    • BurdenDecided for patent owner

      “With respect to Petitioner’s allegations that rest on AAPA, we determine Petitioner has failed to show that claims 2, 10, and 11 are unpatentable. Our rules require that a petition for inter partes review must base the asserted challenges on “prior art consisting of patents or printed publications.” 35 U.S.C. § 311(b); 37 C.F.R. § 42.104(b)(2) and (4). And, a petitioner who relies on applicant admitted prior art as the basis, or part of the basis, of a ground, runs afoul of § 311. Qualcomm, 134 F.4th at 1365; see also USPTO Memorandum, Enforcement and Non-Waiver of 37 C.F.R. § 42.104(b)(4) and Permissible Uses of General Knowledge in Inter Partes Reviews (Jul. 21, 2025), available at www.uspto.gov/sites/default/ files/documents/aapa_memo_final__signed.pdf. We acknowledge but reject Petitioner’s position that its combinations discussing AAPA do not “rely” on AAPA but rather rely on U.S. Patent No. 5,793,185 (“the ’185 patent”), described in the ’203 patent as prior art. Pet. Reply 26. A petition for inter partes review must identify, “in writing and with particularity, each claim challenged, the grounds on which the challenge to each claim is based, and the evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3); 37 C.F.R. § 42.104 (b)(4). Here, Petitioner’s contention that the Grounds 2 and 5 actually rely on the ’185 patent when discussing AAPA is inconsistent with the Petition. In particular, the Petition does not cite to or direct our attention to any specific details from the ’185 patent to support its challenges. See generally Pet. 54–57, 76–77. Accordingly, Petitioner has failed to show, by a preponderance of the evidence, that claims 2, 10, and 11 would have been unpatentable over the combination of Richardson, Zhao, and AAPA as well as over the combination of Yu, Paparrizos, and AAPA.

      “information” should be given its plain and ordinary meaning as “data,” and that Patent Owner’s narrower construction of “first information” and “second information” lacks sufficient support in the intrinsic record. We agree with Petitioner that the ’802 patent Specification defines “information” as data when it uses the phrase “information (i.e., data).” See Ex. 1001, 5:60–62 (“Information (i.e., data) to be transmitted may be received in a baseband digital system 250, such as a wireless digital baseband processor.” (emphasis added)), 11:30–32 (“In this example, the signals 911 and 912 carry the same information (data).” (emphasis added)).

      “argument based on Fernandez alone, we find that Petitioner has not provided a sufficient evidentiary basis to support a motivation to remove the amplification from each of Fernandez’s signal generators 10A-10E and add a single power amplifier instead. See Pet. 76–77 Ex. 1003 ¶ 235. Petitioner’s only rationale for this modification to Fernandez is that “[a] single amplifier has several advantages compared to multiple amplifiers, including lower complexity, a single (vs. multiple) potential point of failure, and lower cost,” and that one of ordinary skill “would have found a single amplifier to be a simple matter of design preference.” Pet. 76–77. Dr. Almeroth simply repeats these cursory allegations without providing any further explanation or evidentiary support. Ex. 1003 ¶ 235. Moreover, Dr. Cooklev provides credible testimony that replacing Fernandez’s amplification in signal generators 10A–10E with a single amplifier would not necessarily have the advantages that Petitioner suggests. See Ex. 2013 ¶¶ 99, 104–105. For example, Dr. Cooklev testifies that a single amplifier would need to have a wider bandwidth than the multiple amplifiers used in Fernandez, which could cause potential stability issues. Id. ¶ 105. According to Dr. Cooklev, this wider bandwidth would require more circuit elements, and thus would not provide the reduction in space usage and power consumption that Petitioner asserts. Id. According to Dr. Cooklev, Montojo also points to several “substantial, and potentially impractical, drawbacks” of using a single amplifier for multiple signal generators, including power constraints imposed by spectral emission requirements and on-board battery capacity. Id. ¶ 104 (citing Ex. 1006 ¶¶ 7– 8).

      “We find credible and agree with Dr. Cooklev’s testimony that the predistortion signals from tables 17-1 and 17-2 “are cancelled out by Suzuki’s amplifier” 28. Ex. 2013 ¶ 50. Dr. Cooklev supports his opinion by referring to paragraph 1 of Suzuki, which states that Suzuki’s invention is directed to “a multi-band lookup table type predistorter” (such as the one implemented using lookup tables 17-1 and 17-2 in Figure 6) that “compensates for a distortion of a power amplifier.” Ex. 2013 ¶ 54; Ex. 1004 ¶ 1. Dr. Cooklev’s opinion is also supported by paragraph 3 of Suzuki, which explains that a conventional digital predistorter uses a lookup table “for linearizing non-linear characteristics of an amplifier.” Ex. 1004 ¶ 3; Ex. 2013 ¶ 54. Dr. Cooklev further supports his opinion by relying on Suzuki’s disclosure in paragraph 46 that power amplifier 28 is “subject to distortion compensation” by the predistorter, and that distortion components in the signal output by the amplifier are canceled by “distortion compensation data [that] are read out from the lookup tables 17-1 and 17-2 and provided to the adders 13-1 and 13-2, respectively.” Ex. 1004 ¶ 46; Ex. 2013 ¶ 54. And, Dr. Cooklev’s opinion is supported by Suzuki’s disclosure in paragraph 47 that the distortion compensation added by adders 13-1 and 13-2 add the distortion compensation data from lookup tables 17-1 and 17-2 “to perform distortion compensation (addition of predistortion)” to “signals to be transmitted.” Ex. 1004 ¶ 47; Ex. 2013 ¶ 54. Petitioner agrees that the distortion compensation data from lookup tables 17-1 and 17-2 “are added to the respective frequency band from” input signal ST “in order to predistort the output signal, which is then transmitted,” and does not dispute that the distortion compensation data from lookup tables 17-1 and 17-2 is ultimately cancelled out by the distortion created by amplifier 28. Pet. Reply 8. In light of the above evidence, we agree with Patent Owner that Suzuki’s distortion components from lookup tables 17-1 and 17-2 in Figure 6 (which Petitioner relies on for the first and second digital signals in limitations 10a and 10b) are cancelled out by the distortion created by power amplifier 28 before the signal is ultimately transmitted. We agree with Petitioner that these first and second digital signals include data in the form of distortion compensation data. However, because these signals are cancelled by the distortion from amplifier 28 before transmission, the data from these signals is never transmitted. Thus, the first and second digital signals identified by Petitioner (the distortion compensation data from lookup tables 17-1 and 17-2) do not comprise data “to be transmitted,” as limitations 10a and 10b require.” slip op. at 35

      “operatively linked to said electronic circuit” under 35 U.S.C. Section 112, sixth paragraph or not, the result is the same. We note there is no presumption of applying means-plus-function analysis to the switching element, because the limitation does not use the words “means for” that would mandate such claim construction treatment, and “switching” may invoke structure as well as function. See Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1349–1350 (Fed. Cir. 2015) (en banc) (holding that “use of the word ‘means’ creates a presumption that § 112, ¶ 6 applies”). Regardless, we look to the meaning of the claim phrase at issue in view of the specification. We determine that the ’294 patent provides a clear, concise meaning for the switching element upon which both parties rely for construction. Patent Owner’s express agreement with Petitioner, that the claimed switching element is described in the ’294 patent as “any type of device allowing data to be conveyed according to alternate data conveyance operations in response to an activation cue being received by transceiver 18 or not,’” is particularly telling because it is not consistent with Patent Owner’s argument that the switching element means “switching of the data.” Resp. 7, 31 (citing Ex. 1001, 9:28–318). The claim language does not recite, and the specification does not describe, the switching element as a device that switches the data.

Petitioner argues in reply that Patent Owner does not contest Petitioner’s mappings of Mooney’s “cordless telephone base unit” or “cellular network infrastructure” to the claimed data exchange devices, such that no construction is necessary to resolve the dispute. Reply 5 (citing Resp. 16–37; Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011)). Limitations [1.c] and [1.d] recite “a first [second] data transceiver operatively linked to said electronic circuit [in the cell phone],” both of which are defined functionally as “for exchanging data between said electronic circuit [in the cell phone] and a first [second] external data exchange device over a first [second] communication link.” Nothing in the the other independent claims, further limits the form or function of the “[external] data exchange device,” although a device external to the cell phone may invoke additional structure. We determine the plain meaning of “[external] data exchange device” as claimed and described in the ’294 patent governs: any [external] device that comprises an electronic circuit and data transceiver for exchanging data with the electronic circuit in the cell phone over a communication link. slip op. at 22

      “specification is the ‘single best guide to the meaning of a disputed term,’ . . . and ‘is, thus, the primary basis for construing the claims.’” Trs. of Columbia Univ. in City of New York v. Symantec Corp., 811 F.3d 1359, 1362 (Fed. Cir. 2016) (citations omitted). Although Patent Owner contends that the Specification disparages systems that impose significant restrictions on the possible choices of frequencies (PO Resp. 21), we find availing Petitioner’s contention that “[s]upport for Patent Owner’s construction is absent from the specification.” Pet. Reply 10. As Petitioner points out, Patent Owner’s claim construction “appears to be based on a single paragraph of the ’443 patent referring to preexisting ‘synchronization schemes [that] restrict the phase relationship and relative frequencies of the clocks.” Id. That is, the only reference by Patent Owner to the Specification is that the Specification states that “Some synchronization schemes restrict the . . . relative frequencies of the clocks, thereby eliminating the need for hardware arbitration [27]. Unfortunately, these schemes impose significant restrictions on the possible choices of frequences.” PO Resp. 26 (citing Ex. 1001, 6:32–36). We agree with Petitioner that such disclosure in the Specification “does not describe how these synchronization schemes ‘restrict the phase relationship and relative frequencies’ with any specificity.’” Pet. the Specification that some schemes impose restrictions on the possible choices of frequency is not a disparagement of any system that has limited choices of frequency or would preclude the claims from covering such prior art techniques. Instead, as Petitioner points out, the Specification of the ’443 patent states “[t]he preferred embodiment uses four domains […] so that domains may vary somewhat in size and still be covered by a single clock.” Id. (citing Ex. 1001, 5:57–59). As Dr. Baker testified in support of Petitioner’s contention, “the preferred embodiment of the ’443 patent relies on a single external master clock that distributes a signal to the local PLL of each domain.” See Ex. 1032 ¶ 9. Thus, although Patent Owner contends that clock signals generated based on a master clock cannot be interpreted to be generated independently of the clock signals generated for others of the plurality of domains (PO Resp. 49), we agree with Petitioner that such claim construction would “exclude[] the preferred embodiment of the ’443 patent,” which is disfavored. Pet. Reply 11. For the reasons discussed above, we conclude that “changeable independently” of the other domains does not require that the separate clocks in the plurality of domains be globally-asynchronous.” slip op. at 12

      “We disagree. Although claim 1 recites step 1b before step 1d, method steps are not ordinarily construed to require a specific order of performance unless the claims or Specification directly or implicitly require that specific order. See Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369–70 (Fed. Cir. 2003). Here, nothing in the express claim language precludes performing step 1d before step 1b. The claim does not expressly recite signaling the device(s) previously “identified as available.” Nor does the claim otherwise specify that step 1b must precede step 1d. For example, the claim does not contain temporal terms like “then,” “next,” or “further.” Although Patent Owner points out that a term of step 1d (i.e., “the” one more available devices) derives antecedent basis from step 1b, this alone does not require performing step 1b before step 1d. PO Resp. 5, 10; Sur-reply 11.

We agree with Petitioner and Dr. Terveen, that based on the teachings of Shiplacoff (and, by incorporation, Duarte), a person of ordinary skill in the art would have recognized that a flick started in area 102 or near an edge of screen 101 and continuing onto screen 101 would be distinguished from a flick entirely within screen 101 based on location, and would perform a different function. Ex. 1023 ¶¶ 18–19. We also agree with Petitioner and Dr. Terveen, that Duarte teaches associating a gesture with one function when a modifier key is not pressed, and associating the same gesture with a different function when the modifier key is pressed, such that a flick performed when the key is not pressed would perform one function such as scrolling and a flick performed when the key is pressed would perform another, such as changing the display mode. Reply 15 (citing Ex. 2003 ¶ 64; Ex. 1023 ¶ 20). We agree with Petitioner that Shiplacoff does not teach away from using a flicking gesture to change from full screen mode to home screen because it “does not criticize, discredit, or otherwise discourage investigation into the invention claimed.” Reply 10 (quoting Depuy Spine, 567 F.3d at1327).” slip op. at 25

    Claims 1–5, 7–15, 17, and 18 are unpatentable: claims 1–4, 9–14, 17, and 18 as anticipated by Tateishi, and claims 5, 7, 8, and 15 as obvious over Tateishi.

      “We discern no material difference between the parties’ definitions. Petitioner’s definition is consistent with the level of ordinary skill reflected in the prior art references of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (recognizing that the prior art itself may reflect an appropriate level of skill in the art). For purposes of this decision, we apply Petitioner’s definition of the person of ordinary skill in the art. We note, however, that were we to adopt Patent Owner’s assessment, the outcome of this Decision would be the same.” slip op. at 13

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

      “After considering the parties’ arguments and evidence, we determine that Patent Owner has not offered persuasive evidence that a person of ordinary skill in the art reading the claims in light of the Specification would understand the plain and ordinary meaning of “control signal” to be as narrow as Patent Owner proposes. We do not construe the claims such that the “control signal” must be the exclusively controlling factor of a component, as Patent Owner urges. Petitioner’s position, on the other hand, is consistent with the evidence of record. We construe “control signal” as having its plain and ordinary meaning, namely a signal configured to control a circuit component. D.

    • BurdenNot shown unpatentable

      “based on the Tateishi application publication (Ex. 1007), that the Tateishi Patent (Ex. 1005) also anticipates claims 1–4, 9–14, 17, and 18. See Pet. 23–24 (“The Tateishi Patent is also prior art under (pre-AIA) §102(e)”; identifying Ground 1 as anticipation “under §102 by Tateishi and/or the Tateishi Patent”). However, we are unable to locate in the Petition or Petitioner’s Reply a discussion of or citation to the Tateishi Patent other than under the Petitioner’s heading “Identification of Challenge and Relief Requested” on pages 23 and 24 of the Petition. Cf. id. at i–x (Table of Contents identifying a section of the Petition discussing the Tateishi (Application) anticipation ground but not a section discussing a Tateishi Patent anticipation ground). Although the issued patent may be substantively identical to the published application, Petitioner does not assert that, and we decline to compare the documents to determine whether that is the case. In light of Petitioner’s silence on the alternative ground, Petitioner has not demonstrated by a preponderance of the evidence that the Tateishi Patent anticipates 1–4, 9–14, 17, and 18.” slip op. at 47
