      “Patent Owner proposes that: A [person of ordinary skill in the art (“POSITA”)] in the field to which the ’105 Patent is directed would have had at least a Bachelor of Science degree in mechanical engineering or a related field or, as a substitute, at least two years of work or” slip op. at 9

      “Patent Owner responds that: a POSITA would not have been motivated to make the proposed modification, nor does the Petition include any analysis regarding why a POSITA would be motivated to move from a vertical extended portion to a radial extended portion. Indeed, a radial extended portion is directly counter to the stated goals of Brown (e.g., reducing noise caused by turbulence), at least insofar as it introduces another sudden directional change into the fluid flow system.

      “Patent Owner argues that the ’105 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. 63–65; PO Sur-reply 26–29. 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 of the bowl fill valve 109, the flow of water through the bowl fill 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. 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). Ex. 2013 ¶ 288. Further, the ’606 Application states: The bowl fill valve 109 may be, for example, a ball valve, a gate valve, a globe valve, a plug valve, a diaphragm valve, a butterfly valve, a needle valve, a sliding gate, a quick turn valve, a knife valve or any other appropriate type of valve as can be appreciated by those with ordinary skill in the art.” slip op. at 42

      “description is an objective inquiry into the four corners of the specification from the perspective of a POSA.

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

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 . . .

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.

      “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.

      “In the Decision on Institution, we adopted Petitioner’s proposed level of ordinary skill in the art, stating it was “consistent with the evidence of record, including the asserted prior art.” Dec. Inst. 7. Petitioner does not challenge Patent Owner’s modification to its proposed definition, and Petitioner’s expert, Dr. Drasler, agrees that experience in the field of prosthetic cardiovascular implants would have included experience with transcatheter prosthetic cardiovascular implants as well as delivery systems and methods used to implant such prostheses. See generally Pet. Reply; Ex. 2048, 11:6–12:1. Thus, based on our review of the complete record, we adopt Petitioner’s definition of the level of ordinary skill in the art, modified as proposed by Patent Owner.

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

      “We agree with Petitioner. Patent Owner’s proposal that the distal end of the delivery catheter “houses the prosthetic” is in tension with the express language of the claim because the proposed construction suggests that “houses” necessarily means more than “at least” part of the prosthesis is disposed in the distal end. Indeed, if “houses” was not more limiting than “at least partially disposed” there would be no need to further define the spatial relationship between the distal end of the catheter and the prosthetic valve. Petitioner further argues that the Patent Owner’s construction is improper because it “wrongly limits the term to require that ‘the proximal end includes a handle that controls the deployment of the implant.’” Pet. Reply at 3 (citing PO Resp. 37–38). Petitioner asserts that the claims do not recite a handle and the ’897 patent’s “specification makes clear that a handle is a separate, optional component that is not integral to a delivery catheter: inner tubular member ‘can’ be connected to handle 907 and outer tubular member ‘can be connected’/‘attach[ed]’ to outer sheath handle 908.” Id. (citing Ex. 1001, 20:19–29, 26:30–33, claim 10). We again agree with Petitioner. Although the specification describes an embodiment in which proximal end 905 of inner tubular member 904 can be connected to handle 907 and proximal end 902 of outer tubular member 901 can be connected to handle 908 (Ex. 1001, 20:19–26), it is generally improper to read limitations from specific embodiments into the claims. See Cadence Pharms. Inc. v. Exela PharmSci Inc., 780 F.3d 1364, 1369 (Fed. Cir. 2015) (“[E]ven if all of the embodiments discussed in the patent included a specific limitation, it would not be proper to import from the patent’s written description limitations that are not found in the claims themselves.” (internal quotations omitted)); SuperGuide Corp. v. DirecTV Enters., Inc., 358 F.3d 870, 875 (Fed. Cir. 2004) (“Though understanding the claim language may be aided by the explanations contained in the written description, it is important not to import into a claim limitations that are not a part of the claim.”). Furthermore, at the oral hearing, Patent Owner indicated that “the proximal end includes a handle that controls the deployment of the implant” part of its proposed construction is not necessary.
