CLAIM CONSTRUCTION OPINION AND ORDER
I.
BACKGROUND
This lawsuit concerns U.S. Patents 8,441,438 and 8,552,978, each of which teach a
“pointing” device that translates its own movement relative to a first reference frame into
a movement pattern in a display plane of a second, display reference frame. Because the
display plane is chosen to correspond with a particular display device, such as a computer
screen, an associated processor generating a display signal to the display device can then
“move” an indicator (e.g., a computer icon or cursor) on the display according to the movement pattern. ’438 Patent at (57); ’978 Patent at (57).
This general concept predates the asserted patents. See, e.g., ’438 Patent at 2:38–47
(referencing prior art). The patents, however, specifically purport to solve a prior-art problem of inaccurately calculating the change in angular velocities and accelerations of the
1 / 18
device when subjected to unexpected movements, particularly in a direction parallel to the
force of gravity. See id. at 2:55–3:5. The patents also criticize the prior art for outputting
only a two-dimensional movement pattern. See id. at 2:47–55 (“the pointing device of Liberty cannot output deviation angles readily in [a] 3D reference frame but rather a 2D reference frame only and the output of such device having 5-axis motion sensors is a planar
pattern in [a] 2D reference frame only”).
To address these shortcomings, the ’438 Patent teaches (1) use of various sensors to
measure angular velocities and axial accelerations along three reference axes of the device,
and (2) predicting the axial accelerations along three reference axes from the measured
angular velocities. The claimed device uses the measured angular velocities, measured axial accelerations, and predicted axial accelerations to calculate a deviation of the yaw, pitch,
and roll angles of the device over time. The claimed device then translates that deviation
into a movement pattern within the display reference frame. See generally ’438 Patent at
7:56–9:5.
The ’978 Patent, which is a continuation-in-part of the ’438 Patent, adds magnetism
to the methodology. Specifically, a magnetometer measures magnetism associated with
three reference axes of the first reference frame. The ’978 Patent also teaches predicting
the magnetism associated with each of the three axes and using both the measured and
predicted magnetisms—along with the measured angular velocities, measured axial accelerations, and predicted axial accelerations already contemplated by the ’438 Patent—to
2 / 18
determine deviation of the yaw, pitch, and roll and translate the resultant angles to a movement pattern in a display reference frame. See generally ’978 Patent at 22:9–23:8; see also,
e.g., id. fig.8 items 745, 750, fig. 11 items 1160, 1165.
II.
GENERAL LEGAL STANDARDS
A.
Claim Construction
“[T]he claims of a patent define the invention to which the patentee is entitled the
right to exclude.” Phillips v. AWH Corp., 415 F.3d 1303, 1312 (Fed. Cir. 2005) (en banc).
As such, if the parties dispute the scope of the claims, the court must determine their meaning. See, e.g., Markman v. Westview Instruments, Inc., 517 U.S. 370, 390 (1996), aff’g, 52
F.3d 967, 976 (Fed. Cir. 1995) (en banc); Verizon Servs. Corp. v. Vonage Holdings Corp.,
503 F.3d 1295, 1317 (Fed. Cir. 2007).
When construing claims, “[t]here is a heavy presumption that claim terms are to be
given their ordinary and customary meaning.” Aventis Pharm. Inc. v. Amino Chems. Ltd.,
715 F.3d 1363, 1373 (Fed. Cir. 2013) (citing Phillips, 415 F.3d at 1312–13). Courts must
therefore “look to the words of the claims themselves . . . to define the scope of the patented
invention.” Id. (citations omitted). The “ordinary and customary meaning of a claim term
is the meaning that the term would have to a person of ordinary skill in the art in question
at the time of the invention, i.e., as of the effective filing date of the patent application.”
Phillips, 415 F.3d at 1313. This “person of ordinary skill in the art is deemed to read the
claim term not only in the context of the particular claim in which the disputed term appears, but in the context of the entire patent, including the specification.” Id.
3 / 18
Intrinsic evidence is the primary resource for claim construction. See Power-One,
Inc. v. Artesyn Techs., Inc., 599 F.3d 1343, 1348 (Fed. Cir. 2010) (citing Phillips, 415 F.3d
at 1312). For certain claim terms, “the ordinary meaning of claim language as understood
by a person of skill in the art may be readily apparent even to lay judges, and claim construction in such cases involves little more than the application of the widely accepted
meaning of commonly understood words.” Phillips, 415 F.3d at 1314. But for claim terms
with less-apparent meanings, courts consider “those sources available to the public that
show what a person of skill in the art would have understood disputed claim language to
mean . . . [including] the words of the claims themselves, the remainder of the specification, the prosecution history, and extrinsic evidence concerning relevant scientific principles, the meaning of technical terms, and the state of the art.” Id.
B.
Indefiniteness
“A patent’s specification must ‘conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as [the] invention.’” Teva Pharm. USA, Inc. v. Sandoz, Inc., 789 F.3d 1335, 1340 (Fed. Cir. 2015)
(quoting 35 U.S.C. § 112 (pre-AIA), ¶ 2). “A patent is indefinite ‘if its claims, read in light
of the specification delineating the patent, and the prosecution history, fail to inform, with
reasonable certainty, those skilled in the art about the scope of the invention.’” Id. (quoting
Nautilus, Inc. v. Biosig Instruments, Inc., 134 S. Ct. 2120, 2124 (2014)). “The definiteness
requirement must take into account the inherent limitations of language.” Id. Thus, “[s]ome
4 / 18
modicum of uncertainty . . . is the ‘price of ensuring the appropriate incentives for innovation.’” Nautilus, Inc., 134 S. Ct. at 2128 (quoting Festo Corp. v. Shoketsu Kinzoku Kogyo
Kabushiki Co., 535 U.S. 722, 732 (2002)). Nonetheless, “a patent must be precise enough
to afford clear notice of what is claimed, thereby appris[ing] the public of what is still open
to them.” Id. at 2129 (internal quotation marks and citations omitted).
Indefiniteness is a question of law that is reviewed de novo. Teva Pharm. USA, Inc.,
789 F.3d at 1341. It must be proven by clear and convincing evidence. Halliburton Energy
Servs., Inc. v. M-I, LLC, 514 F.3d 1244, 1249–50 (Fed. Cir. 2008).

IV.
DISCUSSION—A PERSON OF ORDINARY SKILL IN THE ART
The parties provide similar definitions of a person of ordinary skill in the relevant
art (POSA). According to CyWee, a POSA “at the time of the filing of the [asserted] patents
would typically have at least a Bachelor’s Degree in Computer Science, Electrical Engineering, Mechanical Engineering, or Physics, or equivalent work experience, along with
knowledge of sensors (such as accelerometers, gyroscopes, and magnetometers), and mobile computing technologies.” LaViola Decl. (Feb. 23, 2018) [Dkt. # 66-6] ¶ 11. According
6 / 18
to Defendant, a POSA had “a computer science, electrical engineering, mechanical engineering, or other related technical degree at the undergraduate level, and knowledge of
sensor systems[, although] [s]uperior experience in one of these areas could compensate
for lesser experience in the other.” Mercer Decl. (Mar. 9, 2018) [Dkt. # 67-1] ¶ 40.
Neither party, however, specifically argues that the difference in proffered constructions or indefiniteness positions is attributable to the difference, if any, between these levels
of ordinary skill. Accordingly, the Court considers the difference in proffered levels of skill
immaterial to its analysis.
V.
DISCUSSION—CONSTRUCTION OF DISPUTED TERMS
A.
“3D pointing device” (’438 Patent, claims 1, 3–5, 14–17, 19; ’978 Patent,
claim 10)
CyWee’s
Proposed Construction
Defendants’
Proposed Construction
Not necessary. Alternatively, “a handheld
device that includes at least one or more accelerometers and a magnetometer, and optionally a rotation sensor comprising one or
more gyroscopes, and uses them to determine deviation angles or the orientation of
a device.”
a device that detects the motion of the device in three dimensions and translates the
detected motions to control the movement
of a cursor or pointer on a display
CyWee argues this term does not require construction, but nonetheless proposes an
alternative construction that adds accelerometers, magnetometers, and gyroscopes. Pl.’s Br.
[Dkt. # 66] at 13–17. Defendants contend this term requires the device to control the move-
7 / 18
ment of a cursor or pointer on a display. Defs.’ Br. [Dkt. # 67] at 17–22. Such a construction, say Defendants, is proper because it conforms to the patents’ usage of the term in the
specifications and because it is consistent with every embodiment disclosed in the patents.
Id. at 18–19. Moreover, this construction is supported by the relevant extrinsic evidence.
Id. at 20–22.
A court normally has no obligation to provide a special definition for terms, like this
one, that have a widely understood ordinary meaning, as long as the court is persuaded that
the patent uses the terms in the ordinary sense. See Phillips, 415 F.3d at 1314 (“[T]he ordinary meaning of claim language as understood by a person of skill in the art may be
readily apparent even to lay judges, and claim construction in such cases involves little
more than the application of the widely accepted meaning of commonly understood
words.”); see also Eon Corp. IP Holdings v. Silver Springs Networks, 815 F.3d 1314, 1329
(Fed. Cir. 2016) (Bryson, C.J., dissenting) (“[T]here is ordinarily no obligation to provide
a special definition for terms that have a widely understood ordinary meaning, as long as
the court is persuaded that the patent uses the terms in that ordinary sense.”). Here, each of
the phrase’s constituent parts has a widely understood ordinary meaning consistent with
their usage in the patent, which is evidenced by Defendants’ use of two of the terms in their
proposed construction. And considering the phrase as whole does not impart any different
meaning to those terms, Defendants’ proposed construction is unnecessary and this term
requires no special definition.
8 / 18
B.
“six-axis motion sensor” / “six-axis motion sensor module” (’438 Patent,
claims 1, 5, 14–17, and 19)
CyWee’s
Proposed Construction
Defendants’
Proposed Construction
Not necessary. Alternatively, “a collection
of components comprising a rotation sensor
comprising one or more gyroscopes for cola module consisting of two types of senlectively generating three angular velocisors: (i) a rotation sensor and (ii) one or
ties and one or more accelerators for collecmore accelerometers
tively generating three axial accelerations
where said gyroscopes and accelerometer(s) are mounted on a common PCB”
Defendants contend the patentee limited the scope of this term in two ways. First,
Defendants argue the patentee defined “six-axis” to mean “the three angular velocities wx,
wy, wz and the three axial accelerations Ax, Ay, Az.” Defs.’ Br. [Dkt. # 67] at 23 (citing
’438 Patent at 8:10–12). Second, Defendants contend the patentee disavowed claim scope
by arguing, in response to a double-patenting rejection, the ’438 Patent “includes the
claimed subject matter of a six-axis motion sensor module without having and using measured magnetisms and predicted magnetisms.” Defs.’ Br. [Dkt. # 67] at 23–24. (citing Apr.
17, 2013 Amendments [Dkt. # 67-13] at 10).
Defendants’ “lexicography” argument is not persuasive. Although the patent defines
“six-axis,” it does not define “six-axis module” or “six-axis sensor” as limited to a device
that only measures three angular velocities and three axial accelerations. Rather, the patent
simply uses “six-axis” to refer to the relevant axes of the invention, and nothing in the
patent suggests “six-axis” cannot mean “at least six axes.” As such, the patent does not so
9 / 18
clearly redefine the term so as to justify Defendants’ proposed construction. See Hill-Rom
Servs., Inc. v. Stryker Corp., 755 F.3d 1367, 1371 (Fed. Cir. 2014) (“The standards for
finding lexicography . . . are exacting. ‘To act as its own lexicographer, a patentee must
clearly set forth a definition of the disputed claim term other than its plain and ordinary
meaning’ and must ‘clearly express an intent to redefine the term.’” (quoting Thorner v.
Sony Comput. Entm’t Am., LLC, 669 F.3d 1362, 1365 (Fed. Cir. 2012)).
Nor is Defendants’ “disavowal” argument persuasive. In the amendments, the patentee simply pointed the examiner to one difference between the patent’s claims and those
of the pending application to overcome a double patenting rejection. That is not the “clear
and unmistakable disavowal” required to narrow the meaning of claim language. See HillRom Servs., Inc., 755 F.3d at 1372 (noting disavowal requires the prosecution history to
clearly indicate the invention excludes a particular feature or limits the invention to a particular form); Albany Molecular Research, Inc. v. Dr. Reddy’s Labs., Ltd., No. 09-4638
(GEB-MCA), 2010 WL 2516465, at *4 (D.N.J. June 14, 2010) (concluding that pointing
the examiner to one difference in the claims to overcome a double patenting rejection is
not “clear disavowal” of claim scope).
Having rejected Defendants’ proposed construction, no further construction is necessary.
10 / 18
C.
“global reference frame associated with the Earth” (’978 Patent, claim
10)
CyWee’s
Proposed Construction
Defendants’
Proposed Construction
Not necessary. Alternatively, “reference an Earth-centered coordinate system with
frame with axes defined with respect to an origin and a set of three coordinate axes
defined with respect to Earth
Earth”
The parties agree this term requires axes defined with the respect to the Earth, but
dispute (1) whether the frame requires three axis, and (2) whether the term requires the
origin of the reference frame to be near the Earth’s center. CyWee argues “global reference
frame” is a commonly used term of art that refers to a fixed frame. Pl.’s Br. [Dkt. # 66] at
26–27 (citing LaViola Decl. ¶ 30). Relying solely on extrinsic evidence, Defendants contend the term requires a reference frame with an origin at the Earth’s center of mass. Defs.’
Br. [Dkt. # 67] at 26–27.
The Court rejects Defendants’ proposed construction for three reasons. First, there’s
no need to construe the term as having a set of three coordinate axes, as that requirement
is already recited in the claim. ’978 Patent at 36:65–67 (reciting a device “associated with
three coordinate axes of a global reference frame associated with Earth”). That suggests
the reference frame may have more than three axes. See Primos, Inc. v. Hunter’s Specialties, Inc., 451 F.3d 841, 847 (Fed. Cir. 2006) (noting that when the claims use separate
terms, “each term is presumed to have a distinct meaning”). Second, nothing in the intrinsic
evidence requires the “global reference frame” to have an origin at Earth’s center.
Finally, there’s no technical reason why the claimed invention would require any
11 / 18
reference frame to have a specific origin given the ease with which a point in one frame
can be mapped to another frame. Indeed, the ’978 Patent’s use of “frame associated with”
throughout the specification shows the location of the reference frame’s origin is not important. In addition to a “global reference frame associated with the Earth,” the patent refers
to a “spatial pointer reference frame associated with the pointing device,” id. at 1:42–43,
and “a display reference frame associated with [a] display,” id. at 13:14–15. But the specification does not show or describe these reference frames as having an origin at the center
of the associated structure. See, e.g., ’978 Patent fig.1 (showing the display frame as having
an origin that does not intersect the 2D display device 120 and screen 122); supra at 6–7
(reciting the parties’ agreed construction for “spatial reference frame,” which only requires
the origin of the reference frame be “at the same point in the device” and “always fixed
with respect to the device”). The patent provides no reason to think “global reference frame
associated with the Earth” should be interpreted more stringently. Accordingly, the Court
construes the term as “reference frame with axes defined with respect to the Earth.”
D.
“using the orientation output and the rotation output to generate a
transformed output associated with a fixed reference frame associated
with a display device” (’978 Patent, claim 10)
CyWee’s
Proposed Construction
Defendants’
Proposed Construction
using the orientation output and the rotation output to generate a transformed output represented by a 2-dimensional movement in a fixed reference frame that is parallel to the screen of a display device
using the orientation output and rotation
output to generate a transformed output
representing a two-dimensional movement
in a fixed reference frame that is parallel to
the screen of the display device
12 / 18
The parties propose similar constructions, but dispute whether (1) the transformed
output represents two-dimensional movement, or (2) the two-dimensional movement represents the transformed output. CyWee argues that Defendants’ construction limits the
transformed output to representing only two-dimensional movement. Pl.’s Br. [Dkt. # 66]
at 28. Defendants contend the specification clearly reflects that the “transformed output”
is a two-dimensional vector representing two-dimensional movement. Defs.’ Br. [Dkt.
# 67] at 25.
Contrary to CyWee’s position, the patent indicates the transformed output represents
movement—not the other way around. In fact, Defendants’ proposed construction is taken
almost verbatim from the specification. See ’978 Patent at 31:51–32:3 (“The transformed
output . . . represents a 2-dimensional movement in a display plane in the fixed reference
frame.”). Nonetheless, there’s no reason the claim scope should be limited to representing
only two-dimensional movement given that the passage on which Defendants rely only
relates to a particular embodiment. See Liebel-Flarsheim Co. v. Medrad, Inc., 358 F.3d 898,
904 (Fed. Cir. 2004) (“Even when the specification describes only a single embodiment,
the claims of the patent will not be read restrictively unless the patentee has demonstrated
a clear intention to limit the claim scope using ‘words or expressions of manifest exclusion
or restriction.” (quoting Teleflex, Inc. v. Ficosa N. Am. Corp., 299 F.3d 1313, 1327 (Fed.
Cir. 2002)). In fact, the specification contemplates that a 2D reference frame may be just
one type of possible display reference frame. See ’978 Patent at 12:48–58 (referring to
mapping the calculated deviation “to a display reference frame such as a 2D reference
13 / 18
frame”). Accordingly, the Court construes the term as “using the orientation output and
rotation output to generate a transformed output representing a movement in a fixed reference frame that is parallel to the screen of the display device.”
VI.
DISCUSSION—INDEFINITENESS
Defendants challenge a number of claims terms as indefinite:
•
utilizing a comparison to compare the first signal set with the second signal
set (’438 Patent, cl.1);
•
comparing the second quaternion in relation to the measured angular velocities ωx, ωy, ωz of the current state at current time T with the measured axial
accelerations Ax, Ay, Az and the predicted axial accelerations Ax’, Ay’, Az’
also at current time T (’438 Patent, cl.14, 19); and
•
generating the orientation output based on the first signal set, the second signal set and the rotation output or based on the first signal set and the second
signal set (’978 Patent, cl.10).
These phrases, say Defendants, render the associated claims indefinite for three reasons. First, the “second signal set” includes axial accelerations, and a POSA would recognize an “axial acceleration” could be any one or more of (a) linear accelerations, (b) centrifugal accelerations, and (c) gravitational accelerations. Thus, a POSA would not know
how to compare the first signal set of angular velocities with the second signal set of axial
accelerations. Second, a POSA could not “decompose” the acceleration reading measured
by an accelerometer into separate linear, rotational, and gravitational components because
accelerometers do not contain information regarding the source or type of force underlying
14 / 18
the measured acceleration. Finally, Defendants claim a mathematically meaningful comparison between angular velocities and axial accelerations is impossible.
A.
Axial Accelerations
The patent is clear that “axial accelerations” refers to the acceleration vectors along
three axes of the associated reference frame. Thus, regardless of whether the pointing device is undergoing linear, centrifugal, and/or gravitational acceleration, at any instant the
acceleration of the device can be represented by vectors along axes of the chosen reference
frame. In other words, while the type of acceleration may affect the magnitudes and rates
of change of the vectors, the total acceleration can nonetheless be represented by axial
accelerations Ax, Ay, and Az in the associated reference frame at any instant. The asserted
patents are therefore not indefinite on this basis.
B.
Decomposing the Acceleration Reading by an Accelerometer
Defendants next argue that a POSA could not “decompose” the acceleration reading
measured by an accelerometer into separate linear, rotational, and gravitational components, because accelerometers do not contain information regarding the source or type of
force underlying the measured acceleration. This, however, is not an indefiniteness argument, but an argument directed to inoperability or lack of enablement. See EMI Group
North America, Inc. v. Cypress Semiconductor Corp., 268 F.3d 1342, 1348 (Fed. Cir. 2001)
(“A claimed invention having an inoperable or impossible claim limitation may lack utility
under 35 U.S.C. § 101 and certainly lacks an enabling disclosure under 35 U.S.C. § 112.”).
The Court therefore declines to address the merits of this argument in the context of claim
15 / 18
construction. The claims are not rendered indefinite on this ground.
C.
A Mathematically Meaningful Comparison
Finally, Defendants claim a meaningful comparison between angular velocities and
axial accelerations is “mathematically impossible.” If “axial acceleration” means either
linear or gravitational acceleration, Defendants contend those types of accelerations cannot
be compared with angular velocity. Defs.’ Br. [Dkt. # 67] at 5–6. If, however, “axial acceleration” refers to centrifugal acceleration, Defendants say a POSA would require more
data. Id. at 6 (relying on Invensys Sys., Inc. v. Emerson Elec. Co., No 6:12-cv-799, 2014
WL 3976371 (E.D. Tex. Aug. 6, 2014)).
CyWee counters with two arguments. First, CyWee notes this argument was rejected
in other proceedings involving the same patent. Pl.’s Br. [Dkt. # 66] at 8–9 (citing Cywee
Group Ltd. v. Apple Inc., No. 14-cv-01853-HSG, 2015 WL 5258728, at *4 (N.D. Cal. Sept.
9, 2015), in which the court concluded the defendant’s position was overly rigid and that
the specification adequately describes how deviation angles can be used to compare the
signal sets). Second, rather than a direct comparison between measurements with different
dimensions, the patent defines “comparison” as “the calculating and obtaining of the actual
deviation angles of the 3D pointing device.” Id. at 9. CyWee argues the patent discloses an
extended Kalman filter that allows the comparison between angular velocities and axial
accelerations. Id.
The primary case on which Defendants rely, Invensys Systems, is distinguishable.
There, the disputed claim language recited a specific algebraic operation: calculating a dot
16 / 18
product of (1) a normalized pulsation and (2) a series of sensor signals. Invensys Sys., Inc.,
2014 WL 3976371, at *4–5. The patent limited the “normalized pulsation” to one number,
yet the dot-product operation requires two equal-length series of numbers. Id. at *5. Because the sensor signals were series (i.e., more than a single number), the court concluded
the claim language required a mathematically impossible step because it was not performable as claimed. Id.
The present facts are distinguishable from Invensys. Here, the disputed claim language does not recite a precise mathematical operation, but rather the “comparison” of two
signal sets with different measurements. The patents acknowledge the methodology does
not invoke a precise apples-to-apples comparison and requires some conversion. See, e.g.,
’438 Patent at 12:39–60 (providing “a data conversion utility to convert the angular velocities ωx, ωy, and ωz into the second quaternion”); id. at 13:32–37 (noting “it is preferable to
compare the second quaternion . . . with the measured axial accelerations Ax, Ay, Az”).
Compare Cywee Group Ltd., 2015 WL 5258728, at *4 (“The specification also describes
how those deviation angles may be used to compare the signal sets—for example, through
the use of quaternions.”). For this invention, that’s sufficient to be “meaningful.”
For these reasons, the Court finds the specification sufficiently informs a person
having ordinary skill how to compare the signal sets with reasonable certainty. Defendants,
therefore, have not shown these claims are indefinite by clear and convincing evidence.
VII.
