    “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.

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).

The standard for instituting an inter partes review is set forth in 35 U.S.C. § 314(a), which provides that an inter partes review may not be instituted unless “there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” The Supreme Court has held that the Board, in a decision to institute under 35 U.S.C. § 314(b), may not institute review on less than all claims challenged in the petition.

    “Based on this record, it appears that the main distinction between Petitioner’s ordinary skilled artisan and Patent Owner’s is that Patent Owner further requires familiarity with wireless networks. We note, however, that the monitoring systems of the asserted prior art include wireless networks. In view of this, because Petitioner’s requirement of experience designing railcar, train, vehicle, or any other similar monitoring systems includes some familiarity with wireless networks, we adopt Petitioner’s articulation of the level of ordinary skill in the art, which is consistent with the ’223 patent and the asserted prior art, and we apply it in our obviousness evaluations below. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art, itself, can reflect appropriate level of ordinary skill in art).

    “The full record makes clear that the parties do not dispute the portion of Petitioner’s proposed level of ordinary skill regarding education and years of experience. Compare Pet. 14–15, with PO Resp. 3. Patent Owner acknowledges that the analysis does not depend on whether Petitioner’s proposed level of ordinary skill or Patent Owner’s proposal is adopted. See PO Resp. 3–4; Ex. 2003 ¶ 34 (testifying that Patent Owner’s declarant has an understanding of the capabilities of one of ordinary skill in the art irrespective of which proposed skill level is adopted), ¶ 35. The parties’ proposals are consistent with the factors of GPAC, the disclosure of the ’728 patent, and the prior art of record. Ex. 1012 ¶ 71 (testifying that Petitioner’s proposed level of ordinary skill is based on considering the factors of GPAC); Ex. 2003 ¶ 32 (testifying that Patent Owner’s proposed level of ordinary skill is based on the ’728 patent); GPAC, 57 F.3d at 1579. In view of the above, we see no reason to disturb our preliminary determination regarding the level of ordinary skill in the art. Thus, we maintain and reaffirm that one of ordinary skill in the art would have had “(1) a bachelor’s degree in mechanical engineering or a similar field that includes thermal sciences; and (2) at least two years of industrial experience on the design and evaluation of thermal management of electronic systems and heat pipes/TGPs.” Pet. 14–15; Ex. 1012 ¶ 71; Ex. 2003 ¶ 35.

No claim term was interpreted expressly for our Institution Decision. Inst. Dec. 10. Patent Owner does not propose expressly any interpretation for any claim term. See generally PO Resp. Patent Owner, however, states that “claim 1 of the ’728 Patent expressly defines the claimed ‘pitch’ of the microfabricated structures as being ‘a distance from a center of one microfabricated structure to a center of a next neighboring microstructure.’” Id. at 12 (citing Ex. 1001, 14:45–48).

    “Petitioner appears to be seeking verbatim support, when, as argued by Patent Owner, the Specification does not need to provide exact or verbatim support to meet the written description requirement. See Pet. 20; PO Resp. 32. One of ordinary skill in the art would have immediately discerned that 5–500 microns is well within 2–1500 microns calculated by Petitioner using the parent applications’ claim 2. See Pet. 21–22; PO Resp. 16–17; Ex. 2003 ¶ 47. The numerical differences between the derived and claimed ranges do not address sufficiently why one of ordinary skill in the art would not discern the claimed range. See Pet. 20. As determined above, the disclosure would allow one of ordinary skill in the art to recognize that the claimed “distance from a center of one microfabricated structure to a center of a next neighboring microfabricated structure” has a range of values, such as the 2– 1500 microns calculated by Petitioner. See id. at 22.

We further agree with Petitioner that none of the derived pitch ranges aligns perfectly with the claimed pitch range. Pet. 21, 23; Ex. 1012 ¶ 120.
