“Petitioner contends that a person of ordinary skill in the art “would have at least a Ph.D. in chemistry, metallurgy, or material science or material engineering” or, in the alternative, “would have a Bachelor of Science or Master of Science degree in one of these disciplines plus experience involving the use and design of dissolvable metal alloys for use in creating tools and other downhole parts for well drilling or completion activities.” Pet. 13–14. Patent Owner does not oppose Petitioner’s contentions regarding the level of ordinary skill in the art. PO Resp. 12 n.4. Upon review of the prior art of record and the parties’ arguments, we adopt Petitioner’s unopposed definition of the ordinarily skilled artisan as it is consistent with the prior art of record.” slip op. at 7

“With respect to claim 19, Petitioner proposes constructions for the terms “in situ precipitate” and “a plurality of particles of said in situ precipitate having a size of no more than 50 µm.” Pet. 11–12. With respect to claims 76–81, Petitioner proposes a construction for the term “wherein said additive material includes one or more metal materials selected from the group consisting of 0.1–35 wt. % copper, 0.1–24.5 wt. % nickel and 0.1–20 wt. % cobalt.” Id. at 13. Patent Owner contends no claims require construction for purposes of this Decision. PO Resp. 12 n.4, 17–18; Mot. 16–17. Upon review of the prior art of record, we determine that no claim terms require express construction for purposes of this Final Written Decision. See Realtime Data, LLC v.

“Ex. 2027, 20:25–21:5 (emphasis added). The disclosure that the “magnesium composite” of “[t]he present invention” “includes at least 50 wt% magnesium” is unambiguous and constitutes strong evidence that the inventors were not in possession of a magnesium composite with less than 50 wt. % magnesium, or additive concentrations above 50 wt. %. See SciMed Life Systems, Inc. v. Advanced Cardiovasular Systems, Inc., 242 F.3d 1337, 1343 (Fed. Cir. 2001) (noting that a description of the “present invention” as having a particular structure “is strong evidence that the claims should not be read to encompass the opposite structure”). Consistent with this conclusion, the original claims of the ’295 application all limited the additive material in the composite to 0.05 wt %–45 wt %. Ex. 2027, 26:1– 13, 29:9–15. Likewise, in each example where copper, nickel, or cobalt additives are used in the range recited in the proposed substitute claims, the magnesium composite is “over 50 wt% magnesium,” and any claims that do not require this range of magnesium are limited to an additive range of “about 0.05 wt%–45 wt% of said mixture.”8 Ex. 2027, 6:13–7:4, 7:16–19, 8 Written description support is considered from the view point of the ordinarily skilled artisan. Ariad Pharms., Inc. v. Eli Lilly and Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). Patent Owner, bearing the burden to show written description support in any priority application for which it seeks the benefit of its filing date, provides no testimony from an ordinarily skilled artisan regarding written description support in the ’295 application, or any evidence to show what such an artisan would conclude from the express disclosures of the ’295 application. Lectrosonics, Paper 15 at 7; In re NTP, 654 F.3d 1268, 1276 (Fed. Cir. 2011) (noting that “a patent’s claims are not entitled to an earlier priority date merely because the patentee claims priority . . . Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120”). Where there is any ambiguity in the disclosures of the ’295 application, the absence of supporting testimony tends to cut against 26:2–31:2; see Ex. 1005 ¶¶ 12, 13, 18, 19, 16–21, 26, 28, claims 16–21, 26– 28. In view of the foregoing, we are not persuaded that Patent Owner has demonstrated that the inventors of the priority applications were in possession of a magnesium cast composite that included less than 50 wt. % magnesium, or greater than 50 wt. % additives. As proposed substitute claim 104 encompasses a magnesium cast composite with up to 90 wt. % additives, and therefore as little as 10 wt. % magnesium, Patent Owner has not demonstrated that the full scope of this claim finds written description support in any application prior to the ’915 application, filed on October 12, 2018.” slip op. at 17

“The definiteness requirement of § 112(a) is satisfied when “a patent’s claims, viewed in light of the specification and prosecution history, inform those skilled in the art about the scope of the invention with reasonable clarity.” Nautilus, Inc. v. Biosig Instruments, Inc., 572 U.S. 898, 910 (2014); see 37 C.F.R. § 42.100(b) (changing the claim construction standard used to review a claim proposed in a motion to amend from the broadest reasonable construction to the “same construction standard that would be used to construe the claim in a civil action under 35 U.S.C. [§] 282(b)”). Proposed substitute claim 104 generically requires “in situ precipitate” and also a specific type of in situ precipitate: “in situ galvanically-active intermetallic precipitate.” Mot. Appendix A. Although this claim would have best been clarified by Patent Owner after seeking preliminary guidance on its Motion to Amend, upon review of the written description, claims, and figures of the ’740 patent, as well as Patent Owner’s clarification in its Reply to the Opposition, we agree with Patent Owner that one of ordinary skill in the art would have understood that the “in situ galvanically-active intermetallic precipitate” is merely a more complete description of the “in situ precipitate” mentioned earlier in the sentence. Mot. Reply 4. As such, we do not find that this part of proposed substitute claim renders claim 104 indefinite.” slip op. at 22

“develops new refrigerants for use as heat transfer fluids. Ex. 1002 ¶ 149. Such a person would have had a Ph.D. in Chemistry, Chemical Engineering, Mechanical Engineering, Material Science, or a related field or discipline and at least 3 to 5 years of experience, or alternatively an M.S. degree and 5 to 10 years of experience. Id. Patent Owner’s Declarant, Dr. Bivens, provides a similar description of the person of ordinary skill in the art, stating that such a person would have a B.S. degree in Chemical Engineering or Chemistry, and five years of work experience, or a Ph.D. or M.S. degree and 2–3 years of experience. Ex. 2001 ¶ 23. Based on these descriptions, we find that the parties’ definitions of ordinary skill in the art are substantially the same, and agree with the parties that an ordinarily skilled artisan would be educated in the Chemical and Chemical Engineering arts or related disciplines. We also agree with the parties that a person having less formal education, such as a B.S. or M.S. degree, would require more years of experience than a person with more formal education, such as a Ph.D., to qualify as an ordinarily skilled artisan. We also find that neither party states how any difference in the parties’ articulated levels of skill impacts this proceeding. Thus, our analysis would be the same regardless of any minor differences between the parties’ respective articulations. Finally, we note that the level of ordinary skill in the art is reflected by the prior art of record. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art itself can reflect the appropriate level of ordinary skill in the art).” slip op. at 20

“We agree with Petitioner that the ’525 application’s statement that the compounds are “adaptable for use” weighs against a finding of adequate written description. First, “adaptable for use” is vague, as Dr. Bivens acknowledges. See Ex. 1177, 151:15 (testifying that “adaptable for use can have a wide range of meaning”). Second, the ’525 application gives no direction on how a skilled artisan would need to adapt any particular composition for use in AAC, or even if any “adaptation” was necessary. We find that such a teaching is important in this case to show that the inventors had possession of the claimed invention, given our findings above that the art of AAC was unpredictable and that a heat-transfer composition for AAC required specific technical features that were unpredictable and unexpected. For completeness, we again reject Patent Owner’s argument that “[t]o show the inventors possessed claim 1 requires no more” than the statement in the written description that “‘the compositions of the present invention are believed to be adaptable . . . with or without system modification.’” PGR12 Resp. 27–28 (quoting Ex. 1001, 7:4–8). Regardless of the exact wording of claim 1, the inventors “still [had to have] describe[d] some way of performing the claimed methods.” Ariad, 598 F.3d at 1355. And here, with merely a passing reference to AAC, the ’525 application fails to provide any credible “technologic knowledge” to demonstrate to an ordinarily skilled artisan that Patent Owner “was in possession of the invention that is claimed.” Id.” slip op. at 43

RulingsFinal written decision- BurdenDecided for petitioner
“Turning now to obviousness, Petitioner identified disclosure within Kurgonov-262 and Chakrabarti which teaches or suggests the limitations of claim 1. Pet. 11–21. Furthermore, Petitioner identified multiple reasons that would have prompted the skilled artisan to combine the teachings of Kurganov-262 and Chakrabarti to arrive at the subject matter of claim 1. Id. at 21–22. Because Patent Owner focused its arguments solely on the issue of whether Kurganov-262 is prior art, Petitioner’s assertions regarding the substantive teachings of Kurganov-262 and Chakrabarti remain unrebutted on the complete record. PO Resp. 31–34; Sur-reply 1–3. Patent Owner likewise failed to substantively address Petitioner’s proffered reasons why the skilled artisan would have been motivated to combine these teachings. PO Resp. 31–34; Sur-reply 1–3. We have reviewed the disclosures of Kurganov-262 and Chakrabarti relied on by Petitioner, as well as the explanations provided by Mr. Lipoff, and are persuaded that the limitations of claim 1 are disclosed in the prior art. Pet. 11–21; Ex. 1002 ¶¶ 103–109; Ex. 1004; Ex. 1008. Petitioner also persuades us that the skilled artisan would have been motivated to apply Chakrabarti’s techniques for web crawling to Kurganov-262’s system, and would have had a reasonable expectation of successfully doing so, thus arriving at the subject matter of claim 1 of the ʼ084 patent. Pet. 21–23; Ex. 1002 ¶¶ 110–114. Therefore, Petitioner has shown, by a preponderance of the evidence, that the subject matter of claim 1 of the ʼ084 patent would have been obvious over the combined disclosures of Kurganov-262 and Chakrabarti.” slip op. at 24

“Petitioner describes a person having ordinary skill in the art as having “a Bachelor’s degree in electrical engineering, computer science or a related field, and at least two years of experience with voice interfaces and information processing. More education could substitute for less experience, and vice versa.” Pet. 5 (citing Ex. 1002 ¶¶ 41–47). Patent Owner does not contest Petitioner’s definition of the skilled artisan. See generally, PO Resp. Neither party argues that the outcome of this case would differ based on our adoption of any particular definition of one of ordinary skill in the art. Moreover, the level of ordinary skill in the art is also reflected by the references themselves. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (“[T]he absence of specific findings on the level of skill in the art does not give rise to reversible error ‘where the prior art itself reflects an appropriate level and a need for testimony is not shown.’”); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (finding that the Board of Patent Appeals and Interferences did not err in concluding that the level of ordinary skill in the art was best determined by the references of record).

- Expert testimonyPatent owner expert discountedDecided for patent owner
“Rather, on the complete record, Patent Owner makes inadequately supported assertions regarding what the skilled artisan “would understand” based on the ʼ084 patent’s disclosure. See PO Resp. 33–34. For example, Patent Owner asserts that “[a] POSITA would understand that” polling or pinging “describes a process where by existing and new devices and/or websites are discovered,” and that “‘polling’ includes asking for information from a website, including a listing of URLs or asking a website of a search engine to provide new website information.” Id. at 34 (citing Ex. 2059 ¶¶ 154–155). We reject this line of argument because we afford minimal weight to Patent Owner’s reliance on paragraphs 153–155 of Exhibit 2059. PO Resp. 33–34. These declaration paragraphs provide little detail beyond what is argued in the Patent Owner Response. See 37 C.F.R. § 42.65 (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”).” slip op. at 22

“We are persuaded by Petitioner’s arguments that sufficient written description support does not exist in the ʼ996 application for “limitation 1.i” which requires the computing device to be “configured to periodically search via the one or more networks to identify new web sites and to add the new web sites to the plurality of web sites.” Pet. 6–11. Thus, we determine that Kurganov-262 is available as prior art against the challenged claims. On the complete record, Patent Owner fails to direct us to specific disclosure within the ʼ996 application that evinces written description for limitation 1.i. Rather, Patent Owner’s citations to the ʼ084 patent fail to describe with adequate precision a computing device configured to periodically search the network(s) to identify new web sites and add such new web sites to the plurality of web sites that are accessed.
