“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.

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

“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.

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.

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.

Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed.

“1. Analysis of Claims 1–18 Schuster is available as prior art if the ’993 patent is only entitled to its January 27, 2014, filing date and not entitled to claim priority to earlier filing dates of the parent applications. On its face, the ’993 patent claims priority to a number of earlier parent applications, including Application No. 12/786,904 (the ’904 Application) filed May 25, 2010, and the Application code 63. Petitioner contends that the ’993 patent is not entitled to claim priority to the filing date of the earlier parent applications, and, thus, Schuster, a parent application of the ’993 patent, is available as prior art.15 Pet. 91–92. Petitioner alleges that the earlier parent applications, specifically Application No. 12/786,904 (the ’904 Application), do not provide written description support for the ’993 patent’s claim term “water flow regulator.” According to Petitioner, “water flow regulator” encompasses both adjustable devices for restricting the flow of water (i.e., valves) and fixed devices for restricting the flow of water (i.e., restrictors). Pet. 15. Petitioner contends that the ’904 Application does not provide support for water flow restrictors and, thus, does not provide support for the broader claim term water flow regulators. Id. at 14–15, 91–92. Petitioner argues that only adjustable water flow devices (i.e., valves) are supported by the ’904 Application. Id. Petitioner, thus, asserts that earliest effective filing date of the ’993 patent’s claims is the filing date of its application, January 27, 2014. Id. at 92. To be entitled to claim the benefit of an earlier filing date under 35 U.S.C. § 120 each application in the priority chain must comply with the written description requirement of 35 U.S.C. § 112(a).

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.

MTA Opp. 12 (emphases added).

“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. Graham, 383 U.S. at 17–18.6 Petitioner asserts that claims 1–2, 7–8, 10, 12–13, and 17–18 are unpatentable under § 103 as obvious in view of Paxton and Sutton. See Pet. 6, 18–64.

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