Case No. 2:14-CV-61-JRG

MEMORANDUM OPINION AND ORDER
Before the Court are a number of motions concerning technical expert testimony: (1) Motion
to Exclude Portions of the Reports and Testimony of Jean Renard Ward (Dkt. No. 679); (2) Motion
to Exclude Portions of the Reports and Testimony of Dr. Brian Noble (Dkt. No. 683); (3) Motion to
Exclude Portions of the Reports and Testimony of Dr. Steve White (Dkt. No. 684), (4) Motion to
Exclude Portions of the Reports and Testimony of Atul Prakash (Dkt. No. 685), (5) Motion to
Exclude Portions of the Noninfringement Reports and Testimony of Paul Clark, Brian Noble, John
Kelly, and Gene Tsudik (Dkt. No. 688), (6) Motion to Exclude Portions of the Reports and
Testimony of Dr. Paul Clark (Dkt. No. 690), (7) Motion to Exclude Portions of the Reports and
Testimony of Dr. John P.J. Kelly (Dkt. No. 692), all filed by Plaintiff ContentGuard Holdings, Inc.
Also before the Court is (8) Defendants’ Combined Motion to Strike Portions of the Expert Reports

and Testimony of Michael T. Goodrich and David Martin (Dkt. No. 721). At the Court’s request, the
Defendants consolidated the separate motions filed by various defendants on June 26, 2015, at docket
number 232 in Case No. 2:14-cv-61, and docket numbers 665, 668, 673, 675, 677, 687, and 691 in

Case No. 2:13-cv-1112 into the Combined Motion to Strike Portions of the Expert Reports and
Testimony of Michael T. Goodrich and David Martin (Dkt. No. 721). The Court requested that the
parties submit copies of each expert report in dispute, (Dkt. No. 782), which have subsequently been
reviewed by the Court. The Court held a hearing on these motions on August 5, 2015. (Dkt. No.
827.) For the reasons set forth below, the motions to strike are GRANTED to the extent specified
below, and are otherwise DENIED.

I.

Background

On December 18, 2013, ContentGuard filed suit against Amazon, Apple, BlackBerry,
Huawei, and Motorola Mobility asserting claims of patent infringement of the patents in this suit.
(Dkt. No. 1). On January 17, 2014, ContentGuard filed an amended complaint asserting the
same patents against HTC and Samsung. (Dkt. No. 22).
ContentGuard has asserted the following twenty claims from six related patents issued to
Mark Stefik: Claims 1, 3, 6, 8, 11, and 13 from U.S. Patent No. 8,393,007 (“the ’007 patent”);
Claims 1, 7, and 13 from U.S. Patent No. 8,370,956 (“the ’956 patent”); Claims 1 and 8 from
U.S. Patent No. 7,523,072 (“the ’072 patent”); Claims 18, 21, and 34 from U.S. Patent No.
7,269,576 (“the ’576 patent”); and Claims 1, 21, and 58 from U.S. Patent No. 6,963,859 (“the
’859 patent”) (collectively, the “Stefik patents”). ContentGuard has also asserted the following
five claims from two related patents issued to Mai Nguyen: Claims 1 and 5 of U.S. Patent No.
7,774,280 (“the ’280 patent”); and Claims 1, 3, and 5 from U.S. Patent No. 8,001,053 (“the ’053
patent”) (collectively, the “Nguyen patents”).

II.

LEGAL STANDARD

An expert witness may provide opinion testimony if “(a) the expert’s scientific, technical,
or other specialized knowledge will help the trier of fact to understand the evidence or to
determine a fact in issue; (b) the testimony is based on sufficient facts or data; (c) the testimony
is the product of reliable principles and methods; and (d) the expert has reliably applied the
principles and methods to the facts of the case.” FED. R. EVID. 702.
Rule 702 requires a district court to make a preliminary determination, when requested,
as to whether the requirements of the rule are satisfied with regard to a particular expert’s
proposed testimony. See Kumho Tire Co. v. Carmichael, 526 U.S. 137, 149 (1999); Daubert v.
Merrell Dow Pharm., Inc., 509 U.S. 579, 592–93 (1993). District courts are accorded broad
discretion in making Rule 702 determinations. Kumho Tire, 526 U.S. at 152 (“[T]he trial judge
must have considerable leeway in deciding in a particular case how to go about determining
whether particular expert testimony is reliable.”). Although the Fifth Circuit and other courts
have identified various factors that the district court may consider in determining whether an
expert’s testimony should be admitted, the common nature of these factors direct the trial court
to consider as its ultimate inquiry whether the expert’s testimony is sufficiently reliable and
relevant to be helpful to the finder of fact and thus to warrant admission at trial. United States v.
Valencia, 600 F.3d 389, 424 (5th Cir. 2010).
Importantly, in a jury trial setting, the Court’s role under Daubert is not to weigh the
expert testimony to the point of supplanting the jury’s fact-finding role. See Micro Chem., Inc. v.
Lextron, Inc., 317 F.3d 1387, 1391–92 (Fed. Cir. 2003) (applying Fifth Circuit law) (“When, as
here, the parties’ experts rely on conflicting sets of facts, it is not the role of the trial court to
evaluate the correctness of facts underlying one expert’s testimony.”); Pipitone v. Biomatrix,
Inc., 288 F.3d 239, 249–50 (5th Cir. 2002) (“‘[t]he trial court’s role as gatekeeper [under
3

Daubert] is not intended to serve as a replacement for the adversary system.’ . . . Thus, while
exercising its role as a [gatekeeper], a trial court must take care not to transform a Daubert
hearing into a trial on the merits”) (quoting FED. R. EVID. 702 advisory committee note).
Instead, the Court’s role is limited to that of a gatekeeper, ensuring that the evidence in dispute is
at least sufficiently reliable and relevant to the issue before the jury so as to be appropriate for
the jury’s consideration. See Pipitone, 288 F.3d at 249–50. As the Supreme Court explained in
Daubert, 509 U.S. at 596, “[v]igorous cross-examination, presentation of contrary evidence, and
careful instruction on the burden of proof are the traditional and appropriate means of attacking
shaky but admissible evidence.” See Mathis v. Exxon Corp., 302 F.3d 448, 461 (5th Cir. 2002).

A.

DISCUSSION

Prior Art Related Grounds for the Motions to Strike
1.

Pfleeger References

The Court previously excluded the Pfleeger references from Defendants’ invalidity
contentions because the Court found that Defendants had not shown good cause sufficient to add
a reference to their invalidity contentions late in the litigation when they had previously known
about the reference but not asserted it for over a year. (June 23, 2015, H’rg Tr., Dkt. No. 660, at
35:8–13.)

Plaintiff argues that Defendants Apple, Google, HTC, Huawei, Motorola, and

Samsung are now attempting to maneuver around the Court’s previous order by including
Pfleeger as a state-of-the-art reference, rather than an invalidity reference. (Dkt. No. 679, at 11–
12.) Defendants argue that even though the Court excluded Pfleeger as an invalidity reference,
Pfleeger can still be used to show the state of the art, particularly as it was known to the inventor,
at the time the patent was filed. (Dkt. No. 749, at 15.) Further, Defendants explicitly affirmed
that they would not attempt to show Pfleeger as an anticipation or obviousness reference. (Id.);
see also (Aug. 5, 2015, H’rg Tr., Dkt. No. 827, at 9:23–10:2.)
4

The Court is sympathetic to Defendants’ position regarding the need to show the state of
the prior art and accepts counsel’s representation that Defendants would not overtly use Pfleeger
as a per se invalidity reference. However, the Court, after considering the briefing and oral
argument, finds that the portions of Mr. Ward’s report containing discussion of the substance of
Pfleeger must be stricken in view of the Court’s previous order, including at least from
Paragraphs 113, 121, 132, 134, 139, 140, 141, 178, 195, 391-94, 402-05, 511-524, 580, 615-16,
627-28, 641-42, 655-56, 669-70, 683-84, 702-03, 716-17, 739-40, and 746 of Mr. Ward’s report.
After examining the paragraphs in question, including the paragraphs that Defendants expressly
identified as only touching on the state of the prior art, the Court finds it difficult to completely
separate the use of Pfleeger as a state-of-the-art reference from the use of Pfleeger as an
invalidity reference: the use for one purpose unavoidably bleeds into the other. Accordingly, the
Court GRANTS Plaintiff’s motion (Dkt. No. 679) as it pertains to the Pfleeger references in the
above cited paragraphs.
2.

VDE References

The Court previously denied Apple’s request to amend its invalidity contentions with any
VDE references other than U.S. Patent. No. 5,892,900 (“Ginter”), because the Court found that
Apple had not shown an adequate basis to overcome the prejudice to ContentGuard of adding the
VDE references this late in litigation. (April 28, 2015, H’rg Tr., Dkt. No. 577, at 44:5–16.) The
Court also granted a subsequent motion to exclude based on its earlier order. (Dkt. No. 820.)
Plaintiff argues that Defendant Apple has never asserted the “VDE system” against the Nguyen
patents and is now attempting to circumvent the Court’s previous order by “recit[ing]
contentions (including two figures) about ‘the VDE system’ that are based not on anything in the
public Ginter patent reference, but on deposition testimony from Mr. Ginter regarding the
operation of the precluded VDE system.” (Dkt. No. 685, at 14.) Apple argues that Ginter was
5

always asserted against the Nguyen patents and that the “two embodiments (‘traveling objects’ and
‘stationary objects’) described and depicted in paragraph 269 of Dr. Prakash’s report, and also
described by Mr. Ginter during his deposition, are indeed disclosed in the Ginter patent.” (Dkt. No.

748, at 14.)
After considering the briefing and oral argument, the Court finds that the portions of the
sentences from Paragraph 269 of Dr. Prakash’s report, which contain information about the VDE
systems which is not directly from the Ginter patent, including the portions of the report based
on information obtained from Mr. Ginter’s deposition testimony, must be stricken in view of the
Court’s previous order. Accordingly, the Court GRANTS Plaintiff’s motion (Dkt. No. 685) as it
pertains to information about the VDE system that is not disclosed directly from the Ginter
patent.
3.

Wyman References

Plaintiff argues that “[d]espite amending their Invalidity Contentions multiple times,
Defendants never asserted [U.S. Patent Nos. 5,260,999 (the “’999 Patent”) and 5,204,897 (the
“’897 Patent”) (collectively, “the Wyman patents”)] as prior art against the meta-rights patents in
their Invalidity Contentions.” (Dkt. No. 679, at 11; Dkt. No. 685, at 13.) Plaintiff further argues
that Defendants are now attempting to assert “[the Wyman patents] against the meta-rights
patents for the first time in [their] expert report[s].” (Dkt. No. 679, at 11; Dkt. No. 685, at 13.)
The ’999 Patent had previously been asserted against at least the Stefik patents. (Dkt. No. 749,
at 14.) The non-Apple Defendants argue that they did not “appreciate the full relevance of [the
’999 Patent] to the Nguyen patents,” (id.), until “ContentGuard asserted an entirely new theory
of infringement regarding ‘meta-rights’ in its April 20, 2015 fifth infringement contentions,”
(Dkt. No. 805, at 4). Defendants further argue that they “promptly identified [the ’999 Patent] as
being relevant to the invalidity of the Nguyen patents [upon realizing the ’999 Patent’s
6

relevance],” (Dkt. No. 749, at 14). Apple argues that “Dr. Prakash’s report does not assert [the
’897 Patent] as a § 102 or 103 reference against the Nguyen patents.” (Dkt. No. 748, at 13.)
After considering the briefing and oral argument, the Court finds that assertion of the
Wyman patents against the Nguyen patents is untimely, and as a result, those portions of Mr.
Ward’s report (Paragraphs 882–887 and Exhibits X1 and X2) and Dr. Prakash’s report
(Paragraphs 182 and 222) should be stricken. Accordingly, the Court GRANTS Plaintiff’s
motions (Dkt. Nos. 679 and 685) as they pertain to the Wyman patents as invalidity references
against the Nguyen patents.
B.

Claim Construction Related Grounds for the Motions to Strike

Plaintiff argues that portions of Defendants’ various experts’ reports and testimony are
improper because Defendants’ respective experts misapply the Court’s claim construction. See
(Dkt. No. 679, at 5–11; Dkt. No. 683, at 4–12; Dkt. No. 684, at 4–9; Dkt. No. 685, at 5–13; Dkt.
No. 690, at 4–13; Dkt. No. 692, at 4–12.) Similarly, Defendants argue that portions of Plaintiff’s
experts’ reports and testimony are improper because Plaintiff’s experts misapply the Court’s
claim construction. See (Dkt. No. 721, at 1.)
As an initial matter, the Court notes, that during a hearing held on July 27, 2015, the
Court asked the parties whether any outstanding claim construction issues needed to be dealt
with prior to trial. See (July 27, 2015, H’rg Tr., Dkt. No. 818, at 31:23–32:1.) Other than one
discrete issue that has already been completely briefed (a motion for reconsideration, Dkt. No.
480), no party identified any remaining claim construction issues.

See (id. at 32:2–13.)

Regarding the particular expert reports and testimony disputes at hand, IT IS ORDERED that
no experts are to render any conclusions regarding the scope of the patents-in-suit or particular
claim limitations that deviate from this Court’s Claim Construction Memorandum and Order
(Dkt. No. 459).

Accordingly, all experts, whether Plaintiff’s or Defendants’, are hereby
7

excluded from providing any opinions that violate these constraints, and any portions of their
reports in conflict with this Order are stricken.
Further, all experts are hereby excluded from providing any opinions based on an
interpretation of the Court’s construction that is the equivalent of any construction that the Court
previously considered and expressly rejected.

In particular, with regard to the following

previously construed claim terms, the identified claim construction arguments have previously
been considered and expressly rejected in the Court’s Claim Construction Order, and therefore,
the Court ORDERS that:


“rights,” “usage rights,” “usage rights information” – No expert may opine or
insinuate that a mere association between the content and the usage rights is
enough to meet the requirement that the usage rights be “attached” to the content.
See (Dkt. No. 459, at 33.) A mere reference, with nothing more to indicate that
the usage rights should be attached or treated as attached to the content, is not
enough. The bolded portion from the following sentence from paragraph 48 of
Mr. Goodrich’s report is an exemplary opinion implicated by this Order and must
be stricken: “Thus usage rights may be attached to content by placing them inside
the same data structure or file or through the use of links or references to the
content from the data structure containing the usage right.” (Dkt. No. 721-7, at
¶48 (emphasis added).)



“rights,” “usage rights,” “usage rights information” – No expert may opine or
insinuate that the attachment between the content and the usage rights must be
permanent. See (Dkt. No. 459, at 33.) The bolded portion from the following
sentences from paragraph 160 of Mr. Ward’s report are exemplary opinions

8

implicated by this Order and must be stricken: “A key feature of the present
invention is that usage rights are permanently ‘attached’ to the digital work. . . .
Thus, the usage rights and any associated fees assigned by a creator and
subsequent distributor will always remain with a digital work.” (Dkt. No. 679-1,
at ¶ 160 (emphasis added).)


“repository” and “trusted” – No expert may opine or insinuate that a
“repository” or “trusted device” must maintain the three integrities “at all times.”
See (Dkt. No. 459, at 15.) The bolded portion from the following sentence from
paragraph 138 of Mr. Clark’s report is an exemplary opinion implicated by this
Order and must be stricken: “Thus, if an accused repository, recipient computing
device, or recipient apparatus allows access to any ‘information’ by a nontrusted
system (including, but not limited to ‘content’), then it cannot be found to possess
the required ‘physical integrity’ and, accordingly, cannot be a ‘repository,’ a
‘trusted’ device, or ‘trusted’ apparatus.” (Dkt. No. 690-1, at ¶ 138 (emphasis
added).)

Accordingly, the Court GRANTS Plaintiff’s motions (Dkt. No. 679, Dkt. No. 683, Dkt.
No. 684, Dkt. No. 685, Dkt. No. 690, Dkt. No. 692) and Defendants’ Motion (Dkt. No. 721) only
as they relate to the claim construction positions explicitly identified above.

The claim

construction positions of Plaintiff’s motion and Defendants’ motions are DENIED in all other
respects.
C.

Doctrine of Equivalents Related Grounds for the Motions to Strike

Defendants argue that Plaintiff’s disclosure of Plaintiff’s Doctrine of Equivalents
(“DOE”) theory is untimely. See (Dkt. No. 721, at 25–26.) Defendants also argue that the DOE
theory improperly attempts to revive a claim construction position previously rejected by the
9

Court, vitiates the Court’s claim construction ruling, and is barred by prosecution history
estoppel (“PHE”). See (id. at 16–25.) Relatedly, Apple argues that Plaintiff did not adequately
or timely disclose that the use of the “Messages” program to transfer files between Apple
employees met the “behavioral integrity” requirement of the patents-in-suit. See (id. at 26–28.)
Plaintiff responds that, as an initial matter, Plaintiff properly amended its infringement
contentions within 30 days of the Court’s Claim Construction Order, as allowed under the Local
Rules, and adequately disclosed Plaintiff’s infringement theories in its infringement contentions.
See (Dkt. No. 740, at 18–21.) Further, Plaintiff argues that it is not attempting to revive any
rejected claim construction positions and that though the Court rejected Plaintiff’s proposed
claim construction, the Court did not expressly find that the “behavioral integrity” limitation
could not be met through the use of an equivalent to a “digital certificate.” See (id. at 11–14.)
Plaintiff also argues that, in regard to Apple, any late disclosure of infringement theories, to the
extent that such disclosure was late, was a result of Apple’s own “deficient source code
production and belated depositions.” See (id. at 20–21.)
The Court will address the PHE arguments later in this Order. After considering the
briefing and oral argument, the Court finds the DOE disclosures were timely. Accordingly, the
Court DENIES Defendants’ motion (Dkt. No. 721) as it pertains striking the DOE theories
disclosed in Mr. Goodrich’s and Mr. Martin’s reports. The Court notes, however, that the Court
expressly rejected the inclusion of the language, “in other words, an assurance that the software
comes from a source known to the repository,” in the construction of “behavioral integrity,”
because the “additional language . . . would tend to broaden the scope of the disputed term.”
(Dkt. No. 459, at 19–21.) In accordance with that decision, IT IS ORDERED that no expert

10

may opine or insinuate that a “digital certificate” is simply “an assurance that the software comes
from a source known to the repository.”
D.

Prosecution History Estoppel Related Grounds for the Motions to Strike

Plaintiff argues that portions of Dr. Kelly’s report improperly raise legal issues, such as
ensnarement and PHE, which should not be presented to the jury. See (Dkt. No. 692, at 12–13.)
Apple specifically responds that Dr. Kelly’s report properly discloses the underlying facts
necessary to present Apple’s PHE arguments.

See (Dkt. No. 738, at 11–12.)

Relatedly,

Defendants argue that Mr. Goodrich’s and Mr. Martin’s theories that “behavioral integrity” is
met through the DOE are barred by PHE. See (Dkt. No. 721, at 21.) ContentGuard responds by
arguing that, procedurally, the PHE arguments have been waived by Defendants’ silence prior to
the Daubert motion and that, substantively, the patentee did not clearly surrender subject matter.
See (Dkt. No. 740, at 15.) Defendants respond by arguing that the DOE infringement theory was
not disclosed until April 20, 2015, a day before the deadline to file the letter briefs for dispositive
motions, which is why the PHE arguments were not raised prior to the Daubert stage. See (Aug.
5, 2015, H’rg Tr., Dkt. No. 827, at 107:11–108:2.)
After considering the briefing and oral argument, the Court finds that PHE arguments are
untimely, and as a result, those portions of Dr. Kelly’s report (Paragraphs 296–336) are stricken.
Though Defendants argue that the PHE arguments are a response to Plaintiff’s Amended
Infringement Contentions served on the day that the letter briefing was due, Defendants did not
request an extension or any relief to rectify the problems which they assert were created by this
alleged late amendment. For example, Defendants did not request leave to file a motion for
summary judgment in which they could have laid out the particular timing issues at play here.
Accordingly, the Court GRANTS Plaintiff’s motion (Dkt. No. 692) as it pertains to the
prosecution history estoppel arguments contained in Dr. Kelly’s report and DENIES
11

Defendants’ motion (Dkt. No. 721) as it pertains to a prosecution history estoppel bar to
ContentGuard’s assertion of the doctrine of equivalents.
E.
ContentGuard’s Daubert Motion to Exclude Portions of the Noninfringement
Reports and Testimony Related to Rooting, Jailbreaking, and TunesKit Software
Plaintiff argues that portions of Defendants’ noninfringement experts’ reports and
testimony are improper because Defendants’ respective experts relied on facts, including tests,
that were not properly disclosed during fact discovery, modified the accused instrumentalities
such that any test results are irrelevant, and failed to disclose enough facts to determine whether
the tests were reliable. See (Dkt. No. 688, at 3–15.) Defendants first respond by arguing that the
facts underlying their tests were timely disclosed and that they did not need to disclose their
testing methodology. See, e.g., (Dkt. No. 750, at 3–5.) Defendants further argue that their test
results are relevant because they prove that the accused instrumentalities do not meet the claim
limitations of the Patents-in-Suit, particularly as they relate to the three integrities. See, e.g.,
(Dkt. No. 721, at 1.) Finally, Defendants argue that the experts provided more than sufficient
detail such that the tests could be reproduced and determined reliable. See, e.g., (Dkt. No. 750,
at 12–14.).
As an initial matter, the Court does not find the timing of the disclosure of this evidence
to be improper. Defendants timely disclosed the facts that are the subject of the tests. However,
after considering the briefing and oral argument, the Court does find that the rooting and
jailbreaking related modifications made by Dr. Clark, Dr. Noble, and Dr. Kelly render the test
results irrelevant and the portions from their respective reports and testimonies relating to such
are stricken. After much consideration, the Court has determined that the issue is not whether it
is possible to eventually modify the accused instrumentalities so that they no longer meet the
claim limitations of the asserted patents.

Rather, the question is whether the accused
12

instrumentalities, as sold, meet all the claim limitations as construed by the Court. Similarly, the
Court also finds that the installation of the TunesKit Application renders Dr. Kelly’s test results
irrelevant and the portions from his report and testimony relating to such are stricken.
Accordingly, the Court GRANTS Plaintiff’s motion (Dkt. No. 688).
IV.
