“Based on the information presented, we agree with Patent Owner that the asserted prior art itself is sufficient to demonstrate the level of skill in the art at the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself can reflect the appropriate level of ordinary skill in the art). We do not find it necessary to define the level of skill in the art at the time of the invention at this time.

“Based on the above, we agree with Patent Owner that many of the arguments raised by the Examiner are highly similar to the challenges in this proceeding, particularly the written description challenge. However, some arguments differ. For instance, Petitioner’s enablement argument identifies that, contrary to Applicant’s statement during prosecution reproduced above, amino acids and protein structure outside the disclosed AAD-12 motif can also affect the activity of the claimed dioxygenases to degrade phenoxy auxin and pyridyloxy auxin. See Ex. 1003 ¶¶ 42–50, 79 (Dr. Silverstone describing the mechanics of protein binding and explaining why the ’055 patent disclosure fails to provide sufficient information to the skilled artisan to know which amino acids could be changed while retaining the ability to enzymatically degrade both phenoxy and pyridyloxy auxin herbicides). See also Pet. 27–34 (asserting, e.g., 85% homology to AAD-12 motif alone is insufficient to predict enzymatic degradation activity). While the Examiner’s rejections regarded the disclosure corresponding to the ability to degrade herbicides, the Examiner plainly relied on Applicant’s statements that the AAD-12 motif’s structure alone was responsible when deciding to withdraw the rejection. Ex. 1002, 355. The Examiner did not have the additional testimony supplied by the Silverstone declaration explaining otherwise. See Ex. 1003 ¶¶ 42–50, 79. Petitioner, through Dr. Silverstone, also addresses the effort the skilled artisan would have needed to undertake to determine what proteins outside of the AAD-12 motif would affect the ability of homologues to enzymatically degrade the recited herbicides, and provides evidence for consideration regarding the lack of a clear link between the AAD-12 motif and the ability to enzymatically degrade both phenoxy and pyridyloxy auxin herbicides. Ex. 1003, 347. Therefore, the arguments are not entirely overlapping. And while these issues do in part overlap with Petitioner’s arguments pertaining to enablement, we agree with Petitioner that the Examiner did not complete a written Wands analysis. Although we conclude that the arguments are not entirely overlapping, we proceed to the second step in the analysis, for completeness.” slip op. at 13

“85% identity as “highly identical” in this field and that the “conserved motif residues comprise ‘the active site that is essential for catalytic activity.’” Prelim. Resp. 31 (citing Ex. 1001, 11:1–6)). However, on the record before us, we are unpersuaded that this is sufficient because the Specification lacks disclosure supporting that a polypeptide of, for example, 86% identity to SEQ ID NO: 2 would retain the ability to degrade herbicides if the 5 amino acids in the general formula of HX109D(X)111-134 T(X)136-261H(X)263-272R, and the required chain lengths are present. In this regard we are persuaded by the testimony of Dr. Silverstone (Ex. 1003 ¶¶ 48–93) regarding the limitations of the disclosure of the ’055 patent and the lack of information supporting the skilled artisan in understanding that the inventor possessed the entire claimed genus (e.g., lack of example at lower end of sequence identity and lack of information to assist the skilled artisan in predicting whether an α-ketoglutarate-dependent dioxygenase would interact with or degrade either phenoxy auxin herbicides and/or pyridyloxy auxin herbicides). Dr. Silverstone testifies, and we are persuaded on this record, that the skilled artisan would not have read the guidance in the disclosure and understood that the inventors possessed the ability to design a modified SEQ ID NO: 2 at the 85% identity level that retained the function of degrading the recited herbicides, let alone the full scope of the claimed genus. Id. Patent Owner argues that Dr. Silverstone’s testimony that conserved amino acids of the AAD-12 motif are present in other α- ketoglutarate-dependent dioxygenases but do not have the claimed dual activity (Ex. 1003 ¶ 48) is misplaced because it “ignores that the location and spacing of those residues in other αKG-dependent dioxygenases differ from those in the AAD-12 motif.” Prelim. Resp. 38. However, Patent Owner offers no evidence that supports its argument. Id. It is thus unpersuasive.” slip op. at 36

“Here, we agree with the parties that the preamble of claim 1 is limiting. The preamble provides context for the requirement of claim 1 that administration of the semaglutide is “to a subject in need thereof.” See Ex. 1001, 35:42–44. The preamble, when read in the context of the entirety of claim 1, recites a limitation of administering semaglutide to a subject with type 2 diabetes. Based on the constructions of the preamble provided by the parties, it appears they agree that the preamble does not require any particular level of efficacy. We agree. The Specification of the ’462 patent makes clear that “treatment” or “treating” as used in the ’462 patent does not require any particular degree of efficacy as these terms include the “full spectrum” of treatments for a condition. See Ex. 1001, 5. For instance, the Specification of the ’462 patent provides: In one embodiment the term “treatment” or “treating” as used herein means the management and care of a patient for the purpose of combating a condition, such as a disease or a disorder. In one embodiment the term “treatment” or “treating” is intended to include the full spectrum of treatments for a given condition from which the patient is suffering, such as administration of the active compound to alleviate the symptoms or complications; to delay the progression of the disease, disorder or condition; to alleviate or relieve the symptoms and complications; and/or, to cure or eliminate the disease, disorder, or condition as well as to prevent the condition.

“In an [inter partes review], the petitioner has the burden from the onset to show with particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (citing 35 U.S.C. § 312(a)(3) (2012) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”)). This burden of persuasion never shifts to Patent Owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015) (discussing the burden of proof in inter partes review). A claim is unpatentable under 35 U.S.C. § 103 if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence (1966). In analyzing the obviousness of a combination of prior art elements, it can be important to identify a reason that would have prompted one of skill in the art “to combine . . . known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418. A precise teaching directed to the specific subject matter of a challenged claim is not necessary to establish obviousness. Id. Rather, “any need or problem known in the field of endeavor at the time of invention and addressed by the patent can provide a reason for combining the elements in the manner claimed.” Id. at 420. Accordingly, a party that petitions the Board for a determination of unpatentability based on obviousness must show that “a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention, and that the skilled artisan would have had a reasonable expectation of success in doing so.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1381 (Fed.

“On the record before us, however, Dr. Flatt’s assessment of the relative benefit one of ordinary skill in the art would have accorded the higher Ki of mono-substituted compound 3 as compared to the “much longer plasma half-life” of Dong’s bi-substituted compounds is at odds with Dong’s selection of bi-substituted compound 4 for clinical trials. See Ex. 1013, 670– 671 (Table 1). We are also skeptical of Dr. Flatt’s assertion that one of ordinary skill in the art would have recognized that Dong’s substitution of Aib for alanine at position 8 “would complement and work synergistically with liraglutide’s [other] properties,” including the fatty acylation of Lys26.

“Considering the record before us, Petitioner has not shown sufficiently that one of ordinary skill in the art would be motivated to make the required modification with a reasonable expectation of success.

As discussed above, we find Petitioner’s justification for these individual steps problematic.

“Patent Owner’s argument is unpersuasive because the combination of Harris with Xing is not cumulative of Pavlakis, Harris-2015, and Damsky. Here the combination of Harris with Xing is argued in different ways compared to what was made to the Examiner. Additionally, we agree with Petitioner that Xing discloses information the Examiner indicated were absent from the prior art. See Ex. 1010, 14–15. For example, Xing teaches administering a therapeutically effective amount of an inhibitor of IL-15 or the IL-15 receptor is administered to the subject. Compare id. at 15, with Ex. 1007, 3. Xing also teaches that TM-β1-mediated blockade of CD122 prevented disease development and progression and that inhibiting IFN-γ production downstream of IL-15 through topical administration of JAK inhibitors effectively eliminated existing lesions.

“Independent claims 1 and 12 recite a guide RNA or crRNA molecule having “gRNA functionality comprising associating with a Cas protein and targeting the gRNA:Cas protein complex to a target polynucleotide.” Ex. 1001, 243:20–22, 244:28–31. 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 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 17 (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 17. 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, 6:36–40. 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 12. 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. 24–25. 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.”).

We see nothing there that suggests Dr. Furneaux agrees with Patent Owner’s position that any gRNA with a VT region of less than 20 nt is truncated. “truncated gRNA tests showed that a guide sequence of only 16 nucleotides” abolished cleavage activity); Ex. 2045, Supp. Fig. 10 (“1-3 bp 5’ [gRNA] truncations are indeed well tolerated, but larger deletions lead to loss of activity”).

“We are not persuaded. We credit the testimony of Petitioner’s expert, Dr. Sher, who explains that because of the “high degree of imprecision of Figures 2 and 6,” a POSA would be unable to reach any quantitative conclusions from the figures or “clinically distinguish” between brimonidine concentrations that differ by only five-thousandths of a percent. Ex. 1049 ¶¶ 10–18. For example, as Dr. Sher notes, there are no incremental hash marks that indicate where any non-enumerated concentrations such as 0.02% or 0.025% would fall. Id. ¶¶ 11–12. Moreover, the x-axis of both figures appears to be neither linear nor logarithmic. Id. The uncertainty of the scale of the x-axis calls into question the assumption by Dr. Noecker that the blue dot on the x-axis of Figure 6 is necessarily 0.025% as opposed to, for example, 0.02%, which is specifically called out in the Specification’s description of Figure 6 as a preferred concentration. See Ex. 1001, 19:57 (stating Figure 6 demonstrates that “the net effectiveness of brimonidine as a decongestant is greatest between about 0.01% and about 0.03%; preferably between about 0.012% and about 0.02%”) (emphasis added). Moreover, like Dr. Sher, we question the accuracy of Dr. Noecker’s statement that concentrations less than 0.03% have no rebound hyperemia. See Ex. 1049 ¶ 19 (citing Ex. 2020 ¶ 94). As seen by a magnified portion of Figure 2, reproduced below, the dark gray, solid line indicating rebound hyperemia appears to show at least some amount of rebound hyperemia below 0.03%: That is, the magnified portion of Figure 2 depicts the dark gray rebound hyperemia curve between 0.01% and 0.03% to be above the x-axis, indicating—on its face—that some rebound hyperemia occurs, contrary to Dr. Noecker’s testimony. Id. We, therefore, credit the reasoning of Dr. Sher, who explains that, in light of the imprecision of the figures, a POSA would not rely on the figures to discern when rebound hyperemia begins, but would rather rely on the Specification, which states “rebound hyperemia begins at around 0.03%.” Id. We are persuaded that those words of approximation suggest that rebound hyperemia could begin either a little less than, at, or a little more than 0.03% brimonidine. See Ex. 1049 ¶ 25. Thus, we agree with Dr. Sher that “a POSA would read the ’742 patent’s description of Figure 6 and reasonably conclude that ‘at around 0.03%’ includes 0.025%.” Id.” slip op. at 25
- Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingDecided for petitioner
“As an initial matter, we agree with the parties that the preamble of the claims is limiting. “Whether to treat a preamble as a claim limitation is determined on the facts of each case in light of the claim as a whole and the invention described in the patent.” Storage Tech. Corp. v. Cisco Sys., Inc., 329 F.3d 823, 831 (Fed. Cir. 2003). The Federal Circuit “has not hesitated to hold preambles limiting when they state an intended purpose for methods of using a compound.” Eli Lilly & Co. v. Teva Pharms. Int’l GmbH, 8 F.4th 1331, 1342 (Fed. Cir. 2021). And where, as here, the claims are directed to methods of using a composition for a specific purpose (i.e., reducing eye redness), and the method comprises a single step of administering that composition, the Federal Circuit “has generally construed statements of intended purpose in such method claims as limiting.” Id. at 1340. agree with Petitioner that it does not and find Eli Lilly to be instructive. In Eli Lilly, the preambles of the claims recite a “method for reducing incidence of or treating at least one vasomotor symptom in an individual” and a “method for treating headache in an individual.” 8 F.4th at 1335. There, the Federal Circuit held that the preambles “are not merely statements of effect but rather statements of the intentional purpose for which the methods must be performed.” Id. at 1342. Thus, the Federal Circuit did not require proof of actual clinical results from performing the claimed method, even though the claims also recited an “effective amount.” Id. The Federal Circuit held that because the specification defined an “effective amount” as an “an amount sufficient to effect beneficial or desired results” and provided examples of such results in the context of prophylactic or therapeutic uses, the claims “encompass a clinical result, [but] they do not require such a result.” Id. Here, similarly, the ’742 patent claims simply recite administering the brimonidine composition (at a concentration range) and do not recite any efficacy requirement, nor even the “effective amount” of note in the Eli Lilly claims. But, like Lilly and as explained below, the “ocular conditions” of the claims encompass prophylactic reduction of hemorrhage and hyperemia in addition to therapeutic uses. See Ex. 1001, 12:13–19. We, therefore, find the claims here do not require actual redness reduction and, thus, no clinical result is required to satisfy the claimed method. Thus, having considered the arguments and evidence presented at trial, we determine that the preamble of the claims is limiting and requires that the claimed brimonidine composition be administered with the actually reduced.” slip op. at 10
- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed petitioner constructionDecided for petitioner
“evidence presented at trial, we agree with Petitioner that the term “about 0.025%” includes 0.03%. Our construction is supported not only by intrinsic evidence, but also by extrinsic evidence that demonstrates the alleged criticality of the “about 0.025%” limitation. terms of a specific numerical range. We must, therefore, determine how broadly a POSA reading the ’742 Specification would extend the numerical range around 0.025%. In doing so, we consider the described criticality of “about 0.025%” brimonidine and its purpose to the claimed invention. See Cohesive, 543 F.3d at 1368. The ’742 patent makes clear that the purpose of the “about 0.025%” limitation in the claims is to use “low doses of highly selective a-2 adrenergic receptor agonists to achieve vasoconstriction with significantly reduced hyperemia.” Ex. 1001, 2:39–41. Furthermore, the Specification explains that there is a need for methods that provide “safe and long term vasoconstriction with reduced or minimized side effects, such as rebound hyperemia.” Id. at 2:30–33. There is no dispute that both 0.025% and 0.03% constitute low doses of brimonidine, as described by the Specification. See id. at 3:60–65 (defining “low concentrations” as “between about 0.0001% to about 0.05%”). Thus, the question is whether there is a critical distinction between the two concentrations and their ability to provide vasoconstriction with reduced rebound hyperemia.

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
