      “As an initial matter, we acknowledge that the definition “to process so as to add or increase the proportion of a desirable ingredient” has two possible interpretations. In the first interpretation, “add or increase” shares the same object “the proportion of a desirable ingredient.” When the proportion of one ingredient goes higher, the proportion of at least another ingredient would necessarily go lower. Thus, the enrichment process under this interpretation results in a higher proportion of the desirable ingredient relative to other ingredients. Patent Owner adopts this interpretation. See PO Resp. 17 (“In the context of preparing a sequencing library, [Patent Owner] Tecan proposes that a nucleic acid sequence of interest is ‘enriched’ when the proportion of nucleic acid fragments containing the sequence of interest is increased relative to other nucleic acid fragments in the sample.”). According to Patent Owner, “amplifying the one or more oligonucleotide extension products . . . thereby enriching the nucleic acid sequence of interest, by generating amplified products comprising the enriched nucleic acid sequence of interest” in step (c) means “increas[ing] the proportion of the nucleic acid sequence of interest relative to the nucleic acid fragments in the solution not containing the sequence of interest by amplifying the oligonucleotide extension product and its complement.” Id. at 19–20. Under the second interpretation, the object for “add” is “a desirable ingredient,” whereas the object for “increase” is “the proportion of a desirable ingredient.” This interpretation is broader than the first one in that the result of the enrichment process not only encompasses a higher proportion of the desirable ingredient relative to other ingredients, but also more desirable ingredient in raw number.” slip op. at 11

      “We agree with Dr. Sims. As explained above, the amplification step must result in at least some enrichment of the sequence of interest, even though it does not have to be the only cause. See supra Section II.C.2.b. Indeed, Petitioner acknowledges that “at least some of the enrichment must result from the recited steps.” Reply 12. Because Meyer’s enrichment for mRNA using the SMART protocol occurred before any recited steps of claim 1, we find it does not meet the claimed “enrichment” under our construction.” slip op. at 22

      “to “enrich” means to “increase[] relative to the rest of the fragments.” Tr. 12:25–26. The panel asked: “In the starting material, there are three components, A, B, C, that say it’s 30 percent, 50 percent and 20 percent. You do PCR and it -- they all get amplified and the end result is still 30 percent, 50 percent, and 20 percent. Anything got enriched?” Id. at 12:18–21. Petitioner responded that “petitioner’s position is that in that situation, there is no enrichment.” Id. at 12:22–23. In other words, Petitioner does not disagree with Patent Owner that mere increase in the raw number is not enrichment. See also id. at 13:7–9 (“[W]e would agree that if it is truly unbiased amplification, that does not result in an increase in the proportion, and so that does not meet the plain meaning of enrich.”). We find the record, including the testimony from all three declarants, supports Patent Owner’s argument. See Sur-reply 1–5 (citing Ex. 1125, 283:1–6, 286:22–287:14; Ex. 1126, 170:18–171:1; Ex. 2037, 150:18–22, 173:15–17; Ex. 2038 ¶ 95), 8 (citing Ex. 1125, 271:10–15; Ex. 2037, 188:22–189:1).
