SAMSUNG ELECTRONICS CO., LTD., et

11
United States District Court
Northern District of California
Defendants.
12
On May 26, 2017, MobileMedia Ideas LLC (“MMI”) filed this patent infringement action
13
14
against Defendants Samsung Electronics Co., Ltd., and Samsung Electronics America, Inc.
15
(collectively, “Samsung”). Dkt. No. 1 (“Compl.) On March 27, 2017, MMI assigned the patents-
16
in-suit to Ironworks Patents LLC (“Ironworks”). Dkt. No. 66-2. And on July 6, 2017, this Court
17
permitted Ironworks to replace MMI as the Plaintiff. Dkt. No. 92. The parties now seek
18
construction of eight terms found in two patents: Patent Nos. 6,427,078 (“the ’078 Patent”), and
19
5,915,239 (“the ’239 Patent”) (collectively, “the Asserted Patents”).1 This order follows claim
20
construction briefing, a technology tutorial, and a claim construction hearing.
21
I.
LEGAL STANDARD
Claim construction is a question of law to be determined by the Court. Markman v.
22
23
Westview Instruments, Inc., 517 U.S. 370, 384 (1996). “The purpose of claim construction is to
24
determine the meaning and scope of the patent claims asserted to be infringed.” O2 Micro Int’l
25
Ltd. v. Beyond Innovation Tech. Co., 521 F.3d 1351, 1360 (Fed. Cir. 2008) (quotation omitted).
26
27
28
Despite initially proposing constructions of the term “at least one memory unit for storing said
image information,” the parties now agree that the Court need not construe that term. See Dkt.
No. 124-1, at 3 (proposing construction); Dkt. No. 157 at 6:1–4 (noting that the parties “reached
an agreement on that, and it doesn’t need to be construed”).
1
1
Generally, claim terms should be “given their ordinary and customary meaning”—in other
2
words, “the meaning that the term[s] would have to a person of ordinary skill in the art in question
3
at the time of the invention.” Phillips v. AWH Corp., 415 F.3d 1303, 1312–13 (Fed. Cir. 2005) (en
4
banc) (quotation omitted). There are only two circumstances where a claim is not entitled to its
5
plain and ordinary meaning: “1) when a patentee sets out a definition and acts as his own
6
lexicographer, or 2) when the patentee disavows the full scope of a claim term either in the
7
specification or during prosecution.” Thorner v. Sony Computer Entm’t Am. LLC, 669 F.3d 1362,
8
1365 (Fed. Cir. 2012).
9
When construing claim terms, the Federal Circuit emphasizes the importance of intrinsic
evidence such as the language of the claims themselves, the specification, and the prosecution
11
United States District Court
Northern District of California
10
history. Phillips, 415 F.3d at 1312–17. The claim language can “provide substantial guidance as
12
to the meaning of particular claim terms,” both through the context in which the claim terms are
13
used and by considering other claims in the same patent. Id. at 1314. The specification is likewise
14
a crucial source of information. Id. at 1315–17. Although it is improper to read limitations from
15
the specification into the claims, the specification is “the single best guide to the meaning of a
16
disputed term.” Id. at 1315 (noting that “the specification is always highly relevant to the claim
17
construction analysis,” and that “[u]sually, it is dispositive” (quotation omitted)); see also Merck
18
& Co. v. Teva Pharm. USA, Inc., 347 F.3d 1367, 1371 (Fed. Cir. 2003) (explaining that “claims
19
must be construed so as to be consistent with the specification”).
20
Despite the importance of intrinsic evidence, courts may also consider extrinsic evidence—
21
technical dictionaries, learned treatises, expert and inventor testimony, and the like—to help
22
construe the claims. Phillips, 415 F.3d at 1317–18. For example, dictionaries may reveal what
23
the ordinary and customary meaning of a term would have been to a person of ordinary skill in the
24
art at the time of the invention. Frans Nooren Afdichtingssystemen B.V. v. Stopaq Amcorr
25
Inc., 744 F.3d 715, 722 (Fed. Cir. 2014) (“Terms generally carry their ordinary and customary
26
meaning in the relevant field at the relevant time, as shown by reliable sources such as
27
dictionaries, but they always must be understood in the context of the whole document—in
28
particular, the specification (along with the prosecution history, if pertinent).”). Expert testimony
2
1
can also help “to ensure that the court’s understanding of the technical aspects of the patent is
2
consistent with that of a person of skill in the art, or to establish that a particular term in the patent
3
or the prior art has a particular meaning in the pertinent field.” Phillips, 415 F.3d at 1318.
4
Extrinsic evidence is, however, “less significant than the intrinsic record in determining the legally
5
operative meaning of claim language.” Id. at 1317 (quotation omitted).

“camera unit” (’078 Patent)
Ironworks’s Construction
Plain and ordinary meaning, no
construction necessary.

27
28
If construed: “a data collection apparatus
for obtaining image information”
Samsung’s Construction
“camera arrangement comprising a camera,
optics, microprocessor and memory, battery,
and interface to external systems constituting an
individual component of a whole personal
communication device or whole portable
mobile cellular phone”
The Court adopts Samsung’s construction.
4
The term “camera unit” appears in independent claims 1, 36, and 73, and dependent claims
1
2
18, 38, and 46 of the ’078 Patent. JCCS, App. A at 1. Ironworks argues that “each of [the] three
3
independent claims defines . . . ‘camera unit’ differently,” such that no one claim is representative.
4
See Op. Br. at 9–11 (discussing MobileMedia Ideas LLC v. Apple Inc. (“MMI”), 780 F.3d 1159

21
Despite Ironworks’s assertion that each independent claim “defines . . . ‘camera unit’
22
differently,” Ironworks simultaneously argues that the Court need not construe the term because it
23
is unambiguous. Op. Br. at 10–11. Instead, Ironworks asks the Court to give the term its “plain
24
and ordinary meaning.” Id. Ironworks also contends that “camera unit,” if construed, means “a
25
data collection apparatus for obtaining image information.” Id. The phrase “data collection
26
apparatus” does not appear in any of the claims. Also, Ironworks’s opening brief offered no
27
intrinsic or extrinsic evidence to support that construction. Ironworks’s reply, however, notes that
28
a Delaware district court adopted its alternative construction in MobileMedia Ideas, LLC v. Apple
6
1
Inc., 907 F. Supp. 2d 570, 601 (D. Del. 2012), vacated in part, 780 F.3d 1159 (Fed. Cir. 2015).
2
See Reply Br. at 1. Ironworks adds that neither party to that case appealed the court’s construction
3
of “camera unit.” Id.
4
Ironworks further contends that Samsung’s proposed construction improperly (1) imports
5
additional limitations absent from some claims, and (2) renders other claims redundant by setting
6
out the same elements already recited in those claims. Op. Br. at 12. To that end, Ironworks
7
asserts that both claim 1 and claim 73 define for that claim only what a camera unit “comprises,”
8
with the latter stating fewer requirements than the former. Id. Ironworks contends that accepting
9
one interpretation of camera unit for all claims would thus create confusion. Id.
The Court disagrees with Ironworks’s arguments and adopts Samsung’s construction. To
10
United States District Court
Northern District of California
11
begin, this Court must construe the term “camera unit,” because the term is ambiguous.
12
Ironworks’s own position invites ambiguity: if the Court accepts that independent claims use
13
“camera unit” differently, then the term’s meaning necessarily varies. Moreover, while Ironworks
14
separately contends that construction is unnecessary because the Court can adopt the term’s plain
15
and ordinary meaning, Ironworks provides no such plain and ordinary meaning. See O2 Micro
16
Int'l Ltd., 521 F.3d at 1361 (“A determination that a claim term ‘needs no construction’ or has the
17
‘plain and ordinary meaning’ may be inadequate when a term has more than one ‘ordinary’
18
meaning or when reliance on a term’s ‘ordinary’ meaning does not resolve the parties’ dispute.”)
19
Further, Ironworks cites no expert testimony or any other external reference to describe how a
20
skilled artisan would understand the term “camera unit” at the time of the invention. See Phillips,
21
415 F.3d at 1312–13.
Apart from the general flaws in Ironworks’s arguments, the Federal Circuit has addressed
22
23
the camera unit term at issue here, and its analysis is instructive.3 See MMI, 780 F.3d 1159
24
(discussing the ’078 Patent). That case highlighted that “[t]he specification explains that the
25
structure of the camera unit ‘conforms to the block diagram shown in Fig[ure] 5’ of the ’078
26
27
28
Although the Federal Circuit considered the meaning of the term “means for processing and for
storing” image information as it appears in claim 73, Ironworks has not asserted that this function
differs by claim. See MMI, 780 F.3d at 1167.

And as the Federal Circuit noted: “Figure 5 illustrates that the camera unit includes a
14
‘camera 14a and optics 15b, image processing unit 14c, [and] battery 21.’ The camera unit's
15
image processing unit is a ‘microprocessor 23’ and ‘a number of memory units 24.’” Id. (citing
16
‘078 Patent, 4:23–31, 4:37–41). This finding tracks Samsung’s proposed construction.4
The Court further disagrees with Ironworks’s characterization of Samsung’s construction
17
18
as either overly limiting or redundant. In arguing that each claim defines “camera unit” for the
19
purpose of only that claim, Ironworks contrasts the “comprising” language of claims 1 and 73.
20
See Op. Br. at 12. Ironworks points out that the camera unit in claim 1 comprises: “a camera,
21
optics, means for processing and for storing, a memory unit, and an output.” Id.; see also ’078
22
Patent, 7:51–60. Ironworks describes claim 73, in contrast, as comprising “optics, an image
23
sensor, and a means for processing and for storing.” Op. Br. at 12; see also ’078 Patent, 16:13-18.
24
But claim 73’s language makes clear that “image sensor” is effectively equivalent to the word
25
26
27
28
The Court acknowledges that the Delaware district court adopted Ironworks’s “if construed”
proposal. See MobileMedia Ideas, LLC., 907 F. Supp. 2d at 601. But the Court respectfully
declines to endorse that construction, in part because the only line of the specification relied upon
by the Delaware court describes the function of the camera and not what it comprises. See id.
(discussing ’078 Patent, 3:66).
8
4
1
“camera” as used in claim 1. Compare Claim 1, 2012 ’078 Patent, 1:46 (describing “a camera for
2
receiving image information”), with Claim 73, ’078 Patent, 16:16 (describing “an image sensor
3
for obtaining image information”). If those terms were not substantively equivalent, then claim
4
73’s “camera unit” would disclose no “camera” at all, which is inconsistent with the plain
5
language of the claim. The only other distinction between these claims’ “camera unit . . .
6
comprising” language is claim 1’s recitation of an “output.” “Output,” however, does not appear
7
in Samsung’s construction.
Although Samsung’s construction includes specific elements—e.g., “battery”—not present
8
9
10
in independent claims 1, 36, and 73, the specification nonetheless supports Samsung’s
construction:
United States District Court
Northern District of California
11
14
In principle, the structure of both camera card 15 and camera unit 14
conforms to the block diagram shown in FIG. 5. By example,
camera card 15 consists of camera arrangement 140 which
comprises camera 14a and optics 14b image processing unit 14c,
battery 21 and interface 22 to external systems . . . . Image
processing unit 14c comprises microprocessor 23 and a number of
memory units 24.
15
See ’078 Patent, 4:23–31. Ironworks argues that this discussion refers to Figure 2, which provides
16
“an example of the notebook computer application of the invention.” Op. Br. at 12–13. The Court
17
disagrees. Although the text above uses the word “example,” it also expressly refers to Figure 5,
18
which “shows a block diagram of the camera unit.” ’078 Patent, 2:11. The specification does not
19
limit Figure 5 to one embodiment. Figure 5, in turn, contains the elements set forth in the above-
20
quoted text. And as noted above, the Federal Circuit relied on this text and Figure 5 to identify the
21
camera unit’s structure. See MMI, 780 F.3d at 1168–71 (“The specification explains that the
22
structure of the camera unit ‘conforms to the block diagram shown in Fig[ure] 5’ . . . .”); Resp. Br.
23
at 8.
12
13
24
Ironworks urges the Court not to limit the claims based on the specification. Op. Br. 13–
25
14. But this Court cannot ignore that the specification is “the single best guide to the meaning of a
26
disputed term.” See Phillips, 415 F.3d at 315; Edwards Lifesciences LLC v. Cook Inc., 582 F.3d
27
1322, 1331 (Fed. Cir. 2009) (holding that the district court properly construed a claim to include
28
the element of “wires” where “every embodiment described in the specification and shown in the
9

drawings includes wires”).

The Court adopts Samsung’s construction for the function, but adopts the following
13
construction for the structure: “microprocessor (23) and memory unit (24) within the
14
camera unit.”
15
The term “means for processing and for storing . . . image information . . .” appears in
16
independent claim 1 of the ’078 Patent. See JCCS, App. A at 1–2. Ironworks again disputes
17
whether the term as used in that claim is representative of how the term is used in the claim
18
language. Op. Br. at 14–16. The term also appears in independent claim 73, but the parties do not
19
ask the Court to construe the term as set forth in that claim. For purposes of the analysis that
20
follows, however, the following table sets forth how independent claims 1 and 73 use the term:

20
21
Samsung accurately characterizes this term as a means-plus-function term subject to 35
22
U.S.C. § 112 (“Section 112”). A claim invokes Section 112 if the claim limitation is drafted in the
23
means-plus-function format. See Robert Bosch, LLC v. Snap-On Inc., 769 F.3d 1094, 1097 (Fed.
24
Cir. 2014) (“The use of the term ‘means’ triggers a rebuttable presumption that § 112, ¶ 6 governs
25
the construction of the claim term.”). Here, the term expressly includes the word “means,” and
26
Ironworks does not rebut that presumption.
27
28
Given that Section 112 applies, the Court’s analysis is two-fold: the Court (1) identifies the
claimed function; and then (2) determines what structure, if any, is disclosed in the specification
11
1
that corresponds to these functions. Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1351–52
2
(Fed. Cir. 2015). Structure disclosed in the specification must be “corresponding structure,”
3
which is satisfied “if the intrinsic evidence clearly links or associates that structure to the function
4
recited in the claim.” Id. at 1352. Even where structure is corresponding, it must also constitute
5
“adequate corresponding structure to achieve the claimed function.” Id. (quotation omitted).
6
The parties here agree that the claimed function is “processing and storing at least a portion
7
of said image information obtained by said camera unit for later recall and processing.” The
8
parties dispute, however, what structure corresponds to the claimed function. Ironworks’s
9
proposed structure is “microprocessor 23 and equivalents.” See Op. Br. at 14. Samsung’s
proposed structure is “microprocessor (23) and memory (24) within the camera unit.” See Resp.
11
United States District Court
Northern District of California
10
Br. at 4–5.
12
13
14
As Samsung notes, the Federal Circuit has already construed this term, albeit in the context
of claim 73:
16
The specification thus clearly links two structures to the claimed
means for performing the function of processing and storing image
information obtained by the camera for later recall: “microprocessor
23” and “memory unit 24,” the processor and memory units within
the camera unit.
17
See MMI, 780 F.3d at 1170. And Ironworks does not dispute this construction. See Reply Br. at 3
18
n.1. Instead, Ironworks argues that claims 1 and 73 use the term differently, and that adopting
19
Samsung’s construction would render redundant claim 1’s inclusion of a separate “memory unit.”
20
See Resp. Br. at 16. But the Court is unpersuaded that Samsung’s recitation of “memory unit 24”
21
as structure would render redundant the claim’s requirement of “at least one memory unit for
22
storing said image information”: memory unit 24 could conceivably represent the “memory unit
23
for storing said image information.” Moreover, the Federal Circuit relied on the specification
24
generally—including column 4:23–31 and the block diagram in Figure 5—to locate corresponding
25
structure for this term. See MMI, 780 F.3d at 1168–71 (“The specification explains that the
26
structure of the camera unit ‘conforms to the block diagram shown in Fig. 5.’”). Ironworks does
27
not explain why claim 1’s recitation of the “memory unit” would alter the Federal Circuit’s
28
recitation of structure from the specification.
15
12
1
The Federal Circuit rejected a similar argument in Laitram Corp. v. Rexnord, Inc., 939
2
F.2d 1533 (Fed. Cir. 1991). There, the plaintiff argued that the court should not include a
3
structural limitation in its interpretation of a means-plus-function term, because doing so would
4
render redundant a dependent claim that recited that limitation. See id. at 1538. The Federal
5
Circuit disagreed, finding that the interpretation of the disputed term came from the specification,
6
and not from the dependent claim. Id. In turn, the court found that it could include the limitation
7
while avoiding the prohibition against improperly reading limitations into an independent claim
8
from a dependent one. Id. The court stressed that the related doctrine of “claim differentiation,”
9
which instructs that different claims typically have different meanings, is a “guide, not a rigid
rule.” Id. (quoting Autogiro Co. of Am. v. United States, 384 F.2d 391, 404 (Ct. Cl. 1967)). The
11
United States District Court
Northern District of California
10
Court continued:
12
Simply stated, the judicially developed guide to claim interpretation
known as “claim differentiation” cannot override the statute. A
means-plus-function limitation is not made open-ended by the
presence of another claim specifically claiming the disclosed
structure which underlies the means clause or an equivalent of that
structure. If Laitram’s argument were adopted, it would provide a
convenient way of avoiding the express mandate of section 112(6).
We hold that one cannot escape that mandate by merely adding a
claim or claims specifically reciting such structure or structures.
13
14
15
16
17
18
Id. As in Laitram, adopting the Federal Circuit’s identified structure would not run afoul of the
19
claim differentiation doctrine.
20
Separately, Ironworks notes that Samsung’s construction differs from the Federal Circuit’s
21
in that Samsung omits the word “unit” after memory. At the claim construction hearing, however,
22
Samsung said it did not object to the inclusion of “unit.” Dkt. No. 157 at 25:8–13. The Court
23
finds that there is no principled reason for omitting “unit” and thus agrees with its inclusion.

Ironworks again argues that the Court need not construe this term, and asks the Court to

give the term its “plain and ordinary meaning.” Reply Br. at 6. Again, Ironworks failed to
17
provide the Court any such “plain and ordinary meaning,” or explain why the Court should adopt
18
such a construction.
Unlike terms already discussed by the Court, Ironworks only provided an alternative
19
20
construction for this term by way of reply. But as Samsung correctly argues, Ironworks waived
21
any alternative construction argument for this term by omitting it in the opening brief. See Resp.
22
Br. at 11 (citing Trans Video Elecs., Ltd. v. Sony Elecs., Inc., 278 F.R.D. 505, 509 (N.D. Cal.

25

The Court holds that no construction is necessary, but that the plain and ordinary

how the term is used in the claim language. See JCCS, App. A at 3.

proffers a specific plain and ordinary meaning or submits evidence of what a person of ordinary

skill in the art would understand this term to mean.
27
28
At the claim construction hearing, the parties agreed that the Court need only determine
whether the plain and ordinary meaning of this term permits the memory unit to be outside of the
15
1
camera unit. Dkt. No. 157 at 32:7–21. To this end, the Court agrees with Samsung that the claim
2
naturally refers to “at least one memory unit” that is inside the camera unit, lest the phrasing “and
3
having” be written out of the claim. See Resp. Br. at 9 (citing K-2 Corp. v. Salomon S.A., 191

10
This disputed term appears in independent claims 4 and 10 of the ’239 Patent. See JCCS,
12
App. A at 5. The preamble of claim 4 is representative of how the term is used.
13
Claim 4
14
4. A voice controlled device comprising:
means for storing the telephone numbers to be selected,
means for storing at least one identifier for each telephone number to be selected,
means for receiving an identifier given in a voice form,
means for interpreting the received voice commands,
means for selecting a telephone number in response to a voice command,
wherein the identifier comprises a plurality of sub-identifiers, and the voice controlled
device comprises means for storing the sub-identifiers, and means for selecting a telephone
number in response to a voice command comprising at least two of the plurality of subidentifiers including the sub-identifier.
15
16
17
18
19
20
21
22
Samsung argues that construction of the preamble is necessary “to clarify that the devices
23
of claims 4 and 10 include the other means recited in those claims.” See Resp. Br. at 24.
24
Samsung claims that this preamble language limits the “wherein” clauses of claims 4 and 10, each
25
of which uses the “voice controlled device” language from the preamble. Id. at 24–25
26
As Samsung notes, preambles limit claims in certain situations. Id. “[A] preamble limits
27
the invention if it recites essential structure or steps, or if it is ‘necessary to give life, meaning, and
28
vitality’ to the claim.” Catalina Mktg Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed.
16
1
Cir. 2002) (quoting Pitney Bowes, Inc. v. Hewlett-Packard Co., 182 F.3d 1298, 1305 (Fed. Cir.
2
1999)). Preambles are not limiting, however “where a patentee defines a structurally complete
3
invention in the claim body and uses the preamble only to state a purpose or intended use for the
4
invention.” Id. (quoting Rowe v. Dror, 112 F.3d 473, 478 (Fed. Cir. 1997)).
5
No construction of this term is necessary. Although Samsung claims that “voice controlled
6
device” appears elsewhere, and thus limits other claims, Samsung’s proposed construction of the
7
preamble only seeks to construe “comprising,” as meaning “all the means in the remaining claim
8
elements.” See Resp. Br. at 24–25. But, as a matter of law, the term “comprising” has a well-
9
established meaning as “including but not limited to.” See CIAS, Inc. v. All. Gaming Corp., 504
F.3d 1356, 1360 (Fed. Cir. 2007); Georgia-Pacific Corp. v. U.S. Gypsum Co., 195 F.3d 1322,

12
Cir. 1999). Because Samsung only seeks construction of “comprising,” which has a well-
13
established meaning, the Court need not construe this term.

8
The parties’ dispute turns on what structure adequately corresponds to the agreed-upon
10
function of “storing the sub-identifiers.” See Op. Br. at 22. Ironworks argues that Samsung’s
11
United States District Court
Northern District of California
9
construction improperly reads additional limitations into the claim, in part by requiring a specific
12
algorithm as structure for the claimed function. See id. at 22–23. Ironworks contends that this
13
case falls within the “Katz exception,” which allows “a standard microprocessor” to serve as
14
“sufficient structure for ‘functions [that] can be achieved by any general purpose computer
15
without special programming.’” Id. at 23 (quoting In re Katz Interactive Call Processing Patent
16
Litg. (“Katz”), 639 F.3d 1303, 1316 (Fed. Cir. 2011)). Ironworks further argues that the claimed
17
“storing” function here can be performed by a general-purpose computer without special
18
programming. Id. Separately, Ironworks asserts that Samsung’s construction, which requires
19
memory to be “voice pattern memory,” conflicts with the specification’s disclosure of a means to
20
store contact information via “voice-equivalent memory.” Id. at 23–25.
21
Katz “identified a narrow exception to the requirement that an algorithm must be disclosed
22
for a general-purpose computer to satisfy the disclosure requirement.” Ergo Licensing, LLC v.
23
CareFusion 303, Inc., 673 F.3d 1361, 1364–65 (Fed. Cir. 2012); see also Aristocrat Techs. Austl.
24
Pty Ltd. v. Int’l Game Tech., 521 F.3d 1328, 1333 (Fed. Cir.2008) (articulating the default rule
25
that “the structure disclosed in the specification be more than simply a general purpose computer
26
or microprocessor”). In Ergo Licensing, LLC, the Federal Circuit found that the Katz exception
27
applies only in the “rare circumstance[]” where the claimed function “can be achieved by any
28
general purpose computer without special programming.” See id. (quotation omitted) (concluding
18
1
that the function of “controlling the adjusting means” for measuring fluids delivered into a
2
patient’s body “requires more than merely plugging in a general-purpose computer”). The Federal
3
Circuit again cabined Katz in EON Corp. IP Holdings LLC v. AT&T Mobility LLC (“Eon Corp.”),
4
785 F.3d 616 (Fed. Cir. 2015), holding that Katz applies only where “the claimed function is
5
‘coextensive’ with a microprocessor itself.” Id. at 621–22.
6
Both Katz and Eon Corp. recognized that “‘storing’ data” is a function co-extensive with a
7
microprocessor. Accordingly, one component of the agreed-upon function here—“storing”—is
8
analogous to the one discussed in Katz. But the particular function of storing the subidentifiers
9
requires something more than merely “plugging in” a general-purpose computer. See Ergo
Licensing, Inc., 673 F.3d at 1365. To this end, Samsung points to the flow chart in Figure 2 and
11
United States District Court
Northern District of California
10
the specification at column 4:19–37 and 4:51–54. Those lines of the specification state: “In the
12
phase when the user wishes to store the identifier of the telephone number, the voice-control unit
13
2” must be “set to a mode in which the voice-control unit can expect to receive identifiers.” ’239
14
Patent, 4:19–24 (noting that “[t]his function mode is described in the following [lines] with
15
reference to the flow chart of FIG. 2”). Changing over to the store-identifier “function mode” is
16
subsequently accomplished either by “keying the voice-store key A or through the menu facility.”
17
Id. at 4:25–28. “The voice-recognition unit” then creates a message “‘Pronounce the identifier,’”
18
after which the user pronounces the sub-identifiers, e.g. “William,” “Matthew,” or “Herbert.” Id.
19
at 4:28–33. “Each pronounced sub-identifier” is then “stored into the voice-equivalent memory.”
20
Id. at 4:35–36. This step-by-step process articulates a “narrower construction” of the “storing”
21
function sufficient to bring the term outside the Katz exception. See Katz, 639 F.3d at 1316
22
(holding that “[a]bsent a possible narrower construction of the terms ‘processing,’ ‘receiving,’ and
23
‘storing,’ . . . those functions can be achieved by any general purpose computer without special
24
programming”).
25
Several of Ironworks’s own assertions show that the function of “storing” subidentifiers is
26
not coextensive with a general-purpose computer or microprocessor. First, Ironworks’s
27
construction identifies corresponding structure as “memory. . . and programming for storing sub-
28
identifiers in the memory.” See Op. Br. at 22. Ironworks’s assertion that this programming is
19
1
inherent to any computer-implemented function, Reply Br. at 13, is belied by the specification’s
2
specific, narrower construction. Second, Ironworks’s own citations to the specification regarding
3
voice-equivalent memory show that the storing of sub-identifiers requires special consideration of
4
how those identifiers are input—for instance, either through “keying” or “pronouncing” the
5
identifier and telephone number. See Reply Br. at 14–15. Indeed, the specification at column 4:7–
6
15 states:
7
Also the numerals from zero to nine are advantageously stored into
the voice-equivalent memory, wherein the user can store also the
telephone number by pronouncing it, wherein the voice-control unit
2 transforms the pronounced telephone number preferably to signals
corresponding to the numeral keys and stores the information on the
telephone number to the telephone number memory, wherefrom it
can be collected when calling. The user can give the telephone
number also by keying in the corresponding numerals.

United States District Court
Northern District of California
11
Although the Court agrees with Samsung’s proposed structure, it finds that there is no
12
13
principled reason for omitting, and thus includes, the language at column 4:38–50 of the
14
specification.6
With respect to “voice-equivalent” and “voice pattern” memory, Ironworks is correct that
15
16
the specification indicates that an identifier can be stored in either form of memory. See Reply Br.
17
at 14–15. The specification appears to use the terms interchangeably. See ’239 Patent, 3:65–4:3
18
(“According to the pronounced command, the voice-recognition means 3 forms an identifier,
19
which is stored to the voice pattern memory 4. Prior art includes several alternative
20
implementations for voice-recognition means 3 and voice-equivalent memory 4 and they are
21
known by an expert in the field.”). For that reason, the Court modifies Samsung’s structural
22
construction to include both “voice pattern memory” and “voice-equivalent memory.”

The parties agree that the term is a means-plus-function term, and that the function is
18
19
“interpreting the received voice commands.” Op. Br. at 19; Resp. Br. at 11. The dispute
20
accordingly turns on whether there is sufficient corresponding structure for the term to survive
21
under Section 112. See Op. Br. at 19; 7 Williamson, 792 F.3d at 1351 (holding that a means-plus-
22
function term is indefinite “if a person of ordinary skill in the art would be unable to recognize the
23
structure in the specification and associate it with the corresponding function in the claim”).
24
Samsung argues that such a structure is lacking because the specification fails to recite an
25
algorithm for the agreed-upon function. See Resp. Br. at 12; see also Typhoon Touch Techs., Inc.
26
v. Dell, Inc., 659 F.3d 1376, 1384 (Fed. Cir. 2011) (“The usage ‘algorithm’ in computer systems

According to Ironworks, the associated structure is “voice control unit, voice recognition

12
No. 145-8 (“Valliath Decl.”).
13
The Court finds Ironworks’s arguments unpersuasive. To begin, Ironworks cites no
14
authority to rebut the requirement that the specification must present an algorithm as a name for
15
structure of the claimed function. See Aristocrat Techs. Austl. Pty Ltd., 521 F.3d at 1334; Triton
16
Tech of Tex., LLC v. Nintendo of Am., Inc., 753 F.3d 1375, 1378 (Fed. Cir. 2014) (“Failure to
17
disclose the corresponding algorithm for a computer-implemented means-plus-function term
18
renders the claim indefinite.”). Ironworks does not identify a “step-by-step procedure” for the
19
function of “interpreting the received voice commands.” And the lines of the specification to
20
which Ironworks refers make clear that a “voice-recognition means” is but one component of a
21
broader “voice-control” unit. See ’239 Patent, 3:26–30 (“A voice-control unit 2 comprises
22
advantageously a voice-recognition means 3, a voice pattern memory 4, a controller unit 5, read-
23
only memory 6, random access memory 7, speech synthesizer 8 and a[n] interface 9.”). Figure 1
24
accordingly shows a “SPEECH RECOGN.” box “3” that is located within the voice control unit
25
box, “2.” And while column 5:9–25 could set forth a sufficiently specific step-by-step procedure
26
for the operation of the voice-control unit, Ironworks expressly disclaims that the “voice control
27
unit” is corresponding structure for the “means for interpreting the received voice commands.”
28
Reply Br. at 7 (“First, the proposed structure is not limited to the ‘voice control unit.’”).
22
1
Ironworks’s arguments regarding the prior art likewise miss the mark. Even if voice
2
recognition technology was well-known from the prior art, that does not mean an artisan of
3
ordinary skill would have recognized an algorithm as structure from the specification. Rejecting
4
an analogous argument in Triton Tech, the Federal Circuit explained:

9
The fact that various numerical integration algorithms may have
been known to one of ordinary skill in the art does not rescue the
claims. A bare statement that known techniques or methods can be
used does not disclose structure. The district court correctly
recognized that although a person of skill in the art might be able to
choose an appropriate numerical integration algorithm and program
it onto a microprocessor, the patent discloses no algorithm at all.’
753 F.3d at 1379 (quotations and citations omitted). Ironworks admits in its reply that its expert
11
United States District Court
Northern District of California
10
entirely skips over the fundamental inquiry of whether there is an algorithm for structure. See
12
Reply Br. at 9 (“Valliath does not use the word ‘algorithm’ because Samsung never before raised
13
that specific argument.”). Indeed, Valliath speaks primarily to whether the “the means for
14
interpreting voice commands was already well known in the art” at the time of the invention. See
15
Valliath Decl. ¶¶ 21–24. Valliath’s identification of structure suffers from the same flaws as
16
Ironworks’s construction: Valliath relies on identical lines from the specification. See id. ¶¶ 28–
17
29 (“In the specific context of words used in the ’239 patent and its Figures, one of ordinary skill
18
in the art would have understood that the ’239 patent discloses a structure of the voice control unit,
19
voice recognition circuitry, a controller, RAM, ROM and associated programming, (and
20
equivalents) [for interpreting the received voice commands].”).
21
Although Ironworks omits the argument from its opening brief, it asserts in its reply that
22
the specification does disclose an algorithm. See Reply Br. at 9 (citing ’239 Patent, 5:9–25; 6:1–
23
57). Even if the Court were to consider this argument, it fails. As discussed, column 5:9–25 sets
24
forth a step-by-step process corresponding to the “voice control unit 2.” So too with column 6:1–
25
57. These lines describe how the “voice-control unit 2 defines probability to all the sub-identifier
26
compositions,” and reaches the “final result of the [voice] recognition.” ’239 patent, 6:8–11.
27
These lines likely adequately describe structure corresponding to the “voice control unit 2.” But
28
by Ironworks’s own admission, the “voice control unit” is not equivalent to the “means for
23
1
interpreting the received voice commands.” While Ironworks asserts that algorithms can be
2
designed to accomplish more than one function, see Reply Br. at 10, the lines cited by Ironworks
3
are entirely silent as to the “voice-recognition means 3,” or the term at issue here: “a means for
4
interpreting the received voice commands.” As a result, the Court finds that the term is indefinite
5
under Section 112.

The first term appears in independent claim 4 of the ’239 Patent, and the second term
appears in independent claim 10 of the ’239 Patent. See JCCS, App. A. at 6–8. Claim 4 is

United States District Court

The parties dispute both the claimed function and its corresponding structure. Ironworks’s
12
functional construction parallels the language of the term itself—i.e. “selecting a telephone
13
number in response to a voice command comprising at least two of the plurality of sub-identifiers /
14
a combination of several subidentifiers.” See Op. Br. at 24. Ironworks argues that Samsung’s
15
identification of function improperly imports into the claim embodiments referenced during
16
reexamination of this patent. See Op. Br. at 25–26. As for the corresponding structure, Ironworks
17
identifies the same structure that it identified for the above-discussed term “means for interpreting
18
the received voice commands.” Id. at 27. Ironworks cites the same lines of the specification—
19
Figure 1 and column 3:24–30—as showing structure for this term. Id. at 27. And Ironworks
20
argues that an algorithm is not required because “the ’239 patent specifically discloses a structure
21
that is not limited to a general purpose computer or microprocessor.” Id.
22
In support of its construction of function, Samsung relies primarily on the doctrine of
23
prosecution disclaimer. Specifically, Samsung argues that MobileMedia—the entity that assigned
24
the patent to Ironworks after patent prosecution was complete—repeatedly asserted that the
25
claimed means of performing the function of “selecting a telephone number in response to a voice
26
command” was limited to the “three defining characteristics” that its construction sets forth: that
27
“(1) the sub-identifiers need not be pronounced in the voice command in the order they appear in
28
the identifier; (2) the voice command may include fewer than all of the sub-identifiers in the
25
1
identifier; and (3) additional words that do not match any of the stored sub-identifiers may be
2
pronounced in the voice command, but are ignored.” See Resp. Br. at 17–18. Samsung contends
3
as to structure that an algorithm is required, and that such an algorithm is stated by “two iterative
4
probability-based algorithms at 4:55–5:22, 6:7–11 and 6:40–57.” Id. at 19.
5
Turning first to function, the Court is not persuaded by Samsung’s prosecution disclaimer
6
arguments. The statements upon which Samsung relies for its functional limitations recite “three
7
advantages not found in the prior art.” See Dkt. No. 151-5 at 27–28. This does not rise to the
8
level of disavowal required to evoke the doctrine. See, e.g., Thorner, 669 F.3d at 1366. And
9
although Samsung might be correct that the Federal Circuit does not require “explicit redefinition
or disavowal,” it typically relies on clear guidance in the specification or prosecution history
11
United States District Court
Northern District of California
10
before reading limitations into claims. See Trustees of Columbia Univ. in City of N.Y. v. Symantec
12
Corp., 811 F.3d 1359, 1363 (Fed. Cir. 2016); Aventis Pharma S.A. v. Hospira, Inc., 675 F.3d
13
1324, 1330 (Fed. Cir. 2012) (requiring “clear limiting descriptions of the invention in the
14
specification or prosecution history”); Omega Eng’g, Inc. v. Raytek Corp., 334 F.3d 1314 (Fed.
15
Cir. 2003) (“But where the patentee has unequivocally disavowed a certain meaning to obtain his
16
patent, the doctrine of prosecution disclaimer attaches and narrows the ordinary meaning of the
17
claim congruent with the scope of the surrender.”). Samsung here cites no such clear guidance to
18
support reading in the three specific limitations included in its functional construction.
19
Samsung also points to a statement of MobileMedia that the “sub-identifiers must be stored
20
in the device so as to be usable separately in the selection of the associated telephone number.”
21
See Resp. Br. at 18. But Samsung’s three functional limitations are silent as to storage. Nor does
22
Ironworks’s construction speak to how sub-identifiers are stored. Samsung thus has not shown
23
that Ironworks is estopped from advocating this functional interpretation, and the Court thus
24
adopts Ironworks’s broader construction of function.
25
As to structure, Section 112 requires an algorithm because the claimed function is not co-
26
extensive with a general-purpose computer or microprocessor. See Ergo Licensing, 673 F.3d at
27
1364–65. In its reply, Ironworks only disputes that an algorithm is required—it does not expressly
28
respond to Samsung’s identification of an algorithm in columns 4:55–5:22, 6:7–11 and 6:40–57.
26
1
See Reply Br. at 11–12. The lines of the specification cited by Samsung provide a step-by-step
2
process for a “means for selecting a telephone number in response to a voice command
3
comprising. . .” That is corresponding structure sufficient under Aristrocrat Techs. and

Even if an algorithm were not required, it is not clear how the “voice control unit, voice

equivalents thereof” adequately describes corresponding structure for this claimed function. That
is especially so considering (1) Ironworks cites this same exact structure as performing the abovediscussed “means for interpreting the received voice commands;” and (2) Ironworks relies on
virtually identical lines from the specification for its structural construction of that term, see, e.g.,
’239 Patent, 3:24–30.
