    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot shown unpatentableNot shown unpatentable

      “We agree with Patent Owner that Petitioner’s contentions in this ground do not cure the issues for limitations 1D and 1E. Petitioner’s contentions in this ground involve combining Khan and Ali’s teachings of identifying a horizon line and lane lines with Choe. For example, Petitioner argues that “[u]sing predictive models for Choe’s lane and horizon prediction would have combined known elements according to known methods to yield predictable results” and that “[i]mplementing these known mathematical models in Choe’s calibration system, according to their known functions, would have yielded predictable results.” Pet. 39. Petitioner further argues that “[u]sing predictive models for Choe’s lane and horizon prediction would have used a known technique (predictive models) to improve similar devices in the same way” and that “[u]sing predictive models for Choe’s lane and horizon prediction would have also applied a known technique (predictive models) to a known device (a manual annotator device) ready for improvement.” Pet. 40. Petitioner’s proposed combination, therefore, still relies on Choe’s teachings of transmitting an overlaid image to an annotator device. We note that Petitioner asserts that, “[o]nce Khan in view of Ali identifies the horizon and lane lines, it overlays the horizon line and/or lane lines on the video, as shown in the screenshots below.” Pet. 41–42. Although Petitioner mentions Khan and Ali’s teachings with respect to video here, Petitioner does not adequately explain how the teaching of an overlaid video would be combined with Choe’s single image annotator teachings. As discussed above, Choe discloses transmitting a single overlaid image to the annotator” slip op. at 23

      “Thus, Petitioner has not provided sufficient evidence and argument to explain how the additional teachings of Khan and Ali teach limitations 1D and 1E in combination with Choe. Petitioner, therefore, has not demonstrated unpatentability of claims 1–5 by a preponderance of the evidence. F. Obviousness over Choe and Workman (Claims 1–4) Petitioner asserts that claims 1–4 would have been obvious over the combined teachings of Choe and Workman. Pet. 47–52; Pet. Reply 26–30. Petitioner asserts that, “if [Patent Owner] alleges that Choe does not explicitly disclose which predictive models it uses or whether it uses predictive models to identify the horizon line, a [person of ordinary skill in the art] would have searched for references that use predictive models and how such models were used,” which “would have led to Workman, which discloses predictive models to identify the horizon line.” Pet. 47. According to Petitioner, “[u]sing Workman’s predictive model to identify the horizon line would also have merely been combining known elements ([convolutional neural networks (CNNs)] and annotation for camera calibration) according to known methods to yield predictable results and used known techniques (CNNs) to improve similar devices in the same way.” Pet. 48–49. Thus, Petitioner relies on Workman to teach a predictive model to identify a horizon line. See Pet. 47–49. Choe with respect to limitations 1D and 1E. Indeed, Workman involves horizon line estimation in single images. See Ex. 1011, 10 (§ 5) (“We introduced Horizon Lines in the Wild (HLW), a new dataset for single image horizon line estimation, to address the limitations of existing horizon line detection datasets.”). Petitioner, therefore, has not demonstrated unpatentability of claims 1–4 by a preponderance of the evidence.” slip op. at 24

      “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

      “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. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). 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)). Accordingly, we determine that, properly construed, the claims require that what is “selected” at step 1(d) — what is differentiated or set apart from other molecular complexes or structures in the reaction mixture at the conclusion of step 1(d) — to be “an association of at least two interactor moieties joined by an associated oligonucleotide” that exhibits the detectable trace.” slip op. at 16

      “We agree that Petitioner has not shown that the combination of Kanan and Neri teaches “selecting all cis-reactive cells exhibiting the detectable trace,” as we have construed that phrase above. In particular, we determine that, properly construed, the limitation requires the selection of “all associations of at least two interactor moieties joined by an associated oligonucleotide and exhibiting the detectable trace.” Instead, as described in Kanan, what is “selected” is the molecules of interest joined by bond formation, with only one of the molecules of interest coupled to a nucleic acid moiety. Thus, the selected molecular complex or structure does not comprise two interactors (i.e., two molecules of interest coupled to NAMs). Moreover, to the extent there are two interactors, they are joined by the bond between the molecules of interest rather than an associated oligonucleotide.” slip op. at 35

      “specification to interpret the meaning of a claim and importing limitations from the specification into the claim can be a difficult one to apply in practice.” Phillips, 415 F.3d at 1323. “[T]he line between construing terms and importing limitations”, however, “can be discerned with reasonable certainty and predictability if [our] focus remains on understanding how a person of ordinary skill in the art would understand the claim terms.” Id. Ultimately, we construe claim terms to “capture the scope of the actual invention more accurately than either strictly limiting the scope of the claims to the embodiments disclosed in the specification or divorcing the claim language from the specification.” Id. at 1324. Here, we are tasked with resolving the dispute between the parties as to the scope of the source of the claimed cross-over error. See Sur-reply 2. Although claim 1 does not explicitly recite cross-over error is created during cluster amplification, the specification shows otherwise. It repeatedly, consistently, and exclusively describes cross-over errors as arising from the formation of chimeric molecules during the amplification step of the sequencing workflow. See Ex. 1001, Fig. 1, Fig. 2, 4:29–52 (describing “improper molecular overlap via formation of a heteroduplex between patient A’s nucleic acid template and patient B’s nucleic acid template” “[w]hen the amplification process begins”), 5:29–58 (the same), 6:25–44 (the same), 6:64–7:23 (the same).” slip op. at 15

      “The reasonable expectation of success requirement refers to the likelihood of success in combining references to meet the limitations of the claimed invention.” Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 9 Because, as explained below, we find Petitioner has not met its burden to show reasonable expectation of success, we do not need to address whether Petitioner has shown sufficient reason to combine the asserted references. 821 F.3d 1359, 1367 (Fed.

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

      “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.

      “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.

      “As to the first issue, we agree with Patent Owner that defining the level of skill in view of the solution described in the patent risks improper hindsight. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) 18 (“[T]he level of skill in the art is a . . . lens through which . . . the Board views the prior art and the claimed invention,” which “prevents . . . factfinders from using their own insight or . . . hindsight[] to gauge obviousness.”).

      “person of ordinary skill in the art would employ” in an obviousness analysis, we give some weight to Dr. Guengerich’s testimony. KSR, 550 U.S. at 418; Plantronics, Inc. v. Aliph, Inc., 724 F.3d 1343, 1354 (Fed.

Nevertheless, even if we were to agree that an ordinarily skilled artisan would have seen the 1,5-shift in NRPE in Mata’s A2E biosynthetic pathway as a particularly desirable location for intervention, we are not persuaded that such a person would have been motivated to substitute C20 deuterated vitamin A for the vitamin A in Ortho Pharma’s composition and method, because Petitioner has not shown, by a preponderance of evidence, that such an artisan would have reasonably expected the substitution to retard the accumulation of A2E or to treat macular degeneration.” slip op. at 42

      “c. Analysis We agree with Patent Owner. On this record, we find that Loderer does not teach or suggest the recited “target machine condition code.” Loderer says that “[t]he object of [its] invention is . . . to specify a method for simulating a condition code when porting hardware-specific program code from a source hardware to a target hardware that is not providing for condition code.” Ex. 1005, col. 1, para. 5 (emphasis added). Loderer’s claims are directed to “[a] method for simulating a condition code (CC), used for the execution of hardware-specific program code (PCU) for a source hardware (M1), in the program code (PCZ), obtained following transformation, for a differing target hardware (M2) with a machine architecture which operates without a condition code (CC).” Id., claim 1. In other words, Loderer’s target machine does not support condition codes, let alone a “target machine condition code.” Accordingly, Loderer does not teach or suggest a “target machine condition code.”” slip op. at 23

    • BurdenNot shown unpatentable

      “Having considered these arguments on the full trial record, we find Patent Owner has the better position because Petitioner’s showing that element 1(b) is taught by Schmitt is unpersuasive. We begin with Patent Owner’s argument concerning the distinction between the cfDNA molecules and the duplex tag comprising the molecular barcode found in the text of claim 1. Element 1(a) recites “a population of cell-free deoxyribonucleic acid (cfDNA) molecules.” Ex. 1001, 61:7–9. Element 1(b) recites “tagging a plurality of the cfDNA molecules in the population” of element 1(a) “with duplex tags comprising molecular barcodes to produce tagged parent polynucleotides . . . wherein the duplex tags are attached to both ends of a added). We agree with Patent Owner and credit the testimony of its declarant that this claim language distinguishes the duplex tags from the ends of the cfDNA molecule to which they are attached. Resp. 8; Ex. 2015 ¶¶ 38–39, 60, 61. That is, the duplex tag is not part of the cfDNA molecule itself, but rather is “attached to both the ends” of that molecule by “tagging” it as recited in element 1(b). We also agree with Patent Owner that given this distinction, claim 1 does not encompass Schmitt’s hybrid embodiment. Resp. 18–20. As Petitioner notes, “[i]n Schmitt’s hybrid-tag embodiment, the strands are grouped based on the combination of the short n-mer barcode and the end of the target DNA.” Pet. 11; see Resp. 17 (“[T]he combination of the endogenous shear sequence and exogenous 3-mer sequence together provide the SMI used for grouping and matching in Schmitt’s DCS process.”). Petitioner and its declarant illustrate the grouping in Schmitt’s hybrid embodiment with the following diagram. Pet. 12; Ex. 1002 ¶¶ 96–98. Petitioner’s diagram shows the PCR products produced from sequencing a “Target DNA” molecule that has been tagged with 3-mers X and Y according to Schmitt’s hybrid embodiment. See Ex. 1002 ¶ 98 (describing diagram). A portion of the endogenous sequence of the DNA molecule labeled L and R is used in combination with the 3-mer sequence to group the resulting strands into two families labeled the “X+L→R+Y Family” and the “R+Y→X+L Family.” Ex. 1002 ¶ 98; Ex. 2015 ¶ 62 (explaining that Petitioner’s diagram shows that “the relied upon hybrid SMI sequences of Schmitt include sequence from the sample DNA molecule not contained in the adapter or the duplex tags”). SMIs, differently label the strands and therefore are the recited “duplex tags.” See Pet. 27–28 (“duplex tags comprise both the fragment DNA end sequences and a shorter n-mer tag”) (emphasis added) (internal quotations omitted). However, we credit Dr. Quackenbush’s testimony that end sequences L and R are not “attached to both ends” of the cfDNA molecule by “tagging” it as recited in element 1(b). See Ex. 2015 ¶ 59–62 (explaining that Schmitt’s hybrid SMI sequences include a portion of the sample DNA molecule, which is “not contained in adapter molecules or duplex tags that are attached to the DNA molecules”). Rather, end sequences L and R are the pre-existing, endogenous ends of that molecule. Id. Thus, Petitioner’s theory of unpatentability does not account for the distinction the claim language draws between the cfDNA molecule and the duplex tags.

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot shown unpatentableNot shown unpatentable

      “That is, although Meyer teaches that its particular protocol results in 40–60% tagging efficiency, Petitioner has not sufficiently explained why a person of ordinary skill in the art would have expected Meyer’s tagging efficiency to apply to Schmitt’s DCS method when used with Narayan’s sequencing of cfDNA. For example, the Petition does not address the differences between Meyer’s adapters and Schmitt’s adapters and how those differences affect the tagging efficiency. Meyer’s barcodes comprise “single self-hybridized palindromic oligonucleotides, carrying an Srf I restriction site in the middle (GCCCGGGC), a sequence tag at the 3’ end and the reverse complementary tag sequence at the 5’ end.” Ex. 1005, Fig. 1. Schmitt, on the other hand, teaches a “hybrid method” of tagging that uses a combination of the sheared ends of the DNA fragments and a “shorter n-mer tag (such as 1 or 2 or 3 or 4 or more degenerate or semi degenerate bases) in the adaptor.” Ex. 1083 ¶ 30. sticky-end adapter-DNA litigation to be even more efficient than Meyer’s blunt-end adapter-DNA ligation” is also unpersuasive. See Pet. 60–61. The KAPA data sheet discloses sticky-end adapter DNA ligation, but KAPA teaches that only 0.5 to 15% tagging efficiency is expected when the starting sample is 100 pg–100 ng of “high quality DNA.” Ex. 1015, 4. Thus, the KAPA data suggests that the use of sticky-end adapters, such as what Schmitt discloses, does not in and of itself teach or suggest the tagging efficiency limitations. Moreover, the record shows that tagging efficiency depends on a variety of other factors, including the quality of the input DNA. The KAPA data sheet states that tagging efficiency “can be significantly lower for DNA of lower quality.” Ex. 1015, 4. Fisher also explains that “the efficiency of adaptor ligation varies between samples, probably because of variation in input DNA quality.” Ex. 1031, 5–6. Petitioner’s argument that the DNA the KAPA data sheet refers to as “lower quality” is “from formalin-fixed, paraffin-embedded (‘FFPE’) samples (well known for having chemically damaged DNA)” is unavailing. See Reply 25–26 (citing Ex. 1098 ¶¶ 96–98). First, neither Petitioner, nor its declarant, address the similar teaching in Fisher. Second, even if the specific type of lower quality DNA in the KAPA data sheet is different, the salient point, i.e., that tagging efficiency depends on DNA quality, remains unrebutted. This is significant because Petitioner does not sufficiently address how the quality of the cfDNA of Narayan compares to the quality of the genomic DNA samples of Meyer and Schmitt or how that would affect the expected tagging efficiency. Petitioner’s assertion that “significant quantities of cfDNA could be isolated from blood samples” (see Reply 26), fact that a significant quantity of cfDNA could be obtained does not show that the quality of that DNA is similar such that a POSA using such would have expected to achieve a tagging efficiency similar to that in Meyer.” slip op. at 40

    • Strike new argumentNew argument disregardedDenied

      “We are not persuaded. First, this is an inappropriate new argument. The Petition presents a different mapping, alleging that the “duplex tag” comprises both the endogenous end sequence of the cfDNA molecule and the 3-mer barcode of Schmitt’s hybrid tag embodiment. Pet. 27 (“the duplex tags comprise both the fragment DNA end sequences and ‘a shorter n-mer tag’ to serve as ‘unique molecular identifiers’”) (quoting Ex. 1083 ¶ 30, Ex. 1002 ¶¶ 162–163); see also Tr. 62:13–63:19 (Petitioner’s counsel noting he was unaware of any explicit statement in the Petition that Schmitt’s duplex tag comprised just the 3-mer without the end sequence). Nor did Petitioner regarding element 1(b). See Reply 8–10. Rather, consistent with the mapping in the Petition, the Reply identifies “Schmitt’s hybrid tags,” i.e., the combination of the endogenous end sequence and the n-mer, as the duplex tags in element 1(b). See Reply 8 (urging that “duplex tags” are “tags that differently label the complementary strands,” which “is precisely what Schmitt’s hybrid tags do”). Because this argument was not previously presented, Patent Owner has not been afforded a sufficient opportunity to address it. Thus, Petitioner’s new argument excluding the end sequences in Schmitt’s hybrid tag embodiment from the alleged “duplex tags comprising molecular barcodes” has been waived. Second, even if we were to consider it on the merits, Petitioner’s new mapping for element 1(b) is inconsistent with Petitioner’s allegations for element 1(e). Element 1(e) recites “reducing or tracking redundancy” in sequence reads “using at least sequencing information from the molecular barcodes of the duplex tags to determine distinct cfDNA molecules.” Ex. 1001, 61:26–30. For these limitations, the Petition points to Schmitt’s grouping of reads into families based on their SMI and asserts that Schmitt determines distinct cfDNA molecules based on “the complementary nature of the SMI on the two strands of the duplex.” See Pet. 30–32 (internal quotations omitted). Thus, like Petition’s mapping for element 1(b), Petitioner’s allegations for element 1(e) rely on a duplex tag that includes both the 3-mer and the end sequence of the cfDNA molecule. Petitioner has not sufficiently explained, much less shown by a preponderance of the evidence, that Schmitt teaches or suggests the limitations in element 1(e) based on its new mapping of the 3-mer alone as duplex tags.” slip op. at 25

      “However, Maersk’s other two seal barriers—a ring seal, and a production packer—both appear to be passive barriers. See Ex. 2002 ¶ 60 (annotating Ex. 1019 to identify the ring seal); Ex. 1031 ¶ 33 (stating that passive barriers “include, inter alia . . . packers”). Dr. Hilbert does not explain persuasively why adding a third passive barrier would materially improve the sealing versus Maersk’s three existing barriers, so as to justify the extensive modifications required to re-route the annular fluid through the bore stab. See Ex. 1031 ¶¶ 33–35; id. ¶¶ 13–44 (discussing some of the modifications required). Further, Mr. Parks persuasively testifies, in opposition to Dr. Hilbert’s motivation testimony, that “deeper wells and increased annulus fluid pressure would not have led a [person of ordinary skill in the art] to modify Maersk to provide additional protective barriers.” Ex. 2002 ¶¶ 58, 60–63 (emphasis added). Some of this testimony has already been cited above. Additionally, Mr. Parks notably served on the editorial committee for API 17D. See id. ¶¶ 6, 63. He testifies that a person of ordinary skill in the art would have “recognized that API 17D does not support” Dr. Hilbert’s testimony, “because API 17D’s two-barrier requirement is not dependent on depth or pressure.” Id. ¶ 62 (citing Ex. 1022, 158 (§ 9.2.7)) (emphasis added). In particular: “there are practical considerations underlying the API 17D requirement for two barriers, and the lack of any specification for more than two barriers.” Id. ¶ 63. This testimony is supported by API 17D, which requires a minimum of two seal barriers for any system with a rated working pressure falling within the entire 5000–15000 psi range contemplated by API 17D.

      “We start our analysis with the claim language. The claim term in dispute is simply a “cylindrical” outer surface. The parties do not cite, and we do not discern, any other contextual claim language that might elucidate or limit the plain and ordinary meaning of “cylindrical.” Petitioner’s gloss on this term as connoting “an overall cylinder-like shape” is an unpersuasive attempt to broaden the meaning of the plain term “cylindrical.” It also would unhelpfully replace our present inquiry (What is a “cylindrical outer surface”?) with yet another inquiry (What is “an overall cylinder-like shape”?). Turning to the ’921 patent specification, we find that it discloses three different and distinct cylindrical outer surfaces: outermost cylindrical surface 102S, first cylindrical outer surface 102X, and second cylindrical outer surface 102Y. See Ex. 1001, Fig. 6, 3:47–51, 3:65–4:5. The distinctness of these three surfaces can be seen in Figures 5, 6, 8, 9, and 10. Petitioner’s attempt to combine these three distinct outer cylindrical surfaces, into one allegedly cylindrical outer surface (see Petitioner’s yellow annotations to Figure 6, supra), is not supported by the ’921 patent specification, which never describes the entire axial extent of the outer surface of bore stab body 102 as being “cylindrical.”” slip op. at 12
