“V. CONCLUSION Petitioner has, at this stage, established that it will more likely than not prevail in showing that at least one of the challenged claims is unpatentable. This determination is, however, based on a preliminary record and is not final on any issues of patentability. We will make a final determination on the patentability of the challenged claims, as necessary and applying the preponderance of the evidence standard, based on a fully developed record through trial.

“limited to Patent Owner’s proposed “from about 50 Daltons to about 1,500 Daltons.” The cited evidence relied on in the Pomper Declaration to define “low molecular weight” as a term well accepted in the chemical arts relates to metabolomics and metabolites. See Ex. 1002, 169, (specifically, ¶ 17 of Dr. Pomper’s declaration). Patent Owner admits that Dr. Pomper’s testimony is about molecules that differ from the claimed imaging and radiotherapeutic agents targeting FAP-α, but argues that the testimony is still relevant for purposes of explanation. Prelim Resp. 21. While it may be relevant, the testimony is not persuasive in light of the Specification. We find the uncontested fact that several of the B moieties alone—without the A moiety or L linker—specifically identified in the ’233 patent fall outside of Patent Owner’s proposed definition persuasive, as we normally do not interpret claim terms in a way that excludes examples disclosed in the specification. See, e.g., Verizon Servs. Corp. v. Vonage Holdings Corp., 503 F.3d 1295, 1305 (Fed. Cir. 2007) (rejecting proposed claim interpretation that would exclude disclosed examples in the specification). The cases cited by Patent Owner supporting that a claim term may be construed to exclude embodiments where the prosecution history supports such construction are factually distinguishable from the instant case as they regard instances of specific prosecution history disclaimer, clear prosecution disavowal, or relate to a specific definition of the terms in the Specification for the term being construed. Here, “low molecular weight” is not defined in the Specification, but, as Petitioner argues (see Pet. 21–25) is characterized as “demonstrat[ing] faster pharmacokinetics and a higher specific signal within clinically convenient times after administration” and that it “can be synthesized in radiolabeled form more easily.” Ex.1001, 13:33–50, 14:56– 16:14, 17:9–20. We are persuaded by the testimony of Dr. Zeglis, Petitioner’s declarant, that compounds weighing over 1500 Da may share those same behaviors, along with certain identified B moieties disclosed as embodiments.

“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.

“We do not discern a substantive difference between the parties’ respective definitions for the level of ordinary skill in the art. Although Petitioner states a person of ordinary skill in the art must have one to two years of postdoctoral research experience and Patent Owner’s definition requires at least five years of research experience, Patent Owner’s definition does not indicate a specific time for that research (i.e., it could include research during a doctoral program). On this record, we find the parties’ respective definitions to be equivalent and consistent with the level of ordinary skill in the art as reflected by the prior art in this proceeding. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown” (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985))). Moreover, we find on this record that Dr. Shaner and Dr. Burgos are both qualified to opine from the perspective of a skilled artisan as both are persons of at least ordinary skill in the art, based on either party’s definition.

“Patent Owner states that it “agrees that the claim terms of the ’346 Patent should be given their ordinary and customary meaning.” Prelim Resp. 20. We interpret Patent Owner’s statement to mean that it agrees with Petitioner’s proposed constructions of “endogenous non-transfected mutant” and “effective amount.” Because Petitioner’s construction of “endogenous non-transfected mutant” is consistent with the ’346 patent’s express construction of the term, that construction in this proceeding.” slip op. at 7

“limitation of each of the challenged claims is not adequately supported by the Mankin Application. Although the Mankin Application does generally describe herbicidal compositions that “comprise an herbicidal effective amount” of at least one ACCase herbicide (Ex. 2034 ¶ 233), that generic disclosure is not sufficient written description support for the specific effective amount recited in the claims. Indeed, we agree with Petitioner that the Mankin Application does not disclose any effective amounts of quizalofop within the claimed range, let alone one that causes less than 10% injury.

“We find Petitioner has shown sufficiently that the “effective amount” limitation of each of the challenged claims is not adequately supported by the Mankin Application. Although the Mankin Application does generally describe herbicidal compositions that “comprise an herbicidal effective amount” of at least one ACCase herbicide (Ex. 2034 ¶ 233), that generic disclosure is not sufficient written description support for the specific effective amounts recited in the claims. Indeed, we agree with Petitioner that the Mankin Application does not disclose any effective amounts of any of the recited herbicides within the claimed ranges, let alone one that causes less than 10% injury. See Ex. 1002 ¶¶ 90, 91. 94; Ex. 1013 ¶¶ 128, 237 (Table 1), 248, Fig. 17. description is satisfied because the Mankin Application’s disclosure of an herbicide tolerance study for a DIM herbicide would have led a person of ordinary skill in the art to the specific effective amounts of the FOP herbicides recited in the claims. Prelim. Resp. 72–73. Nor are we persuaded that there is adequate written description support because a person of ordinary skill in the art would have been able to ascertain the effective amounts for each herbicide based on the knowledge in the art. Id. at 73. That is not the test for written description. “It is not sufficient for purposes of the written description requirement of § 112 that the disclosure, when combined with the knowledge in the art, would lead one to speculate as to modifications that the inventor might have envisioned, but failed to disclose.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 1997). Rather, “[e]ach application in the chain must describe the claimed features.” Id.” slip op. at 15

“We note that Petitioner does not appear to consider the knowledge of a person of ordinary skill in the art in evaluating the amount of guidance needed to enable the claimed invention. As our reviewing court states, “[a] patent need not teach, and preferably omits, what is well known in the art.” Falkner v. Inglis, 448 F.3d 1357, 1365 (Fed. Cir. 2006) (citation omitted). Although the ’345 patent does not provide a specific working example of the G2096S mutation, we are not persuaded on this record that that necessarily weighs heavily in favor of undue experimentation given the prior knowledge in the art that that mutation confers herbicide tolerance to rice plants and the deposit of the G2096S mutation seed, as taught by Hinga and Hinga2013.

“Analysis Anticipation requires that “each and every element as set forth in the claim is found, either expressly or inherently described, in a single prior art reference.” In re Robertson, 169 F.3d 743, 745 (Fed. Cir. 1999) (citation omitted). “To establish inherency, the extrinsic evidence ‘must make clear that the missing descriptive matter is necessarily present in the thing described in the reference, and that it would be so recognized by persons of ordinary skill.’” Id. (citation omitted). Moreover, to anticipate, a prior art reference must “disclose[] within the four corners of the document not only all of the limitations claimed but also all of the limitations arranged or combined in the same way as recited in the claim.” Net MoneyIN, Inc. v.
