But even with that combination, Dr. Dichtel states only that a “POSA would have expected there to be a decrease in the amount of 6,7- dimethoxy-quinoline-4-ol at the end of cabozantinib (L)-malate’s synthesis that was attributable to hydrolytic degradation of the 4- (nitrophenoxy)quinoline intermediate by avoiding its use in the synthesis.” Id. ¶ 78. That is not, however, the standard for inherency. It must be the necessary result, not a possible expected result. The Federal Circuit in Par explained that: Inherency, however, may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient. If, however, the disclosure is sufficient to show that the natural result flowing from the operation as taught would result in the performance of the questioned function, it seems to be well settled that the disclosure should be regarded as sufficient.” slip op. at 28

In order to distinguish Uniyal, the claims have been amended to recite a single static set of ultrasound RF data in a single frame of the tissue area.

“However, neither Petitioner nor Dr. Jansky provide specific data on the record before us showing the actual measured homozygosity of either of the inbred lines, US-W 5309 and US-W 5315. And Phumichai experimentally demonstrates that Dr. Jansky’s assumption that theoretical heterozygosity reduction of 50% per generation is not necessarily accurate, stating the “observed average percentage of reduction of heterozygosity per generation (38.4% or 38.5%) was lower than the theoretically expected value of 50%.” Ex. 1005, 982. Indeed, Phumichai disclosed that the “SOPH [Section-based observed percentage of heterozygosity] decreased steadily from the original 100% in 99H2–1 (S0) to the family means of 62.4% in 3H2 (S1), 37.9% in 3H3 (S2).” Id. at 981. That is, Phumichai experimentally shows that in an S2 generation of a potato line, the heterozygosity was 37.9%, resulting in homozygosity of about 62.1%, below the 75% theoretically expected and the 75% required by claim 1 of the ’841 patent. Therefore, the evidence of record does not show that the S2 generation of potato lines in Jong necessarily satisfies the homozygosity recitation in claim 1 of the ’841 patent, and so cannot establish on the record before us that Jong inherently teaches this limitation.” slip op. at 15

“Owner is telling. Petitioner does not refute Patent Owner’s evidence of objective indicia. On the current record, the objective indicia evidence is compelling. As to long felt need, Patent Owner cited evidence on record before the Examiner that showed a persistent need recognized by ordinarily skilled artisans. In re Gershon, 372 F.2d 535, 538 (CCPA 1967). For example, Dr. Huang states “This research is the breakthrough we have been waiting for since nearly a century . . . This is crucial for the potato breeding worldwide.” Ex. 2009, 687. There is no evidence that this long-felt need was satisfied by another before Appellant’s invention. See Newell Companies, Inc. v. Kenney Mfg. Co., 864 F.2d 757, 768 (Fed. Cir. 1988) (“[O]nce another supplied the key element, there was no long-felt need or, indeed, a problem to be solved . . . .”). Lastly, Dr. Lindhout explains that this invention satisfies the long-felt need, stating “I have discovered, and disclosed in the present application for patent, how a fertile homozygote in” slip op. at 33
