      “b) Walker Priority Date Under Dynamic Drinkware, the Petitioner is required to show that “the provisional application provides support for the claims of the patent or published application.” In re Riggs, 131 F.4th 1377, 1384 (Fed. Cir. 2025). Thus, Petitioner must show that (1) at least one claim of Walker is supported by its provisional (U.S. Provisional Application No. 60/378,289 (the “’289PROV”) and (2) the specific subject matter relied upon as prior art is supported by the ’289PROV. Id. Petitioner does provide a detailed explanation about how the ’289PROV supports claim 1 of Walker. See Reply 5–10. However, as Patent Owner argues, Petitioner fails to show that the ’298PROV provides support for the specific subject matter relied on in Walker. See Sur-Reply 3–9. Petitioner only explains how the ’298PROV discloses “predetermined criteria” but does not provide any other explanation for how the other subject matter relied on in Walker is supported by the ’298PROV. Thus, we find that Petitioner has failed to show that Walker is entitled a priority date before May 1, 2003. See Riggs, 131 F.3d at 1384 (noting while “a prior art patent or published application cannot be accorded the benefit of its provisional application’s filing date absent a showing that the provisional application provides support for the claims of the patent or published application,” the challenger must also show that “the specific portions of the patent specification identified and relied on” to demonstrate purported invalidity have written description support).” slip op. at 25

      “evidence that Kelly teaches limitations 1[d.i] and 1[d.ii]. As Patent Owner persuasively argues, “the recorded information regarding particular game play events” of limitations 1[d.i] and 1[d.ii] refers to “memory to . . . record game play information regarding particular game play events” in limitation 1[b.ii], but Petitioner does not map “the game play events” identified in limitation 1[b.ii] to limitations 1[d.i] and 1[d.ii]. In its Reply, Petitioner does not dispute Patent Owner’s assertion, but largely reiterates its arguments from the Petition. However, none of these arguments or evidence demonstrates that the “game play events” in limitations 1[d.i] and 1[d.ii] are same the “game play events” that are allegedly stored in limitation 1[b.ii]. Even if we accept Petitioner’s contention that it was not identifying button presses or the “game identifier,” but rather includes “game states and game events in the game process,” Petitioner provides no evidence or even arguments that what it has identified here relates to what it has identified for limitations 1[d.i] and 1[d.ii]. See Pet. 29–33 (citing Ex. 1005, 25:23–24, 26:59–27:1, 32:27–33, 37:1–10, 38:66–39:7 40:33–45, 56:49–51, 57:27–33). For these reasons, Petitioner has failed to show by a preponderance of the evidence that Kelly teaches or suggests limitations 1[d.i] and 1[d.ii]. Accordingly, we find that Petitioner has failed to show that claim 1 would have been obvious over Kelly. 2. Claims 3–9, 13, 17, 18, 23, 25, 26, 28, and 29 Claims 3–9, 13, 17, 18, 23, 25, 26, 28, and 29 all depend (either directly or indirectly) from claim 1. See PO Resp. 16 (explaining that the arguments for independent claim 1 also apply to the dependent claims inherent the deficiencies asserted with respect to the independent claims). We find Patent Owner’s arguments availing, as explained above. Accordingly, we find that Petitioner has failed to show by a preponderance of the evidence that claims 3–9, 13, 17, 18, 23, 25, 26, 28, and 29 would have been obvious over Kelly.” slip op. at 44

      “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 addition to Eckert disclosing a single transport channel E-DCH, Petitioner argues that Eckert discloses using a “finite quantum of physical resources” where “[t]he ’138 patent disclosure parallels Eckert, with both the E-DCH and CCTrCH transport channels relating to a UMTS uplink, employing spreading codes in code division multiple access (CDMA), and Reply 6 (citing Ex. 1005, ¶¶ 3, 8, 15, 23; Ex. 1071 ¶¶ 17–20; Ex. 1011 ¶¶ 6, 51).

      “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

      “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].

      “introduced during said workflow by collapsing target:differentiator tag combinations observed more than once into a single count.” Ex. 1001, 131:46–48 (emphasis added). The “determining step” of claim 2 recites “determining a consensus base call for the target nucleic acid molecule sequences,” but performs “collapsing all sequence reads comprising a same differentiator tag into a single read,” before the “determining step.” Id. at 131:49–53. Patent Owner proposes an interpretation of these “collapsing” and “determining” steps recited in claims 1 and 2 and asserts that they should be construed as distinct steps performed in a particular order in which the “collapsing step” is performed before the “determining step.” PO Resp. 42–45. We agree. First, Patent Owner asserts a person of ordinary skill in the art would have understood that the “collapsing step” of claim 1 is distinct from, and must occur before, the “determining step” of claim 2 based on the plain language of claims 1 and 2. PO Resp. 42–43. Patent Owner argues that the “collapsing step” and the “determining step” are distinct steps because claims 1 and 2 use different terms to describe these distinct steps that are performed sequentially according to the claim language. Id. (citing Ex. 1001, 131:47–54; Ex. 2023 ¶ 133; Ex. 2024, 57:11–58:22). More specifically, Patent Owner explains that claim 1 recites a “collapsing step,” followed by claim 2, which depends from claim 1 and refers to “collapsing” before “determining a consensus base call” such that “claim 2 describes determining a consensus base call from collapsed reads, not performing ‘collapsing’ by determining a consensus base call.” Id. at 42 (citing Ex. 1001, 131:47–54). collapsing corrects for skewing, an issue related to over- or under-amplification, which is a separate and distinct problem from the sequence errors that a consensus base call is designed to address.” Id. at 43 (citing Ex. 1001, 27:47–50, 32:29–34). Patent Owner contends further that “‘[c]ollapsing’ is a different step, performed separately from determining any consensus base call, to provide even greater accuracy when subsequently determining a consensus base call” such that “if one were to collapse by determining the consensus base call, errors from amplification bias could still be represented in the consensus base call generated.” Id. at 43–44 (emphasis omitted, citing Ex. 2023 ¶¶ 134–37). Second, Patent Owner argues a person of ordinary skill in the art would have understood that the “collapsing step” of claim 1 is distinct from the “determining step” based on the specification of the ’730 patent. PO Resp. 43–45. For example, Patent Owner explains that the specification states that “[f]or any target:differentiator tag combination observed more than once, all such reads are ‘collapsed’ into a single read before consensus basecalls are determined. This will cancel the effect of bias on consensus basecall accuracy.” Id. at 43 (emphasis omitted) (quoting Ex. 1001, 72:63– 73:5) (citing Ex. 2023 ¶¶ 133, 138–142).” slip op. at 11

      “We have considered both parties’ arguments and evidence and agree with Patent Owner’s position. As discussed above, we agree with Patent Owner that the “collapsing step” recited in claim 1 and the “determining step” recited in claim 2 are two different steps required by the challenged claims such that “collapsing” does not mean determining a consensus base call or sequence, and must occur before any determining step. As a result, we determine Chee’s step of determining a consensus sequence does not disclose the “collapsing step” recited in claim 1 that requires collapsing “target:differentiator tag combinations.” We are also unpersuaded by Petitioner’s reliance on Chee’s process of correcting for amplification bias as disclosing the claimed collapsing step. As recognized by Patent Owner, the claim language of the “collapsing step” requires “collapsing target:differentiator tag combinations,” rather than collapsing only differentiator tags. In view of this requirement, Chee does not disclose the “collapsing step” because Chee teaches quantifying the starting nucleic acid molecules using their unique identifiers, rather than target:differentiator tag combinations. As Petitioner admits, “Chee’s technique for correcting amplification bias corrects quantitative errors without correcting sequencing errors” (Reply 15), whereas claim 1’s “collapsing step” corrects both quantitative errors and sequencing errors by using target:differentiator tag combinations.

We further agree that cis-reactive cells should be construed to mean “an association of at least two interactor moieties, joined by an associated oligonucleotide.” (PO Resp. 9 (quoting Ex. 1001, 9:35-37)).

See Tr. 28:15–18. We do not read the ’772 Publication as calling for a search for a more efficient variant to improve efficient gene transfer in liver. We credit Dr. Samulski’s testimony that supports this view of the teachings of the ’772 Publication. Dr. Samulski testifies: Additionally, when the inventors compared AAV8’s expression in the liver against new serotypes AAVrh2, AAVrh10, AAVrh13, and AAVrh21, they found that AAV8 remained superior: EX1007, ¶ 253. Notably, AAV8 was shown to have over fifty percent (50%) greater expression in liver than AAVrh10. As I discuss more below, a skilled artisan in 2005 would not have expected a single amino acid substitution to significantly alter tropism in order to target to a different tissue. Thus, in my opinion, in 2005, a skilled artisan with the goal of targeting the liver would have selected the best known vector for delivery to liver at that time—AAV8. Ex. 2027 ¶ 42. We also agree with Dr. Samulski’s opinion that a POSA would have selected the best vector for liver, AAV8, instead of modifying another vector to increase tropism to liver. Dr. Samulski testifies: In my opinion, a skilled artisan in 2005 would not have looked solely to modify a vector to try to improve tropism to a particular tissue. As discussed throughout this declaration, changing tropism is difficult to predict, and a skilled artisan would not have had a reasonable expectation that changes could be made to improve or alter tropism. A skilled artisan would also have been concerned that changes, even small ones, could negatively impact other properties of the capsid protein.

Importantly, AAV2/8 provides a substantial advantage over the other serotypes in terms of efficiency of gene transfer to liver that until now has been relatively disappointing in terms of the numbers of hapatocytes stably transduced. AAV2/8 consistently achieved a 10 to 100-fold improvement in gene transfer efficiency as compared to the other vectors. The basis for the improved efficiency of AAV2/8 is unclear, although it presumably is due to uptake via a different receptor that is more active on the basolateral surface of hepatocytes. This improved efficiency will be quite useful in the development of liver-directed gene transfer where the number of transduced cells is critical, such as in urea cycle disorders and familial hypercholesterolemia. Id. (citations omitted) (emphasis added). According to the import of the complete recitation of paragraph 250 of the ’772 Publication set forth above that Petitioner relies upon for the motivation to improve efficient gene transfer in liver, AAV8 already fulfills this need. See Tr. 28:15–18. We do not read the ’772 Publication as calling for a search for a more efficient variant to improve efficient gene transfer in liver. We credit Dr. Samulski’s testimony that supports this view of the teachings of the ’772 Publication. Dr. Samulski testifies: Additionally, when the inventors compared AAV8’s expression in the liver against new serotypes AAVrh2, AAVrh10, AAVrh13, and AAVrh21, they found that AAV8 remained superior:” slip op. at 28
