“Brown’s adapter tube 23 (i.e., the extended portion) does not extend radially from a longitudinal axis of valve assembly 13 (i.e., the toilet fill valve). Ex. 1021, Fig. 1. Mr. Jobin testifies that a POSITA would not be motivated to move adapter tube 23 from a vertical position to a radial position because “a radial extended portion is directly counter to the stated goals of Brown (e.g., reducing noise caused by turbulence), at least insofar system.” Ex. 2013 ¶ 251; see Ex. 1021, 1:9–62. Patent Owner’s argument is persuasive. Petitioner’s analysis and Dr. Cameron’s testimony is conclusory and does not sufficiently explain why a POSITA would be motivated to make the proposed modification to Brown. For example, Petitioner does not sufficiently explain how such a modification would result in a more compact toilet fill valve system that could be adapted to fit in more toilet tank designs. Further, neither Petitioner nor Dr. Cameron sufficiently address Mr. Jobin’s testimony regarding Brown’s desire for a quieter toilet. See Pet. Reply 23; Ex. 1036 ¶ 84.

“description is an objective inquiry into the four corners of the specification from the perspective of a POSA. Using this test, the invention must be described in a manner sufficient to demonstrate that the inventor actually invented the claimed invention. Ariad Pharm., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010). “One shows that one is ‘in possession’ of the invention by describing the invention, with all its claimed limitations, not that which makes it obvious.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 1997). Written description is a question of fact judged as of the relevant filing date. Falko–Gunter Falkner v. Inglis, 448 F.3d 1357, 1363 (Fed. Cir. 2006). An ipsis verbis disclosure, however, is not necessary to satisfy the written description requirement. Vas–Cath Inc. v. Mahurkar, 935 F.2d 1555, 1563 (Fed. Cir. 1991). The disclosure need only reasonably convey to a POSA that the inventor had possession of the subject matter in question, even if every nuance of the claims is not explicitly described in the specification. Id.; see Ariad, 598 F.3d at 1351. Patent Owner argues that the ’993 patent claims were “fully supported as of the filing date of at least the ’606 Application . . . March 11, 2004” because the ’606 Application discloses regulating water flow and a POSITA would know that appropriate devices for regulating water flow includes nonadjustable waterflow restrictors. PO Resp. 68; PO Sur-reply 28–30. Patent Owner’s argument is persuasive. The ’606 Application discloses: [W]hen the toilet fill valve 100 is open and water flows from the water inlet 103 to the water outlets 106 and into a toilet tank, an amount of water is also supplied to the bowl fill valve inlet 113 that flows through the bowl fill valve 109 and out the bowl fill valve outlet 116. By virtue of the manual setting of handle 119 valve 109 is regulated. In this manner, the flow of water is regulated so that enough water flows out of the bowl fill valve 109 to fill a toilet bowl without wasting any water down a drain. Ex. 1012, 47, ¶ 8 (emphasis added); see also Ex. 1001, 2:28–39. As can be seen from the passage above, the ’606 Application discloses regulating an amount of water supplied to a toilet bowl using a valve (i.e., a water flow regulator).

“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.

“2. Whether the Combined Teachings of Burns and LaCelle Describe All Elements of Claims 18, 19, 21, 26, and 29 Valve argues that it is “undisputed that all elements of base claim 1 are taught by the combination of Burns in view of LaCelle.” Valve Remand Br. 21 (citing Pet. 33–38; Ex. 1009 ¶¶ 23–25, 27–29). Ironburg disagrees, responding that “neither Burns nor LaCelle discloses the first control with an elongate member having a second surface arranged to be non-parallel with the back, outer surface of case.” Ironburg Remand Br. 20. Ironburg’s argument appears to rest on the issue of whether LaCelle describes its underside items as a control. We have already found that LaCelle’s underside items are controls as explained above. However, even if LaCelle did not disclose that its underside items were controls, Valve relies upon Burns as describing this aspect of claim 1. Valve Supp. Reply 9–10. Either way, Valve persuades us that the Burns and LaCelle, when combined as Valve suggests, teach every element of claim 1. In Parts II.D.1–4 above, we have also analyzed the parties’ arguments and supporting evidence on the issues of whether Burns describes the limitations introduced in each of claims 18, 19, 21, 26, and 29. For the reasons expressed above, Valve persuades us that Burns and LaCelle, when combined as Valve suggests, teach every element of dependent claims 18, 19, 21, 26, and 29. We have already concluded that Valve has proven that an ordinarily skilled artisan would have been motivated to combine teachings of Burns and LaCelle to arrive at the invention of claim 1, and those motivations also suffice for dependent claims 18, 19, 21, 26, and 29, all of which introduce limitations that we find to be described by Burns.

“On the first issue, we find that LaCelle’s underside items would have been understood by an ordinarily skilled artisan as a “control.” LaCelle describes the article illustrated in all its figures as a “game controller.” Ex. 1005, code (57). Dr. Rempel testifies that even if an ordinarily skilled artisan “were not 100% certain that the identified features on the back of the . . . LaCelle . . . controller[] are functional controls, their location and appearance certainly suggests functional back controls to one of ordinary skill in the art (even if another interpretation were also possible).” Ex. 1019 ¶ 12. The Federal Circuit has instructed us that we erred by failing to consider Dr. Rempel’s testimony supporting Valve’s Supplement Reply. Valve II, at 16. Dr. Rempel’s testimony is consistent with the manner in which LaCelle graphically depicts the items on the underside of its game controller, and we credit that testimony as being persuasive. Additionally, as we explain below, we do not find that Valve must prove that LaCelle describes its underside items as a control to support its position that an ordinarily skilled artisan would have been motivated to apply the curved shape of LaCelle’s underside items to the surface of Burns’s elongate members. On the second issue, we find that LaCelle undisputedly describes its items on the underside of the controller as being curved. On the third issue, the probative value of Valve’s Supplemental Reply argument and supporting evidence, the Federal Circuit held that we ignored important testimony establishing that an ordinarily skilled artisan “‘would have combined LaCelle and Burns’ and ‘would recognize that the predictable result of the combination — a back paddle having an end that is curved like that of LaCelle — could have better coupling with the user’s finger.’” Id., at 17–18 (quoting Ex. 1019 ¶ 39 with added emphasis). The Federal Circuit also refocused our obviousness inquiry on “whether a person of ordinary skill in the art would have been motivated to combine Burns and LaCelle, not whether the combination would with absolute certainty result in the desired outcome.” Id. at 18. Dr. Rempel’s testimony cited by the Federal Circuit establishes that an ordinarily skilled artisan would have been motivated to apply the curved shape of LaCelle’s underside items to Burns’s elongate members. Our original Remand Decision failed to consider that testimony, and the Federal Circuit has identified that failure as error. Valve II, at 17.

Dr. Hesselink credibly testifies that while Fuhse262 depicts rays that form a light spot, the rays depicted are “chief rays” that depict only the center rays of light for each optical element. Ex. 1003 ¶¶ 169–170. Ambient light, however, reflects from the entire surface of the mirrors and forms reflected beams of light, not just the center rays aimed at the center point. Id. ¶ 170. According to Dr. Hesselink, the “chief ray” is representative of the larger bundle of rays that form the beams of light reflected off of the mirrors. See Id. ¶ 44. The volume of the voxel is set by the intersection of these beams and the center of the voxel is the point at which the center rays of each beam intersect. Id. ¶ 171. Although Dr. Lindstrand testifies a POSITA would not have understood Fuhse262 to disclose creating a voxel (Ex. 2004 ¶ 43), Dr. Lindstrand does not dispute Dr. Hesselink’s testimony that light would reflect off of the entire surface of Fuhse262’s mirrors and form reflected beams of light. See Ex. 2004 ¶¶ 42– 58; Ex. 1055, 112:15–21 (“You also agree the ambient light would not just strike the center of the surface, it would strike the entire surface, correct? . . . THE WITNESS: I would say that that is a fair and accurate description.”) would reflect off the entire surface of Fuhse262’s micromirrors and would create a voxel when they intersect with each other, provides sufficient support demonstrating how a person of ordinary skill in the art would have understood Fuhse262’s disclosure of light rays being reflected off of mirrors and converging at a light spot shown in Figure 10. See Unification Techs. LLC v. Micron Tech. Inc., 2024 WL 3738401 at *7 (Fed. Cir.

“As to Petitioner’s more general allegations regarding motivation to combine the embodiments of Fuhse262 and reasonable expectation of success, we agree with Petitioner for the reasons provided in the Petition and summarized above. Specifically, we agree with Petitioner that Fuhse262 concave mirrors and lenses with embodiments that use micromirrors. See Ex. 1006 ¶ 83 (“In order to still obtain a higher resolution in the produced light-spot image with an unchanged high floating height, the large mirrors or lenses used in the previous exemplary embodiments are each replaced by a plurality of smaller micromirrors or microprisms, which together have essentially the same optical effect as the original optical element.”). We also agree that the embodiments of Fuhse262 build on each other and often refer back to each other. For example, Fuhse262 expressly refers back to “previous exemplary embodiments” when explaining that micromirrors may replace other optical elements in the various embodiments. Ex. 1006 ¶ 83. Fuhse262’s Figures 8(a) through 8(d) build on each successive example, adding and modifying the configuration of mirrors disclosed in the previous figure. See Id. ¶¶ 88, 94 (explaining that Figure 8(b) is based on Figure 8(a) but shows mirrors arranged in checkerboard-like manner and Figures 8(c) and 8(d) further modify the configuration with every “fourth field” and “ninth field” respectively being assigned to specific light spots.) Fuhse262 also explains that Figure 9 is a sectional view of Figure 8 and that Figure 10 illustrates the “calculation of the flat mirror surfaces of the micromirrors” of Figures 8 and 9. Id. ¶¶ 91, 95. For the aforementioned reasons, we determine that Petitioner has demonstrated, by a preponderance of the evidence, that a person of ordinary skill would have been motivated to combine the teachings of the relied upon embodiments of Fuhse262.” slip op. at 18

“Mr. Bauer further testifies: For electric-powered breast pumps, the only two options for providing electricity to the pump was either via a wire plugged into an outlet or via a battery, as would have been well-known to a POSITA. It would have been obvious for a POSITA to utilize a battery as the power source for Furrer’s pump as it was one of the two available options and would have provided known benefits. Ex. 1003 ¶ 93. As to why this a person of ordinary skill would have chosen the option of a battery powered breast pump, Mr. Bauer testifies that: Selection of battery power for Furrer’s pump would have beneficially provided a portable system that was usable during travel. Additionally, such a configuration would have allowed the user to move freely about a room, or be positioned in a location within a room without being tethered to a wall plug, allowing the user to, for example, sit or lay in the most convenient location while using the system without having to worry about being close to an outlet. Such mobility provided by selecting battery power for Furrer’s pump would have particularly aligned with Furrer’s suggestion for a ‘hands-free’ and discrete solution. Id.

“A reference may be said to teach away when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). Patent Owner’s argument is unpersuasive at least because Dinka expressly describes using VoIP technology on computer terminals 102. Ex. 1006, 5:45–48 (“A plurality of computer terminals 102 are shown coupled to the Internet 101, each comprising a network interface for communicating over the Internet.”), 6:7–8 (“Each computer terminal 102 is installed with a communication client application 110.”), 6:23–26 (“The communication client applications 110 [of computer terminals 102] and 113 [of television sets 103] are preferably peer-to-peer clients for setting-up and conducting VoIP calls according to peer-to-peer principles as discussed above.”). Thus, Dinka does not lead a skilled artisan in a direction divergent from the path taken in the ’347 patent. Moreover, “[a] reference may be read for all that it teaches, including uses beyond its primary purpose.” In re Mouttet, 686 F.3d 1322 1331 (Fed. Cir. 2012). Thus, even though Dinka expresses a preference for conducting VoIP calls using a television set, a skilled artisan still would have considered Dinka’s teaching of using computers for such calls. See id. at 1334 (“This court has further explained that just because better alternatives exist in the prior art does not mean that an inferior combination is inapt for obviousness purposes.”).

“Patent Owner’s argument are persuasive. We agree with Patent Owner that a plain reading of the wherein clause requires the treating to begin at the introitus and extend at least the first centimeter into the vagina and up to 3.5 cm in from the introitus. This construction is consistent with the ’511 patent’s Specification, which states: In typical embodiments, the length of the energy delivery element is about 1 to about 3 cm in length, in other embodiments it may be as long as about 4 cm. This is a length well adapted to treating the lower aspects of the vagina, wherein treatment by the method comprises contacting the vaginal epithelium in a region that extends from the introitus inward to a position about 3 to 4 cm inward from the introitus. In some embodiments of the invention, the method can b[e] practiced with a single row of parallel contract sites immediately inside the introitus. In other embodiments, the method may include deeper rows, or rows that overlap an initial row, while keeping the contact sites within the lower portion of the vagina.

Given the plain language of claim 1, consistent with the ’511 patent’s Specification, we construe “heating a portion of the vagina extending from the introitus inwardly to a location from 1 cm to 3.5 cm in from the introitus” to require heating a portion of the vagina beginning at the introitus and extending at least the first centimeter into the vagina and up to 3.5 cm in from the introitus.” slip op. at 12
