    “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).

Patent Owner’s construction is consistent with the plain language of the claims, which requires the extended portion be “integrally molded with” the body and not just the extended portion be integral with the body. Further, we determine that Patent Owner’s construction is consistent with the ’105 patent, which discloses that “the bowl fill valve 109 may be molded as a portion of the toilet fill valve 100 or it may be snapped or clamped into place, or it may be attached to the toilet fill valve 100 in some other manner, etc.” Id. at 2:23–26 (emphasis added).

Rather, we agree with Petitioner, that Guthery’s description of a request-to-send packet as shown in Figure 8, which does not include information about the size of the message, indicates that the size information is not required by the request-to-send packet in at least some embodiments of Guthery. Ex. 1005, 8:65–9:12, Fig. 8; see id. at 8:25–29 (The “present invention is not limited to the packet types discussed and in fact assumes that new types can and will be defined in the future as needed.”); 7:43–50 (“In one particular embodiment,” packets have a fixed number of bytes, but “in other embodiments, packet types may have different sizes.”). We agree with Petitioner, that Guthery discloses multiple embodiments, and the combination made by Petitioner relies on the embodiments shown in Figures 14 and 15, where the requested application only needs two buffers and therefore would know, without receiving information from the request-to-send packet, to ask for two buffers. Ex. 1005, 12:19–59. We find that a person of ordinary skill, in combining the teachings in Guthery with Nozawa to identify and initialize an application most likely to be selected by the smart card reader, would rely on (a) information about the size of a message as shown in Figure 8, (b) Guthery’s teaching of an application programmed to determine its own memory requirements (Ex. 1005, 9:25–31), and (c) Guthery’s teaching of an application that only needs two buffers as shown in Figures 15A-15D, to preemptively transmit a permission-to-send packet from the application to the reader without waiting to receive the request-to-send packet from the reader, to yield the benefit of improving efficiency and reducing latency as taught by Nozawa.

    “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.

    “mental steps that an ordinarily skilled artisan theoretically might have taken after reviewing the minimal disclosure in the ’423 patent. The ’423 patent does not discuss any properties of metal oxides (other than the lower barrier of the metal oxide TiO2) or design considerations concerning the selection of particular oxides to use in the claimed structure, particularly in the context of MIGS separation. Dr. Kuhn cites very little, if any, evidence to support her testimony regarding the knowledge of an ordinarily skilled artisan. Thus, we do not credit this analysis as showing that an ordinarily skilled artisan would have found that the inventors of the pre-2011 priority applications possessed the recited genus. See Ariad, 593 F.3d at 1352 (a description that merely renders the invention obvious does not satisfy the written description requirement); PowerOasis Inc. v. T-Mobile USA, 522 F.3d 1299, 1306 (Fed.

    “To support a claim to a genus, a specification must disclose “either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can ‘visualize or recognize’ the members of the genus.” Ariad Pharmaceuticals, Inc. v. Eli Lilly and Co., 598 F.3d 1336, 1350 (Fed. Cir. 2010) (en banc). Here, the recited genus is an interface layer comprising a metal oxide, where the interface layer is configured to provide a specific contact resistivity between a contact metal and a semiconductor of than 1 Ω- μm2. Ex. 1001, 18:37–43. It is undisputed that the only species the pre- 2011 priority applications disclose is TiO2, as set forth in the following passage: Two other properties of the dielectric deserve mention. First is the property of the height of the barrier compared to the semiconductor conduction band (for electrons). In making the barrier thinner than a silicide barrier, the tradeoff may be a higher tunnel barrier (e.g., 2 eV for nitride, compared with about half the gap of 0.6 eV for silicide). Spacer layers may be used with lower barriers (e.g., TiO2 has a barrier of less than 1 eV). Nevertheless, even with the higher barrier to electrons, the present inventors have determined that the resistance can still be one hundred times lower than a contact to silicon with a silicide barrier.

  • Disclosure Requirements (§112) › Enablement (Wands, Amgen full scope)Not enabledNot entitled to earlier dateDecided for petitioner

    “evidence shows, that the disclosure does not enable specific contact resistance down to zero. Ex. 1016, Schubert Decl. ¶¶ 87–90. Instead, Patent Owner argues that one of skill in the art would have understood there to be an “inherent lower limit” and that the claims are enabled because one of skill in the art could achieve that lower limit through experimentation based on the disclosure of patent. We are not persuaded by Patent Owner’s argument, for two main reasons. First, we do not agree that the cases cited by Patent Owner establish that the enablement requirement is satisfied if one of skill in the art could experiment in accordance with the disclosure to find a practical end of an open ended range recited in a claim. Patent Owner principally relies on Andersen Corp. v. Fiber Composites, but the Federal Circuit in that case affirmed the jury verdict of enablement because “the upper limit of the Young’s modulus of the structural member would lie somewhere between the Young’s modulus of the wood fiber and that of the polymer used in the composition.” 474 F.3d at 1377. In other words, there were two known quantities that provided a fixed range. That is not the case here, where Patent Owner does not point to any such predefined limits. Patent Owner also cites a district court case, PerkinElmer Health Scis., Inc. v. Agilent Techs., Inc., 962 F. Supp. 2d 304, 310 (D. Mass. 2013). That case is not directly on point, because it was considering claim construction and not enablement, but that court also found an existing practical upper limit to the” slip op. at 36

Enablement under section 112, which is required for priority under section 120, requires enablement of the full breadth of a claim. Wyeth and Cordis Corp. v. Abbott Laboratories, 720 F.3d 1380, 1384 (Fed. Cir. 2013); MagSil, 687 F.3d at 1384; 35 U.S.C. § 120. Enablement for anticipation does not; rather it requires only enablement of an embodiment or embodiments that fall within the scope of the claim. Chester v. Miller, 906 F.2d 1574, 1577 (Fed. Cir. 1990) (“a CIP's claim for a genus might not be enabled by a parent's disclosure, but that parent may enable a species that anticipates the CIP's claim for a genus . . . . the Court of Custom and Patent Appeals [] made clear the differences between the requirements for claim-anticipating disclosures and for claim-supporting disclosures”) (citing In re Lukach, 442, F.2d 967, 969–970 (CCPA 1971)). Here, the enablement challenge for priority is for a lack of enablement of the full breadth of the recited range, and in particular, a lack of enablement of the lower part of the recited range (that which is at or near zero). No party has argued that the upper part of the recited range (just below 1 Ω-μm2) is not enabled by either the priority applications or Grupp ’483. See, e.g., Pet. 20; PO Resp. 1–2; Pet. Reply 27–28; PO Sur-reply 17– 18. And enablement by a prior art patent is presumed. In re Antor Media Pharm., Inc., 545 F.3d 1312, 1316 (Fed. Cir. 2008); Amgen, Inc. v. Hoechst Marion Roussel, Inc., 314 F.3d 1313, 1355 (Fed. Cir. 2003). Thus, the record does not reflect an inconsistency in holding the priority applications as not enabling the breadth of the recited range while treating Grupp ’483 as enabling the upper part of the range for anticipation. As set forth below, we find that Petitioner has proven that Grupp ’483 anticipates every challenged claim.” slip op. at 42
