REPORT AND RECOMMENDATION
On January 17, 2014, Defendants Microsoft Corporation, Electronic Arts, Inc. ("EA"),
and Ubisoft, Inc. ("Ubisoft") (collectively, "Defendants") filed a Motion for Partial Summary
Judgment ofNoninfringement and No Willful Infringement ("Motion for Summary Judgment of
Noninfringement" or "Motion") as to United States Patent Nos. 6,308,565 (the '"565 patent"),
6,765,726 (the "'726 patent"), 6,876,496 (the '"496 patent"), 7,359,121 (the '"121 patent"),
7,791,808 (the "'808 patent"), and 6,430,997 (the '"997 patent"). (D.1. 332; D.I. 333 at 1-4) On
March 27, 2015, the Court issued a Report and Recommendation regarding that Motion,
recommending that the District Court grant summary judgment of non-infringement in
Defendants' favor as to 14of15 asserted claims in the case. (D.I. 409) Remaining to be
resolved is Defendant Ubisoft's argument that summary judgment should be granted to it on the
ground that it does not infringe the remaining asserted claim in the case: claim 11 of the '997
patent. (D.1. 333 at 37-38; D.I. 410) The instant Report and Recommendation addresses that
issue, as well as Ubisoft's assertion that summary judgment should be granted in its favor on the
ground that any infringement of claim 11 of the '997 patent was not willful as a matter of law.

(D.I. 333 at 38-40) The Court recommends that the Motion be DENIED as to non-infringement
of claim 11 of the '997 patent by Ubisoft, but that it be GRANTED as to no willful infringement
regarding claim 11.

I.

BACKGROUND
The Court incorporates by reference the factual background set forth in its prior Report

and Recommendation. (D.I. 409 at 2-4) To the extent further facts of record are relevant to the
instant Report and Recommendation, they are otherwise set forth herein.

II.

STANDARD OF REVIEW
In reviewing the Motion as it relates to these remaining issues, the Court utilizes the

familiar summary judgment standards set forth in Federal Rule of Civil Procedure 56 and in the
jurisprudence of the Supreme Court of the United States. Those standards were described in the
Court's prior Report and Recommendation, (id. at 4-6), and the Court applies them again to the
issues raised below.

III.

DISCUSSION
A.

Non-infringement of Claim 11 of the '997 Patent
1.

Legal Standard Regarding Infringement

The standard for patent infringement is set forth in 35 U.S.C. § 271, which states that
"whoever without authority makes, uses, offers to sell, or sells any patented invention, within the
United States or imports into the United States any patented invention during the term of the
patent therefor, infringes the patent." An infringement analysis is performed on a claim-by-claim
basis. Amazon.com, Inc. v. Barnesandnoble.com, Inc., 239 F.3d 1343, 1351 (Fed. Cir. 2001).
In order to prove infringement, "the patentee must show that an accused product embodies all

2

limitations of the claim either literally or by the doctrine of equivalents." Cephalon, Inc. v.

Watson Pharm., Inc., 707 F.3d 1330, 1340 (Fed. Cir. 2013).
To literally infringe the claim, an accused device must embody each limitation of the
claim; the absence of any limitation defeats literal infringement. Research Plastics, Inc. v. Fed

Packaging Corp., 421 F.3d 1290, 1297 (Fed. Cir. 2005). To prove infringement under the
doctrine of equivalents, "a patentee must provide particularized testimony and linking argument
with respect to the 'function, way, result' test." Cephalon, 707 F.3d at 1340 (noting that the
essential inquiry in any such determination is whether "the accused product or process contain[ s]
elements identical or equivalent to each claimed element of the patented invention") (internal
quotation marks and citation omitted). The function-way-result test "asks whether an element of
an accused product performs substantially the same function in substantially the same way to
obtain the same result as an element of the patented invention." Id (internal quotation marks and
citation omitted). 1

2.

Discussion

Ubisoft's non-infringement argument here focuses on the claim term "training sequence"
used in claims 5 and 11 of the '997 patent. (D.I. 333 at 37-38) The term appears in independent
claim 5 (to which claim 11 depends), and together, the two claims read as follows:

In resolving Ubisoft's Motion as to claim 11 below, the Court is required to
construe a claim term. In doing so, the Court turns for guidance to precedent from the Supreme
Court and the United States Court of Appeals for the Federal Circuit regarding claim
construction, previously set out in the Court's May 13, 2013 Report and Recommendation
regarding claim construction. See Impulse Tech. Ltd v. Microsoft Corp., C.A. No. 11-586-RGACJB, 2013 WL 2020055, at *2-4 (D. Del. May 13, 2013).

5. A reactive power training system comprising:
a reactive training device which provides cues to elicit responsive
changes in an overall physical location of a subject in at least
two dimensions; and
a resistive training device;
wherein the reactive training device and the resistive training
device are used in a training sequence.

11. The system of claim 5, wherein the reactive training device
includes positional tracking of the subject in at least two vectors
of movement.

('997 patent, col. 45: 1-7, 31-33 (certain emphasis added)) In its briefing, Ubisoft argued that a
'"training sequence' requires alternation between using a reactive training device and a resistive
training device[.]" (D.1. 333 at 37 (certain emphasis added and omitted)) And, in tum, it
asserted that its accused products (the "Your Shape mini-games") do not involve such
alternation, and therefore cannot meet the "training sequence" claim element. 2 (Id at 37-38; see
D.I. 400, ex. 1 at 1 (showing that certain Your Shape Fitness Evolved mini-games are the only
Ubisoft products accused of infringing claim 11 of the '997 patent))
But, as Plaintiff pointed out in its own briefing, (D.I. 361 at 37), Ubisoft's argument was
problematic, because if accepted, it would render claims 5 and 7 coextensive. (See D.I. 361 at
37) Claim 7 of the '997 patent claims "[t]he system of claim 5, wherein the training sequence
includes alternating use of the reactive training device with use of the resistive training device."

2

More specifically, Ubisoft argued that "the accused Your Shape mini-games do
not include a 'training sequence' in which the player alternates between the alleged reactive
training device (which Impulse contends is the Kinect, Xbox 360, and the Your shape minigame) and the alleged resistive training device (which Impulse alleges are dumbbells or hand
weights)." (D.I. 333 at 38) It asserts that "[to] the extent that a user uses weights during a Your
Shape game ... the user would use them at the same time and in reaction to the Your Shape
mini-game." (Id. (certain emphasis omitted))
4

('997 patent, col. 45:10-12) This is precisely the limitation that (at least in its briefing) Ubisoft
sought to import into claim 5, and Ubisoft did not point to any meaningful difference that would
remain between claims 5 and 7 if this construction were adopted. (D.I. 386 at 20) The "presence
of a dependent claim that adds a particular limitation raises a presumption that the limitation in
question is not found in the independent claim." Liebel-Flarsheim Co. v. Medrad, Inc., 358 F.3d
898, 910 (Fed. Cir. 2004 ). That presumption is "especially strong" when "the limitation in
dispute is the only meaningful difference between an independent and dependent claim, and one
party is urging that the limitation in the dependent claim should be read into the independent
claim." SunRace Roots Enter. Co., Ltd. v. SRAM Corp., 336 F.3d 1298, 1303 (Fed. Cir. 2003).
Ubisoft's position, which would thus have introduced the limitations of claim 7 into the "training
sequence" term of claim 5, would have run directly contrary to the doctrine of claim
differentiation. 3
Realizing this, Ubisoft later threw out its "requires alternation" position and changed the
focus of its argument. At oral argument, Ubisoft's counsel stated that "[w]e're not talking about
alternating" and argued instead that a training "sequence" "can be resistive/resistive,
reactive/reactive, resistive/reactive, whatever you want to do, but there needs to be a sequence."

3

Claim 25 of the '996 patent also contradicts any claim construction that would
import an "alternating" requirement into the term "training sequence." Claim 25 claims a
"training sequence" and then separately, within the same claim, includes the limitation "wherein
the reactive training bouts are alternated with the resistive training bouts [within the training
sequence]." ('997 patent, col. 46:23-34) If the term "training sequence" already required
alternating between the two kinds of exercise, there would be no need for the more specific
limitation. See WL. Gore & Associates, Inc. v. C.R. Bard, Inc., No. Civil Action No.
11-515-LPS-CJB, 2014 WL 3950663, at *9 (D. Del. Aug. 8, 2014) (noting that adopting a
party's proposed claim construction "would render portions of claim 33 redundant, which is
disfavored") (citing cases).
5

(D.I. 401 at 65) In other words, Ubisoft was now focused on the idea that whatever "training
sequence" means, it cannot allow for the simultaneous use of reactive and resistive training
devices. (Id.)
The Court is not convinced. Ubisoft claims its position is supported by the "the plain and
ordinary meaning" of the word "sequence" as used in "training sequence." (D.I. 401 at 63) But
it offers no dictionary definition for "sequence" (or "training sequence," for that matter). And it
is not at all clear to the Court that the plain and ordinary meaning of "training sequence," as used
in the claim, necessarily carries the meaning that Ubisoft suggests. The term, as used in claim 5,
could simply be meant to refer to a series of movements or exercises-without regard to whether
each individual movement or exercise involved the simultaneous use of a resistive and a reactive
training device (or without regard to whether such devices were used in alternating fashion). In
other words, claim 5 reads as if it could well mean "wherein the reactive training device and the
resistive training device are used in a series of movements or exercises."
The specification seems to bear this out. In one instance, it implies that "training
sequence" is synonymous with the term "training scenario[,]" and it uses "sequence" in a manner
suggesting general reference to a grouping of movements or exercises (one that is agnostic as to
whether reactive and resistive devices are used simultaneously, in alternating fashion or
otherwise). (See '997 patent, col. 40:33-35 ("[T]he recognition of a particular user may be used
to call forth a reactive training scenario or sequence particular to that user.")) Another portion of
the specification also uses "training sequence" in a similar way. (Id., col. 42:7-14 ("For example,
the network administration computer may be programmed to send a user to a strength training
machine which is currently unused, if the unused machine is part of that user's training sequence

6

and has not yet been used by that user in the present training session."))
In its briefing, Ubisoft offered little intrinsic evidence in support of its position. (DJ. 333
at 37-38) The only portion of the patent specification it cited therein was the following:
During the recommended two to three reactive power training
sessions per week, a subject follows a training sequence which
preferably alternates between 30 to 120 second bouts (periods) of
exercise on reactive training devices 602, and resistive strength
enhancing activities on the strength training devices 604.
('997 patent, col. 41 :48-53 (certain emphasis added)) 4 It is not clear that this sentence is intended
to refer to the entire invention, however, rather than a single embodiment, and as such its value is
limited. See, e.g., Cadence Pharm. Inc. v. Exela PharmSci Inc., No. 2014-1184, - F.3d-,
2015 WL 1284235, at *3 (Fed. Cir. Mar. 23, 2015) ("[E]ven if all of the embodiments discussed
in the patent included a specific limitation, it would not be proper to import from the patent's
written description limitations that are not found in the claims themselves.") (internal quotation
marks and citations omitted). And the use of the term "preferably" does not help Ubisoft's
cause. If the training sequence at issue "preferably" requires alternation ofreactive and resistive
training devices (or, put in terms ofUbisoft's updated argument, requires non-simultaneous use
of such devices), that would suggest that such alternation or non-simultaneous use is not

absolutely required as to claim 5 (and thus claim 11). 5

4

The last sentence of this paragraph in the specification, which Ubisoft's counsel
highlighted at oral argument, (DJ. 401 at 63-64), simply furthers this thought: "It is believed that
resistive strength training prepares (fires up) the muscle fibers prior to reactive training to create
a state where the neuromuscular system is most receptive to growth." ('997 patent, col. 41 :5558)
5

Two other portions of the specification that Ubisoft's counsel cited at oral
argument, (DJ. 401 at 63-65), are similarly equivocal. One portion states that "[/]or example,
after a suitably-timed bout of exercise on the reactive training device the user may be prompted
7

In addition to the intrinsic evidence, Ubisoft also cites to testimony from Plaintiffs
invalidity expert, Dr. John Grindon, to the effect that he understood the term "sequence" in this
claim element to mean that "the reactive component [is] followed by a resistive component[.]"
(D.I. 333 at 37-38 (citing D.I. 336, ex. 9 at 293-94)) It is understandable why Ubisoft looks to
score points with this piece of deposition testimony. But the Federal Circuit has made clear that
"conclusory, unsupported assertions by experts as to the definition of a claim term are not useful
to a court[,]" and are to be afforded less weight in a claim construction analysis than are citations
to the intrinsic record. Phillips v. AWHCorp., 415 F.3d 1303, 1318 (Fed. Cir. 2005) ("[A] court
should discount any expert testimony 'that is clearly at odds with the claim construction
mandated by the claims themselves [and] the written description .... "'); see also SkinMedica,
Inc. v. Histogen Inc., 727 F.3d 1187, 1210 (Fed. Cir. 2013) (affording expert testimony "no
weight" with regard to claim construction where it was "conclusory and incomplete[,] lack[ed]
any substantive explanation tied to the intrinsic record[,] and ... appear[ ed] to conflict with the
plain language of the written description"). In this case, Dr. Grindon's testimony consisted of a
short series of answers given in a deposition, without any follow-up discussion regarding the

to proceed to a specific strength training device." ('997 patent, col. 42:1-3 (emphasis added))
The use of "[t]or example" and "may" makes clear that this language is not meant to limit the
invention to one in which reactive and resistive devices are required to be used in an alternating
sequence (or in non-simultaneous fashion). The second cited portion of the specification states
that "[p]referably the bouts of reactive training are sufficiently strenuous to maintain the user's
heart rate in the target zone during the resistive strength training that occurs between bouts of
reactive training." ('997 patent, col. 42:20-23) This sentence certainly is intended to and does
describe the benefits of using resistive and reactive training in an alternating series. But what the
sentence (or the paragraph in which it falls) does not clearly do is discuss what a "training
sequence" or "sequence" is (as those terms are used in the claims). In other words, it does not
clearly state that the invention as a whole or claims 5 and 11 exclude, for example, the use of
resistive and reactive training devices simultaneously. ('997 patent, col. 42:20-23)
8

bases or reasoning behind the answers. As such, it carries little weight in the claim construction
analysis.
In light of the intrinsic evidence, the Court recommends that "training sequence" be
construed to require only a series of movements or exercises, without regard to whether resistive
or reactive training devices are used simultaneously, alternatively, or otherwise. And because
Ubisoft's argument in favor of summary judgment here was solely premised on an understanding
of the claim term that would require alternating between those devices (or at least the nonsimultaneous use of such devices), the Court recommends that Ubisoft' s motion be denied.
Material issues of fact remain as to whether Ubisoft's accused products infringe claim 11 of the
'997 patent.

B.

Willful Infringement

In its motion, Ubisoft further argues that, based on the strength of its non-infringement
and invalidity positions, it is entitled to summary judgment that it cannot be found to have
willfully infringed claim 11 of the '997 patent as a matter oflaw. (D.I. 333 at 38-40) In Jn re
Seagate Tech., LLC, 497 F.3d 1360, 1371 (Fed. Cir. 2007), the Federal Circuit has set out a two-

part test for willfulness, consisting of objective and subjective prongs:
[T]o establish willful infringement, a patentee must show by clear
and convincing evidence that the infringer acted despite an
objectively high likelihood that its actions constituted infringement
of a valid patent. . . . The state of mind of the accused infringer is
not relevant to this objective inquiry. If this threshold objective
standard is satisfied, the patentee must also demonstrate that this
objectively-defined risk (determined by the record developed in the
infringement proceeding) was either known or so obvious that it
should have been known to the accused infringer.
In re Seagate Tech., LLC, 497 F.3d 1360, 1371 (Fed. Cir. 2007) (en bane) (internal citation

9

omitted); see Bard Peripheral Vascular, Inc. v. WL. Gore & Assocs., Inc., 682 F.3d 1003, 100708 (Fed. Cir. 2012) (describing the Seagate test set as including "objective" and "subjective"
prongs). "While the ultimate question of willfulness based on an assessment of the second prong
of Seagate may be a question of fact[,]" the objective prong involves a legal determination and
"should always be decided as a matter oflaw by the judge." Bard, 682 F.3d at 1006-08.
"Objective recklessness will not be found where the accused infringer has raised a 'substantial
question' as to the validity or noninfringement of the patent." Bard Peripheral Vascular, Inc. v.
WL. Gore & Assocs., Inc., 776 F.3d 837, 844 (Fed. Cir. 2015) (internal citations omitted).
The Court concludes that the non-infringement argument that Ubisoft presented is not
sufficient, on its own, to preclude a determination of willful infringement. Ubisoft's noninfringement argument relies upon a proposed construction of a claim term that has insufficient
support in the specification (and, at least as to Ubisoft's prior argument that the claim term
requires alternation, would run directly contrary to the doctrine of claim differentiation). See
Formax, Inc. v. Alkar-Rapidpak-MP Equip., Inc., No. 11-C-298, 2014 WL 2894898, at *2, *6
(E.D. Wis. June 26, 2014) (denying motion for summary judgment of no willful infringement
where the defendant presented a "weak" or "run-of-the-mill limiting argument" regarding claim
construction); Saint-Gobain Autover USA, Inc. v. Xinyi Glass N Am., Inc., 707 F. Supp. 2d 737,
748 (N.D. Ohio 2010), as corrected (Apr. 13, 2010) (denying judgment as a matter oflaw with
regard no willful infringement, and stating that "[b]ecause the Court would have had to
contravene a cardinal principle of claim construction to adopt [Defendant's] construction, namely
to import limitations not found in the claims, the Court cannot find that [Defendant's] position
was reasonable"); cf Tarkus Imaging, Inc. v. Adobe Sys., Inc., 867 F. Supp. 2d 534, 537 (D. Del.

10

2012) (granting summary judgment of no willful infringement where '"the proper claim
construction was a sufficiently close question to foreclose a finding of wilfulness.'") (quoting
Cohesive Techs., Inc. v. Waters Corp., 543 F.3d 1351, 1374 n.4 (Fed. Cir. 2008)).
With regard to Ubisoft' s invalidity defense as to claim 11, the Court has previously
determined that issues of fact (regarding objective considerations of non-obviousness) remain
that, in the end, preclude a recommendation that summary judgment be granted. (D.I. 409 at 3839) Yet in analyzing that defense in significant detail, (id. at 24-39), the Court made clear that
many aspects ofUbisoft's arguments were well-taken, and that the decision as to whether to
recommend a grant of summary judgment was a close one, (id. at 38). In light of the relative
strength of that invalidity defense, the Court is persuaded that as to claim 11, Plaintiff cannot
demonstrate that Ubisoft acted despite an objectively high likelihood that its actions constituted
infringement of a valid patent claim. See, e.g., Robocast, Inc. v. Microsoft Corp., 21 F. Supp. 3d
320, 336 (D. Del. 2014) (granting summary judgment of no willfulness where, inter alia, the
defendant's defenses were "reasonable"); Intellectual Ventures I LLC v. Xilinx, Inc., C.A. No.
10-1065-LPS, 2014 WL 1573542, at *3-4 (D. Del. Apr. 21, 2014) (same); Masimo Corp. v.
Philips Electronics N Am. Corp., C.A. No. 09-80-LPS-MPT, 2013 WL 2920478, at *7 (D. Del.
June 14, 2013) (granting summary judgment of no willful infringement where the defendant
"presented legitimate and credible defenses"). 6
IV.

CONCLUSION

6

To the extent that Defendant EA also seeks summary judgment of no willful
infringement as to claim 11, the Court recommends that EA's motion be granted as well, for the
same reasons. (See D.I. 400, ex. 1 at 1 (listing claim 11 of the '997 patent as being asserted
against EA))
11

For the reasons set forth above, the Court recommends that Defendants' Motion for
Summary Judgment ofNoninfringement be DENIED as to non-infringement of claim 11 of the
'997 patent by Ubisoft, but that it be GRANTED as to no willful infringement regarding claim
11.
