“B. Scope on Remand On remand, we are bound by the terms of the Federal Circuit’s mandate. Intell. Pixels Ltd. v. Sony Interactive Ent. LLC, 181 F.4th 1216, 1220 (Fed. Cir. 2026) (“An administrative agency is bound by the mandate of a reviewing court much as a lower court is bound by the mandate of a higher court.”). According to the Federal Circuit, on appeal, Patent Owner “UW argues that ‘Travers ’075 does not enable the sequencing of an RCR concatemer using PacBio’s SMRT sequencing,’ and therefore because paragraph 122 is not enabled, it cannot be relied on for disclosing amplification followed by sequencing.” Paper 50, 14. Because “[t]he Board did not reach this issue,” the Federal Circuit “remand[ed] the case for consideration of this issue by the Board in the first instance.” Id. Thus, consistent with the court’s mandate, we must decide “whether Travers ’075 enabled RCR amplification followed by SMRT sequencing.” Id. at 8.” slip op. at 4

Cir. 2012) (extending the presumption to prior art printed publications). A patent owner, however, may present persuasive evidence that the relevant disclosures of a prior art are not enabled and therefore are not pertinent prior art. Amgen, 314 F.3d at 1355; In re Antor Media, 689 F.3d at 1289 (discussing the applicant’s burden to submit rebuttal evidence of nonenablement during prosecution); Apple Inc. v.

Corp. v. Gen. Elec. Co., 993 F.3d 1374, 1376–77 (Fed. Cir. 2021). But, “if an obviousness case is based on a non-self-enabled reference, and no other prior art reference or evidence would have enabled a skilled artisan to make the claimed invention, then the invention cannot be said to have been obvious.” Id. at 1377.” slip op. at 15
- Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached
“The Federal Circuit stated that “the elements of the challenged claim are expressly taught by Travers ’075. Travers ’075 discloses performing RCR amplification followed by SMRT sequencing in a single embodiment.” Paper 50, 14. As a result, “no finding regarding a motivation to combine to arrive at those claimed elements is required.” Id. at 9. In addition, it was error to require Petitioner to show that a skilled artisan “would have had a reasonable expectation of success in performing RCR replication of SMRTbell templates followed by SMRT sequencing.” Id. at 13. “Unless remanded by [an appellate] court, all issues within the scope of the appealed judgment are deemed incorporated within the mandate and thus are precluded from further adjudication.” Engel Indus., Inc. v. Lockformer Co., 166 F.3d 1379, 1383 (Fed. Cir. 1999).

Citing the Larrea Declaration, Petitioner contends that loading of multiple templates “is easily mitigated.” Id. at 18 (citing Ex. 1033 ¶ 19; Ex. 1035, 39). We are not persuaded by this argument either. Dr. Larrea testifies that one of the two methods to “easily mitigate[]” loading multiple templates into a single ZMW is “bioinformatically trimming the read to only the high-quality region (HQR).” Ex. 1033 ¶ 19. Dr. Larrea, however, provides no support for this testimony. In fact, he does not even explain what a “high-quality region (HQR)” is. We, thus, accord little weight to this testimony.

“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. See Ex. 1001, 131:47–49 target:differentiator tag combinations).” slip op. at 41

“Given this claim interpretation requiring collapsing target:differentiator tag combinations, it is undisputed that McCloskey, who uses unique barcodes alone, does not teach this limitation. Petitioner does not rely on Bignell as teaching this collapsing step. Accordingly, we conclude Petitioner has not shown that the combination of Bignell and McCloskey teaches the “collapsing step” recited in claim 1. Because claims 4 through 6 depend from claim 1, they also require the “collapsing step” of claim 1 that is not taught by the combination of Bignell and McCloskey.” slip op. at 54

“As an initial matter, we acknowledge that the definition “to process so as to add or increase the proportion of a desirable ingredient” has two possible interpretations. In the first interpretation, “add or increase” shares the same object “the proportion of a desirable ingredient.” When the proportion of one ingredient goes higher, the proportion of at least another ingredient would necessarily go lower. Thus, the enrichment process under this interpretation results in a higher proportion of the desirable ingredient relative to other ingredients. Patent Owner adopts this interpretation. See PO Resp. 17 (“In the context of preparing a sequencing library, [Patent Owner] Tecan proposes that a nucleic acid sequence of interest is ‘enriched’ when the proportion of nucleic acid fragments containing the sequence of interest is increased relative to other nucleic acid fragments in the sample.”). According to Patent Owner, “amplifying the one or more oligonucleotide extension products . . . thereby enriching the nucleic acid sequence of interest, by generating amplified products comprising the enriched nucleic acid sequence of interest” in step (c) means “increas[ing] the proportion of the nucleic acid sequence of interest relative to the nucleic acid fragments in the solution not containing the sequence of interest by amplifying the oligonucleotide extension product and its complement.” Id. at 19–20. Under the second interpretation, the object for “add” is “a desirable ingredient,” whereas the object for “increase” is “the proportion of a desirable ingredient.” This interpretation is broader than the first one in that the result of the enrichment process not only encompasses a higher proportion of the desirable ingredient relative to other ingredients, but also more desirable ingredient in raw number.” slip op. at 11

“Because the parties have placed the limitation “selecting all cis- reactive cells exhibiting the detectable trace” into controversy, we construe the term below, but only to the extent necessary to resolve the controversy.

For the reasons discussed below, we agree with Patent Owner that the plain and ordinary meaning of this phrase, in light of the language of the claims, the Specification, and the prosecution history of record, requires “selecting all of the [molecular complexes or structures] meeting the defined criteria for [cis-reactive cells (CRCs)] and exhibiting the detectable trace.” Sur-reply 8 (citing Ex. 2008 ¶¶ 94, 98–119). 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)).

Thus, the selected molecular complex or structure does not comprise two interactors (i.e., two molecules of interest coupled to NAMs).

Here, the claimed invention is a method for reducing template cross-over error. Thus, we must determine whether, in December 2010, an ordinarily skilled artisan would have reasonably expected that the combination of Parameswaran and Gloor would reduce template cross-over error. slip op. at 26

“Thus, on this record, we are persuaded by Patent Owner’s argument that Parameswaran’s “unexpected perfect pairings of unmatched forward and reverse barcodes” are not cross-over error. PO Resp. 31 (citing Ex. 2001 ¶¶ 116–123). In addition, as Petitioner acknowledges, Parameswaran merely “distinguished,” but did not “discard” sequences with mismatches. Pet. 34. Parameswaran states that “[t]he low false-discovery rate for perfect matches strengthens the argument that any sequence with both 5’ and 3’ barcode motifs will be placed with reasonable accuracy into the correct bin.” Ex. 1004, 8. But, because Parameswaran achieved a “remarkably low misassignment rate,” it did not discard, but included any sequence with a matched barcode. Id. Indeed, Parameswaran explains that “[f]or our purposes, all sequences with a match to one of the two expected sequence motifs were considered as true members of the corresponding dataset.” Id. In its Reply, Petitioner emphasizes Parameswaran’s language “[f]or our purposes.” Reply 14 (citing Ex. 1004, 8). According to Petitioner, “[a] POSA would have understood from Parameswaran that chimeric sequences could be kept or discarded, depending on the sequencing ‘purpose.’” Id. (citing Ex. 1054 ¶¶ 79–82). Petitioner is asking us to deem unpatentable a claim based on its reading of “for our purposes,” a broad, undefined statement, to mean something specific—a suggestion to discard perfect unexpected pairings, which Parameswaran explicitly did not do. See Ex. 1004, 8. Petitioner has not presented sufficient evidence and persuasive argument for us to do so.” slip op. at 24

“For a claim to a biological material, the enablement requirement of § 112, first paragraph, does not require such assured access to a microorganism deposit as of the filing date; what is required is assurance of access (to the microorganism culture by the public upon issuance of a patent on the application) prior to or during the pendency of the application, so that, upon issuance of a U.

“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: 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. Therefore, rather than seek to modify a vector, a skilled artisan” slip op. at 29

“The ’772 Publication, however, does not indicate as Petitioner asserts that a new variant is necessary to improve the efficiency of gene transfer to liver; the ’772 Publication indicates that AAV8 fulfills that need. See Ex. 1007 ¶ 250. In the paragraph that Petitioner relies upon for the alleged need to improve the efficiency of gene transfer to the liver, the ’772 Publication states in full: The tropism of each new vector is favorable for in vivo applications. AAV2/7 vectors appear to transduce skeletal muscle as efficiently as AAV2/1, which is the serotype that confers the highest level of transduction in skeletal muscle of the primate AAVs tested to date. 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.

Katzir also discloses various LED array layouts that a POSITA would have a looked to when designing an LED tube lighting like that disclosed in Kit. A POSITA would have had strong motivation to look to Katzir to design an LED array to be retrofit in a fluorescent tube form factor. Ex. 1003 ¶ 102 (internal citations omitted). As discussed above, however, the cited passages of Kit describe a light with LEDs that produces a single, consistent temperature of warm white, commercial white, or cool white.

Paragraph 490 of Exhibit 1003 relates to Ducharme, not Hasnain, and thus, does not support Petitioner’s argument. Although paragraphs 41 to 49 of Exhibit 1049 span more than seven pages, other than the single citation in the Reply, Petitioner does not discuss any of the testimony presented therein. We, thus, do not consider this portion of the Holmes Supplemental Declaration. See 37 C.F.R. §§ 42.6(a)(3). Furthermore, we would not be persuaded by Mr. Holmes’ testimony even if we considered it. For example, Mr. Holmes testifies that Hasnain’s heat-dissipating structure “a variety of heat dissipating techniques are disclosed by Hasnain, any one of which could readily be used in a T12 form factor LED light, as expressly recognized by Hasnain.” Ex. 1049 ¶ 46. We disagree with Mr. Holmes that Hasnain teaches enclosing its heat-dissipating structure in a fluorescent light tube. Hasnain teaches “a replacement LED light source for fluorescent tube 22 [that] plug[s] into the same connectors and operate[s] from the voltage patterns generated by the ballasts.” Ex. 1008, 3:23–26. Hasnain also teaches that “the replacement LED light source has a plurality of LEDs mounted on a heat-dissipating substrate that has a width that is less than or equal to the diameter of the fluorescent tube that the light source is designed to replace.” Id. at 5:52–56. Thus, Hasnain teaches that its LED light fits into, and connects with, an existing structure that previously held a fluorescent light tube. Id. at 2:50–56, 3:23–26, 4:58–64, 5:52–56, Figs. 1A, 4.
