“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. VI. ORDER In consideration of the foregoing, it is hereby: ORDERED that, pursuant to 35 U.S.C. § 324(a) post grant review of claims 1–4 of the ’233 patent is hereby instituted on the grounds set forth in the Petition, commencing on the entry date of this Order, and pursuant to 35 U.S.C. § 324(d) and 37 C.F.R. § 42.4, notice is hereby given of the institution of a trial; and” slip op. at 40

“In addition, the opinion stated in the Pomper Declaration that “the term of ‘low molecular weight’ is well accepted in the chemical arts” and the declarant “recognize[s] that low molecular weight compounds would have a molecular weight of typically from about 50 Daltons to about 1,500 Daltons” is offered by a co-inventor. We, as factfinder, have discretion to weigh the credibility of expert witnesses and to give each item of evidence such weight as appropriate. See In re Am. Acad. of Sci.

“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.

“We further interpret “collecting the nucleic acid probes” to mean “releasing all or a portion of the nucleic acid probe bound to the at least one target analyte through application of a force followed by retrieval of the released probe or portion of the probe.” The question then becomes whether So-465, which teaches replication of a probe that was bound and then at least partially released to make genomic amplicons, followed by collection of those genomic amplicons, anticipates collection of probes as recited in claims 1 and 16. On this record, we do not see sufficient evidence that the genomic amplicons disclosed in So-456 that Petitioner identifies as “captured” were ever “bound to the analyte” in part or in whole as required by the claim language, but rather were amplified in situ from the probe or partial probe that was released. Ex. 1005 ¶¶ 181–183. In particular, the process of So-456 differs from the ’689 patent claims in that the extension reaction to incorporate the tissue-identifying nucleic acid sequence in So-465 occurs after the identifier nucleotide is cleaved from the tissue sample. “Anticipation requires that all of the claim elements and their limitations are shown in a single prior art reference.” In re Skvorecz, 580 F.3d 1262, 1266 (Fed. Cir. 2009). Petitioner has not demonstrated that So-456 teaches this claim limitation or otherwise demonstrates that this limitation would have been inherent in the disclosure of So-456 for claims 1 and 16.

Resp. 7–8 (“Thus, as reflected in Hogan and Hotopp [(co-authored by Dr. Hausinger)], skilled artisans understood the structure-function relationships of Group II αKG-dependent dioxygenases . . . .”); Ex. 1029 (Hotopp 2002)). During prosecution, Dr. Wright’s declaration relied on Dr. Hausinger’s research. See, e.g., Ex. 1008, 462 (Wright I ¶ 13 (citing Hotopp)), 658 (Wright II ¶¶ 10–13 (describing the research in Hogan and Hotopp as that of “skilled artisans”)). And, Applicant’s other declarant, Dr. Nair, who testified about academic and prior work history focused on chemistry, biochemistry, and enzymology without significant background in subjects like “controlling weeds” about which Patent Owner questions Dr. Hausinger’s qualifications. See, e.g., Ex. 1008, 590–591.17 Patent Owner will have the chance to cross-examine Dr. Hausinger in this proceeding. If Patent Owner feels we should discount Dr. Hausinger’s testimony due to lack of qualifications, it may raise such argument in trial. For now, we apply Petitioner’s proposed POSA level, with the clarifications noted above, which appears consistent with the level of skill shown in the prior art references of record. See Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007).” slip op. at 22

“The two proposed definitions of the ordinarily skilled artisan are very similar, except that Patent Owner’s description more-specifically defines the field of experience of the artisan. At this stage in the proceedings, we accept and use Petitioner’s proposed definition of the ordinarily skilled artisan, as being both generally unopposed by Patent Owner and inclusive of Patent Owner’s supplemental definition. It appears that Petitioner’s language “at least two years of experience in the discovery, development, and design of therapeutic antibodies for use as potential treatments in human disease” includes Patent Owner’s proposed level of experience. Pet. 12–13. We also take into account the level of skill in the art reflected in the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Corp., 755 F.2d 158, 163 (Fed. Cir. 1985)). Our decision whether to institute does not turn on which party’s definition of the skilled artisan is used, and our determinations would be unchanged if we applied Patent Owner’s supplemented definition. Further, we note that evidence may be presented as the case progresses to support some other proposed definition of the skilled artisan, which may influence our determination of this issue.

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed petitioner constructionDecided for petitioner
“At this stage of the proceeding, we determine Petitioner’s construction is most consistent with the plain ordinary meaning of “about” and the intrinsic evidence. The claim recites that the carbon chain length of the resulting bio-alkene is “about 5 to about 20.” Ex. 1001, claim 1 (emphasis added). We agree with Petitioner that use of the term “about” indicates a lack of specificity with respect to the claimed range. See Cohesive Techs., Inc. v. Waters. Corp., 543 F.3d 1351, 1368 (Fed. Cir. 2008) (“When ‘about’ numeric boundary to the specified parameter.”) (internal quotations omitted). In other words, the claim term “about 5 to about 20” does not require precisely 5 to 20 carbons. Moreover, we agree that a carbon atom in a compound is not divisible. Keeping these principles in mind, we find “about 5” at the lower end of the range encompasses at least a carbon chain length of 4, and “about 20” at the upper end of the range encompasses at least a carbon chain length of 21. We also agree with Petitioner that the prosecution history of the parent application supports construing “about” to encompass one additional carbon atom, as evidenced by the amendment after allowance amending the term “carbon chain length of about 8” to “carbon chain length of 7.” See Ex. 1006, 335. Thus, the intrinsic evidence supports Petitioner’s construction and the plain ordinary meaning of “about.”” slip op. at 8

“In general, “the preamble does not limit the claims.” Allen Eng’g Corp. v. Bartell Indus., Inc., 299 F.3d 1336, 1346 (Fed. Cir. 2002). Moreover, “where a patentee defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention, the preamble is not a claim limitation.” Rowe v. Dror, 112 F.3d 473, 478 (Fed. Cir. 1997). Considering the record before us, the preamble of claim 1 merely recites a purpose or intended use for the claimed method. In general, step (a) in the body of claim 1 entails obtaining sequence data from at least one biological sample from a subject. In step (b) the sequence data is used in to identify a set of genetic variants present in the biological sample. Step (c) entails creating a probe set corresponding to identified genetic variants. In step (d) the probe set is used to selectively enrich or amplify those variants if present in a second biological sample from the same or related individual, and thereby create a sequencing library. This library is sequenced in step (e) to identify the presence or absence of at least a subset of the genetic variants identified in step (b). As such, steps (a) through (e) define a complete invention, with the preamble merely stating a 4 To the extent Patent Owner maintains that the preamble is both limiting and distinguishes over the applied prior art, Patent Owner should clearly and explicitly identify during trial how it proposes the preamble should be construed—identifying evidentiary support for such construction according to well-established precedents. out the positively recited steps of the claim.
