The person of ordinary skill in the art is a hypothetical person presumed to have known the relevant art at the time of the invention. In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995). In determining the level of ordinary skill in the art, we may consider certain factors, including: “(1) the educational level of the inventor; (2) type of problems encountered in the art; (3) prior art solutions to those problems; (4) rapidity with which innovations are made; (5) sophistication of the technology; and (6) educational level of active workers in the field.” Best Med.

    “The ’750 patent states that “the fluid pathway can be a radially serpentine fluid pathway which causes the fluids received in the off axis chamber to flow back and forth around a radius of the off axis chamber,” also using “radially serpentine fluid pathway” to refer to this rotation around the chamber radius “while also traversing a length of the off axis chamber.” Ex. 1001, 4:34–41 (emphasis added). This is the only description of “radially” serpentine flow in the ’750 patent. Notably, the ’750 patent does not use “radially” or “serpentine” to describe a fluid pathway “which causes the fluids to spiral around the central chamber within the off axis chamber along a length of the off axis chamber,” instead referring to such a fluid pathway as a “helical fluid pathway.” Id. at 4:41–44. See CAE Screenplates, Inc. v. Heinrich Fiedler GmbH & Co. KG, 224 F.3d 1308, 1317 (Fed. Cir. 2000) (“In the absence of any evidence to the contrary, we must presume that the use of . . . different terms in the claims connotes different meanings.”); Bd. of Regents of the Univ. of Tex. Sys. v. BENQ Am. Corp., 533 F.3d 1362, 1371 (Fed. Cir. 2008) (“Different claim terms are presumed to have different meanings.”). Inst. Dec. 11–12. We explained that the flow path depicted above, which is equivalent to that of Figure 14 of the ’750 patent, “flows circumferentially about the central chamber.” Id. at 14. We maintain this interpretation. Stated differently, the depicted flow is around a longitudinal axis of the chamber. See MTA PG 6 (describing the flow path depicted above as “a back and forth flow path around a longitudinal axis of the off axis chamber; that is, a circumferentially serpentine pathway”); see also Ex. 2003 ¶ 40 (Dr. Neitzel describing the flow path depicted above as “a back and forth flow path around a longitudinal axis of the off axis chamber”). The flow is not around a radius of the chamber, which Patent Owner recognizes is required for a flow path to be radially serpentine. See PO Resp. 10 (“Patent Owner agrees with the Board’s conclusion in the [Institution Decision] that ‘radially serpentine’ as recited in the claims of the ’750 patent means a back and forth flow around a radius of the off axis chamber.” (citation modified)); PO Sur-reply 2 (agreeing that “radially serpentine” requires “a back and forth flow around a radius of the off axis chamber”).” slip op. at 14

    “We agree with Patent Owner that neither Petitioner nor its witness, Mr. Nixon, has explained adequately how Thurler’s disclosure of its tube e being perforated for two thirds of its length “contemplates other lengths of perforations.” See Pet. 48; Ex. 1013 ¶ 212. Such conclusory assertions fail to apprise us of why an ordinarily skilled artisan would have been motivated to modify Thurler’s device in contradiction to Thurler’s explicit disclosure. We are also not persuaded by Petitioner’s proffered reasoning for modifying Thurler’s device. First, the modification is not a matter of design choice because the perforations allow the gases generated by firing the projectile to pass into the space between tubes e and g where they partially expand. See Ex. 1015, 1:84–91. Thus, modifying the number of perforations necessarily affects the flow of gases through the device. Next, neither Petitioner nor Mr. Nixon explains adequately how reducing the amount of perforation in tube e results in an increased fluid length. See Pet. 49; Ex. 1013 ¶ 213. Rather, although less fluid may enter into tube e with Petitioner’s modification, it appears that that fluid would travel the same distance along tubes e and h as in Thurler’s unmodified device. Finally, neither Petitioner nor Mr. Nixon explains adequately how limiting the amount of gases generated by firing the projectile from entering the expansion zones of tubes g and h provides any benefit. To the contrary, limiting the amount of gases in the manner suggested by Petitioner would reduce the suppression of such gases, resulting in a less effective device. Moreover, Thurler discloses that “there is still a space of a few millimeters between [tubes] e and g which is necessary” to prevent the application of “pressure on the projectile causing the same to deviate.” Ex. 1015, 1:106–2:3. Thus, Petitioner’s modification would not result in the passage of gases occurring only at the first three of Thurler’s tubular sleeves as asserted by Petitioner. Additionally, in the Institution Decision, we explained that Petitioner did not provide adequate reasoning to support the proposed modification of Thurler’s device regarding parent claim 1 to have concentric tubes around the central tube e. See Inst. Dec. 29–31. This shortcoming, which we maintain, carries through to dependent claim 6. Accordingly, for the foregoing reasons, Petitioner has not shown, by a” slip op. at 26

    “We agree with Petitioner that the amendment is broadening. Petitioner’s witness testified that he “wouldn’t call a BB gun a high energy device or a high energy weapon.” Paper 33, 18:4–6. Thus, per Petitioner’s witness, use of a BB gun would not be covered by claim 22, no matter what is discharged from the BB gun. However, if high energy material is discharged from that same BB gun, that use would be covered by proposed substitute claim 43 (assuming the other claim recitations were met). See id. at 21:10–12 (Dr. Neitzel agreeing that “if something produces a high energy material, it automatically is a high energy weapon”). Thus, by deleting “high energy device” and replacing that language with “weapon,” proposed substitute claim 43 impermissibly broadens the scope of claim 22. See Sisvel Int'l S.A. v. Sierra Wireless, Inc., 81 F.4th 1231, 1241 (Fed. Cir. 2023) (“But if a substitute claim ‘is broader in any respect it is considered to be broader than the original claim even though it may be narrower in other respects.’” (citation modified) (quoting Hockerson-Halberstadt, Inc. v.

    “Independent claims 1 and 19 recite a guide RNA or crRNA molecule having “gRNA functionality comprising associating with a Cas protein and targeting the gRNA:Cas protein complex to the target sequence.” Ex. 1001, 257:42–44, 259:5–7. This claim language makes clear that the recited “gRNA functionality” requires a molecule that can: (1) associate with a Cas protein, and (2) target that complex to a target sequence in a polynucleotide. To the extent Petitioner suggests that a gRNA “need only bind to the Cas protein” to have “gRNA functionality,” we disagree because the claims additionally recite the above-quoted targeting functionality. See Reply 16 (emphasis added). At the same time, we agree with Petitioner that “a gRNA need not cleave the target DNA” to have the claimed “gRNA functionality.” Reply 16. The Specification defines “gRNA functionality” as “one or more functions of naturally occurring guide RNA, such as associating with a Cas protein, or a function performed by the guide RNA in association with a Cas protein” and lists various gRNA functions, e.g., “associating,” “targeting,” “binding,” “nicking,” and “cleaving,” that may be present “in certain embodiments” of the invention. Ex. 1001, 6:56–7:1. However, as noted above, the claims recite “gRNA functionality comprising” only the associating and targeting functions. Thus, while a molecule may have additional functions such as cleaving a target polynucleotide, it need only exhibit the recited “associating” and “targeting” functions to have the “gRNA functionality” in claims 1 and 19. Our determination that “gRNA functionality” requires the recited “associating” and “targeting” functions, but not additional, unrecited functions such as cleaving, is also consistent with the parties’ position that the claim language has its plain and ordinary meaning. See Pet. 17; Resp. 24. The parties do not dispute the construction of any other terms, nor do we discern that any further claim construction is necessary to resolve the issues in this proceeding.

    “Second, even if those sequences were truncated, the record does not support Patent Owner’s argument that a POSA would doubt that they have gRNA functionality. Patent Owner’s argument is premised on Dr. Marshall’s testimony that these sequences “are truncated to a point that would render them nonfunctional.” Ex. 2025 ¶ 200. But the references he cites do not support that position. See Ex. 2025 ¶ 202 (citing Ex. 1033 (“Fu”); Ex. 2044 (“Cencic”); and Ex. 2045 (“Mali”)). To the contrary, Fu evidences that “truncated gRNAs, with shorter regions of target complementarity <20 nucleotides in length” are functional and that truncation to 17 nt is beneficial. Ex. 1033, Abstr.; see also id. at 283 (“[W]e found that [truncated] gRNAs with 17 or 18 nucleotides of complementarity generally function efficiently at the intended target site and have improved specificities.”). Cencic and Mali likewise do not suggest that a 17 nt VT domain would lack gRNA functionality.

  • RehearingRehearing, grantedGranted

    “recites “in the absence of an anthracycline derivative.” In the Petition and the Preliminary Response, neither party proposed a construction for that term. Patent Owner, however, argues that “[e]ven if a person of ordinary skill would have chosen to combine an anti-ErbB2 antibody and a taxoid, there is no reason an ordinarily skilled artisan would have avoided anthracyclines as part of that treatment.” Prelim. Resp. 52 (emphasis added). In our Decision denying institution, we agreed with Patent Owner, stating that evidence of the record is “insufficient to suggest that an ordinary artisan would have avoided anthracyclines while pursuing the combination therapy with anti-ErbB2 antibody and a taxoid in a treatment regimen for humans.” Dec. 10 (emphasis added). In its Request for Rehearing, Petitioner contends that we erred in interpreting the limitation “in the absence of an anthracycline derivative” as requiring “avoidance” of an anthracycline derivative. Reh’g Req. 6. According to Petitioner, this term “is a negative limitation that is satisfied by anti-ErbB2 antibody–paclitaxel combinations that do not include an [anthracycline] derivative.” Id. at 5. After reconsidering the current record, we find Petitioner’s argument persuasive. In particular, because Baselga ’94 suggests a therapeutic composition consisting of an anti-ErbB2 antibody and paclitaxel, and does not suggest that doxorubicin must necessarily be included as part of the same treatment regimen, we are persuaded that the reference satisfies the limitation “in the absence of an anthracycline derivative.” Cf. Upsher-Smith Labs., Inc. v. Pamlab, L.L.C., 412 F.3d 1319, 1322 (Fed. Cir. 2005) (concluding the prior art anticipates a claim requiring a composition “essentially free of antioxidants,” because the prior art teaches “optional inclusion” of antioxidants, “despite no express teaching to exclude the antioxidants”).” slip op. at 17

    “In sum, Petitioner has presented sufficient evidence, for purposes of instituting trial, to show that in considering prior therapy received, an ordinary artisan would have been motivated to treat patients with ErbB2- overexpressing breast cancer by administering a combination of an anti- ErbB2 antibody and a taxoid, and “in the absence of an anthracycline derivative.”” slip op. at 18

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundInstituted

    “Petitioner, however, points to other evidence to show that prior art teaches an ordinary artisan to combine an anti-ErbB2 antibody with a taxoid. Specifically, Petitioner refers to Baselga ʼ94 for teaching that, in mouse xenografts, “individual treatment with either anti-HER2 4D5 or paclitaxel alone resulted in 35% growth inhibition whereas the combination ‘resulted in a major antitumor activity with 93% inhibition of growth’ without increasing toxicity.” Id. at 45 (citing Ex. 1005 at 4). Similarly, Baselga ’96, citing Baselga ’94, teaches that “[i]n preclinical studies, both in vitro and in xenografts, rhuMAb HER2 markedly potentiated the antitumor effects of several chemotherapeutic agents, including … paclitaxel without increasing their toxicity.” Id. at 44 (quoting Ex. 1004, 15). Based on these teachings, we are persuaded that an ordinary artisan would have had a reason to treat HER2-positive breast cancer patients with a combination of rhuMAb HER2 and a taxoid.” slip op. at 12

  • Obviousness (§103) › Motivation to combine / reasonable expectation of success › Teaching awayTeaching away not foundDecided for petitioner

    “Patent Owner argues that Exhibit 2029, which states that “breast cancers that overexpress p185 [i.e., HER2] will not respond well to Taxol,” teaches away from the claimed combination therapy. Prelim. Resp. 51 (citing Ex. 2029,5 1362). We are not persuaded on this record. In an obviousness inquiry, we must analyze the prior art as a whole, and not individually. See In re Fulton, 391 F.3d 1195, 1200 (Fed. Cir. 2004) (explaining that the question is “whether there is something in the prior art as a whole to suggest the desirability, and thus the obviousness, of making the combination”). Other evidence of record shows paclitaxel had been approved for treating breast cancer (see, e.g., Ex. 1025, 10), demonstrates synergy of paclitaxel and an anti-ErbB2 antibody in human breast cancer xenografts (see, e.g., Ex. 1005, 4; Ex. 1004, 15), and suggests clinical trials of the combination therapy (see, e.g., Ex. 1005, 4; Ex. 1004, 15). Weighing all evidence of record, we are not persuaded that prior art as a whole teaches away from combining paclitaxel and an anti-ErbB2 antibody in treating HER2-positive cancers.” slip op. at 14

Dr. Roush, on the other hand, conducts an analysis of the compound under the “Rule of 5” to determine that “5-HMT does not meet a single factor, much less two, of the rule” thus teaching the skilled artisan “away from concluding that 5-HMT had an oral absorption problem.” Resp. 28–29 (citing Ex. 2022 ¶¶ 56–58, 87, 92). At oral hearing, Patent Owner restated that the analysis under the Rule of 5 indicates that 5-HMT was “not even close to being a problem . . . for all four of these properties, 5-HMT says there’s no red flags; there’s no problem,” and that “Dr. Patterson admitted in his deposition, 5-HMT does not violate the Rule of Five.” Tr. 67:35–68:3; 68:17–21; see Ex. 2020, 180:14–181:14. Regarding Petitioner’s reliance on the statement in Brynne that “[t]olterodine is tenfold more lipophilic than 5-HM[T], and consequently tolterodine penetrates membranes more rapidly,” Patent Owner does not appear to dispute the substance of that statement. Although such a statement illustrates a relative relationship between the lipophilicity of 5-HMT and tolterodine, it does not demonstrate that the lipophilicity of 5-HMT would have presented an absorption problem that would have led one of ordinary skill in the art to modify 5-HMT. Even if 5-HMT were considered by one of ordinary skill in the art to be less lipophilic than tolterodine, and thereby less rapidly absorbed, the record lacks sufficient evidence regarding the actual properties of 5-HMT for us to conclude that 5-HMT’s lipophilicity would have presented a bioavailability problem.21 For these reasons, Petitioner’s assertion that 5-HMT “may have bioavailability concerns” that would have prompted one of ordinary skill in the art to modify 5-HMT is unpersuasive.

    “On the complete record before us, we are unpersuaded that Petitioner carries its burden of demonstrating that 5-HMT has a bioavailability problem that would have motivated one of ordinary skill in the art to modify its structure. Regarding the lipophilicity profile of 5-HMT, Petitioner does not provide, or attempt to provide, any actual (as opposed to relative) data concerning the bioavailability of 5-HMT. Cf. supra § II.D.2 (Brynne comparing lipophilicity of tolterodine to lipophilicity of 5-HMT). Although data is not required, and although we do not find that absence of data alone to be fatal to Petitioner’s position on this issue, the absence of any data concerning the actual bioavailability of 5-HMT leaves Petitioner’s argument solely supported by expert testimony. We now turn to the contradictory statements of the parties’ experts. Following our weighing of the experts’ testimony, we find that Dr. Roush’s testimony better addresses the issue at hand and we credit that testimony over Dr. Patterson’s testimony. Dr. Patterson opines generally that the “presence of two hydroxyl groups around the left most aromatic ring . . . would have created a product likely to have decreased oral bioavailability compared to tolterodine because of its hydrophilicity and thus lower than acceptable lipophilicity” (Ex. 1003 ¶ 112), and that it “would [have been] a matter of routine experimentation” to confirm that 5-HMT could have significantly less bioavailability than its parent, tolterodine” (Ex. 1003 ¶ 115). Dr. Patterson, however, did not perform any experiments to confirm 5-HMT’s oral bioavailability, and cites to no further evidence to support his opinions. See Ex. 2022 ¶ 92; compare Brynne (Ex. 1011) discussed supra § II.D.1.” slip op. at 30
