`
`Introduction
`
`
`
`Case No. IPR2015-00870
`
`Patent Owner VirnetX Inc. respectfully submits this Preliminary Response
`
`in accordance with 35 U.S.C. § 313 and 37 C.F.R. § 42.107, responding to the
`
`Petition for Inter Partes Review (the “Petition”) filed by Apple Inc. against Patent
`
`Owner’s U.S. Patent No. 8,560,705 (“the ’0705 patent”). Patent Owner requests
`
`that the Board not institute inter partes review for several reasons.
`
`First, Petitioner relies on material that it has not shown is a “patent[] or
`
`printed publication[]” under 35 U.S.C. § 311(b). Second, Petitioner proposes
`
`redundant grounds without identifying how any one ground improves on any other,
`
`contravening Board precedent requiring petitioners to identify differences in
`
`proposed rejections. Next, Petitioner has not met its burden of demonstrating a
`
`reasonable likelihood of prevailing in proving unpatentability of any challenged
`
`’0705 patent claim. The Petition also fails to identify where and what in the prior
`
`art discloses each claimed feature, violating the particularity requirements of 35
`
`U.S.C. § 312(a)(3) and 37 C.F.R. § 42.104(b). And finally, Petitioner proposes a
`
`number of incorrect claim constructions upon which it bases its unpatentability
`
`grounds. Each of these reasons requires denial of institution.
`
`II. The Petition Fails to Meet the Requirements for Instituting an
`Inter Partes Review
`The grounds that may be raised in a petition for inter partes review (IPR) are
`
`limited to those “that could be raised under section 102 or 103 and only on the
`
`
`
`
`
`
`basis of prior art consisting of patents or printed publications.” 35 U.S.C. § 311(b).
`
`Case No. IPR2015-00870
`
`In addition, the Board will not consider redundant grounds and to the extent they
`
`are proposed, Petitioner carries the burden of “articulat[ing] a meaningful
`
`distinction in terms of relative strengths and weaknesses with respect to application
`
`of the prior art disclosures to one or more claim limitations.” ScentAir Techs., Inc.
`
`v. Prolitic, Inc., IPR2013-00180, Paper No. 18 at 3 (Aug. 26, 2013); see also Idle
`
`Free Sys., Inc. v. Bergstrom, Inc., IPR2012-00027, Paper No. 26 at 3 (June 11,
`
`2013) (“[A]t [the] time of institution the Board analyzes the petition on a claim-by-
`
`claim, ground-by-ground basis, to eliminate redundant grounds.”) To be instituted,
`
`a petition must also “show[] that there is a reasonable likelihood that the petitioner
`
`would prevail with respect to at least 1 of the claims challenged in the petition.”
`
`35 U.S.C. § 314(a). This showing requires that the petition “identif[y], in writing
`
`and with particularity, each claim challenged, the grounds on which the challenge
`
`to each claim is based, and the evidence that supports the grounds for the challenge
`
`to each claim.” 35 U.S.C. § 312(a)(3). Petitioner fails to meet each of these
`
`requirements.
`
`A. The Petition Improperly Relies on Material That It Fails to
`Establish Is Statutory Prior Art
`Prior art relied on in a petition for inter partes review may only consist of
`
`“patents or printed publications.” 35 U.S.C. § 311(b). As such, the burden is on
`
`Petitioner to establish that RFC 2401, which is not a patent and on which Petitioner
`
`
`
`2
`
`
`
`
`relies for its proposed ground of unpatentability, was “sufficiently accessible to the
`
`Case No. IPR2015-00870
`
`public interested in the art.” In re Klopfenstein, 380 F.3d 1345, 1348 (Fed. Cir.
`
`2004); see also Actavis, Inc. v. Research Corp. Techs., Inc., IPR2014-01126, Paper
`
`No. 22 at 9-13 (Jan. 9, 2015) (finding that “Petitioner has not satisfied its burden to
`
`prove that [a] thesis is a printed publication under § 102(b)”); L-3 Comm.
`
`Holdings, Inc. v. Power Survey, LLC, IPR2014-00832, Paper No. 9 at 12 (Nov. 14,
`
`2014) (“The party seeking to introduce the reference ‘should produce sufficient
`
`proof of its dissemination or that it has otherwise been available and accessible to
`
`persons concerned with the art to which the document relates and thus most likely
`
`to avail themselves of its contents.’”); A.R.M., Inc. v. Cottingham Agencies Ltd.,
`
`IPR2014-00671, Paper No. 10 at 7 (Oct. 3, 2014).
`
`Petitioner merely alleges that RFC 2401 (Ex. 1008) “was published in
`
`November 1998.” (Pet. at 24 (citing Ex. 1008 at 1).) Petitioner’s allegation is
`
`insufficient to overcome Petitioner’s burden of proving that RFC 2401 is a printed
`
`publication. First, Petitioner does not explain in the Petition how or why
`
`November 1998 is the publication date for RFC 2401. A review of Petitioner’s 55
`
`exhibits, reveals testimony by Petitioner’s expert, Dr. Tamassia, on the subject of
`
`RFC 2401’s publication date, but this testimony is never cited to nor discussed in
`
`the Petition. Second, even if Dr. Tamassia’s testimony was improperly considered
`
`
`
`3
`
`
`
`
`to be part of the Petition, it fails to establish that RFC 2401 was “sufficiently
`
`Case No. IPR2015-00870
`
`accessible to the public interested in the art” as of the alleged publication date.
`
`As indicated above, the Petition nakedly asserts that RFC 2401 was
`
`published on November 1998. But the Petition provides no explanation why RFC
`
`2401 was “sufficiently accessible to the public interested in the art” as of its
`
`alleged publication date. This deficiency is fatal to the Petition’s claims regarding
`
`the status of RFC 2401 as a printed publication. See Square, Inc. v. Unwired
`
`Planet, LLC, CBM2014-00156, Paper 22 at 6-7 (Feb. 26, 2015) (explaining that a
`
`Petition’s naked assertion of a publication date is insufficient because the Peitioner
`
`“must prove in its Petition” the references’ publication date and “that, as of that
`
`date, [the reference] was publicly accessible.”) (emphasis added); compare Square,
`
`Inc., CBM2014-00156, Paper 2 at 39 (July 11, 2014), with Pet. at 24.
`
`The nominal recitation of the alleged publication date on the first page of the
`
`RFC, (see Ex. 1008 at 1, Ex. 1013 at 1), cannot and does not relieve Petitioner of
`
`its burden of explaining in the Petition why RFC 2401 was “sufficiently
`
`accessible to the public interested in the art” as of its alleged publication date. And
`
`while RFC 2401 nominally includes a date, nowhere in the document is there any
`
`indication as to what the date means. (See Ex. 1008 at 1, Ex. 1013 at 1.) Like
`
`here, in Square, Inc., the alleged publication date (September 30, 1996) also
`
`appeared on the face of the cited reference (Vazvan). Square, Inc., CBM2014-
`
`
`
`4
`
`
`
`
`00156, Paper 22 at 6-7. But the Board held that it was Petitioner’s burden to offer
`
`Case No. IPR2015-00870
`
`proof “in its Petition” of Vazvan’s publication date, which Petitioner did not, and
`
`“it [was] not the Board’s task to prove that the date on the face of Vazvan is not the
`
`publication date.” Id.
`
`Furthermore, the Petition’s clear deficiencies cannot be remedied by Dr.
`
`Tamassia’s declaration. First and foremost, the Petition never cites to any of Dr.
`
`Tamassia’s testimony regarding the publication date of RFC 2401. Nor can it be
`
`expected or assumed that Dr. Tamassia’s declaration and all its arguments, which
`
`cover multiple patents and number several hundred pages, are simply part of the
`
`Petition. Such a “practice amounts to incorporation by reference—which is
`
`impermissible under [the Board’s] rules.” See Apple Inc. v. Contentguard
`
`Holdings, Inc., IPR2015-00450, Paper No. 9 at 10 (June 29, 2015), citing 37
`
`C.F.R. § 42.6(a)(3) (“Arguments must not be incorporated by reference from one
`
`document into another document.”). Even incorporating just those portions of Dr.
`
`Tamassia’s declaration that discuss the alleged publication date of RFC 2401—
`
`which would still be improper and without precedent given that the Petition never
`
`cites to these paragraphs—would incorporate several pages into the Petition and
`
`would serve to “circumvent the page limits imposed on petitions for inter partes
`
`review.” Cisco Sys., Inc. v. C-Cation Techs., LLC, IPR2014-00454, Paper 12 at 7–
`
`
`
`5
`
`
`
`
`10 (Aug. 29, 2014) (informative) (refusing to consider “arguments that are not
`
`Case No. IPR2015-00870
`
`made in the Petition, but are instead incorporated by reference . . . .”).
`
`But even assuming Dr. Tamassia’s testimony could be (improperly) read
`
`into the Petition, Petitioner still has not met its burden because it fails to establish
`
`(1) the alleged publication date, and (2) that RFC 2401 would have been
`
`sufficiently accessible to the public interested in the art on its alleged publication
`
`date. First, Dr. Tamassia does not establish that RFC 2401 was actually published
`
`in November 1998, as alleged by the Petition. In his declaration, Dr. Tamassia
`
`refers to RFC 2026 in his discussion of how RFCs are “typically” released. (Ex.
`
`1005 at ¶ 190.) RFC 2026, provided by the same “Network Working Group” as
`
`RFC 2401 (compare Ex. 1036 at 1, with Ex. 1008 at 1), purports to “document[]
`
`the process used by the Internet community for the standardization of protocols
`
`and procedures” and to “define[] the stages in the standardization process, the
`
`requirements for moving a document between stages and the types of documents
`
`used during this process.” (See Ex. 1036 at 1.)1 Dr. Tamassia then makes an
`
`1 The Petition does not cite to RFC 2026 or to any testimony citing to the
`
`
`document. Therefore, it cannot properly be relied upon to establish RFC 2401 as a
`
`printed publication. However, Patent Owner addresses the document to the extent
`
`the Board considers statements by Petitioner’s expert regarding RFC 2026 not
`
`cited in the Petition. As explained, these statements, and RFC 2026 itself, still fail
`
`
`
`6
`
`
`
`
`uncorroborated statement that “[t]he publication date of each RFC is . . . typically
`
`Case No. IPR2015-00870
`
`in the top right corner of the first page of the document.” (Ex. 1005 at ¶ 190.) But
`
`Dr. Tamassia never discusses the basis for this statement and so his testimony
`
`should be accorded no weight. See 37 C.F.R. § 42.65(a). Dr. Tamassia has not
`
`been established as someone familiar with, let alone an expert in, the workings of
`
`the Internet Engineering Task Force (IETF) – the body responsible for the RFCs.
`
`Further, neither Dr. Tamassia nor the Petition establish or even allege that Dr.
`
`Tamassia has personal knowledge that RFC 2401 was actually released on its
`
`alleged publication date in the way he claims RFCs were typically released.
`
`Hence, because Dr. Tamassia has not been shown to be an expert with respect to
`
`IETF and has also not been shown to have personal knowledge of the facts, his
`
`uncorroborated statements regarding the publication date of RFC 2401 should be
`
`accorded no weight. Id.
`
`Second, Dr. Tamassia’s declaration does not establish that RFC 2401 was
`
`“sufficiently accessible to the public interested in the art” as of its alleged
`
`publication date. Thus, even assuming the RFCs were released in the manner Dr.
`
`Tamassia alleges (though Patent Owner submits that Petitioner has not provided
`
`
`to establish that RFC 2401 qualifies as a printed publication within the meaning of
`
`Section 311(b).
`
`
`
`7
`
`
`
`
`any evidence to establish that it was), Petitioner has still not established that RFC
`
`Case No. IPR2015-00870
`
`2401 qualifies as a printed publication within the meaning of Section 311(b).
`
`RFC 2026 generally states that “RFCs can be obtained from a number of
`
`Internet hosts using anonymous FTP, gopher, World Wide Web, and other Internet
`
`document-retrieval systems.” (Id. at 6.) But RFC 2026 does not explain how the
`
`public interested in the art would become aware of the location of such Internet
`
`document-retrieval systems. Indeed, Dr. Tamassia suggests that the intended
`
`audience of RFC 2401 would have been limited to the “Network Working Group,”
`
`stating that the nominal date that RFC documents are “published” merely “starts a
`
`period for others to provide comments on the document” (in particular, what RFC
`
`2026 refers to as “community review”). (See Ex. 1005 at ¶ 190; Ex. 1036 at 20.)
`
`In the past, the Board has found that references similar to RFC 2401 are not
`
`statutory prior art. For example, in Samsung Elecs. Co. v. Rembrandt Wireless
`
`Techs., LP, IPR2014-00514, Paper No. 18 at 5, 7 (Sep. 9, 2014), the petitioner
`
`relied on a “Draft Standard” of the Institute of Electrical and Electronics Engineers
`
`(“IEEE”). The Board found that the petitioner had failed to establish the Draft
`
`Standard qualified as a printed publication because the petitioner did not provide
`
`evidence as to whether the Draft Standard was made available to persons outside of
`
`the IEEE “Working Group” responsible for the Draft Standard and how members
`
`of the public would have known about the Draft Standard. See id. at 7-8.
`
`
`
`8
`
`
`
`
`Similarly, in Elec. Frontier Found. v. Pers. Audio, LLC, IPR2014-00070, Paper
`
`Case No. IPR2015-00870
`
`No. 21 at 22-24 (Apr. 18, 2014), the Board found that a reference was not a printed
`
`publication where a “Petitioner fail[ed] to provide any information regarding [a
`
`reference] posting, the group [to which the reference was posted], who is in the
`
`group, or the size of the group.” In both cases, the Board denied institution based
`
`on these findings. See Samsung Elecs., IPR2014-00514, Paper No. 18 at 10
`
`(“Because Petitioner has not met its burden in establishing that Draft Standard is a
`
`‘printed publication’ and, thus, prior art, Petitioner has not shown a reasonable
`
`likelihood of prevailing on the grounds asserted.”); Elec. Frontier Found.,
`
`IPR2014-00070, Paper No. 21 at 26.
`
`Petitioner has similarly failed to meet its burden to establish that RFC 2401
`
`is a printed publication. For example, Petitioner has not provided any evidence as
`
`to (1) whether RFC 2401 was made available to persons outside of the “Network
`
`Working Group”; (2) how members of the public outside of the “Network Working
`
`Group” would have known about RFC 2401; (3) who is in “Network Working
`
`Group”; or (4) the size of the Network Working Group. Therefore, because the
`
`Petition does not establish that RFC 2401 was printed publications to qualify as
`
`prior art, and because all of Petitioner’s proposed rejections rely on RFC 2401, the
`
`Board should deny institution of the Petition.

`
`Case No. IPR2015-00870
`
`B.
`
`The Petition’s Obviousness Grounds Are Redundant and Should
`Be Denied
`
`Concurrent with this Petition, in which Petitioner challenges claims 11-23
`
`and 25-30 of the ’0705 patent as obvious over Beser in view of RFC 2401, and
`
`claim 24 as obvious over Beser and RFC 2401in view of Brand, Petitioner also
`
`filed a petition for inter partes review in IPR2015-00871 (“the ’871 Petition”).
`
`The ’871 Petition challenges the same patent and the same claims, asserting two
`
`grounds of rejection, which simply substitute Beser with Aventail and RFC 2453.
`
`The Petition fails to assert or explain why the proposed grounds in the Petition are
`
`not redundant of the grounds in the ’871 Petition. Instead, the Petition contends,
`
`without explanation, that each Petition presents “non-redundant grounds.” (Pet. at
`
`2.) Given the Board’s jurisprudence regarding redundancy, Petitioner’s redundant
`
`grounds should be rejected.
`
`Redundant grounds place a significant burden on the Board and the patent
`
`owner, and cause unnecessary delay that jeopardizes meeting the statutory deadline
`
`for final written decisions. Liberty Mut. Ins. Co. v. Progressive Cas. Ins. Co.,
`
`CBM2012-00003, Paper No. 7 at 2 (Oct. 25, 2012). The consideration of
`
`redundant grounds frustrates Congress’s intent that the Board “secure the just,
`
`speedy, and inexpensive resolution of every proceeding,” in violation of 37 C.F.R.
`
`§ 42.1(b).
`
`
`
`10
`
`
`
`
`
`Case No. IPR2015-00870
`
`The Board explains that where multiple grounds of rejection are presented,
`
`the “[d]ifferences between the claimed invention and the prior art are a critically
`
`important underlying factual inquiry . . . .” Liberty Mut. Ins. Co., CBM2012-
`
`00003, Paper No. 7 at 2-3. The redundancy inquiry does not focus on “whether the
`
`applied prior art disclosures have differences, for it is rarely the case that the
`
`disclosures of different prior art references, will be literally identical. EMC Corp.
`
`v. Personal Web Techs., LLC, IPR2013-00087, Paper No. 25 at 3 (June 5, 2013).
`
`Rather, the Board considers “whether the petitioner articulated a meaningful
`
`distinction in terms of relatives strengths and weaknesses with respect to
`
`application of the prior art disclosures to one or more claim limitations.” Id. at 3-4.
`
`The Petitioner carries the burden of articulating that “meaningful distinction.”
`
`ScentAir Techs., IPR2013-00180, Paper No. 18 at 3. Put simply, “[t]o avoid a
`
`holding of redundancy, the Petition has to explain why one reference is better in
`
`one respect but worse in another respect.” Toyota Motor Corp. v. Am. Vehicular
`
`Sciences LLC, IPR2013-00421, Paper No. 15 at 29 (Jan. 13, 2014).
`
`Petitioner’s burden of articulating a distinction between its redundant
`
`grounds is not lessened or removed simply because those grounds may appear in
`
`more than one petition. In fact, the policy considerations behind denying
`
`redundant grounds are even more compelling when those grounds are presented
`
`across multiple petitions. Multiple petitions necessitate multiple written decisions
`
`
`
`11
`
`
`
`
`and an analysis of a corresponding number of briefs, as well as the potential for
`
`Case No. IPR2015-00870
`
`differing panels of judges, multiple scheduling conferences, and multiple oral
`
`arguments—all of which tax the Board’s resources and diminish its ability to
`
`ensure the speedy resolution of each proceeding. Moreover the Board has
`
`previously recognized grounds as being redundant across petitions and dismissed
`
`the redundant grounds. See Apple Inc. v. VirnetX Inc., IPR2014-00483, Paper No.
`
`11 at 6 (Sept. 15, 2014).
`
`In Liberty Mutual, the Board identified two types of redundant rejections:
`
`(1) “horizontally” redundant rejections and (2) “vertically” redundant rejections.
`
`Liberty Mut. Ins. Co., CBM2012-00003, Paper No. 7 at 3. The Board explained
`
`that horizontally redundant rejections apply “a plurality of prior art references . . .
`
`not in combination to complement each other but as distinct and separate
`
`alternatives.” Id. Vertical redundancy “exists when there is assertion of an
`
`additional prior art reference to support another ground of unpatentability when a
`
`base ground already has been asserted against the same claim without the
`
`additional reference and the Petitioner has not explained what are the relative
`
`strength and weakness of each ground.” Id. at 12.
`
`Here, the Petition is horizontally redundant in view of the ’871 Petition. In
`
`both petitions, Petitioner alleges that claims 1-23 and 25-30 are rendered obvious
`
`based on a combination of RFC 2401 and either Beser or Aventail and RFC 2543.
`
`
`
`12
`
`
`
`
`Both petitions also allege that claim 24 is rendered obvious based on a combination
`
`Case No. IPR2015-00870
`
`of RFC 2401 and Brand with either Beser or Aventail and RFC 2543. These
`
`grounds are horizontally redundant and Petitioner fails to provide any explanation
`
`to the contrary.
`
`In the instant Petition, Petitioner relies on RFC 2401, in conjunction with
`
`Beser, for the claimed limitations, including the claimed “secure communication
`
`link.” (Pet. at 34-42.) According to the Petition, one skilled in the art would have
`
`encrypted the tunneling associations taught in Beser in light of RFC 2401. (Id. at
`
`26-33.) Similarly, in the ’871 Petition, Petitioner again relies on RFC 2401, this
`
`time in conjunction with Aventail and RFC 2543, for the claimed “secure
`
`communication link.” Attempting to address redundancy, Petitioner claims its
`
`grounds are “non-redundant” because each petition “present[s] unique correlations
`
`of the challenged ’0705 claims to the prior art.” (Pet. at 2.) But, as the Board has
`
`explained, a redundancy analysis does not focus on whether the prior art references
`
`are identical. EMC Corp., IPR2013-00087, Paper No. 25 at 3. And Petitioner does
`
`not attempt to “articulate[] a meaningful distinction in terms of relative strengths
`
`and weaknesses with respect to application of the prior art disclosures to one or
`
`more claim limitations.” Id. at 3-4 (emphasis added). Consequently, the Board
`
`should deny Petitioner’s redundant grounds.

`
`
`
`
`Case No. IPR2015-00870
`
`C. The Petition Fails to Show a Reasonable Likelihood That
`Petitioner Will Prevail With Respect to Any Claim
`
`Petitioner proposes that claims 1-23 and 25-30 would be rendered obvious
`
`under 35 U.S.C. § 103 based on Beser in view of RFC 2401 and that claim 24
`
`would be rendered obvious under 35 U.S.C. § 103 based on Beser in view of RFC
`
`2401 and Brand. Obviousness is a question of law based on underlying factual
`
`findings, including: (1) the scope and content of the prior art; (2) the differences
`
`between the claims and the prior art; (3) the level of ordinary skill in the art; and
`
`(4) objective indicia of nonobviousness. Graham v. John Deere Co. of Kansas
`
`City, 383 U.S. 1, 17-18 (1966). Each of these factors should be considered in an
`
`obviousness analysis. In re Cyclobenzaprine Hydrochloride Extended-Release
`
`Capsule Patent Litig., 676 F.3d 1063, 1075, 1077, 1080 (Fed. Cir. 2012). In
`
`particular, “[i]t is not sufficient to demonstrate that each of the components
