      “Both parties maintain that no claim term needs to be construed. Pet. 4 (citing Ex. 1003 ¶ 40); PO Resp. 20. Patent Owner, however, provides an express construction for limitation [1.d] of independent claim 1 and the similar limitation of independent claim 13, namely limitation [13.c]. PO Resp. 20 (citing Ex. 2011 ¶ 25). To resolve the controversy before us, we determine that these limitations require express construction. 1. “the glass element is configured to propagate and modify a stress wave to the coating/substrate interface to generate a tensile stress between the substrate and the coating” (limitation [1.d]) and “propagating and modifying a stress wave through the glass element to the coating/substrate interface to generate a tensile force between the substrate and the coating” (limitation [13.c]) Patent Owner argues these limitations mean “changing the profile of the laser generated compressive wave and propagating the wave profile as modified to the free surface of the coating, which upon reflection from the free surface as a tension wave generates a tensile stress at the coating/substrate interface.” PO Resp. 20 (citing Ex. 2011 ¶ 25). Petitioner does not refute this proposed construction and, during the oral argument, Petitioner confirmed it agrees with the proposed construction. Tr. 8:16–9:12. We so no reason to depart from the parties agreed-upon construction of limitations [1.d] and [13.c].

      “a shock in the compression wave in the fused silica substrate. Even if we were to agree with Petitioner that Wang-Dissertation’s fused silica substrate modifies the compression waveform, we would not be persuaded that the fused silica substrate propagates the modified wave to the free surface of the coating, which upon reflection from the free surface as a tension wave generates a tensile stress at the coating/substrate interface, as limitation [1.d] requires. In view of the presence of tension-wave-1 in Wang-Dissertation’s experiments, we find Petitioner has not demonstrated persuasively that the fused silica substrate propagates a modified stress wave to the free surface of the coating to generate a tensile stress at the coating/substrate interface. Also, we find credible Dr. Gupta’s unrebutted testimony that any modified compression wave would attenuate in the substrate and not propagate to the free surface coating or generate a tensile stress at the coating/substrate interface. Ex. 2011 ¶¶ 93–98. Petitioner does not dispute that the experiments in Wang-Dissertation include tension-wave-1. See Ex. 1005, 65 (“The experimental picture is complicated somewhat by the presence of a tensile wave, reflected from the back of the confining layer.”). Nor does Petitioner dispute that Wang-Dissertation discloses that the tension-wave-1 propagates faster than the compression-wave-1 and eventually overtakes compression-wave-1. See id. at 65–66 (“Being tensile, it propagates faster that the peak compressive stress, and faster than the low stress tail of the main pulse. It eventually overtakes the compressive pulse and linear dissipative mechanisms govern the final thickness of the shock.”). Rather, Petitioner relies on Dr. Wang’s testimony regarding the timing of the waves through the sample and argues that tension-wave-1 does not overtake compression-wave-1 in the fused silica substrate. Pet. Reply 17 (citing Ex. 1038 ¶ 5). Dr. Wang testifies that the peak stress from tension-wave-1 is about 2 ns behind the peak of compression-wave-1 and will not reach the interface before the reflected tensile peak of compression-wave-1 reaches the interface in 0.3 ns. Ex. 1038 ¶ 5. However, as Dr. Gupta persuasively explains, the delay between tension-wave-1 and compression-wave-1 depends on the properties of the confining layer, and Wang-Dissertation acknowledges that these properties are not well controlled. Ex. 2011 ¶ 54; see also Ex. 1005, 65 (“The surface properties of that confining layer are not well controlled.”).” slip op. at 19

      “These deficiencies in analysis raise the question of whether the Petition adequately identifies the number of actual challenges, and evidence supporting each, with the degree of particularity required of petitions in our forum.

See generally Pet.

      “We agree with Patent Owner that claim 15 requires modifying the first instruction set before determining the modified first instruction set based on an at least partial match between the new digital picture and the first digital picture. Claim 15 recites “modifying: the first one or more instruction sets” and “determining the modified the first one or more instruction sets . . . based on the at least partial match between the new one or more digital pictures and the first one or more digital pictures.” Ex. 1001, 162:65–163:15 (emphasis added). The phrase “the modified . . . instruction sets” in the determining limitation indicates an order because it refers back to the instruction sets modified in the modifying limitation. Id. Further, the phrase “based on the at least partial match” indicates that a partial match between the new picture and the first picture returns the modified first instruction set. Id. In order for a partial match to return the modified first instruction set, it is logical that the first instruction set previously was modified and correlated to the first picture. Id. Thus, claim 15 indicates that the modifying limitation is performed before the determining limitation. See Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369 (Fed.

In other words, according to Patent Owner, Petitioner “failed to perform a proper obviousness analysis because Petitioner has failed to identify anything in the claims that Buibas lacks disclosure of for Ground 1A.” Id. at 20. Based on the present record, we determine that Petitioner has set forth sufficient reasoning to support a motivation to combine Buibas and Sinyavskiy for purposes of institution, as well as sufficient reasoning to support the conclusion that one of ordinary skill would have had a reasonable expectation of success in making the combination. We do not agree with Patent Owner’s argument that Petitioner’s obviousness analysis is flawed because it fails to identify what is lacking in Buibas’s disclosure. To the contrary, Petitioner explains that Buibas “broadly suggests” that its spiking neural networks “can be partitioned into modules for different tasks or behaviors” but “discloses little detail about the partitioning,” and that Sinyavskiy’s more detailed disclosure of partitioning spiking neural networks would fill in these details. See Pet. 12–13, 14–15, 24. Petitioner also relies on Sinyavskiy’s more detailed disclosures concerning partitioning the network to satisfy limitations [45.1] and [45.6]. Id. at 23–27, 35.

      “On this record, we find that the above noted evidence comprises “evidence sufficient to establish a reasonable likelihood that the reference was publicly accessible before the critical date of the challenged patent and therefore that there is a reasonable likelihood that [Wang] qualifies as a printed publication.” Hulu, IPR2018-01039, Paper 29 at 13. Patent Owner raises a number of questions about Petitioner’s showing. First, Patent Owner contends that the Morris Declaration “is not credible or legally sufficient for various reasons,” including a lack of corroborating evidence. Prelim. Resp. 28–30 (citing, inter alia, Finnigan Corp. v. Int’l Trade Comm’n, 180 F.3d 1354, 1369 (Fed. Cir. 1999)). Nonetheless, Ms. Morris’s testimony at least is consistent with the indicators of publication appearing in the front matter of Wang. See Ex. 1005, 1, 3–6 (added page numbers). As such, we find Ms. Morris’s testimony sufficiently reliable to support a reasonable likelihood that Wang would qualify as a prior art printed publication. At trial, the parties can develop the record about whether, and, if so, the extent to which, testimony regarding publication by a non-inventor witness must be corroborated with other evidence.” slip op. at 15

      “f) Enablement of Wang In order for a prior art reference to anticipate a claim, that reference must enable a person of ordinary skill in the art to make the claimed subject matter. PPG Indus., Inc. v. Guardian Indus. Corp., 75 F.3d 1558, 1566 (Fed. Cir. 1996) (“To anticipate a claim, a reference must disclose every element of the challenged claim and enable one skilled in the art to make the anticipating subject matter.”) Enablement of a prior art reference does not require that the prior art reference show that the disclosed subject matter would have utility; that is, that it would work for any particular purpose. Rasmusson v. SmithKline Beecham Corp., 413 F.3d 1318, 1326 (Fed. Cir. 2005). (“[T]his court has continued to recognize that a prior art reference need not demonstrate utility in order to serve as an anticipating reference under section 102.”), In re Schoenwald, 964 F.2d 1122, 1124 (Fed. Cir. 1992) (“[I]t is beyond argument that no utility need be disclosed for a reference to be anticipatory.”) All that matters is whether the skilled person could have made the claimed subject matter, without undue experimentation. In re Antor Media Corp., 689 F.3d 1282, 1290 (Fed. Cir. 2012) (“Enablement of prior art requires that the reference teach a skilled artisan to make or carry out what it discloses in relation to the claimed invention.”) (emphasis added). Even references that disclose inoperative devices are still prior art for all that they teach. Id. (citing Beckman Instruments, Inc. v. LKB Produkter AB, 892 F.2d 1547, 1551 (Fed. Cir. 1989)). Therefore, questions of whether the prior art may teach away from making the claimed subject matter are not relevant to anticipation. Bristol-Myers Squibb Co. v. Ben Venue Lab’ys, Inc., 246 F.3d 1368, 1378 (Fed. Cir. 2001) (“Thus, the question whether a reference ‘teaches away’ from the invention is inapplicable to an anticipation analysis.”)” slip op. at 23

      “X. CONCLUSION For the reasons discussed above, we are persuaded that Petitioner has demonstrated a reasonable likelihood that it will succeed in showing that at least one of the challenged claims is unpatentable on the following challenges to patentability, including: Claims 1 and 5–8 as unpatentable over Li, Paunikar, and Wu. XI. ORDER In consideration of the foregoing, it is hereby: ORDERED that, pursuant to 35 U.S.C. § 314(a) an inter partes review of the ’845 patent is hereby instituted, commencing on the entry date of this Order, and pursuant to 35 U.S.C. § 314(c) and 37 C.F.R. § 42.4, notice is hereby given of the institution of a trial.” slip op. at 52

Patent Owner does not contest Petitioner’s description of an ordinarily skilled artisan. Prelim. Resp. 19. The level of ordinary skill in the art may be evidenced by the references themselves. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978).

      “On this record, Patent Owner’s argument is unavailing. First, the evidence of record indicates that Li and Wu are analogous art. Pet. 70; Ex. 1003, Bhattacharjee Decl. ¶ 201. For example, the ’845 patent, Li, and Wu are all directed to the same field of endeavor, namely, computer networking and routing data packets. Ex. 1001, 1:17–21, Ex. 1003 ¶ 201; Ex. 1037, 1; Ex. 1039, 9. Second, the evidence of record indicates that a person of ordinary skill in the art would have had a reasonable expectation of success in combining the cited teachings of Li and Wu. Pet. 78–79 (citing Ex. 1003, Bhattacharjee Decl. ¶ 207). As discussed above, Petitioner relies on Wu’s teaching that an IPv6 destination address includes a destination port number. Pet. 79–80 (citing Ex. 1003, Bhattacharjee Decl. ¶ 211). Even if Patent Owner is correct that Li and Wu address the interoperability of IPv4 and IPv6 networks from different perspectives, a person of ordinary skill in the art would have reasonably expected that Wu’s destination port number could be incorporated into the unused padding in Li’s IPv6 destination address. Pet. 76–80; Ex. 1003 ¶¶ 199–212. On this record, Petitioner shows sufficiently that an ordinarily skilled artisan would have had reason to combine the cited teachings of Li and Wu.” slip op. at 51

      “An inter partes review may not be instituted unless “the information presented in the petition . . . and any response . . . shows 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). Further, when instituting an inter partes review, we “will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” 37 C.F.R. § 42.108(a). Here, Petitioner demonstrates a reasonable likelihood of prevailing in showing that at least one of the challenged claims is unpatentable.

      “the same standard used in a civil action under 35 U.S.C. § 282(b), including construing the claim in accordance with the ordinary and customary meaning of the claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. 37 C.F.R. § 42.100(b). Petitioner notes that several claim terms previously were construed by a district court in another case. Pet. 10–14 (citing Ex. 1036). Patent Owner proposes construing the term “domain” to mean “a network or subnetwork and its address space that are under common control.” Prelim. Resp. 19–21. Petitioner disagrees with Patent Owner’s proposed construction of the term “domain.” Pet. 31. We determine that no claim terms require express construction for purposes of this Decision. As discussed below, even if we assume that the term “domain” means “a network or subnetwork and its address space that are under common control,” Petitioner shows sufficiently that at least one of the challenged claims is unpatentable. See Section II.E.1. As a result, we need not resolve the parties’ dispute about the meaning of the term “domain” for purposes of this Decision. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

      “As discussed above, Petitioner presents evidence that although Li-2 “never became an official Internet-Draft published in the IETF directory,” Li-2 remained in the IETF’s staging folder. Pet. 20–22; Ex. 1009 ¶¶ 10–11. But the evidence of record indicates that the IETF’s staging folder may contain thousands of documents. Prelim. Resp. 35; Ex. 1008 ¶ 4; Ex. 1044. This raises the issue of whether a person of ordinary skill in the art exercising reasonable diligence could have located Li-2 simply by browsing the filenames of the numerous documents in the IETF’s staging folder. Patent Owner may address this issue again and present any other arguments regarding this asserted ground in its Patent Owner Response. Petitioner also presents evidence that the IETF’s Datatracker included Li-2 for “a given period” after the authors canceled Li-2. Pet 22; Ex. 1008 ¶ 11. But Petitioner does not indicate how long the IETF’s Datatracker would have included Li-2 (e.g., hours, days, weeks, years). See Pet. 22; Prelim. Resp. 36; Ex. 1008 ¶ 11. This raises the issue of whether Li-2 was present in the IETF’s Datatracker such that a person of ordinary skill in the art exercising reasonable diligence could have located Li-2.
