      “Network LLC, 929 F.3d 1350, 1357 (Fed. Cir. 2019). On its face, the language “energy transfer signal” does not specify any restrictions on the type of system in which it is utilized, nor its characteristics. In the context of claims 1 and 11, the “energy transfer signal” is the basis on which the “switch” operates, so as to “sub-sample and transfer energy from a first electromagnetic (EM) signal.” Ex. 1001, 50:63–65, 51:56–58. Accordingly, based on the claim language, the term “energy transfer signal” need only be a signal for operating a switch to sub-sample and transfer energy from an electromagnetic signal.

      “’686 patent broadly includes knowledge and experience as to RF circuit design. See supra § III.B. Petitioner contends that “Nevo’s transceivers [102a/102b] are for Bluetooth and IEEE 802.11,” and that a person of ordinary skill in the art would have understood that both protocols “required down-conversion in their receivers to obtain a baseband signal.” Id. at 35 (citing Ex. 1004, 4:45–50; Ex. 1002 ¶ 118). Nevo’s disclosure would have motivated a person of ordinary skill in the art to look to Avitabile, which provides the circuit level detail for down-converters. See Ex. 1006, Abstract. Avitabile specifically provides circuitry for down-conversion in the s-band frequency range, which is in the range of Bluetooth and IEEE 802.11 (2.4 GHz). Id. at Abstract, Figs. 6, 7. Accordingly, we determine a person of ordinary skill in the art would have been motivated to look to down-converters in the range of frequency needed, and would have been motivated to combine Avitabile’s teachings with those of Nevo, with a reasonable expectation of success.” slip op. at 55

Patent Owner contends that a POSITA would have at least: (a) a bachelor’s degree in electrical engineering, optical engineering, or a related field; (b) two years of practical experience in designing and developing lighting systems, particularly those integrated with electronic devices such as webcams or computer monitors; and (c) knowledge of user-interface considerations for consumer electronics . . . . Additional experience can substitute for education and vice versa. Prelim. Resp. 12 (citing Ex. 2036 ¶ 48). Patent Owner disputes Petitioner’s contentions regarding what a POSITA would have understood. Prelim. Resp. 12–13 (“[O]ne of ordinary skill in the art would have understood that analog and digital cameras have different operating principles and lighting requirements [and] Petitioner’s lack of appreciation for the suitability and unsuitability of different lights for different applications infects and dooms its invalidity analysis.” (citing Ex. 2036 ¶¶ 36–47)). and years of experience required for a POSITA.

      “Dr. Papanikolopoulos’s testimony that Kuwata teaches away from modifying its camera 22 to access an external server (such as Fisher’s Internet-enabled external data source) by stressing advantages of a self-contained camera-printer pair without external dependencies. See PO Resp. 15–16, 26–28 (citing Ex. 1005 ¶¶ 75, 77); Ex. 2001 ¶¶ 61–64. The cited disclosures in Kuwata simply do not discuss any advantages arising from a self-contained camera-printer pair without external dependencies, or any disadvantages arising from connecting camera 22 to an Internet server. See Ex. 1005 ¶¶ 75, 77. The cited disclosures instead tout the advantages arising from a camera manufacturer (rather than an end user photographer) specifying the image output control information CI for a specific camera-printer pairing, to reduce differences between an image as confirmed by the end user on the camera’s display and the image outputted by the printer. See id. That advantage, however, has nothing to do with whether camera 22 may or may not communicate with an Internet server. Indeed, rather than being self-contained as Patent Owner and Dr. Papanikolopoulos would have it, we find Kuwata’s camera 22 includes an I/O port for wired or wireless communication to transmit the camera’s image files GF / 10 to various printers 24 and various personal computers (PCs). See Ex. 1005, Fig. 4, ¶¶ 81, 85; Ex. 1003 ¶ 84; Pet. 14. Thus, Kuwata allows for and does not discourage communication between camera 22 and an Internet server such as Fisher’s external data source. In particular, Kuwata does not detract from the benefits of updating image output control information CI after the camera is manufactured, for example so that the camera can be paired with printers that were not yet on the market when the camera was manufactured. Moreover, Fisher recognizes that “a manufacturer may create various ancillary data files 418, and make the ancillary data files 418 available on a distributed computer network like the Internet for subsequent downloading and utilization by camera device 110.” Ex. 1006 ¶¶ 42, 55.

We acknowledge the ’807 Patent Specification discloses the words “the specific object” in the context of acknowledging or detecting the specific object in the image with the object acknowledgement section and retrieving an image from the database that contains the specific object after keywords are added to the image. See Ex. 1001, 4:18–24, 5:54–6:3, 7:28–31. Similarly, the Specification discloses the term “specific person” in the context of retrieving an image from the database that contains the specific person after keywords are added to the image. See Ex. 1001, 4:48–54. We further acknowledge that the Specification discloses a face image similarity determining section to determine if a face image is similar to a face image stored in the database.

Finally, we also acknowledge that the Specification further discloses an example of a database record that includes keywords, such as “Jiro” and “second eldest brother” for a human, and further discloses retrieving items from the database with the keyword “Jiro.” See Ex. 1001, 9:47–54, 10:41–58, Figs. 6, 9. however, do not rise to the level of disclaimer or a disavowal of the full scope of the claim term “similar to the object of the image previously contained in the database.” For example, Patent Owner does not direct us to any explicit statements or disclosures in the ’807 patent Specification that indicate a clear intention to limit “similar to the object” to “sufficiently similar to identify the specific object” using words or expressions of manifest exclusion or restriction.

      “We disagree with Patent Owner. Patent Owner argues that Petitioner’s reliance on Yadav (Ex. 1009) is improper because Yadav “was not published until May 16, 2013, more than three years after the priority date of the ’638 patent.” However, under 35 U.S.C. § 102(e)(1), a published patent application, such as Yadav, is deemed to be prior art as of its filing date, not its publication date as Patent Owner asserts. See Lynk Labs, Inc. v. Samsung Elecs. Co., Ltd., 125 F. 4th 1120, 1126–27 (Fed.

      “A. Legal Standards — Petitioner’s Burden “In an [inter partes review], the petitioner has the burden from the onset to show with particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (citing 35 U.S.C. § 312(a)(3) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the 1 Amendments to 35 U.S.C. § 103 enacted by the Leahy-Smith America Invents Act, Pub. L. No. 112-29, 125 Stat. 284 (2011) (“AIA”) took effect in March 2013. The ’353 patent issued from an application filed in September 2004. See Ex. 1001, code (22). Thus, we apply the pre-AIA version of § 103. grounds for the challenge to each claim”)). This burden of persuasion never shifts to the patent owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). B. Legal Standards — Obviousness A patent claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. 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) objective evidence of nonobviousness, if made available in the record, which has not happened here.

Level of Ordinary Skill in the Art Petitioner contends a person having ordinary skill in the art pertaining to the ’353 patent “would have possessed at least a four-year degree in physics, biophysics, medical physics, or a related field, and two years of experience in developing and/or applying computed tomography methods,” wherein “[a]dditional education and professional experience are interchangeable.” Pet. 1; Ex. 1003 ¶¶ 54–55. “Patent Owner utilizes Petitioner’s proposed level of skill in the art.” Prelim. Resp. 2. For purposes of this Decision, we adopt Petitioner’s formulation of ordinary skill in the art, as it appears to be consistent with the ’353 patent and the asserted prior art. See Okajima v.

    • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted

      “(iii) Analysis Based on the present record, we determine Petitioner’s contentions regarding the third step of claim 1 are supported sufficiently by the cited disclosures in Weese and Dr. Peterson’s testimony to justify institution of review. In particular, Weese describes obtaining a plurality of second images of the patient’s internal organs (i.e., PET image I0 in Fig. 1, and PET image I10 in Fig. 3) using a second imaging technique (i.e., PET). See Ex. 1005, Figs. 1, 3, and 6, ¶¶ 47–49, 58–59, 72. In particular, PET image I0 in Figure 1 may be a reconstructed “volume image[]” composed of a plurality of “quasi two-dimensional” “slice images” that, when combined, represent a three-dimensional region inside the patient. Id. ¶¶ 48, 58, 61; see also Pet. 56–57. PET image I10 in Figure 3 may be a similarly reconstructed volume image composed of a plurality of slice images.4 See 4 We do not rely here on Petitioner’s alternative theory that Weese discloses a “plurality” of second images because PET images I0 and I10 are “superposed” images encompassing “several states of motion.” Pet. 58. Ex. 1005 ¶¶ 61, 83–84. Patent Owner’s sole opposition to Petitioner’s assertions in this regard are limited to whether Weese “obtain[s]” PET images I0 and I10 as recited in claim 1, which we address below. Also, it appears that PET images I0 and I10 are obtained while also obtaining second movement measurements of the patient’s internal organs using a second sensor system (i.e., motion acquisition unit 12 and motion sensor 15 / S1) which is independent from the PET imaging technique. See Ex. 1005, Figs. 1 and 6, ¶ 65 (“[T]he respiratory motion is determined during the acquisition of the PET projections P1 by means of a respiratory motion sensor provided on the patient and therefrom the frequency function f(r) or, more generally, a state of motion function F1 is derived for the construction of the motion model M2.”). Furthermore, Weese describes how frequency function f(r) is utilized to facilitate image comparison between CT and PET images at common motion states. See id. ¶¶ 31, 49–51, 70–71, 75–77, 79–80, 83; see also Ex. 1003 ¶¶ 214–216 (Dr. Peterson’s supporting testimony). Patent Owner’s sole opposition to Petitioner’s assertions in this regard are limited to whether Weese “obtain[s]” PET images I0 and I10 as recited in claim 1, which we address below. Patent Owner’s two opposing arguments are unavailing, based on the present preliminary record. First, Petitioner relies on reconstructed PET images I0 and I10 as satisfying the “plurality of second images” recited in claim 1, not PET projections P1 from which PET images I0 and I10 are derived. See, e.g., Pet. 56, 58 (“I0 and I10 disclose and render obvious a ‘plurality of second images’ in two ways” — “I0 and I10 may be ‘volume images’ formed using ‘known’ techniques,” and “I0 and I10 are ‘superposed’ PET images encompassing ‘several states of motion,’ which” slip op. at 18

Alternatively, a POSITA would have at least two years of undergraduate training in a physical science (e.g., engineering or physics) and at least four years of practical experience designing lighting systems. Pet. 10 (citing Ex. 1004 ¶¶ 31–32). Patent Owner did not file a Preliminary Response. For the purposes of this Decision, we apply Petitioner’s currently uncontested definition except for the term “at least” because it may cause ambiguity resulting in potentially encompassing those with more than ordinary skill in the art. With that qualification, Petitioner’s proposal appears consistent with the problems addressed in the ’373 patent and the prior art.” slip op. at 10

When evaluating a prior art reference in the context of anticipation, the reference must be “considered together with the knowledge of one of ordinary skill in the pertinent art.” In re Paulsen, 30 F.3d 1475, 1480 (Fed.
