      “institute trial in a post-grant review. We institute a post-grant review only if the information presented in the petition filed under 35 U.S.C. § 321, if unrebutted, shows that it is more likely than not that at least one claim challenged in the petition is unpatentable. 35 U.S.C. § 324. On the existing record, we conclude that Petitioner demonstrates it is more likely than not that Petitioner would prevail in showing that at least one challenged claim of the ’781 patent is unpatentable under a presented ground.

      “STANDING Petitioner states that it certifies that: (1) the ’781 patent is available for post grant review because its earliest claimed effective filing date is October 9, 2018, and the patent issued less than nine months ago, on December 3, 2024; and (2) Petitioner is not barred or estopped from requesting a post grant review on the grounds in this petition. Pet. 5. This is sufficient. See 35 U.S.C. § 100(note)(A)–(B), § 321; 37 C.F.R. § 42.204(a). Patent Owner does not contest standing. See generally Prelim. Resp. B.

      “At this point, we find little meaningful difference between the two proposed definitions. In fact, neither does Patent Owner’s witness, Mr. Leinsing, who states that his “opinions would not change under either definition.” Ex. 2011 ¶ 42. And, as set forth above, Patent Owner asserts that, for the sake of its present arguments, it matters not which of the two proposed definitions we use for this proceeding. Prelim. Resp. 21. Thus, at this stage, we accept and use Petitioner’s proposed definition of the ordinarily skilled artisan, which, unlike Patent Owner’s, does not implicate reliance on the knowledge of people other than the individual ordinarily skilled artisan. Petitioner’s definition appears to comport with the level of skill in the art reflected in the prior art of record and the ’781 patent. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (“[T]he prior art itself [may] reflect[] an appropriate level” of ordinary skill in the art) (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed.

AWH Corp., 415 F.3d 1303, 1312–13 (Fed. Cir. 2005) (en banc). Petitioner indicates that None of the claim terms of claims 1–16 need to be construed to determine the patentability issues presented in this petition. The petition applies the ordinary meaning of the claim language as it would be understood by a POSA after reading the ’781 patent. Ex. 1002, ¶130. Petitioner will propose a construction if Patent Owner argues or the Board determines that one is required for any term. Pet. 31 (citing Ex. 1002).

      “III. CONCLUSION Because we determine that Petitioner has demonstrated a reasonable likelihood that it would prevail in showing at least one of the challenged claims is unpatentable, we institute inter partes review as to all challenged claims and grounds presented in the Petition. At this stage of the proceeding, we have not made a final determination as to the patentability of any of these challenged claims. ORDER For the reasons given, it is ORDERED that pursuant to 35 U.S.C. § 314, an inter partes review is instituted as to claims 1, 2, 5–8, 11, and 12 of the ’803 patent to determine whether: 1) claims 1, 5–7, 11, and 12 are unpatentable under 35 U.S.C. § 103 as obvious over TS 36.300, TS 36.321, and TS 36.331; 2) claims 1, 2, 5–8, 11, and 12 are unpatentable under 35 U.S.C. § 103 as obvious over Ericsson and TS 25.331; and 3) claims 5, 6, 11, and 12 are unpatentable under 35 U.S.C. § 103 as obvious over Ericsson, TS 25.331, and Sebire; and” slip op. at 27

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner

      “ordinary meaning, “primary” and “non-primary” cells are all cells that the WTRU is connected to (PO Resp. 16), the plain language in claim 1, and similarly in claim 7, does not require a “primary” node or “non-primary” cell to have a connection to the WTRU. See Ex. 1001, 10:38−56; 11:11–26. We find unavailing Patent Owner’s contention that the claims require that the WTRU “be connected to more than one cell,” wherein cells that are “associated with a wireless network node,” but are not connected to the WTRU “at the same time” cannot be “primary” or “non-primary” cells. PO Resp. 16. In the ’803 patent, nothing in the Specification clearly limits “primary” and “non-primary” cells as Patent Owner proposes. Prelim. Resp. 16. Patent Owner points to the Specification of the ’803 patent to show that, for softer handover, the WTRU is connected “with more than one cell [] which are controlled by the same Node-B,” and “[o]ne of the[se] cells 808 may be designated as a primary cell 808a, while other cells are designated as a non-primary cells 808b.” Id. (alterations in original) (citing Ex. 1001, 8:44–46, 9:4–6, Figs. 8A–B). However, this portion of the Specification (describing a softer handover embodiment in which a cell “may be designated” as a primary while other as non-primary) does not provide a clear definition to warrant interpreting the “primary” and “non-primary” cells as requiring “connection” to the WTRU “at the same time.” Id. That is, nothing in the Specification clearly precludes “primary” and “non-primary” cells from being “source” and “target” cell, as Patent Owner contends. PO Resp. 16. and the Specification, we determine that the terms “primary” and “non-primary” recited in claims 1 and 7 are not limited to cells connected to a WRTU at the same time. We determine no further explicit construction of this term is necessary to resolve the controversy. See Vivid Techs., 200 F.3d at 803.” slip op. at 8

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundInstituted

      “f) Motivation to combine Ericsson and TS 25.331 Petitioner contends that a “POSITA would have been motivated to combine Ericsson and TS 25.331 because they are directed to similar technologies and a skilled artisan would have understood the benefits of combining these two references,” and “would have understood that there was a high likelihood of success in making the combination.” Pet. 34 (citing Ex. 1003 ¶¶ 156–157). In particular, the references “are both reasonably pertinent to the problem faced by the inventor, namely protocols for handover in a telecommunications system.” Id. (citing Ex. 1003 ¶ 158). According to Petitioner, the combination “involves the predictable use of interchangeable prior art elements according to their established functions” more than routine engineering.” Id. at 37 (citing Ex. 1003 ¶ 174). At this stage of the proceeding, Patent Owner does not present arguments in the Preliminary Response addressing the specific merits of Petitioner’s contentions with respect to the motivation to combine Ericsson and TS 25.331. See generally Prelim. Resp. 15–18. We find availing Petitioner’s contention that Ericsson and TS25.331 are “directed to similar technologies,” and that a “skilled artisan would have understood the benefits of combining these two references.” Pet. 34. On this preliminary record, we are persuaded that Petitioner has made a sufficient showing that a POSITA would have had a reason to combine the teachings of Ericsson and TS 25.331.” slip op. at 20

At this stage in the proceeding, Patent Owner does not contest Petitioner’s proposal or offer an alternative.

      “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.

    • 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

Moreover, in accordance with our rules, “[w]hen instituting inter partes review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” 37 C.F.R. § 42.108(a) (2024); see also PGS Geophysical AS v. Iancu, 891 F.3d 1354, 1360 (Fed. Cir. 2018) (interpreting the statute to require “a simple yes-or-no institution choice respecting a petition, embracing all challenges included in the petition”). Applying those standards, and upon considering the Petition, the Preliminary Response, and the evidence of record, we determine the information presented a reasonable likelihood that Petitioner would prevail in establishing the unpatentability of at least one of the challenged claims of the ’639 patent. Accordingly, we institute an inter partes review.” slip op. at 2

      “We find that Petitioner has shown sufficiently on this record that the combination of Fakoorian-1 and Takahashi teaches limitations [1d] and [1e]. See Pet. 21–28. As Petitioner argues, Fakoorian-1 includes multiple SPS configurations and teaches that configuration parameters, related to a first and a second SPS configuration, may be sent to the UE in one or more RRC messages. See Pet. 21, 23–24. These parameters include a “periodicity,” “CS-RNTI,” “HARQ process number,” and “service type.” Id. at 21, 24. Petitioner has also shown sufficiently, based on the testimony of Dr. Mandayam, which at this stage stands unrebutted, that a person of ordinary skill in the art would have understood that a “HARQ process number” is “used to indicate which [SPS] configuration(s) are to be” released, and Fakoorian-1’s UE acknowledges the “release by transmitting the acknowledgement in a codebook through a physical uplink control channel (PUCCH) resource.” Id. at 23. As Dr. Mandayam testifies, a person of ordinary skill in the art would have understood, based on Fakoorian-1, that a HARQ process number indicates an identifier for the HARQ codebook to be used by the UE to transmit the acknowledgment.

      “Regarding spatial diversity, Dou explains that a first internal antenna and a second internal antenna “may be separated by a distance (D) that is no less than the quarter wavelength (>=λ/4) of the lowest frequency.” Ex. 1013 ¶ 24; see Ex. 2010 ¶¶ 35, 44. Consistent with Dou’s preference for at least a quarter-wavelength spacing between antennas at the lowest frequency, “a commonly accepted rule of thumb is that at least a quarter-wavelength spacing between antennas is necessary to provide effective spatial diversity.” Ex. 2010 ¶¶ 33, 35, 47. Effective spatial diversity requires sufficient spacing between antennas because that technique “uses multiple antennas to improve signal reliability and performance by mitigating the effects of multipath fading and other interference.” Ex. 2010 ¶ 33. “Multipath fading occurs when a wireless signal propagates along multiple different paths of differing lengths because of interactions with obstacles, resulting in portions of the signal energy arriving at a receiver with different phases slightly offset in time.” Id. Locations insufficiently separated in terms of wavelength “tend to experience similar fading and interference characteristics.” Id. Thus, closely spaced antennas “cannot provide effective spatial diversity.” Id. By providing sufficient spacing between antennas, however, “the likelihood increases that at least one of the antennas will be positioned at a location where the multipath or other interference is relatively low, thereby improving overall signal quality and reliability.” Id. As Patent Owner contends, the proposed combination modifies Dou’s ground plane 310 to replicate Jing’s ground plane with dimensions of 36 mm × 60 mm and limits “the extent of Dou’s ground plane 310 so that it [does] not extend behind Jing’s antenna at 306, just like Dou does not extend it behind antenna 308.” See Pet. 35–36; Prelim.
