      “Petitioner contends that a person of ordinary skill in the art, “[a]s of the claimed priority date of July 3, 2014, . . . would have been a person with a bachelor’s degree in electrical engineering or its equivalent and two years of experience in the field of electrical engineering including some experience in design of battery charging systems.” Pet. 21 (citing Ex. 1003 ¶¶ 19–30). Patent Owner “does not propose a different level of skill in the art[.]” PO Resp. 16. In light of the record before us, we adopt Petitioner’s proposal regarding the level of ordinary skill in the art, because it is supported by the testimony of C.

As neither party proposes an express construction for our consideration and because we determine that claim construction is not necessary, we do not expressly construe any claim terms.

      “arguments relating to whether the prior findings are “necessary to the determination” or whether estoppel applies to arguments relating to Richardson being inoperative. See Pet. Reply 27. Nor does Petitioner respond to our inquiry about whether collateral estoppel maybe applied on a limitation by limitation basis. See Pet. Reply 27. At the hearing, however, Petitioner confirmed that resolution of the issue is not necessary to our final determination. JUDGE ROSS: Do we even need to decide the collateral estoppel issue? I mean, it seems to me that if your petition clearly made out your case for the combination of Richardson and Zhao, then we don't even need to reach that. MR. CHANDRA: That’s exactly right, Your Honor. That is our position, as well. We believe collateral estoppel applies, but you don't need to decide that issue in order to find these claims unpatentable. As I mentioned before, these are the same references. We have fairly sought out all of the portions of Richardson, we cited to specific portions. Not just relying on collateral estoppel, but the teachings of the reference itself. So, while this is an issue, we believe that collateral estoppel should apply. It does not have to apply in order to find the challenged claims unpatentable. Tr. 19:9–20. We are persuaded, as discussed in Section II.G., that Petitioner has shown where Richardson in combination with Zhao meets each limitation of the claims of the ’203 patent. Accordingly, we need not address whether Petitioner has demonstrated sufficiently that collateral estoppel applies here.” slip op. at 14

    • 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. Petitioner’s alternative allegations based on Epower-20/Epower-21 are considered below.” slip op. at 18

We also find that the portions of Pogge cited by Petitioner show that its “void 25 has an important function in relieving stresses caused by differences in the thermal coefficient of expansion (TCE) of the various materials in and around the feature” (Ex. 1005 ¶ 27) and that the portions of Edelstein cited by Petitioner show that, “[a]lthough it does not change the thermal expansion coefficient, the introduction of a void or voids reduces the effective modulus and Poisson ratio of the through-via, resulting in a compliant through-via that exerts much less stress and force on the surrounding structures” (Ex. 1006 ¶ 47). As discussed above, we find that Cooney’s void 25 is “entirely surrounded by” its conductive filler 24 that, in turn, is surrounded by liner 22 and substrate 10’. Ex. 1004, Fig. 6. We credit Petitioner’s relied-upon testimonial evidence that the presence of a void was known to reduce thermal stress in the surrounding substrate, because the citations to the record support it. Ex. 1002 ¶¶ 124–134; Ex. 1005 ¶¶ 1, 9, 25–28, Fig. 2D; that “a void can decrease thermal stress in the substrate”). We agree with Petitioner’s declarant that Pogge provides a void in a TSV similar to Cooney and the ’609 patent. Ex. 1001, Fig. 4; Ex. 1002 ¶ 127; Ex. 1004, Fig. 6; Ex. 1005, Fig. 2D. We, thus, credit the testimony that, because of their common structural arrangements, one of ordinary skill in the art would have understood that stress-relieving characteristics in Pogge would have been manifested in Cooney’s void. Ex. 1002 ¶ 127. We also agree with Petitioner’s declarant that Edelstein includes a void in a TSV similar to Cooney, the ’609 patent, and Pogge.

      “And Patent Owner states that it “agree[s] with Petitioner’s construction” with respect to the MPF terms. PO Resp. 13. Although Patent Owner also contends that a “POSITA would understand the ‘means for transmitting’ to be a socket server transmitting through an event socket that implements the algorithms described in Figures 2, 3, 21A–21E and accompanying disclosures” (id.), Patent Owner’s proposed further construction is not disputed by Petitioner. See generally Pet. Reply. Furthermore, Petitioner’s proposed constructions of “socket” and “event socket” (Pet. 39) are not disputed by Patent Owner. PO Resp. 2, 13–14. In fact, by arguing that Spivey’s topic queues are neither “uniquely addressable” nor “communication endpoint[s],” Patent Owner appears to adopt Petitioner’s proposed construction of “socket” as a “uniquely addressable communication endpoint.” Id. at 2. As Patent Owner acknowledged during Oral Argument, “I don’t think there’s any dispute of what we mean by socket, a uniquely addressable communication endpoint.” Tr. 73:11–13.6 Thus, on this record, because there is no dispute between the parties regarding the terms “means for transmitting,” “event socket,” or “socket,” construction is not needed.

We find unavailing Patent Owner’s contention that Petitioner fails to “articulate why a POSITA would have been motivated to make the necessary modification and proposed combination.” PO Resp. 44. Here, Petitioner points out that its proposed combination would have been made to improve latency issues in Ellis’s system. Pet. 19–24.

Spivey also discloses pushing data to the “subscribed connected client devices” substantially simultaneously with the message queue server receiving the topic entry from a live data source, e.g., “with a time delay of 100 milliseconds or less,” which Spivey discloses is “at least two orders of magnitude shorter than conventional time periods of legacy devices.” Id. ¶ 96; see also id. at code (57) (disclosing pushing “the topic entry to a subscribed client device substantially simultaneously with the message queue server receiving the topic entry from a live data source”).” slip op. at 51

As Petitioner points out, although Patent Owner argues that there is a long-felt need for a system that “allows broadcasters to deliver synchronized, low-latency video and audio content. . . . ” (PO Resp. 66), Patent Owner does not contest Petitioner’s showing that Ellis also discloses “a video streaming system that provided event information over a separate channel, which is not hard embedded in the video stream.” Pet. Reply 22–23. Further, as Petitioner also points out, “claim 19 simply requires a media source to receive the live stream of digital content and distribute it.” Pet. Reply 23. In fact, during Oral Argument, although Patent Owner argues that its invention is “the synchronization and the latency improvements through that one-to-many socket architecture,” Patent Owner conceded that the claims “could be broader than that.” Tr. 44:24–46:16. We find availing Petitioner’s argument that the “claim language” does not “relate to any synchronized, low-latency, scalable, flexible, or new and improved video streaming technique.” Pet. Reply 23. Nevertheless, as Petitioner points out, Patent Owner does not cite to any evidence as to any long-felt but unresolved needs. Pet. Reply 23 (citing PO Resp. 67–68). In particular, Patent Owner merely provides conclusory statements that, prior to the claimed invention, “conventional video streaming systems” include “hard-embedded event information,” and that “[t]he claimed invention satisfied the long-felt need for an innovative system.” PO Resp. 66–68.

      “d) Analysis Re Construing “Voice Call Signals” We conclude that it is unnecessary to define “voice call signal.” Patent Owner’s construction would read into the term additional limitations that are for the most part already set forth in the claims: “a switchable mobile communications device capable of . . . voice call communication” (claims 1, 13, 21, 32); “output . . . a voice call signal for transmission . . . over a wireless network” (claims 13, 21, 32); “wherein the mobile communication device is a selected one of a wireless mobile phone and a personal digital assistant equipped with communication capability” (claims 12, 20, 31, 39).

      “This functional emulation solution is served regardless of how the specific RFID transceiver is implemented — the ’947 specification specifically provides for both software and hardware implementations. Id. at 2:24–28 (“Embodiments of the present invention includes . . . certain hardware and/or software embodied therein for the practice of the emulated RFID method”), 3:35–36 (“mobile communication device 102 is equipped with hardware and/or software elements”), 3:52–54 (“substantial portions of the hardware and/or software elements employed to provide a RFID”), 5:16 (“A Hardware/Software Implementation”). There is no reason why one version of the hardware used to emulate the RFID function could not be RFID transponder circuitry. The issue is not whether an RFID transponder can emulate itself, but rather whether RFID transponder circuitry incorporated into a mobile communications device can be used to allow the mobile communications device to emulate a separate RFID transponder. For example, rather than requiring the person described in the Background of the ’947 patent to carry both a mobile phone and a “key with remote control for gaining access to his/her vehicle,” they need only carry the mobile communications device of the claims. The statement in the ’947 patent that “the present invention is related to an emulated radio frequency data input method” (Ex. 1001, 1:22–24), and the other references to emulation, are consistent with a conclusion that the claims encompass the “functional emulation” option as described above.

Patent Owner contends that person of ordinary skill in the art: [W]ould have been someone “with at least a Bachelor’s degree in Electrical Engineering, Computer Science, or a related field, with a background in radio frequency communications and software development, as well as approximately two years of experience working with or researching radio frequency communication systems.

      “We agree with Patent Owner’s description of the characteristics and operation of a wireless mobile phone, which are not in dispute. Also, the Specification’s description of wireless mobile phones is relied on by Patent Owner in its arguments regarding the construction of “voice call signal,” as discussed below. Nonetheless, Petitioner argues that it is unnecessary to construe the term, “wireless mobile phone.” Reply 4. We agree. The term “wireless mobile phone” is only used in dependent claim 19 (not in independent claim 12, as Patent Owner alleges), and the principal reference relied on by Petitioner (Willgert) explicitly discloses the use of a mobile telephone. Ex. 1001, 12:2; Ex. 1004 ¶¶ 30–32.

      “to an emulated radio frequency data input method” (Ex. 1001, 1:20–21), and the other references to emulation, are consistent with a conclusion that the claims encompass the “functional emulation” option as described above. However, there is no basis for adding the negative limitation proposed by Patent Owner (“without the use of a physical RFID transponder”). Omega Engineering, 334 F.3d at 1333 (rejecting a construction because “neither the plain text of the claims, the specification, nor the file wrapper justifies the imposition of this negative limitation”). See also BillJCo, LLC v. Apple Inc., No. 2023-2189, 2023-2190, 2025 WL 1417957, at *1 (Fed. Cir. May 16, 2025): Our court has “identified claim constructions that exclude a particular element as including a ‘negative limitation’ and held that such exclusions must find support either in ‘the words of the claim’ or through an ‘express disclaimer or independent lexicography in the written description that would justify adding that negative limitation.’” Ethicon LLC v. Intuitive Surgical, Inc., 847 F. App’x 901, 907 (Fed. Cir. 2021). Patent Owner’s argument that the claim language, “[a] transceiver . . . configured to output . . . RFID transponder [signals or data],” only makes sense “if the transceiver is not itself an RFID transponder” (Sur-Reply 10) is not persuasive. Examination of the complete version of the passage that Patent Owner only paraphrases — “[a] transceiver configured to output voice call signals in the first state and to output RFID transponder signals in the second state” — shows that the transceiver is capable of both voice call and RFID functions, and thus there is no inconsistency in allowing the RFID function to be performed by RFID transponder circuitry incorporated into the transceiver.” slip op. at 24

      “teaching away. “A reference may be said to teach away when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). And, “teaching away” requires more than the mere expression of a general preference. Galderma Labs., L.P., v. Tolmar, Inc., 737 F.3d 731, 738 (Fed. Cir. 2013). Notably, our reviewing court has determined that a reference can distinguish prior art in order to show the novelty of an invention without teaching away from combining the prior art with the invention disclosed in the reference. See Ricoh Co., Ltd. v. Quanta Computer Inc., 550 F.3d 1325, 1332 (Fed. Cir. 2008). Here, Li prefers a “heterogeneous PN junction” and states that “a PN junction is prepared by a low-temperature deposition method, which avoids a conventional diffusion process at 800–1000°C. Such high-temperature process will cause more defects or contamination in silicon material, which will affect the improvement of cell efficiency.” Ex. 1008, 4. But, Li’s preference for lower temperature diffusion processes does not amount to a teaching away from the broader disclosure. In fact, Li acknowledges that “[t]he silicon thin film can be prepared by any deposition method,” including conventional processes at higher temperatures. Ex. 1008, 4 (emphasis added). And, while Patent Owner asserts that “[d]eposition methods are not relevant to the parties’ dispute, which is over deposition temperature” (Sur-reply 17), the deposition method employed includes its deposition temperature. Thus, just because Li teaches one way of depositing its silicon thin film using a low-temperature deposition method does not mean that Li teaches away from high-temperature processes. Li’s teachings do not discredit or discourage high-temperature processes in a manner that may be said to teach away.” slip op. at 44

      “We do not agree with Petitioner that the fact pattern before us is analogous to Rembrandt. The rationale to combine the teachings of Inoue and Smith provided in the Petition focuses on replacing incandescent bulbs with LEDs, and includes the generic statement that “[t]he numerous record-supported advantages, set forth in Smith provide a clear motivation for use of the teachings of Smith as applied to Inoue, so as to enjoy the advantages set forth in Smith.” Pet. 47. The testimony in Dr. Schubert’s Declaration at pages 99–100 cited in support of Petitioner’s Reply arguments was not cited or otherwise referenced in the Petition. See Pet. 46–55. We find that the Petitioner’s Reply is not responsive to the Institution Decision and is improper because it presents a new rationale to combine the teachings of Inoue and Smith that was not expressed in the Petition. See 37 C.F.R. § 42.23; CTPG § II.I. Petitioner could have presented its rationale to make out a prima facie case of unpatentability in the Petition. See 37 C.F.R. § 42.23; CTPG § II.I. Accordingly, we do not consider Petitioner’s new rationale to combine the teachings of Inoue and Smith presented for the first time in the Reply. Based on the entire record, but not including Petitioner’s new rationale and newly cited support to Smith and Dr. Schubert’s testimony (Exs. 1013, 1017) presented for the first time in the Reply, we are not persuaded that Petitioner sets forth in the Petition sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to one of ordinary skill in the art to modify the circuit of Inoue to include a light source or LED light source with a twinkling or flashing effect in view of Smith’s teachings. See Pet. 46–47, 49–50, 51–53, 55.

      “We observe that, aside from Declaration testimony of Mr. Altamura and accompanying exhibits, Patent Owner does not offer any additional evidence to establish reduction to practice. An inventor’s testimonial assertion of inventive facts requires corroboration by independent evidence. Brown v. Barbacid, 276 F.3d 1327, 1335 (Fed. Cir. 2002). The purpose of the corroboration requirement is to prevent fraud, by providing independent confirmation of the inventor’s testimony. Kridl v. McCormick, 105 F.3d 1446, 1450 (Fed. Cir. 1997). Without the requirement of independent corroboration, there would be a great temptation to commit perjury and the adverse party would be effectively precluded from a successful rebuttal. Price v. Symsek, 988 F.2d 1187, 1194–95 (Fed. Cir. 1993). A rule of reason applies to determining whether the inventor’s testimony has been corroborated. See id. at 1195. “The rule of reason, however, does not dispense with the requirement for some evidence of independent corroboration.” Coleman v. Dines, 754 F.2d 353, 360 (Fed. Cir. 1985). Accordingly, based on the entire record, we find that Mr. Altamura’s Declaration testimony is uncorroborated.

      “specification explicitly includes sensors similar to those in the prior art in support of their argument that the claimed “predetermined cycle” must not exclude the use of such sensors. Pet. Reply 15 (citing Ex. 1001, 32:55–33:7, 40:66–41:5, 44:9–29). We reviewed the portions of the specification cited by Petitioner. We agree with Patent Owner that one excerpt discussing sensor use appears to be directed to triggering the predetermined cycle rather than causing timing changes during the cycle itself (Ex. 1001, 32:55–66) (describing use of a pressure sensor to “determine when the vacuum channel 3 is clogged by a thrombus and automatically perform the unclogging procedures described herein”), while another excerpt discusses a sensor that Petitioner that the ’402 patent discusses the use of sensors to “tune” the system and that such “tuning” can be done statically (setting the cycle timing in advance) or dynamically (adjusting the timing during the cycle itself). See Ex. 1001, 48:19–49:50. Overall, we find that these disclosures involving sensors demonstrate that sensors may be used in various ways in different embodiments. However, none of these disclosures explicitly discuss the use of sensors in conjunction with a “pre-determined cycle.” Therefore, we find that the ’402 patent specification’s discussion of “sensors” are not particularly informative as to the appropriate construction of a “predetermined cycle” and do not outweigh the other explicit disclosures of “predetermined cycle” in the patent. We next turn to the other intrinsic evidence discussed by the parties — the prosecution history. As discussed by Patent Owner, in the Notice of Allowance, the Examiner found that Garrison did not teach or suggest a “predetermined cycle” because Garrison’s controller “changed the cycle of opening and closing the valves based on feedback from sensors.” Ex. 1004, 86. We acknowledge that the patent applicant filed subsequent comments during prosecution in which they stated that they “do[] not concede that the Examiner’s characterizations of the terms of the claims and the prior art are correct.” Id. at 29. However, we agree with Patent Owner that the importance of the Examiner’s statement in the Notice of Allowance does not rely on it being an express disclaimer (a standard which it does not meet). PO Sur-reply 8. We also considered Petitioner’s contention that the Examiner’s interpretation of Garrison may have been in error (PO Resp. 16); however, even if this were true, the Examiner’s statement still provides helpful insight into how the Examiner was interpreting the term sensors to change the opening and closing of valves during a cycle was not a “predetermined cycle.” Id. at 86. In sum, we find that Patent Owner’s proposed construction is consistent with the usage of the term “predetermined cycle” in the ’402 patent specification and prosecution history. Thus, after considering all of the cited evidence, we construe “predetermined cycle” to mean that “the timing of the sequence of valve operations in the cycle is determined beforehand, i.e., fixed, rather than varying based on feedback after operation begins.”” slip op. at 14

      “We agree with Patent Owner that neither Petitioner nor Mr. Brown propose any combination of Yang and Mullins that does not include Mullins’s pressure sensor in order “to control fluid flow in and out from the distal end of the catheter.” Indeed, in addressing the “predetermined cycle” limitation, Mr. Brown contends that Mullins discloses a “cycling controller that ‘varies aspiration pressure according to sensed pressure within the catheter lumen.’” Ex.1005 ¶¶ 131–32 (citing, e.g., Ex.1008, 27:40–28:20 (“[a] novel aspect of this pump system is the incorporation of feedback into the pump algorithm in order to produce more effective pressure cycling”)). This use of a sensor to change pressure during a cycle, is not a “predetermined cycle” under our construction. combinations is its discussion of distal end flow control, not for its sensors.” Pet. Reply 17 (citing Ex. 1035 ¶ 83). However, Petitioner’s obviousness grounds rely on the combination of Yang and Mullins, especially with regard to Mullins’s disclosure of “a controller” in order “to control fluid flow in and out.” As discussed above, Mullins relies on the sensor-feedback approach in order to control flow and we find that Petitioner has not presented persuasive evidence of how the combined disclosures of Yang and Mullins would control flow without using Mullins’s sensor feedback approach. See W.L. Gore & Assocs., Inc. v. Garlock, Inc., 721 F.2d 1540, 1550 (Fed. Cir. 1983) (error to “consider[] … references in less than their entireties, i.e., in disregarding disclosures in [them] … that diverge from and teach away from the invention”). Therefore, we determine that Petitioner has not sufficiently shown that the combination of Yang and Mullins discloses or renders obvious “a controller configured to open and close the vacuum valve and the vent valve in a predetermined cycle to change a level of vacuum at the distal end of the catheter and to control fluid flow in and out from the distal end of the catheter.” Accordingly, having considered the parties’ respective evidence and arguments, we find that Petitioner has not shown by a preponderance of the evidence that claim 1 of the ’402 patent would have been unpatentable as obvious over the combination of Yang and Mullins.” slip op. at 27
