      “Patent Owner does present some evidence of conception, diligence, and constructive reduction to practice, but Petitioner persuasively disparages that evidence on the preliminary record. For example, Patent Owner relies on April and May 2011 emails exchanged between two or more of the named inventors (Exs. 2027–2031, 2056, 2057, 2059) and a declaration from one of the named inventors, Dr. Nathan Moskowitz (Ex. 2024), to show conception of the claimed subject matter. Prelim. Resp. 8–61. Patent Owner also relies on Dr. Moskowitz’s declaration and emails (Exs. 2045, 2049, 2050) to show reasonably continuous diligence leading up to the filing of a provisional patent application. Id. at 63–66. Petitioner asserts that the documentary evidence does not show conception of the claimed “ridges,” in part, because a key email attachment regarding an embodiment for ridges has not been provided. Pet. Reply 1–4. Petitioner also asserts that Patent Owner’s relies on the declaration testimony from only one named inventor, which is vague and should be the subject of cross-examination. Id. Given these disputes, during trial, the parties are free to develop the record as to the asserted prior conception and diligent reduction to practice of the claimed subject matter, relative to Palmatier’s filing date.” slip op. at 3

      “In this proceeding, Petitioner persuasively shows, on the current record, that the ’790 patent is an AIA patent. As Petitioner notes, during prosecution of the ’790 patent, Patent Owner certified that the ’790 patent application “contains, or contained at any time, a claim to a claimed invention that has an effective filing date on or after March 16, 2013.” Ex. 1002, 246; see Pet. 11–12. Patent Owner, therefore, acknowledged that the application was to be examined under the first inventor to file provisions of the AIA. Id. Also, Petitioner shows, for purposes of institution, that the provisional applications to which the ’790 patent claims priority do not provide written description support for a “wearable device adapted to be placed on a wrist or a hand dorsal of a user,” such that the detection system of the wearable device has a “plurality of detectors arranged along an arc,” as recited in claim 2. Pet. 13.1 Although Patent Owner asserts that one of the provisional applications provides written description support via a figure illustrating a mouth guard design and a disclosure that “[t]he non-invasive devices may be part of a series of biosensors applied to the patient,” I do not find this persuasive based on the current record. See Paper 6, 16–17 (citing Ex. 1071, 15–16, 29, 40); Ex. 1071, 7, 29, 40. Even if the mouth guard could be considered to have detectors arranged in an arc, the mouth guard is used to “perform a non-invasive measurement for dental caries” and is not described as “adapted to be placed on a wrist or a hand dorsal of a user,” as claim 2 requires.

      “understanding of a person of ordinary skill in the art at the time the invention was made. See Graham, 383 U.S. at 17–18. Petitioners contend that a person of ordinary skill in the art (sometimes abbreviated herein as “POSITA”) would have had: at least a bachelor’s degree in electrical engineering, computer engineering, or computer science, and two years of experience in the field consumer electronics, with exposure to digital camera technology and wireless communications. Superior education could compensate for a deficiency in work experience, and vice-versa. Pet. 6 (citations omitted) (citing Ex. 1030 (Lett Decl.) ¶¶ 94–95). Because Petitioners’ proposed level of ordinary skill in the art appears to be consistent with the cited prior art and is undisputed on this record, we adopt it for purposes of this Decision. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (indicating that the prior art itself may reflect an appropriate skill level).” slip op. at 12

The petitioner ultimately bears the burden of persuasion to prove unpatentability of each challenged claim by a preponderance of the evidence. 35 U.S.C. § 316(e). This burden never shifts to Patent Owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015).

      “claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. 35 U.S.C. § 103; see also KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations including (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) when in evidence, objective evidence of nonobviousness.10 Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966). An obviousness determination requires finding a reason to combine accompanied by a reasonable expectation of achieving what is claimed in the challenged patent. See Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1367 (Fed. Cir. 2016). “[A]ny need or problem known in the field of endeavor at the time of invention and addressed by the patent can provide a reason for combining the elements in the manner claimed.” KSR, 550 U.S. at 419–20.” slip op. at 10
