. The patent teaches that in an embodiment a decay factor is used in an
18
embodiment to decrease the value of a dummy rate, wherein a tentative rate is calculated
19
in a normal manner and that is compared to a dummy rate, and the R3 data-justified rate
20
becomes set to the higher of the tentative rate or dummy rate. JA156 at 11:1-54. If a
21
dummy rate were allowed to be zero, the data-justified rate would never rely on the zero
22
dummy rate and would always be the tentative data-justified rate, and thus would not
23
further the purpose of this invention. Accordingly, because a dummy rate that can reach
24
zero frustrates a primary purpose of the invention to reduce delays in the transmission of
25
“bursty” data, the Court will construe the term to include the “without reaching zero”
26
language. The Court finds Apple does not provide adequate support to “narrow the
27
28
49
17-cv-00108-GPC-MDD
1
negative claim limitation.” Imaginal Systematic, LLC v. Leggett & Platt, Inc., 805 F.3d
2
1102, 1110 (Fed. Cir. 2015).
3
Apple posits that preventing “sudden” drops in data-justified rate is the true
4
purpose of the ’725 Patent and its construction accomplishes this purpose. ARCB at 14.
5
The Court does not view the prevention of sudden drops in data-justified rate and
6
prevention of the “dummy rate” from reaching zero to be mutually exclusive, but rather
7
two concepts that compliment one another. 3M Innovative Properties Co. v. Tredegar
8
Corp., 725 F.3d 1315, 1330 (Fed. Cir. 2013) (“Rather than being mutually exclusive, the
9
concepts of [the two terms] are linked.”). Indeed, preventing a dummy rate of zero is
10
instrumental in furthering the goal of preventing a sudden drop in data-justified rate. The
11
Court finds that the “dummy rate” should not be allowed to reach zero, as allowing the
12
“dummy rate” to reach zero would frustrate a primary purpose of the invention.
13
For the foregoing reasons, the Court determines the proper construction of
14
“dummy rate” is the following: “a rate that may decrease in a predetermined manner over
15
time without reaching zero.” 17

MOTION TO STRIKE
2
On February 14, 2018, Qualcomm filed a Motion to Strike Apple’s First and Second
3
Amended Invalidity Contentions. Dkt. No. 331. Apple and the Contract Manufacturers
4
filed a response on March 1, 2018. Dkt. No. 345.
5
Pursuant to the Court’s Case Management Order Regulating Discovery and Other
6
Pretrial Proceedings for Patent Claims, Apple and the CMs filed Joint Invalidity
7
Contentions on October 30, 2017. Dkt. No. 117 ¶ 2; Ex. A. Claim construction discovery
8
concluded on January 11, 2018. Dkt. No. 117 ¶ 6. On January 3, 2018, Apple served
9
Qualcomm with a set of first Amended Joint Invalidity Contentions. Ex. B. On January
10
11, 2018, Apple served Qualcomm with a second set of Amended Invalidity Contentions
11
(“Second Amended Invalidity Contentions.”). Ex. C.
12
Qualcomm argues that the plain language of Patent Local Rule 3.6(b) states that that
13
only a “party opposing a claim of patent infringement” may serve “as a matter of right”
14
amended invalidity contentions. Patent L.R. 3.6(b). According to Qualcomm, Apple and
15
the CMs are not parties “opposing a claim of patent infringement” as Qualcomm has never
16
counterclaimed that Apple infringes the nine patents-in-suit. See, e.g., Dkt. No. 72.
17
The plain language of the Magistrate Judge’s scheduling order makes clear that he
18
considered Apple a party “opposing a claim of patent infringement” and made a specific
19
scheduling determination to allow Apple to amend its Invalidity Contentions as of right up
20
and until January 11, 2018, the date of completion of claim construction discovery.
21
Notably, the Magistrate Judge’s Order recognized that Qualcomm was not claiming
22
infringement, and yet the Scheduling Order still included a date for a party––which can
23
only be Apple under any plain reading––to file as of right Amended Invalidity Contentions.
24
Under any common sense interpretation of the scheduling order, it is apparent that the
25
Magistrate Judge was allowing for a slight alteration in the Patent Local Rules to take into
26
27
28
53
17-cv-00108-GPC-MDD
1
account the procedural posture of the case. 18 This interpretation is confirmed by a review
2
of the Patent Local Rules template wherein the Magistrate Judge removed the deadline for
3
filing as of right Amended Infringement Contentions under Local Rule 3.6(a), but retained
4
the deadline for filing as of right Amended Invalidity contentions. See Dkt. No. 117 ¶¶ 5-
5
7.
6
This Court’s prior ruling in Zest IP Holdings, LLC v. Implant Direct Mfg., LLC, No.
7
10CV0541-GPC-WVG, 2013 WL 5674834, at *7 (S.D. Cal. Oct. 16, 2013) is inapposite.
8
There, the Court considered a motion to file amended infringement contentions after the
9
deadline for “matter of right” amendment deadline had already passed. There, the Court
10
held that the addition of thirty prior art references would have resulted in undue prejudice
11
to Zest, though the Court granted the motion to amend invalidity contentions as to a single
12
prior art reference. Local Rule 3.6(b) states: “As a matter of right, a party opposing a claim
13
of infringement may serve ‘Amended Invalidity Contentions’ no later than the completion
14
of claim construction discovery. Thereafter, absent undue prejudice to the opposing party,
15
a party opposing infringement may only amend its invalidity contentions . . .” Here, Apple
16
served their amended contentions by the date of completion of claim construction
17
discovery. Accordingly, Zest is irrelevant to the instant question because Apple––under a
18
plain reading of the scheduling order––was still within its period to file “matter of right”
19
Amended Invalidity Contentions.
20
Qualcomm has also waited too long to challenge the scheduling order’s ambiguous
21
provision. Qualcomm was on full notice of the scheduling order as of August 18, 2017
22
and never challenged the scheduling order or sought clarification of the ambiguous
23
paragraph. For example, Qualcomm could have submitted an inquiry to Magistrate Judge
24
Dembin to clarify the scope of the scheduling order. Pertinently, Qualcomm had more than
25
26
27
28
18
Nothing in this Order should read to hold that a party seeking a declaratory judgment in the Southern
District of California will always be considered a party “opposing a claim of patent infringement” entitled
to an amendment as of right. This Order is limited to a specific ambiguity in the Scheduling Order issued
in this case.
54
17-cv-00108-GPC-MDD
1
five months to submit a request for clarification or a challenge to the Scheduling Order.
2
Even if Qualcomm had not carefully parsed through the nuances of the scheduling order,
3
it certainly was on notice as of January 3, 2018 (the date Apple served their first Amended
4
Invalidity Contentions), that Apple believed it had an “as of right” amendment right based
5
on the scheduling order. Yet, no motion for clarification or motion to strike was filed at
6
that time.
7
Further, Qualcomm has not shown diligence in challenging any transgression by
8
Apple. It was served with the Second Amended Invalidity Contentions on January 11,
9
2018, and yet did not file a Motion to Strike these Contentions until February 14, 2018,
10
more than a month after Apple’s document was served. See Dkt. No. 331.
11
Next, Qualcomm further contends that the Amended Invalidity Contentions are
12
deficient under the Patent Local Rules by failing to sufficiently explain their asserted
13
grounds of indefiniteness and lack of written description under Patent Local Rule 3.3(d).
14
Courts have held that the level of detail required for invalidity contentions is lower than
15
that required for a claim of obviousness but still must “give the other party enough notice
16
that it can engage in full, timely discovery and litigate its case.” Medimmune LLC v. PDL
17
Biopharma, Inc., No. C-08-5590, 2010 WL 760443, at *3 (N.D. Cal. Mar. 4, 2010).
18
Apple’s First Amended Invalidity Contentions presented sufficiently adequate contentions
19
to provide Qualcomm with notice of its theories of invalidity. See, e.g., Ex. B at 143-44
20
(describing indefiniteness theory based on failure to disclose corresponding structures as
21
to ‘630 patent). Moreover, the Court finds that Apple’s Invalidity Contentions provide
22
adequate detail, including through claim charts, concerning the background knowledge of
23
skilled artisans and sufficiently specific reasons as to why skilled artisans would have
24
combined/modified references. These references include nearly 5,000 pages in detailed
25
analysis. See, e.g., Dkt. No. 331-2, AEX. C. Further, Apple has provided far more detail
26
in its invalidity contentions than the contentions rejected in MediaTek Inc. v. Freescale
27
Semiconductor, Inc., 2014 WL 690161, at *6 (N.D. Cal. Feb. 21, 2014) (invalidity
