    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

      “We agree that Patent Owner’s proposed claim construction is wholly unsupported by, and inconsistent with, the language of independent claims 1, 7, and 13, and the aims of the ’670 Patent Specification. See Ex. 1001, 2:3– 25, 9:32–10:5, 12:51–67, 18:54–19:6, 19:26–42, 20:12–26. Moreover, the cited extrinsic evidence––testimony by Patent Owner’s expert Dr. Lomp–– does not support Patent Owner’s proposed construction because it is internally inconsistent and also undermined by Dr. Lomp’s inconsistent deposition testimony. See Ex. 1036, 11:6–17, 12:9–12; Ex. 2010 ¶¶ 40, 48. Similarly, the extrinsic evidence cited by Petitioner (e.g., Exs. 1037, 1038, 2009) undermines Patent Owner’s position emphasizing the intended recipient devices of SIB1. In summary, we decline to adopt Patent Owner’s proposed claim construction because it is unsupported by the claim language, the ’670 Patent Specification, and the cited extrinsic evidence. with the ordinary and customary meaning which does not include limiting SIB1 to an ordinary legacy SIB and excluding MTC specific SIBs or SIBs intended for MTC devices. In addition, we need not construe explicitly any other claim term or phrase. See, e.g., Nidec Motor Corp. 868 F.3d at 1017 (“[W]e need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v.

      “would have had a bachelor’s degree from an accredited program in electrical engineering, computer engineering, computer science, or equivalent training, and at least two years of professional experience relating to wireless communication technology” and “[l]ack of professional experience can be remedied by additional education, and vice versa.” Pet. 15–16 (citing Ex. 1003 ¶¶ 19–21). Patent Owner does not dispute Petitioner’s definition. See generally PO Resp. We find that “at least” in Petitioner’s formulation of the level of skill in the art is vague and open-ended. Otherwise, we adopt Petitioner’s definition of a person of ordinary skill in the art because it is consistent with the level of skill reflected by the ’670 Patent Specification and the prior art of record. slip op. at 14

    • Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner

      “filing date. As explained above, the burden of production shifted to Patent Owner to show that Wallen is not prior art because the ’670 Patent is entitled to the earlier January 20, 2012, filing date of foreign priority application GB1201000. See Dynamic Drinkware, 800 F.3d at 1379–1380. For a claim in a later-filed application to be entitled to the filing date of an earlier application, the earlier application must provide written description support for the claimed subject matter. Anascape, Ltd. v. Nintendo of Am. Inc., 601 F.3d 1333, 1337 (Fed. Cir. 2010). To satisfy the written description requirement, “a prior application itself must describe an invention, and do so in sufficient detail that one skilled in the art can clearly conclude that the inventor invented the claimed invention as of the filing date sought.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 1997); see also VasCath v. Mahurkar, 935 F.2d 1555, 1563–64 (Fed. Cir. 1991) (“[T]he applicant must . . . convey with reasonable clarity to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention . . . now claimed.” (emphasis omitted)), Ariad Pharm. Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1352 (Fed. Cir. 2010) (en banc) (“[I]t is the specification itself that must demonstrate possession.”). Patent Owner’s arguments fail to meet this burden of production because, aside from addressing a system information block 1, Patent Owner’s arguments do not substantively address how GB1201000 provides written description support for any other limitations of the claimed invention. See PO Resp. 43, 57. Accordingly, Patent Owner has not met its burden of production in coming forward with evidence or argument to show possession of the claimed invention in foreign priority application GB1201000, the burden of production did not shift back to Petitioner, and,” slip op. at 18

      “primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) including a master information block (MIB).” See Pet. 41–42 (citing Ex. 1003 ¶¶ 70–75; Ex. 1005 ¶¶ 76, 77, 83–84). Petitioner implicitly acknowledges that Wallen does not expressly disclose a physical broadcast channel (PBCH), but relies on Berggren for confirming that the LTE standard specifies that a PBCH carries the MIB. See Pet. 42–43 (citing Ex. 1003 ¶ 74; Ex. 1007 ¶¶ 73–75). According to Petitioner, “a person of ordinary skill in the art would have been motivated to transmit Wallen’s MIB using a PBCH as taught by Berggren.” Pet. 43 (citing Pet. 33–38). In particular, Petitioner asserts that a person of ordinary skill in the art “would have been motivated for Wallen’s LTE system to utilize the LTE standard implementation details taught by Berggren,” and “it would have been predictable and beneficial for Wallen’s user equipment to receive the MIB in the [PBCH], as was standard in LTE.” Pet. 34 (citing Ex. 1003 ¶ 58), 37 (citing Ex. 1003 ¶ 63). According to Petitioner, “the combination is nothing more than ‘the predictable use of prior art elements according to their established functions.’” Pet. 38 (citing KSR, 550 U.S. at 417). Based on the entire record developed during trial, we are persuaded by a preponderance of the evidence that Petitioner provides sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to a person of ordinary skill in the art to modify Wallen’s broadcast MIB with Berggren’s teachings of using a PBCH for transmitting broadcast MIBs. See Pet. 33–38; KSR, 550 U.S. at 418.” slip op. at 24

    • PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Denied

      “We determine below that Fintiv factors 1–5 do not favor discretionary denial. Thus, we do not reach the issue of whether the merits are compelling. CommScope Techs. LLC v. Dali Wireless, Inc., IPR2022- 01242, Paper 23 at 4–5 (PTAB Feb. 27, 2023) (precedential) (Board must first address Fintiv factors 1–5, and should engage the compelling merits question only if that analysis favors discretionary denial) (“CommScope”). 7. Balancing the Fintiv Factors Weighing against exercising our discretion to deny institution is factor 3 involving the parties’ limited investment and lack of substantive orders in the District Court litigation. Factor 4 concerning the limited overlap of the issues in the two cases also weighs against discretionary denial. Only factor 5, that Petitioner and the defendant in the District Court litigation are the same party, weighs in favor of discretionary denial. Factor 1 concerning the absence of a stay in the District Court litigation, and factor 2 concerning the close proximity between the start of trial in the District Court litigation and the estimated deadline for the final written decision, are neutral on the facts of this case. We therefore determine that the balance of factors 1–5 weighs against discretionary denial. Accordingly, we do not consider the issue of whether compelling merits have been shown under factor 6.

    • Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner

      “Pet. 9 (citing Ex. 1006, 23) (emphasis added). From this passage, we understand the “safety” switch to be “separate” from the panic button, not a part of it. This understanding is reinforced by claim 7 which depends from claim 1 and recites that the mobile device “further compris[es] a safety switch,” meaning it is a separate element from the panic button. Ex. 1001, 9:3–4. Thus, moving the safety switch into position readies the panic button, which is not the same as the panic button readying itself to perform functions in claims 1–8 of the ’404 patent. Patent Owner does not sufficiently address this issue in its assertions. See Prelim. Resp. 5–7. Patent Owner’s reliance on disclosures elsewhere in the ’404 patent is likewise not persuasive. Prelim. Resp. 5–6. For example, the ’353 application mentions “ready” in relation to using a self-defense mechanism such as pepper spray, which has not been shown to be related to the panic button. Ex. 1006, 5, 9–10. Although Patent Owner relies on the ’353 application’s description of voice activation using a codeword, voice activation does not ready the panic button for activation to perform functions, but actually activates the panic button to perform those functions. Prelim. Resp. 6 (citing Ex. 1006, 17). Petitioner thus met its burden here to demonstrate that claims 1–8 of the ’404 patent lack written description support for a panic button adapted to “ready itself” to perform the recited functions because the limitation is not present in the ’353 application to which the ’404 patent claims priority. Pet. 8–10. The burden of production thus shifted to Patent Owner to demonstrate that the ’353 application has written description support for this limitation, which it has not done on this record.

      “of the proceeding, we are persuaded that Petitioner has demonstrated a reasonable likelihood of prevailing on its assertions that at least one of claims 1–8 of the ’404 patent would have been obvious under 35 U.S.C. § 103 based on the ground set forth in the Petition. Accordingly, we institute trial for all challenged claims on all grounds asserted by Petitioner. See SAS Institute Inc. v. Iancu, 138 S. Ct. 1348 (2018).

      “Petitioner has shown sufficiently that a POSITA would have combined DiPerna964 and Strack with a reasonable expectation of success. Pet. 16–18. DiPerna964 and Strack are directed to similar mobile devices for use in security and emergency situations. Id. at 16–17. Petitioner demonstrates sufficiently that a POSITA would have regarded Strack’s arming and timer technique as an improvement that would have been useful with DiPerna964’s mobile device (at least in some circumstances) to provide the user with additional time to evaluate whether triggering the 911 call is warranted. Id. at 17–18. This amounts to the use of a known technique to improve similar devices in the same way, which is a recognized rationale for combining prior art references. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 401, 417 (2007).

We are also persuaded that Oksala’s disclosure would have motivated a person of ordinary skill in the art to modify Oksala, as Petitioner contends, to yield the subject matter of claim 1.

Indefiniteness In its Opposition, Petitioner contends the limitations “wherein each established data connection is a packet-switched connection; and wherein each requested data connection is a packet-switched connection,” as recited in substitute claim 26, and similarly recited in substitute claims 35 and 43, render the proposed substitute claims indefinite. MTA Opp. 12 (emphases added). First, according to Petitioner, the term “packet-switched connection” does not have a claim construction, which means that it can refer to two different types of packet-switched data (i.e., Layer 1 and packet network). Id. at 12. Second, Petitioner contends that there are two recitations of “a packet-switched connection,” making it “unclear if they are the same packet-switched connection or a different one.” Id. at 12–13.

      “Obviousness Analysis A claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which the subject matter pertains. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations, primarily: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of nonobviousness.

Patent Owner does not address this issue in the Preliminary Response.

      “mental steps that an ordinarily skilled artisan theoretically might have taken after reviewing the minimal disclosure in the ’423 patent. The ’423 patent does not discuss any properties of metal oxides (other than the lower barrier of the metal oxide TiO2) or design considerations concerning the selection of particular oxides to use in the claimed structure, particularly in the context of MIGS separation. Dr. Kuhn cites very little, if any, evidence to support her testimony regarding the knowledge of an ordinarily skilled artisan. Thus, we do not credit this analysis as showing that an ordinarily skilled artisan would have found that the inventors of the pre-2011 priority applications possessed the recited genus.

      “Petitioner asserts that a person of ordinary skill in the art at the time of the invention “would have a degree in electrical engineering or similar discipline, with at least three years of relevant industry or research experience in telecommunication, including familiarity with cellular communications technologies,” that this person “would also have familiarity with WCDMA,” and that “[t]his definition is approximate,” as “more education may substitute for industry experience or vice versa.” Pet. 12–13 (citing Ex. 1007 ¶¶ 30–34). We adopted Petitioner’s proposal at institution. See Decision 7–8. In its Response, Patent Owner “proposes that a person having ordinary skill at the time of invention—August 23, 2005—in the relevant art would be one with a bachelor’s degree in electrical engineering, computer sciences, or telecommunications, along with three to five or more years of practical experience in the field” and that “[a] combination of more experience in the field and less education or more education and less experience in the field would also suffice.” PO Resp. 8 (citing Ex. 2001 ¶ 27). Patent Owner asserts that “[a]lthough [its] proposed level of skill in the art is similar to Petitioners’ proposal, Patent Owner includes the qualification that a combination of more experience in the field and less education, or more education and less experience in the field would also suffice.” Id. The parties do not argue that the formulation of the level of skill in the art affects any issue in this case, and we maintain our adoption of Petitioner’s formulation, which we find to be generally consistent with the disclosures of the ’443 patent and the prior art, and which includes that “more education may substitute for industry experience or vice versa.”” slip op. at 9

      “length indicator” to mean “a single length indicator that provides two pieces of information: (1) that a first data octet of the protocol data unit is a first octet of a first service data unit; and (2) that at least one other octet of the protocol data unit is the last octet of another service data unit.” See Prelim. Resp. 9–10. We agreed with Patent Owner that the specification’s description of a single length indicator that conveys both types of information and the arguments made during prosecution that the claims required a “single LI” or “the same length indicator” to include both types of information were sufficient to support a construction that required a single length indicator to include both pieces of information. See Decision 9. Although it did not propose a construction in the Petition, Petitioner now argues that “the claim language uses the indefinite article ‘a’ to modify ‘length indicator’” and that “[p]recedent is well settled that ‘an indefinite article ‘a’ or ‘an’ in patent parlance carries the meaning of ‘one or more’ in open-ended claims containing the transitional phrase ‘comprising.’” Pet. Reply 5 (citing KCJ Corp. v. Kinetic Concepts, Inc., 223 F.3d 1351, 1356 (Fed. Cir. 2000)). While we agree with Petitioner that “a” may mean “one or more,” that simply means that the addition of more length indicators would not be excluded from the scope of the claim. Petitioner does not explain, and we do not see, how that affects the meaning of “length indicator” itself and, for the reasons argued by Patent Owner and adopted at institution, we maintain the earlier construction of “length indicator” as “a single length indicator that provides two pieces of information: (1) that a first data octet of the protocol data unit is a first octet of a first service data unit; and (2) that at least one other octet of the protocol data unit is the last octet of another service data unit.” See Decision 8; Prelim.

      “We also observe that, although Patent Owner characterizes this issue as one based on “teaching away” (see, e.g., PO Resp. 3; PO Sur-Reply 15– 16), the argument is not about teaching away because Patent Owner is not pointing us to any specific teaching in the prior art, or elsewhere, that would counsel against the proposed modification. Patent Owner is not arguing that something in the prior art disparages or discourages the use of one bit of an LI as a flag. Instead, Patent Owner is arguing that one of skill in the art would not pursue the Qualcomm approach because to do so would mean accepting other drawbacks that would flow from the use of the flag. In any event, we credit Patent Owner’s evidence that dedicating a bit of the LI for use as a flag would reduce the length that could be represented by the remaining bits of the LI and cause SDUs to be divided into more PDUs. See, e.g., Ex. 2005 ¶¶ 30, 32. However, the record also shows that use of the flag would provide a specific advantage, as described in Qualcomm. See Ex. 1006, 3; Ex. 1007 ¶ 253. This is the motivation advanced by Petitioner which, notably, Patent Owner does not dispute. We conclude that, even if Patent Owner is correct that the proposal in Qualcomm would reduce the permitted PDU size from 128 octets to 64, the change would merely be something a skilled artisan would need to weigh against the advantages that the Qualcomm technique would provide. Patent Owner may be correct that the reduced lengths would, in the end, render the modified system unsuitable for certain applications or for adoption in a standard. That would not, however, make the modification nonobvious, particularly where the exact change proposed in the combination was suggested by individuals working in the field, as evidenced by Qualcomm itself.7 The record shows that at least some of those working in the field, at the time of the invention, believed that the advantages of Qualcomm’s approach would outweigh the reduced lengths.” slip op. at 20

    • BurdenMixed

      “In TS25.322, the value “0000000” is a predefined, special value used to indicate that “[t]he previous RLC PDU was exactly filled with the last segment of an RLC SDU and there is no ‘Length Indicator’ that indicates the end of the RLC SDU in the previous RLC PDU.” See Ex. 1005, 36–37. However, although Qualcomm specifically contemplates implementing its flag scheme by “[r]e-arrang[ing] special LI values as they are now coded on less number of bits” (Ex. 1006, 4), the Petition did not argue a combination that includes modification of the special LIs for the independent claims. Instead, Petitioner relied on Qualcomm’s proposal to modify ordinary LIs that indicate the end of SDUs. See, e.g., Pet. 71–72 (describing and illustrating modification of the LI that identified the end of SDU 1: “[t]he green modified LI indicates that a first data octet of PDU is a first octet of SDU1 and another octet of the PDU is the last octet of SDU1”); Ex. 1007 ¶¶ 261–262. Petitioner’s argument with respect to these claims is thus not consistent with the argument it advanced for the independent claims from which these claims depend. Petitioner cannot reasonably rely on one type of prior art LI as the “length indicator” of claim 1, but then shift to a different type of prior art LI when addressing the very same “length indicator” recited in a dependent claim. Moreover, Petitioner fails to explain how or why the special LI “0000000” that is used to indicate the layout of the previous PDU could reasonably be used to also indicate the layout of the current PDU in which the LI appears. For example, if the previous PDU did not meet the condition identified by the “0000000” special value, then the LI would not appear in the next PDU even if that next PDU had a first SDU that ended in that PDU. For these reasons, Petitioner has not provided sufficient explanation or argument to establish obviousness of claims 6 and 21.9” slip op. at 28

      “To support a claim to a genus, a specification must disclose “either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can ‘visualize or recognize’ the members of the genus.” Ariad Pharmaceuticals, Inc. v. Eli Lilly and Co., 598 F.3d 1336, 1350 (Fed. Cir. 2010) (en banc). Here, the recited genus is an interface layer comprising a metal oxide, where the interface layer is configured to provide a specific contact resistivity between a contact metal and a semiconductor of than 1 Ω- μm2. Ex. 1001, 18:37–43. It is undisputed that the only species the pre- 2011 priority applications disclose is TiO2, as set forth in the following passage: Two other properties of the dielectric deserve mention. First is the property of the height of the barrier compared to the semiconductor conduction band (for electrons). In making the barrier thinner than a silicide barrier, the tradeoff may be a higher tunnel barrier (e.g., 2 eV for nitride, compared with about half the gap of 0.6 eV for silicide). Spacer layers may be used with lower barriers (e.g., TiO2 has a barrier of less than 1 eV). Nevertheless, even with the higher barrier to electrons, the present inventors have determined that the resistance can still be one hundred times lower than a contact to silicon with a silicide barrier.

    • Disclosure Requirements (§112) › Enablement (Wands, Amgen full scope)Not enabledNot entitled to earlier dateDecided for petitioner

      “evidence shows, that the disclosure does not enable specific contact resistance down to zero. Ex. 1016, Schubert Decl. ¶¶ 87–90. Instead, Patent Owner argues that one of skill in the art would have understood there to be an “inherent lower limit” and that the claims are enabled because one of skill in the art could achieve that lower limit through experimentation based on the disclosure of patent. We are not persuaded by Patent Owner’s argument, for two main reasons. First, we do not agree that the cases cited by Patent Owner establish that the enablement requirement is satisfied if one of skill in the art could experiment in accordance with the disclosure to find a practical end of an open ended range recited in a claim. Patent Owner principally relies on Andersen Corp. v. Fiber Composites, but the Federal Circuit in that case affirmed the jury verdict of enablement because “the upper limit of the Young’s modulus of the structural member would lie somewhere between the Young’s modulus of the wood fiber and that of the polymer used in the composition.” 474 F.3d at 1377. In other words, there were two known quantities that provided a fixed range. That is not the case here, where Patent Owner does not point to any such predefined limits. Patent Owner also cites a district court case, PerkinElmer Health Scis., Inc. v. Agilent Techs., Inc., 962 F. Supp. 2d 304, 310 (D. Mass. 2013). That case is not directly on point, because it was considering claim construction and not enablement, but that court also found an existing practical upper limit to the” slip op. at 36

    • Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)UnpatentableReference is prior artUnpatentable

      “reference for purposes of anticipation under section 102 [] differs from the enablement standard under section 112.” Rasmusson v. SmithKline Beecham Corp., 413 F.3d 1318, 1325 (Fed. Cir. 2005). Enablement under section 112, which is required for priority under section 120, requires enablement of the full breadth of a claim. Wyeth and Cordis Corp. v. Abbott Laboratories, 720 F.3d 1380, 1384 (Fed. Cir. 2013); MagSil, 687 F.3d at 1384; 35 U.S.C. § 120. Enablement for anticipation does not; rather it requires only enablement of an embodiment or embodiments that fall within the scope of the claim. Chester v. Miller, 906 F.2d 1574, 1577 (Fed. Cir. 1990) (“a CIP's claim for a genus might not be enabled by a parent's disclosure, but that parent may enable a species that anticipates the CIP's claim for a genus . . . . the Court of Custom and Patent Appeals [] made clear the differences between the requirements for claim-anticipating disclosures and for claim-supporting disclosures”) (citing In re Lukach, 442, F.2d 967, 969–970 (CCPA 1971)). Here, the enablement challenge for priority is for a lack of enablement of the full breadth of the recited range, and in particular, a lack of enablement of the lower part of the recited range (that which is at or near zero). No party has argued that the upper part of the recited range (just below 1 Ω-μm2) is not enabled by either the priority applications or Grupp ’483. See, e.g., Pet. 20; PO Resp. 1–2; Pet. Reply 27–28; PO Sur-reply 17– 18. And enablement by a prior art patent is presumed. In re Antor Media Pharm., Inc., 545 F.3d 1312, 1316 (Fed. Cir. 2008); Amgen, Inc. v. Hoechst Marion Roussel, Inc., 314 F.3d 1313, 1355 (Fed. Cir. 2003). Thus, the record does not reflect an inconsistency in holding the priority applications as not enabling the breadth of the recited range while treating Grupp ’483 as enabling the upper part of the range for anticipation. As set forth below, we find that Petitioner has proven that Grupp ’483 anticipates every challenged claim.” slip op. at 42

For example, Petitioner fails to explain how one would have “[a]ppli[ed] the teachings of Shingu to Scranton.” Id. Such a combination is not readily apparent from the references themselves because Shingu relates to moving a camera so that it can take a repeat photograph and does not describe determining the architectural space surrounding the user. Petitioner also does not provide a reason why one of ordinary skill in the art would have combined the cited teachings of Shingu and Scranton to arrive at the claimed features. See id. at 41–42. Nor does Petitioner’s declarant, Dr. Welch, provide testimony explaining how the teachings would have been combined or a reason to make the combination. See Ex. 1002 ¶¶ 79–81. Indeed, as Patent Owner notes, Dr. Welch does not even reference Scranton in his analysis of this claim limitation. See id.; Prelim. Resp. 19–20.

      “and Scranton teaches the “receive a communication” limitation. Petitioner relies on Dr. Welch’s testimony to fill in gaps for what is not expressly disclosed in Shingu. As explained above, Shingu discloses an augmented reality system “that helps users take pictures from the same position and camera angle as a previous photo.” Ex. 1003, 272. Shingu discloses “us[ing] an existing method to estimate camera position as implemented in ARToolKit.” Id. at 271 (emphasis added). Shingu—which describes aiming a camera on an object at a certain angle—does not disclose having a user located within a particular physical space. Petitioner therefore relies on Dr. Welch to assert that it was known ARToolKit could provide the claimed functionality—indicating a relative direction that the virtual reality module (the camera in Shingu) is facing, and a location of a user with respect to the one or more position tracking sensors, wherein the user is located within the particular physical space. Pet. 34–35 (citing Ex. 1002 ¶¶ 69, 72). Dr. Welch’s testimony, in turn, is based on Wagner (Exhibit 1018), which appears to have been downloaded in February 2021. See Ex. 1002 ¶¶ 69 (citing Ex. 1018), 72; Ex. 1018 (footer). Although Dr. Welch gives a date of 2002 for Wagner (see Ex. 1002 ¶ 69), that date does not appear in Exhibit 1018. See Ex. 1018. Petitioner fails to explain in its Petition what evidence supports its assertion that Wagner shows that ARToolKit had been applied to the creation of a floor of a building “more than a decade before the time of the alleged invention” or that the techniques described in Welch were “well known by the time of the alleged invention.” See Pet. 34–35. Nor does the cited testimony from Dr. Welch identify evidence or otherwise provide support for the 2002 date or that the functionality described in Wagner was “well known.” See Ex. 1002 ¶¶ 69, 72. Thus, Petitioner’s assertions and Dr. Welch’s testimony regarding what was known to a person of ordinary skill in the art about the functionality of ARToolKit goes well beyond the express disclosures of Shingu—using “an existing method to estimate camera position” (Ex. 1003, 271)—and, on the current record, are not sufficiently supported by contemporaneous evidence. Petitioner therefore does not sufficiently show that the combination of Shingu and Scranton teaches “receiv[ing] a communication from the one or more position tracking sensors, wherein the communication comprises an indication of a relative direction that the virtual reality module is facing, and a location of the user with respect to the one or more position tracking sensors, wherein the user is located within the particular physical space.”” slip op. at 22
