See, e.g., Ex. 1007, code (57). Petitioner additionally argues that there is a reasonable expectation of success in combining Cable with Naware because “3D printers with temperature-controlled heated build plates were well-known technologies at the time of the ’660 patent in 2014, and these technologies had been successfully demonstrated in the real-world by then.” Pet 15 (citing various portions of Ex. 1003).

And, although there are no bright-line rules for the amount of disclosure needed in an unpredictable art, that amount “necessarily changes with each invention” and “changes with progress in the field.” Ariad, 598 F.3d at 1351. Here, we find that the art of AAC was unpredictable and that a heat-transfer composition for AAC required specific technical features that were unpredictable and unexpected. Thus, we conclude that the ’525 application requires a more-detailed disclosure than would be required in a predictable field to adequately demonstrate possession of a heat-transfer composition consisting essentially of HFO-1234yf and PAG for use in AAC. (iii) Disclosure in the ’525 Application With these background findings in mind, we now turn to the four corners of the ’525 application—and we find that the ’525 application does not contain the detailed disclosure needed in this case to reasonably convey possession of a heat-transfer composition consisting essentially of HFO- 1234yf and PAG for use in AAC.” slip op. at 37

Thus, we find that Patent Owner does not contest that a heat-transfer composition consisting essentially of HFO- 1234yf and PAG for AAC was in public commercial use before the March 26, 2014, filing date of the ’017 patent. Accordingly, we find that Petitioner’s evidence, together with Patent Owner’s concessions, demonstrates by a preponderance of evidence that the claimed subject matter of the ’017 patent was in commercial use before its March 26, 2014, effective filing date.

Id. at 2–3. Petitioner and Dr. Brown direct us to the Sevice Guide’s entries calculations, which show that the Ford Transit Custom Bus had an AAC refrigerant-lubricant composition of 26.7% of PAG lubricant and 73.3% of HFO-1234yf (Ex. 1002 ¶ 401 (citing Ex. 1013, 38)); the Mazda CX 5 2.0i had 16.7% PAG lubricant and 83.3% HFO-1234yf (Ex. 1002 ¶ 402 (citing Ex. 1013, 55)); the Mazda CX 5 2.2D had a 17.5% PAG lubricant and 82.5% HFO-1234yf (id.); and the Opal Mocca had 11.6% PAG lubricant and 88.4% HFO-1234yf (Ex. 1002 ¶ 402 (citing Ex. 1013, 70)). As to dependent claims 2, 11, and 14, which all require that the lubricant is present “in an amount from about 30% to about 50% weight,” we credit Dr. Brown’s uncontested testimony that the refrigerant-lubricant composition of the Ford Transit Custom Bus recited lubricant amount. Ex. 1002 ¶ 403. In particular, we agree with Dr. Brown that, because the lubricant accounts for 26.7% of the AAC refrigerant-lubricant composition in the Ford Transit Custom Bus, the lubricant makes up “about 30%” of the refrigerant-lubricant composition as claimed.

“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).

For purposes of this Decision, we adopt Petitioner’s proposed level of ordinary skill as it appears to be consistent with the level of skill reflected by the specification and in the asserted prior art references. See 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 14

“construe claim terms “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b).” 37 C.F.R. § 42.100(b) (2019). The parties stipulated to constructions of “reservoir” and “chamber” in the district-court litigation. Ex. 1005, 2. Petitioner proposes additional constructions for “impeller” and “radiator.” Pet. 8–10. Patent Owner does not dispute those constructions. See generally Prelim. Resp. Based on our analysis of the issues in dispute at this stage of the proceeding, we conclude that none of the claim terms identified by the parties require express construction at this time.

“The burden of showing a decision should be modified lies with the party challenging the decision. The request must specifically identify all matters the party believes the Board misapprehended or overlooked, and the place where each matter was previously addressed in a motion, an opposition, or a reply. Thus, a request for rehearing is not an opportunity to present new arguments or evidence or merely to disagree with the panel’s assessment of the arguments or weighing of the evidence.” slip op. at 3

“legally required for Salesforce to be a “beneficiary.” Req. Reh’g. 14. Further, Petitioner further asserts that we overlooked the authority cited by Petitioner that “‘behest’ means command, and that RPX cannot have acted as Salesforce’s representative unless RPX were appointed by Salesforce to so act.” Id. at 14–15. Petitioner asserts that the evidence, at most, demonstrates that RPX filed as a “mere volunteer to benefit Salesforce.” Id. at 15. We are not persuaded because Petitioner’s argument proposes that we apply a more narrow and rigid analysis of RPI than the one instructed by the Federal Circuit in these cases. As stated by the Federal Circuit, “[d]etermining whether a non-party is a ‘real party in interest’ demands a flexible approach that takes into account both equitable and practical considerations, with an eye toward determining whether the non-party is a clear beneficiary that has a preexisting, established relationship with the petitioner.” AIT, 897 F.3d at 1351; see also Dec. 4–5.
