“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

“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).

RulingsFinal written decision- Skill levelSkill level petitioner adoptedDecided for petitioner
“Patent Owner’s proposed POSA level is too broad. Under that proposal, an individual with, for example, an undergraduate degree in microbiology and three years’ work experience studying the habitats of bacteria might qualify as a POSA. It is not clear that such person would have sufficient, relevant experience in the detection of chromosomal abnormalities, especially through non-invasive methods for detecting fetal genetic abnormalities in maternal samples, as described in the ’277 patent and the prior art here. See, e.g., Ex. 1001, 1:31–5:59 (Field of Invention and Background Art); Ex. 1003 (Chiu). Petitioner’s proposal of the POSA level is more precise because it requires familiarity with techniques for detecting cell-free DNA in biological samples, which is relevant to the prior art and the claimed technology. Petitioner’s proposal also appears to be more consistent with the cited prior art. Okajima v. Bourdeau, 261 F.3d 1350, 14 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required where the prior art itself reflects an appropriate level and a need for testimony is not shown). Accordingly, we adopt Petitioner’s POSA level here, but note that our other determinations on this record would not change under Patent Owner’s POSA level.13” slip op. at 14

“n.3; PO Sur-Reply 14–15; see generally Papers 51 and 52.14 It is not necessary for us to further construe those dependent claims to resolve this case. Petitioner relies on formaldehyde or formaldehyde donors, as disclosed in Bianchi, Granger, and Rao, to satisfy the claimed “agent” term, and urges the addition of such compounds to Chiu’s method for isolating and detecting cffDNA in a maternal sample. There is no dispute on this record that formaldehyde and formaldehyde donors meet the claimed “agent” term. We are, thus, able to determine if the asserted art discloses an “agent” as claimed and whether a POSA would have been motivated to add formaldehyde or a formaldehyde donor to Chiu, which issue we find is decisive here, without further interpreting dependent claims 90, 91, or 133. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co. Ltd., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“[W]e need only construe terms that are in controversy, and only to the extent necessary to resolve the controversy.”) (internal quotation marks omitted). 14 The disagreement on interpretation of this handful of dependent claims arose in relation to Rao’s prior-art status for those claims (Pet. Reply 5 n.3; PO Sur-Reply 14–15), and Patent Owner’s nexus showing for secondary considerations of nonobviousness (id. at 21). See Pet. Reply 3 n.2 (noting the priority “arguments are only relevant to Ground 3” because the prior art status of Chiu, Bianchi, or Granger is uncontested). But, as we discuss below, Petitioner’s challenge to the claims fails on this record regardless of the disagreement on Rao’s prior art status and, because Petitioner has not made the necessary threshold showing that a POSA would have combined the asserted art in the manner proposed, we need not reach secondary considerations of nonobviousness.” slip op. at 16

“detection method of Chiu.27 More specifically, we find on this record that a POSA would have been dissuaded from adding Bianchi’s paraformaldehyde because the POSA would have expected Bianchi’s paraformaldehyde to create gaps in the cell membranes, providing a means for maternal DNA to escape into the sample. We also find on this record that a POSA would have been dissuaded from adding paraformaldehyde to Chiu’s methods because formaldehyde was known to damage nucleic acids.28 Patent Owner’s reasoning and evidence on those issues, separately and cumulatively, outweigh Petitioner’s comparatively weak showing on whether a POSA would have combined the art in the manner proposed. We discuss in greater detail below. We begin with the issue that paraformaldehyde contributes to permeabilization of the cellular membrane. We credit Dr. Van Ness’s opinion that adopting Bianchi’s approach to treating cells with paraformaldehyde creates a means for cellular DNA to escape. Ex. 2078 27 WBIP, LLC v.

Cir. 2006) (“The presence or absence of a motivation to combine references in an obviousness determination is a pure question of fact”). 28 When asked whether he considered “any differences between paraformaldehyde and formaldehyde that might be relevant to DNA damage in forming your opinions,” Dr. Edwards testified “[t]here should be no differences” and that “[i]n this field, these terms are often used interchangeably.” Ex. 2299, 69:3–20. We find, therefore, that the issues, including DNA damage, with formaldehyde would have been understood to also apply to paraformaldehyde on this record. 38 ¶¶ 96–98; Ex. 2101, 106:4–19 (testimony of Dr. Edwards agreeing that “DNA is one thing that can escape a cell when you permeabilize it”). Although Bianchi discloses a desire to keep “substantially all” of the target molecules inside the cells, by Bianchi’s own definition, “substantially all” includes leakage of up to 50% of the target molecules and cellular DNA. Ex. 1004, 1:42–49; Ex. 2078 ¶¶ 99–101. We find that increasing potential leakage of DNA from the maternal cells runs counter to Chiu’s objectives.

“fingerprint must “vaporize” from the coated surface.30 As discussed above (Section III(C)), the claimed “anti-fingerprint” functionality encompasses a coating that is capable of actively reducing transfer of a fingerprint or decomposing a fingerprint transferred to a surface of the coated substrate. Accordingly, notwithstanding Buchanan’s shortcomings in evidencing inherent vaporization of enzymatically decomposed fingerprint components, we are unpersuaded this is fatal to Petitioner’s challenge. Rather, for” slip op. at 43

“conclusory” lack merit. Dr. Cairns has relevant expertise in this area, whereas Petitioner’s declarant, Dr. Rozzell, does not. Ex. 2035 (Rozzell dep.), 128:15–20 (“[Y]ou are not a person of ordinary skill in the art as it pertains to the use of haze values to assess visibility, are you? A. No.”); Ex. 2033 (Cairns Decl.) ¶¶ 2–9 (describing, inter alia, Dr. Cairns’s many years of experience working with and researching specialized coatings for display and touch-sensor applications and optical properties for such devices). Accordingly, Dr. Cairns’s testimony about there being a recognized and sufficiently definite correlation between haze and contaminant (including fingerprint) visibility on display devices is entitled to greater weight than Dr. Rozzell’s opinions on the topic. See, e.g., Ex. 2036 ¶¶ 62–67 (analyzing portions of the patent and prior art to support the opinion that haze is correlated to visibility); Ex. 2035 (Rozzell dep.) 125:1– 16 (“[W]hatever familiarity you have acquired with respect to the utilization of haze as a measurement of visibility has been acquired in the context of this IPR; correct? A That’s correct.”). Dr. Cairns’s opinions are also not conclusory as argued, but are supported with evidence from the patent and the prior art as noted. Ex. 2036 ¶¶ 62–67. slip op. at 83

“have wanted to combine Amin’s and Wang’s coatings, Petitioner simply does not provide an adequate, evidence-backed analysis of how such person would have predictably done so. As Patent Owner points out, the evidence on this record raises doubts that the two coatings could have been successfully combined. MTA Reply 6–8. Specifically, evidence of record supports Patent Owner’s argument that a skilled artisan would not have reasonably expected “that the digestive enzymes of Wang could be successfully immobilized on the fluorine-coated surface of Amin.” Id.; Ex. 2036, ¶¶ 6–10; Ex. 2035, 15:5˗19:2. Notably, the testimony of Petitioner’s own declarant supports the conclusion that the combination Petitioner proposes would not have been reasonably predictable—if even possible at all. When Dr. Rozzell was asked if there were other materials (like enzymes) that could be adhered to the surface of Amin’s coatings, he did not know. Ex. 2035: 15:16–17:13 (“[Y]ou don’t know what any of those materials [that might adhere] are, sitting here today? A Not without doing some research on my end.”) (“So turning back to our discussion of immobilizing an enzyme on this [Amin’s coating], you don’t know of a way, today, that you could immobilize an enzyme on top of a fluorine-coated layer. A Well, I’ve personally not done exactly that type of experiment, but I can imagine that there would be approaches that would allow you to do that. Q But you don’t know any of them today? A I can’t tell you one as I’m sitting here today. Q Okay. And you’ve not recalled seeing this in a publication? A No.”).” slip op. at 87
