“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.

“§ 325(d), the Board uses the following two-part framework: (1) determining whether the same or substantially the same art previously was presented to the Office or whether the same or substantially the same arguments previously were presented to the Office; and (2) if either condition of the first part of the framework is satisfied, determining whether the petitioner has demonstrated that the Office erred in a manner material to the patentability of challenged claims.

In applying the two-part framework, we consider several non-exclusive factors, including: (a) the similarities and material differences between the asserted art and the prior art involved during examination; (b) the cumulative nature of the asserted art and the prior art evaluated during examination; (c) the extent to which the asserted art was evaluated during examination, including whether the prior art was the basis for rejection; (d) the extent of the overlap between the arguments made during examination and the manner in which petitioner relies on the prior art or patent owner distinguishes the prior art; (e) whether petitioner has pointed out sufficiently how the examiner erred in its evaluation of the asserted prior art; and (f) the extent to which additional evidence and facts presented in the petition warrant reconsideration of the prior art or arguments.

“Patent Owner has shown sufficient written description support for the claims, including the disputed “detecting” limitation. The “decode-to-learn- ‘D’” description in the specification of the ’146 patent and in the provisional application to which the ’146 patent claims priority describe a specific procedure for the claimed “detecting, from the received wireless packet, the second header field which repeats the first header field.”3 See Ex. 1001, 2 Petitioner specifically asserts that Huang qualifies under 35 U.S.C. §102(b). Pet. 2, 19 (“by more than a year”). However, Huang’s patent issuance date of April 28, 2020 does not qualify under § 102(b) because it is less than one year before the December 29, 2020 filing date of the ’146 patent. Nevertheless, Petitioner has made an effective showing that Sun would qualify as prior art sufficient to shift the burden of production to Patent Owner. 3 Patent Owner does not explicitly show support for each of the applications in the priority chain. Patent Owner also cites to a Pre-Grant Publication rather than the underlying application despite the fact that such a Publication may include amendments to the originally filed application that would not evidence written description.

“ordinary skill in the art at the time of the invention of the ’948 patent would have had “(i) a Bachelor’s degree in Physics, Optical Sciences, or equivalent education or training, as well as (ii) approximately three years of experience in designing multi-lens optical systems.” Id. at 12 (quoting Pet. 13–14 (citing Ex. 1003 ¶ 28)). We also found that “[l]ack of work experience could have been offset by additional education, and vice versa,” and that one of ordinary skill in the art “would have understood the fundamentals of optical aberration theory, and understood and used standard techniques for making lenses cheaper and more effective, especially for lens systems used in mobile devices.” Id. (quoting Pet. 14; Ex. 1003 ¶¶ 28, 30). We also agreed with Petitioner and found that one of ordinary skill in the art “would have known how to use lens design software such as Code V, Oslo, and ZEMAX, and would have taken a lens design course or had equivalent training.” Id. (quoting Pet. 14; Ex. 1003 ¶ 29). We also agreed with Petitioner and found that one of ordinary skill in the art “would have regularly used such software to create new lens designs, often using pre-existing lens designs as a starting point and then performing routine optimizations to reach a desired design.” Id. at 12–13 (quoting Pet. 14; Ex. 1003 ¶ 29). Patent Owner does not identify a level of skill in the art that one would have had at the time of the invention of the ’948 patent or identify any shortcoming in Petitioner’s formulation. See PO Resp. 16–17. Because Petitioner’s definition of the level of skill in the art is consistent with the ’948 patent and the asserted prior art, we maintain it for purposes of this Final Written Decision.

“Patent Owner argues that construing the challenged “claims to include first and second lens elements having the same refractive power . . . is improper.” PO Resp. 21. According to Patent Owner, one of ordinary skill in the art “would construe the [’]948 [p]atent claims to include first and second lens elements in the form of a ‘doublet,’ which requires the respective lens elements to have opposite refractive power, and thus includes only configurations” of “positive-negative” and “negative-positive” for the first and second lens elements, respectively. Id. at 20–21. In other words, “[t]he proper construction of the ’948 [p]atent claims is that the first and second lens elements may have positive-negative or negative-po[sitive] refractive powers, but would not include first and second lens elements having the same refractive polarity,” according to Patent Owner. Id. at 26. Thus, the parties agree that the challenged claims should be construed to encompass at least a lens system having a first lens element with a negative refractive power and a second lens element with a positive refractive power. See, e.g., Pet. 33; PO Resp. 21. We conclude that such a lens system is consistent with the plain language of the challenged claims. See, e.g., Ex. 1001, 12:8–26, 13:14–38, 14:16–46 (reciting first and second lens elements without reciting a specific refractive power polarity for the independent claims). And we determine that no claim terms require further construction in light of our findings below. See, e.g., Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed.

“In sum, we determine that the 2012 application does not provide written description support for an imaging lens system with a negative refractive power first lens and a positive refractive power second lens. And the agreed scope of the challenged claims includes such a configuration, and thus, the written description of the 2012 application does not support the full breadth of the challenged claims. We therefore determine that the challenged claims of the ʼ948 patent do not benefit from the priority date of the 2012 application. Therefore, we determine that Chen-069 is prior art to the challenged claims of the ʼ948 patent.” slip op. at 23
