“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). See Hollmer v. 14 The parties do not dispute that the ’993 patent and the earlier parent applications, including the ’904 Application and the ’606 Application, have the same pertinent portions of their specifications. See PO Resp. 71, n.16; Ex. 1004 ¶ 324. 15 Schuster issued on January 31, 2012, from Application No. 12/786,904, filed on May 25, 2010. Ex. 1029, code (21), (22), (45).

Claim 20 depends from claim 14 and recites the same additional limitation. Id. at 12:21–24. Claims 19 and 20, thus, require the water flow regulator to be an adjustable water flow regulator.

“parties, we do not find the merits to be particularly strong on the current record. For example, limitation [1-4] recites, in part, “a locking nut having . . . an external thread on an outside surface of the locking nut.” Ex. 1001, 9:46–47. In alleging obviousness based in part on Orphanos, Petitioner equates the claimed “locking nut” to Orphanos’s collet 230 in a first embodiment of Orphanos, or Orphanos’s collet portion 1052 in a second embodiment of Orphanos. Pet. 37–38. Petitioner acknowledges that the collet and collet portion do not have external threads, but rather are designed to have a snap-fit engagement with the inner sidewall of the baseplate’s central throughbore. Id. at 38. Petitioner argues that modifying the collet and collet portion to have external threads would have been obvious to the skilled artisan in view of Orphanos’s teachings and the knowledge of a person having ordinary skill in the art. Pet. 38–42 (arguing, inter alia, that it would have been “a substitution of a known part for a known problem” and “obvious as a matter of design choice”). Petitioner does not allege that replacing the snap-fit coupling with external threads would either: (1) result in any advantages; or (2) preserve any of Orphanos’s stated benefits of its snap-fit arrangement. See Pet. 34–37. That Petitioner describes no advantages to making its proposed modification potentially undermines Petitioner’s case that the skilled artisan would have done so. Cf. Winner Int’l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 n.8 (Fed.

“Petitioner’s arguments regarding the central post and locking nut include an implicit claim construction argument that these components need not be separate structures. Pet. 74, 76–81. Patent Owner, on the other hand, would have us interpret the claim to require that they be separate structures. Patent Owner raises credible evidence to support its theory. Specifically, Patent Owner directs us to the language of claim 1, which separately recites “a central screw” and “a locking nut.” Prelim. Resp. 51; see Ex. 1001, 9:44–53. Patent Owner further contends, in view of the claim language, that the claimed central post and locking nut are separate and distinct components. According to Patent Owner, however, Lefebvre’s main head and anchor rod portions are parts of a single monolithic anchoring screw. Prelim. Resp. 53–58. Where a claim lists elements separately, there is a rebuttable presumption that these elements have separate and distinct physical structures. See Google LLC v. EcoFactor, Inc., 92 F.4th 1049, 1058 (Fed. Cir. 2024) (citing Powell v. Home Depot U.S.A., Inc., 663 F.3d 1221, 1231–1232 (Fed. Cir. 2011)). The presumption may be rebutted by the intrinsic record. Id. At this stage, however, Petitioner does not address that claim 1 appears to separately recite a central post and a locking nut, and does not direct us to any portion of the intrinsic record that might rebut the presumption that these elements are, therefore, separate and distinct structures. See Pet. 73–77. Petitioner also argues that the claim terms “baseplate central channel” and “central channel . . . configured to interface with the baseplate” are indefinite. Pet. 95–102.

Dr. Cameron testifies: “Integrally molding the extended portion of Guoxin with the inlet device as taught by Ho would be advantageous in improving the strength and integrity of the connection, and to make it easier to manufacture and assemble.” Ex. 1004 ¶ 125.

“embodiments that operate with a low frequency driving signal in a double-ended configuration, Patent Owner did not recite “low frequency” or “double-ended” in its claims and instead chose the broader term “first driving mode.” See In re Am. Acad. of Sci. Tech Ctr., 367 F.3d 1359, 1369 (Fed. Cir. 2004) (“We have cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.”). The fact that a limitation in the specification may define over the prior art does not justify importing that limitation into the claims unless a term is expressly defined such that the patentee becomes his own lexicographer or there is an express disavowal of claim scope. See GE Lighting Sols., LLC v. AgiLight, Inc., 750 F.3d 1304, 1308–09 (Fed. Cir. 2014). There is no evidence of an express disavowal here. As to lexicography, we disagree with Patent Owner’s contention that the Specification defines the phrase “first driving mode.” Patent Owner relies on the mere fact that the specification describes an embodiment with a first driving mode that has a low frequency driving signal and is in a “double-ended” configuration, but this is not sufficient to define the term. The specification does not require that a low frequency driving signal must necessarily be used. In fact the specification, although not entirely clear, suggests that the driving signal may be from a high frequency ballast. Ex. 1001, 51:8–14. Thus, the fact that the patent here discloses a low frequency driving signal does not mean that all the claims are directed to such a driving signal. See E-Pass Tech., Inc. v. 3Com Corp., 343 F.3d 1364, 1368–69 (Fed. Cir. 2003). Indeed, dependent claim 15 recites “the first driving mode is performed when the external driving signal is a relatively low frequency or voltage signal,” while the independent claims were directed to a more general driving signal. The doctrine of claim differentiation suggests that the independent claims here should not include explicit limitations of a dependent claim. See Phillips, 415 F.3d at 1315 (“[T]he presence of a dependent claim that adds a particular limitation gives rise to a presumption that the limitation in question is not present in the independent claim.”); Liebel-Flarsheim Co. v.

“content for output.” Id. at 89. We determine, however, that Petitioner’s argument under Step 2A Prong One that claim 1 is directed to the “obtaining content for output” is not substantially different from the Examiner’s determination that claims 1‒20 recite “collecting information, analyzing it, and displaying certain results of the collection and analysis.” Compare Pet. 37–88 (citing e.g. Electric Power), with Ex. 2001, 193–194 (also citing Electric Power). In both cases, the argument is the same or substantially the same, i.e., that similarly identified subject matter of the claim is obtaining (collecting) data and displaying (outputting) it. Nevertheless, as to Step 2A Prong Two, we determine that the claims at issue in the ’096 prosecution differ in material ways from the ’903 patent claims at issue in this PGR. Specifically, the ’096 patent claims recite a touchscreen interface not recited in the ’903 patent claims. Additionally, the ’903 claims focus on the “output device” as performing the patented steps but in the ’096 prosecution history the “‘information apparatus performs the patented steps and “is integral to the claims” (as the Applicant argued). See Ex. 2008 [comparison of ’096 prosecution claims and ’903 claims]; Ex. 2001, 150; see also Pet. 89 (“the claims at issue in the ’067 application were different than the claims of the ’903 patent addressed here.”). rejection and arguments in the ’096 prosecution history turns on whether the claims in this PGR recite different elements that must be determined to integrate the judicial exception into a practical application (i.e., Prong Two of Step 2A). Petitioner argues that an essential element different than the ’096 claims, i.e. the output device, does not integrate the judicial exception into a practical application because the claims do not amount to an improvement to computer functionality. Pet. 37–72. We find this a close case. Nevertheless, due to the differences in the claims, we determine that the Examiner’s withdrawal of the § 101 rejection in light of the applicant’s arguments regarding the claim being directed to a specific technical solution is not substantially the same argument that Petitioner’s presents in the Petition as to Prong Two of Step 2A.” slip op. at 22

It extends only to that which is 1997).
