`
`
`Case 6:21-cv-00569-ADA Document 149 Filed 01/12/23 Page 7 of 15
`
`
`Touchstream seeks to improperly estop Google from advancing its prior-art system
`
`invalidity theories that fall well outside the scope of the stipulation Google entered in the parallel
`
`IPRs. Google’s stipulation is limited to the boundaries of the IPR estoppel statute, 35 U.S.C.
`
`§ 315(e): grounds that Google “raised or reasonably could have raised” during the IPRs. Prior-
`
`art systems cannot be raised in an IPR. Indeed, “[t]he language of [35 U.S.C.] § 311(b) limits ‘the
`
`basis’ of any ‘ground’ in an inter partes review to ‘prior art consistent of patents and printed
`
`publications.’” Qualcomm Inc. v. Apple Inc., 24 F.4th 1367, 1374 (Fed. Cir. 2022). The Court
`
`should reject Touchstream’s attempt to expand the stipulated estoppel past its defined limits.
`
`I.
`
`FACTUAL BACKGROUND
`
`A.
`
`Relevant Procedural History
`
`On April 8, 2022, Google petitioned for IPR against each of Touchstream’s Asserted
`
`Patents. Exs. 1-3. Prior to institution, Google entered into a stipulation to eliminate any potential
`
`overlap between the IPRs and this pending district-court litigation. Dkt. 136-4; see also Dkt.
`
`136-3. Per that stipulation, entered in accordance with the Board’s precedential decision in Sotera
`
`Wireless, Inc. v. Masimo Corp., IPR2020-01054, 2020 WL 7049825, at *6-7 (P.T.A.B. Dec. 1,
`
`2020), Google agreed that, if the Board instituted the IPRs, Google would not pursue any invalidity
`
`ground in this litigation that Google “raised or reasonably could have raised” during the IPRs.
`
`Dkt. 136-4. The stipulation, in effect, prevents Google from raising any grounds that it would be
`
`statutorily estopped from pursuing under 35 U.S.C. § 315(e) had the Board issued a FWD.
`
`After review of Google’s three IPR petitions, and in light of the Sotera stipulation, the
`
`Board instituted IPR against each of the Asserted Patents, concluding Google established a
`
`reasonable likelihood that at least one of the challenged claims of each of the Asserted Patents was
`
`unpatentable. Exs. 4-6. The IPRs are ongoing.
`
`Google’s invalidity theories here are separate and distinct from the grounds it petitioned
`
`
`
`
`
`Case 6:21-cv-00569-ADA Document 149 Filed 01/12/23 Page 8 of 15
`
`
`for in the IPRs. Google’s district-court theories focus on prior-art systems that could not have been
`
`raised in the IPRs, even though they also include some patents or printed publications (including
`
`two that were offered as the basis for IPR) for obviousness combinations or as additional evidence
`
`of operation of one of the prior-art systems. See Ex. 7 at 7-11. Touchstream moves to exclude
`
`three such prior-art systems—Twonky, Boxee, and Zelfy Peel—claiming incorrectly that Google
`
`could have raised the prior-art systems in the IPRs because they “are just collections of documents
`
`that Google could have used . . . in its IPR petitions.” Dkt. 136 at 1.1 After narrowing its invalidity
`
`theories, see Dkt. 125, Google will assert only one of these prior-art systems for its invalidity
`
`theories—Twonky. See Ex. 10. Google intends to reference the Boxee and Zelfy Peel prior-art
`
`systems at trial to illustrate the background state of the art of the Asserted Patents.
`
`B.
`
`The Twonky System
`
`The Twonky System is a software suite comprising several interworking software packages
`
`developed by the company PacketVideo. Ex. 8 ¶ 111. PacketVideo designed the Twonky System
`
`to allow customers to access and control media across a network on various devices, including
`
`laptops, smartphones, and display devices. See id. ¶¶ 111-33. The Twonky System was available
`
`at least by March 31, 2009, well before Touchstream sought the Asserted Patents. See id. ¶ 111.
`
`To develop its invalidity theories concerning the Twonky System, Google sought out
`
`documentation reflecting its functionality and videos demonstrating its use. While some
`
`documentation, including patents and printed publications, was public, to fully understand the
`
`Twonky System’s functionality, Google sought confidential, internal documentation from
`
`PacketVideo. To do so, Google subpoenaed J.M. Driver LLC, the corporate successor to
`
`PacketVideo, and requested documents directly from former PacketVideo employees. See Dkt.
`
`
`1 Touchstream does not move to exclude the GTS prior-art system. See Dkt. 136.
`
`-2-
`
`
`
`Case 6:21-cv-00569-ADA Document 149 Filed 01/12/23 Page 9 of 15
`
`
`136-11 ¶ 2; Ex. 9. Ultimately, Google received documents, including non-public, confidential
`
`PacketVideo documents that explained critical functionality of the Twonky System, from former
`
`PacketVideo employee Rick Schwartz, who was a Senior Product Manager of the Twonky System.
`
`Dkt. 136-11 ¶ 2. Google produced these documents to Touchstream on October 13, 2022, prior to
`
`the close of fact discovery. These non-public documents play a central role in establishing that
`
`the Twonky System, in combination with other prior art, invalidates the Asserted Patents. Google
`
`also collected videos demonstrating its functionality. See Ex. 8 ¶ 111 (T-9); Dkt. 136-6.
`
`Google’s expert, Dr. Mayer-Patel, reviewed this material to opine as to why the Twonky
`
`System in combination with other prior-art references invalidates Touchstream’s Asserted Patents.
`
`Ex. 8 ¶¶ 2, 111. In his opening report, Dr. Mayer-Patel analyzed the non-public PacketVideo
`
`internal documents, including several marked confidential, and videos demonstrating the Twonky
`
`System’s functionality to reach his invalidity opinion. Id. ¶¶ 111 (listing Twonky System materials
`
`reviewed, including videos of product demonstrations and non-public and confidential
`
`documents). After review, Dr. Mayer-Patel opined on the invalidity of the Asserted Patents based
`
`on information available only in these non-public Twonky System documents. See, e.g., id.
`
`¶¶ 473, 482-83, 485-91, 507, 512, 530, 555, 576, 795.
`
`II.
`
`ARGUMENT
`
`Touchstream bears the burden to prove that estoppel should be applied. E.g., Clearlamp,
`
`LLC v. LKQ Corp., 2016 WL 4734389, at *9 (N.D. Ill. 2016); see also Tate v. Veolia Transp.
`
`Servs., Inc., 2010 WL 11598051, at *4 (W.D. Tex. 2010). Touchstream fails to meet that burden
`
`here. Given the Sotera stipulation, case law interpreting the scope of § 315(e) as it relates to prior-
`
`art systems guides the Court’s analysis, as Touchstream acknowledges, see Dkt. 136 at 4.

`
`
`A.
`
`Google’s Sotera Stipulation Does Not Estop Google From Asserting The
`Twonky System At Trial
`
`Touchstream improperly attempts to expand Google’s Sotera stipulation beyond its scope.
`
`Touchstream argues that “any invalidity contentions that purport to use the Twonky system in
`
`combination with other prior art in the form of patents and printed publications should . . . be
`
`excluded.” Dkt. 136 at 6. But as this Court has acknowledged in other circumstances, “[e]stoppel
`
`under § 315(e) is broad but would not foreclose [the defendant] from challenging the asserted claim
`
`using system prior art . . . —maybe even combined with prior art publications used in the IPRs.”
`
`Sonrai Memory Ltd. v. W. Digital Techs., Inc., 2022 WL 3108818, at *3 (W.D. Tex. 2022). As
`
`other courts have explained, “any invalidity theory relying upon [a] product as a prior art reference
`
`is not a ‘ground’ that reasonably could have been raised during [an] IPR.” Chermours Co. FC,
`
`LLC v. Daikin Indus. Ltd., 2022 WL 2643517, at *1-2 (D. Del. 2022) (quoting Medline Indus., Inc.
`
`v. C.R. Bard, Inc., 2020 WL 5512132, at *3 (N.D. Ill. 2020)). Numerous other courts have reached
`
`this same conclusion. See, e.g., IOENGINE, LLC v. PayPal Holdings, Inc., 2022 WL 2800861, at
`
`*31 (D. Del. 2022) (Bryson, J., sitting by designation) (“In general, IPR estoppel does not apply
`
`to device art, because ‘a petitioner cannot use an IPR to challenge the validity of a patent claim . . .
`
`based on prior art products or systems.’”); In re Koninklijke Philips Patent Litig., 2020 WL
`
`7392868, at *27 (N.D. Cal. 2020) (“IPR estoppel does not apply to [a defendant’s] product prior
`
`art grounds.”); Intell. Ventures II LLC v. Kemper Corp., 2016 WL 7634422, at *3 (E.D. Tex. 2016)
`
`(“[R]egardless of any estoppel, defendants have considerable latitude in using prior art systems . . .
`
`embodying the same patents or printed publications placed before the PTO in IPR proceedings.”).
`
`These courts have reached this conclusion after interpreting § 315(e), explaining that,
`
`“[a]lthough the Patent Act does not expressly define the term ‘ground,’ . . . courts have interpreted
`
`this term in the IPR estoppel context to mean the ‘specific pieces of prior art’ that are ‘the basis or
`
`-4-
`
`
`
`Case 6:21-cv-00569-ADA Document 149 Filed 01/12/23 Page 11 of 15
`
`
`bases on which a petitioner challenges a claim.’” Chemours, 2022 WL 2643517, at *1 (quoting
`
`Medline, 2020 WL 5512132, at *3). And this line of decisions emphasize that “Congress could
`
`have dictated that estoppel applies to products covered by the paper art underlying the IPR where
`
`the paper art discloses the same claim limitations as the product. But Congress did not do so.” Id.
`
`at *2; Medline, 2020 WL 5512132, at *4 (same). Because prior art systems are outside of the
`
`scope of § 315(e) estoppel—even if based on functionality outlined in other printed prior art—
`
`estoppel does not prevent Google’s use of the Twonky System for invalidity purposes here.
`
`There is also no basis to prevent Google from relying on documents describing a prior-art
`
`system’s functionality rather than the product itself. Contra Dkt. 136 at 6. Courts “have allowed
`
`the functions of prior art devices to be established through the use of documents and testimony.”
`
`IOENGINE, 2022 WL 2800861, at *31. That is because “documentation is evidence of how the
`
`product is configured, how it is made, and how it works,” and it is thus permissible for an expert
`
`to have “relied on documentation describing the product” to understand it. SiOnyx, LLC v.
`
`Hamamatsu Photonics K.K., 330 F. Supp. 3d 574, 604 (D. Mass 2018). Indeed, the Federal Circuit
`
`has explained that materials other than the physical prior-art system itself are suitable for
`
`describing a prior-art system’s functionality. E.g., Sonoscan, Inc. v. Sonotek, Inc., 936 F.2d 1261,
`
`1263 (Fed. Cir. 1991) (under § 102(b) “the offered product is in fact the claimed invention may be
`
`established by any relevant evidence, such as memoranda, drawings, correspondence, and
`
`testimony of witnesses”).
`
`Even if the Court were to adopt Touchstream’s view of estoppel (it should not), courts
`
`applying that view have explained that “reliance on some printed publications in an overall
`
`collection of documents being used to describe a system invalidity theory should not lead to
`
`estoppel of the overall system invalidity theory itself, nor piecemeal exclusion of the printed
`
`-5-
`
`
`
`Case 6:21-cv-00569-ADA Document 149 Filed 01/12/23 Page 12 of 15
`
`
`publications underlying that system invalidity theory, absent a showing that the system invalidity
`
`theory is a patent or printed publication theory in disguise.” SPEX Techs. Inc. v. Kingston Tech.
`
`Corp., 2020 WL 4342254, at *15 (C.D. Cal. 2020). Touchstream fails to meet its burden to show
`
`why estoppel should apply to Google’s invalidity theories and Dr. Mayer-Patel’s expert report
`
`based on Twonky—which, as explained above, depend on non-public, confidential documents
`
`from PacketVideo and thus could not have been reasonably relied upon in the IPRs. Under similar
`
`circumstances, courts have refused to apply estoppel that would have prevented the use of asserted
`
`prior-art systems for invalidity purposes. See, e.g., IOENGINE, 2022 WL 2800861, at *31
`
`(declining to apply estoppel because “IOENGINE’s briefing address the general categories of
`
`documents on which Ingenico seeks to rely, but it does not address Ingenico’s assertion that some
`
`of those documents would not have been publicly available and could not reasonably have been
`
`relied upon in an IPR proceeding”); SPEX, 2020 WL 4342254, at *15 (same). Indeed, even
`
`Touchstream’s cited cases required a showing that the asserted prior-art systems relied exclusively
`
`on public documentation for estoppel to apply. Gen. Access Sols., Ltd. v. Sprint Spectrum LLC,
`
`2020 WL 12572917, at *3-4 (E.D. Tex. 2020) (explaining that defendant’s prior-art system should
`
`be excluded if defendant “is using its system prior art as a Trojan horse for printed subject matter”);
`
`Avanos Med. Sales, LLC v. Medtronic Sofamore Danek USA, Inc., 2021 WL 8693677, at *2 (W.D.
`
`Tenn. 2021) (granting estoppel because patentee showed information from confidential materials
`
`were duplicative of publicly available documentation). Touchstream has made no such showing
`
`here, nor could it.
`
`Touchstream argues that the Declaration of Rick Schwartz should be excluded because
`
`Google did not produce it until after the close of fact discovery and that, as a result, the non-public
`
`Twonky documents are inadmissible. See Dkt. 136, at 5-6. Both arguments are meritless. Google
`
`-6-
`
`
`
`Case 6:21-cv-00569-ADA Document 149 Filed 01/12/23 Page 13 of 15
`
`
`produced the Twonky documents on October 13, 2022, prior to the close of fact discovery. See
`
`Dkt. 92 at 1. There are thus no grounds to exclude the documents under Touchstream’s late-
`
`disclosure theory. As to the Schwartz Declaration, Touchstream’s argument misunderstands the
`
`purpose of the Declaration. Google does not intend to seek testimony from Schwartz at trial or to
`
`admit his Declaration into evidence. The Schwartz Declaration simply provided Dr. Mayer-Patel
`
`with context of the timely produced public and non-public Twonky documents received from
`
`Schwartz, a former employee of PacketVideo. The referenced documents were produced during
`
`discovery in this case and available to both parties. Dr. Mayer-Patel is entitled to rely on such
`
`information to reach his expert opinion under Fed. R. Evid. 703. See Factory Mut. Ins. Co. v. Alon
`
`USA L.P., 705 F.3d 518, 523-24 (5th Cir. 2013) (“If the facts and data relied upon are the sort that
`
`experts in that field would reasonably rely on, then those facts ‘need not be admissible for the
`
`opinion to be admitted.’”). The parties are thus equally situated, and there is no prejudice to
`
`Touchstream in Dr. Mayer-Patel’s review of the Schwartz Declaration.
`
`B.
`
`The Boxee and Zelfy Peel Systems Are Admissible At Trial As Examples Of
`The Background State Of The Art And Are Admissible For Other Invalidity
`And Damages Purposes
`
`Touchstream argues that the Boxee and Zelfy Peel Systems should be excluded under
`
`Google’s Sotera stipulation because they “are based entirely on patents and printed publications
`
`that were publically [sic] available.” Dkt. 136 at 4. But Google is no longer relying on the Boxee
`
`or Zelfy Peel Systems as prior art for an invalidity theory. See Ex. 10. Accordingly,
`
`Touchstream’s motion as to Boxee and Zelfy Peel is moot. To the extent Touchstream’s challenge
`
`expands to Google’s use of Boxee and Zelfy Peel for any prior-art purpose, Touchstream’s motion
`
`should be denied because it is appropriate for Google to rely on prior art such as the Boxee and
`
`Zelfy Peel Systems as evidence of the background state of the art. As the Federal Circuit has
`
`explained, “[r]egardless of the tribunal, the inquiry into whether any ‘differences’ between the

`
`
`invention and the prior would have rendered the invention obvious to a skilled artisan necessarily
`
`depends on such artisan’s knowledge.” Koninklijke Philips N.V. v. Google LLC, 948 F.3d 1330,
`
`1337 (Fed. Cir. 2020). Likewise, the Boxee and Zelfy Peel Systems are appropriate prior-art
`
`evidence countering Touchstream’s purported evidence of secondary considerations of
`
`nonobviousness, see, e.g., Apple Inc. v. Samsung Elecs. Co., 839 F.3d 1034, 1056 (Fed. Cir. 2016)
`
`(en banc) (prior-art evidence relevant to the fact finder’s evaluation of secondary considerations
`
`of nonobviousness), and as evidence of available non-infringing alternatives for damages
`
`purposes, see, e.g., Exmark Mfg. Co. v. Briggs & Stratton Power Prods. Grp., LLC, 879 F.3d 1332,
`
`1351-52 (Fed. Cir. 2018) (error to limit use of prior art for damages purposes).
`
`III. CONCLUSION
`
`For the foregoing reasons, the Court should deny Touchstream’s Motion to Exclude
`
`Portions of Defendant’s Invalidity Contentions and Expert Report, Dkt. 136.
