    “bears pointing out that the specification of the ’138 patent appears to explain what “a single allocation” means: If there are multiple QoS requirements within a single 3GPP PDP context, a single physical allocation of radio resources may be made to the UE. In this manner, a single PDP context implies a single CCTrCh. This single physical allocation of radio resources provided to a UE is shared amongst a number of services, in proportion to their respective QoS requirements, for example in proportion to the signalled weight values (Stier). Ex. 1001, 9:36–43 (emphasis added). Petitioner’s expert, Dr. Ding, explains that the “abbreviation CCTrCh was understood in the art to refer to a transport channel known as the Coded Composite Transport Channel.” Ex. 1003 ¶ 88. Dr. Ding testifies that Eckert teaches selecting data for uplink within a determined TTI and scheduling the uplink transmission on a transport channel, E-DCH, where scheduling of the E-DCH in a UE is controlled by a base station. Eckert, [0012] (“[A] new dedicated transport channel called Enhanced Dedicated Channel (E-DCH) has been introduced for this purpose. The fundamental characteristics of this new transport channel include . . . scheduling controlled by the base station, also called NodeB in UMTS…” Id. ¶ 90.

In assessing the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

    “Here, in our opinion, Patent Owner has shown that the Specification describes the potential destinations of a vehicle as limited to physically fixed, non-transient objects or features. PO Resp. 18–21. As an initial matter the ’805 patent is titled “Docking Assistant” and explains its purpose for guiding a “vehicle to a stop at a specific location.” Ex. 1001, codes (53), (57), Abstract. We acknowledge that claim 1 does not expressly recite that “at least one potential destination” is a fixed destination or location. See id. at 7:61– 63 (Claim 1 requiring “extracting from the acquired image data positional parameters of at least one potential destination relative to the motor vehicle;”). Yet, in the context of the relatively brief specification, there is no explanation, example, or embodiment which reasonably extends the meaning of “destination” or “potential destination” beyond a fixed location. The ’805 patent describes in the Abstract that [m]any day-to-day driving situations require that an operator of a motor vehicle guide the motor vehicle along a specific course and bring the vehicle to a stop at a specific location, for example in a parking bay or at a loading platform. Id. at code (57) Abstract. The Abstract explains in the next sentence that “[t]o assist a vehicle operator in such situations, a method and a suitable device for implementing this method, include detecting the potential target objects in the image data of an image sensor and identifying the potential target objects as potential destinations in a multi-stage exclusionary method.” Id. (emphasis added). Nowhere in this initial description of the invention, nor anywhere else that Petitioner points to, is there is expansion of the “specific location” or “potential destination” beyond a docking station or parking bay. Of course, the claim is not limited to these examples, as it would be inappropriate to read in such limitations from the Specification. See Acceleration Bay, LLC v. Activision Blizzard Inc., 908 F.3d 765, 771 (Fed. Cir. 2018) (“Acceleration again attempts to import structural limitations into claims lacking those limitations. . . .

    “Patent Owner’s declarant, Dr. Majumder, testifies to the contrary that “[r]ead as an engineer, the ‘805 patent’s present invention is framed around guiding a vehicle to fixed, physical destinations (exemplified by docking stations and similar structures) without fiducials or special markings.” Ex. 2010 ¶ 81. Considering Broggi, Dr. Majumder testifies further that “[a] moving object, such as a preceding car, is not a valid destination under the ‘805 Patent, because it is not a stationary location at which the host vehicle can be guided to stop. To treat such a vehicle as a ‘potential destination’ would lead to collision, not guidance.” Id. ¶ 86. As discussed in our claim construction, given a plain reading of claim 1 in light of the Specification, our understanding of the ’805 patent is consistent with Dr. Majumder’s testimony. We agree that Broggi is directed expressly to the platooning of moving vehicles, and not physically fixed destinations as the proper claim construction requires. Because Broggi does not disclose the use of physically fixed “potential destinations” as required, e.g., in limitations [1.2]–[1.3], and neither Huttenlocher nor Brady are relied upon to overcome this deficiency, Petitioner has not met its burden of persuasion to show by a preponderance of the evidence that claim 1 would have been obvious over Broggi in view of Huttenlocher and Brady.” slip op. at 27

This is consistent with our determination that “electrode stack” is a conductor that provides a path for current entering or leaving a medium such as a semiconductor device We disagree with Patent Owner that “electrode stack” as used in the challenged claims should be limited to the specific electrodes shown in the embodiments described in the Specification. See PO Resp. 4–9. Although the Specification describes embodiments using source, drain, and Schottky gate electrodes as electrical contacts, we see no reason to construe the term “electrode stack” itself to be limited to these components as Patent Owner proposes. Claims 1 and 13 expressly recite that electrode stacks comprise the claimed “electrical contact,” without expressly including or precluding any specific type of electrode. Ex. 1001, 5:54–63, 6:37–47. The Federal Circuit advises that the Specification “is not a substitute for, nor can it be used to rewrite, the chosen claim language. ‘Specifications teach.

Neither Petitioner nor Dr. Zhao, however, provide adequate explanation or evidence as to why Usui’s interconnect metallurgy structure forms an “electrode stack,” i.e., a conductor that provides a path for current entering or leaving a medium such as a semiconductor device. Dr. Zhao’s testimony merely repeats the disclosures in Usui and concludes, without further technical detail, explanation, or reference to objective evidence, that Usui’s Figure 8 discloses an electrode stack. Ex. 1002 ¶¶ 89–91. Dr. Zhao’s testimony sets forth Petitioner’s conclusory assertions as though they are facts, rather than setting forth facts and evidence in support of those assertions.

Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). In contrast, Patent Owner’s declarant Dr. Piner testifies, with evidentiary support, that interconnects (such as Usui’s interconnect metallurgy structure) and electrical contacts (such as that claimed in the ’562 patent) are not the same thing. See Ex. 2024 ¶¶ 63–70. For example, Dr. Piner explains: In other words, not all metals in a semiconductor device have the same purpose and could not be said to be interchangeable. By August 2009 it was well known to a POSA how to discern if a metal component in a transistor is an interconnect or serves as an electrical contact such as a gate contact or ohmic contact, based on the structure and functionality of the metal component. For example, interconnects are made up of metal strips and are deposited on insulators. EX-1011 (Mishra) at 216. Interconnects are low resistance conductors that can carry very high current densities. Id., 216, 217. Unlike Schottky contacts and ohmic contacts, interconnects do not provide non-linear IV response like Schottky contacts nor inject electrons and holes into semiconductors like ohmic contacts. Id., 218. As many of the references cited by Dr. Zhao illustrate, electrical contacts had their own highly complex design challenges. EX-1008 (Pearton), 41-59 (Pages 53-71 of 383) (discussing electrical contacts); EX-1017 (Kramer), 11-126 (Pages 18-130 of 151) (same). And while Dr. Zhao cites these as supporting a POSA’s knowledge of an electrical contact, none of these references describe electrical contacts as interconnects. Id. ¶ 71. Dr. Piner further testifies that Usui’s interconnect metallurgy structure is an interconnect, and not an electrical contact, because “Usui states that ‘[t]he structures fabricated by the process of the present invention are especially useful for forming electrical connections or wiring such as between active and/or passive devices of an integrated circuit structure.’” Id. ¶ 148 (citing Ex. 1004, 1:11–14) (alteration in original); see also id. ¶¶ 150– 151 (Dr. Piner testifying that Usui’s interconnect metallization structure is not an “electrode stack” under a broad definition of electrode).

After reviewing the complete trial record, we are not persuaded that Petitioner has done so. Petitioner relies on the testimony of Dr. Zhao to support its contention that the identified layers in Usui’s interconnect metallurgy structure form an “electrode stack including a plurality of metal layers and a capping layer formed over said plurality of metal layers” as recited in claim 1.

    “apparent agreement between the parties: “TPC command accumulation” refers to a process that collects and uses TPC commands from a network device to cumulatively affect transmission power. And having studied the intrinsic record of the ’153 patent, we are in accord. But, we decline to further limit the construction of “TPC command accumulation” in the manner proposed by either party––i.e., (1) each TPC command adjustment must be summed to cumulatively affect transmission power (as proposed by Petitioner) or (2) a TPC command value must be added to an integrator. Although both parties are able to point to disclosures in the ’153 Patent where the TPC command accumulation of an exemplary embodiment is described as using an integrator and/or summing each TPC command adjustment to cumulatively affect a UE’s transmission power (PO Resp. 16 (citing Ex. 1001, 3:39–43, 7:15–29, 9:27–42; Ex. 2016 ¶¶ 35–42); Pet.

On the other hand, an obviousness analysis “need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.” Id. at 418; accord In re Translogic Tech., Inc., 504 F.3d 1249, 1259 (Fed.

Instead, a petitioner must articulate a reason why a person of ordinary skill in the art would have combined or modified the prior art references. In re NuVasive, Inc., 842 F.3d 1376, 1382 (Fed. Cir. 2016); see also Metalcraft of Mayville, Inc. v. The Toro Co., 848 F.3d 1358, 1366 (Fed. Cir. 2017) (“In determining whether there would have been a motivation to combine prior art references to arrive at the claimed invention, it is insufficient to simply conclude the combination would have been obvious without identifying any reason why a person of skill in the art would have made the combination.”); Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015) (“[O]bviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed invention.”) (citing InTouch Techs., Inc. v. VGO Commc’ns, Inc., 751 F.3d 1327, 1352 (Fed. Cir. 2014)). In arguing for the obviousness of claim 1 over the combination of Bonn and Mizuta, Petitioner argues that a person of ordinary skill in the art would have modified Bonn to perform high-frequency signal amplification. Pet. 19–25. In particular, Petitioner argues that a person of ordinary skill in the art “would have found it obvious to modify the circuit of Figure 1 [of Bonn] and use Figure 7’s structure for high frequency signal amplification in place of mixer 40,” followed by additional modifications to the circuit of Figure 1. Id. at 22–25. These additional modifications include removing LO port 55, removing FET 20 (along with voltage source 80, capacitors 16, 26, and 34, resistor 18, and inductors 22 and 24), removing capacitor 34 and shorting gate structure 324 to ground, and removing resistors 46 and 48 and shorting terminal 51 to ground. Id. According to Petitioner, the motivation for these modifications was that “Bonn . . . teaches using its dual gate structures for signal amplification without signal mixing.” Id. at 22 (citing Ex. 1006, 11:26–37). On the record developed at trial, we disagree. Bonn does, as Petitioner argues, teach that “the dual gate FET structure of the present invention can be tailored to provide superior performance over the prior art dual gate FET structures in high frequency signal mixing as well as other applications such as high frequency signal amplification.” Ex. 1006, 11:33–37. But the tailoring that Bonn refers to relates to changes to the structure of the field-effect transistor itself, not to the circuitry surrounding that transistor. Id. (teaching that the reason that “the dual gate FET structure of the present invention can be tailored” is that “the parameters such as gate width, dopant concentration, and channel depth, under each gate of the dual gate FET are individually adjusted for optimum performance”). Thus, although Bonn might have motivated a person of ordinary skill in the art to have made changes to the dual-gate FET itself, we are not persuaded that it would have motivated the additional changes to the circuit of Bonn’s Figure 1.” slip op. at 11

  • Strike new argumentNew argument disregardedDecided for patent owner

    “Mishra’s Figure 5 is a second gate in favor of a new position. Petitioner’s new argument is that a person of ordinary skill in the art would have found it obvious to connect the field plate of Mishra’s Figure 5 to the source instead of the gate, converting the field plate into a second gate. Compare Pet. 83 (equating “drain side gate” with “field plate 66, Figure 5”), 86–88 (identifying field plate 66 as a “second gate”), with Reply 21–22 (identifying only the embodiment of Mishra’s Figure 10 as a source-connected field plate), 22–23 (arguing that Mishra teaches that the Figure 5 embodiment “could be arranged as ‘a single transistor with a dual gate structure’”). Although “the introduction of new evidence in the course of the trial is to be expected in inter partes review trial proceedings,” Genzyme Therapeutic Prods. LP v. Biomarin Pharm. Inc., 825 F.3d 1360, 1366 (Fed. Cir. 2016), the shifting of arguments is not, Wasica Fin. GmbH v. Cont’l Auto. Sys., Inc., 853 F.3d 1272, 1286 (Fed. Cir. 2017). Accordingly, Petitioner’s change of arguments here is inappropriate. Moreover, even if we were to consider Petitioner’s inappropriate new argument, we would conclude that Petitioner does not support the argument with sufficient evidence. “Whether [an obviousness ground] is based on combining disclosures from multiple references, combining multiple embodiments from a single reference, or selecting from large lists of elements in a single reference, there must be a motivation to make the combination and a reasonable expectation that such a combination would be successful, otherwise a skilled artisan would not arrive at the claimed combination.” In re Stepan, 868 F.3d 1342, 1346 n.1 (Fed. Cir. 2017). Petitioner’s new argument relies on a person of ordinary skill in the art modifying the Figure 5 embodiment of Mishra to connect the field plate to the source rather than the gate. Reply 21–24. Petitioner does not, however, show that a person of ordinary skill in the art would have had a motivation to make this modification or a reasonable expectation that this combination would be successful. Id. Petitioner argues instead that “[n]o ‘reason’ is needed.” Id. at 24. Thus, Petitioner does not show by a preponderance of the evidence that claim 1 would have been obvious over the combination of Mishra and Ren.” slip op. at 19

    “According to the ’713 patent, “[p]urge tower 24 itself may be . . . recycled or otherwise discarded as desired.” Ex. 1001, 8:27–28. This description provides some support for Patent Owner’s view, because a purge tower too intimately integrated with the part would be difficult or impossible to recycle or discard. This is further supported by the ’713 patent’s statement that “purge tower 24 may be printed at any suitable location on build substrate 44 (i.e., at any location in the x-y build plane not occupied by 3D part 20 or support structure 22).” Id. at 8:30–34. It also is supported by Dr. Hickner’s testimony that the ’713 patent “clearly shows . . . the 24 purge tower separated from the part” and that “the purge tower is a separate physical object.” Ex. 2016, 28:8–10, 64:1–9. On the other hand, there is evidence supporting Petitioner’s view that, as long as the purge tower is generally separate from the part and the support structure, it may still make contact with those portions of the print. As noted above, “purge tower 24 may be printed at any suitable location on build substrate 44 (i.e., at any location in the x-y build plane not occupied by 3D part 20 or support structure 22).” Ex. 1001, 8:30–34. This language does not exclude locations adjacent to or in contact with the part or the support structure. Thus, determine that a “purge tower,” as that term is used in the context of the ’713 patent, may not be an integrated portion of a printed part or support structure but need not be free of all contact with the printed part or support structure.” slip op. at 9

    “There is evidence of record to support both Petitioner’s view and Patent Owner’s view. On the record developed at trial, however, we cannot say that the preponderance of the evidence favors Petitioner, who bears the burden of proof. See 35 U.S.C. § 316(e). Accordingly, Petitioner has not shown by a preponderance of the evidence that KISSlicer teaches printing a layer of a purge tower each time the printer switches one extruder to the operating mode. Because proving the obviousness of claims 1 and 16 requires such a showing, Petitioner has not shown by a preponderance of the evidence that claims 1 and 16 would have been obvious over the combination of Priedeman and KISSlicer. 5. Analysis of Remaining Claims Claims 2, 6, 7, 9, and 17 all depend, directly or indirectly, from claim 1 or claim 16. Accordingly, they all include the limitations of either claim 1 or claim 16. Because, as discussed above, Petitioner has not shown that the combination of Priedeman and KISSlicer teaches or suggests all the limitations of claims 1 and 16, Petitioner also has not proven by a preponderance of the evidence that claims 2, 6, 7, 9, and 17 would have been obvious over that combination of references.” slip op. at 21

    “offers nothing to suggest that its card information ‘tells you’ where to store the fingerprint data.” ASSA ABLOY AB, 2025 WL 3134960 at *3. Reversing our determinations as to Hsu, the Court found that the testimony of Petitioner’s declarant, Mr. Lipoff, “merely confirms the associative link between the card information and the biometric data. Still missing is any non-conclusory testimony that Hsu’s card information determines the memory location of the biometric data.” Id. at 8. Therefore, on remand, a central question is whether Petitioner has shown sufficiently that Tsukamura cures this deficiency. Petitioner has not done so. In the Petition, Petitioner relies on Tsukamura for teaching a specific location for storing fingerprint data. See Pet. 75 (stating that “Tsukamura’s index number specifies the physical memory location in the memory”). Petitioner argues that “[t]hus, Tsukamura discloses defining, dependent upon the “index number N index,” a memory location for storing a biometric signature (e.g., a fingerprint template), i.e., ‘a memory location is specified by the card information.’” Id. at 75–76 (citing Ex. 1006 ¶ 215). In support, Petitioner’s declarant, Mr. Lipoff, testifies that “[i]f the Tsukamura implementation were used for Sanford-Hsu database, each user/account number would specify a different entry (index number) in the database.” Ex. 1006 ¶ 394. Tsukamura’s index number N index does not teach or suggest much more than Hsu’s using “an account number or employee number, to access a stored there during an enrollment procedure.” Compare Ex. 1004, code (57), with Ex. 1005, 4:7–11. That is, both references arguably teach defining, i.e., setting or establishing, a certain location in a database for biometric data. For example, as described above, Tsukamura’s fingerprint template Temp is stored in flash ROM 35 at a defined index number N index in the database. Id. 4:7–11, 50–54. However, neither Petitioner, nor Mr. Lipoff, persuasively explain how or why Tsukamura’s fingerprint template Temp, stored at index number N index, is commensurate with “means for defining, dependent upon the received card information, a memory location in a local memory external to the card” as recited in claim limitation 13[C].

That is, both references arguably teach defining, i.e., setting or establishing, a certain location in a database for biometric data. For example, as described above, Tsukamura’s fingerprint template Temp is Id. 4:7–11, 50–54. However, neither Petitioner, nor Mr. Lipoff, persuasively explain how or why Tsukamura’s fingerprint template Temp is set or established “at a memory location defined by the provided card information” as recited in claim limitation 3(da). Taking a close look at Petitioner’s testimonial evidence as to claim 3, we first note Mr. Lipoff testifies that Tsukamura’s index number specifies the physical memory location in the memory. Thus, Tsukamura discloses defining, dependent upon the “index number N index,” a memory location for storing a biometric signature (e.g., a fingerprint template), i.e., the memory location is specified by the index number, under the Second Construction. In my opinion, if the Tsukamura implementation were used for Sanford-Hsu database, each user/account number would specify a different entry (index number) in the database. Ex. 1006 ¶ 394. This is consistent with our understanding of Tsukamura, and we can agree that Tsukamura teaches defining—that is, setting or establishing—a location for storing the biometric signature at “index number N index.” See Ex. 1005, 4:7–11. But, concomitant with the Federal Circuit’s point, such an associative link does not sufficiently explain how one of ordinary skill in the art would have understood Tsukamura’s IC card information to define “as in ‘set’ or ‘establish[]’” a memory location, as our claim construction requires. See Section II.C.3.” slip op. at 22
