    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundInstituted

      “Petitioner argues that a person of ordinary skill in the art would have been motivated to look to the features of both Singh129 and Singh906 when considering an improved publishing system. Pet. 16. Further, Petitioner points out that Singh129 incorporates by reference the ’802 application, published as Singh906. Id. According to Petitioner, a person of ordinary skill in the art would have been motivated to modify Singh129’s system to add Singh906’s user authentication credentials to Singh129’s user preferences to give the “user more control over the publishing of their multimedia content.” Id. at 17 (citing Ex. 1030 ¶ 456). Petitioner cites four additional reasons for a person of ordinary skill in the art to modify Singh129 with Singh906 including solving a known problem, avoiding sending authentication credentials to publish content, virtual spaces provided for clients in Singh906, and that authentication credentials would have been an obvious design choice. Id. at 17–18 (citing Ex. 1009 ¶ 47, Figs. 2, 5; Ex. 1010 ¶¶ 17, 18, 27; Ex. 1030 ¶¶ 457–461). Petitioner also asserts a person of ordinary skill in the art would have had a reasonable expectation of success for the modification of Singh129 with Singh906. Pet. 18. Petitioner argues “the proposed combination would have required no more than the application of known techniques (using authentication credentials and HTTP in accordance with Singh906) to a known system (Singh129’s system) in the same field of endeavor (media publishing) and from the same assignee (CellSpinSoft) to obtain the benefits described above.” Id. (citing Ex. 1030 ¶ 461). Based on the record before us, we find sufficient the argument and evidence that the combination of Singh129 and Singh906 teaches or suggests all of the limitations of claim 1, and that a person of ordinary skill in the art would have had reason to combine features from Singh906 into Singh129 with a reasonable expectation of success, for the reasons discussed in the Petition. See Pet. 16–19. We have also reviewed Petitioner’s contentions with respect to dependent claims 2–15, and find the same for these claims. See id. at 28–38.” slip op. at 25

      “claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. 35 U.S.C. § 103; see also KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations including (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) when in evidence, objective evidence of nonobviousness.10 Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966). An obviousness determination requires finding a reason to combine accompanied by a reasonable expectation of achieving what is claimed in the challenged patent. See Intelligent Bio-Sys., Inc. v.

      “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.

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.”).

Tr. 65:21–66:9 (Petitioner’s counsel explaining that the droplets do not combine in the PCR thermal cycling tube but, rather, are “suspended in an immiscible fluid and analyzed en masse”). indicates that the first instance of single sample volume, i.e., the single sample volume in which the presence or absence of each M analytes are to be detected, is the antecedent basis for the second instance of “single sample volume,” i.e., the single sample volume in which the analytes are amplified. Thus, as the parties appear to agree, the single sample volume in which amplification takes places must be the same single sample volume in which the presence or absence of analytes are to be detected.

Nor does Petitioner respond to our inquiry about whether collateral estoppel maybe applied on a limitation by limitation basis. See Pet. Reply 27. At the hearing, however, Petitioner confirmed that resolution of the issue is not necessary to our final determination. JUDGE ROSS: Do we even need to decide the collateral estoppel issue? I mean, it seems to me that if your petition clearly made out your case for the combination of Richardson and Zhao, then we don't even need to reach that. MR. CHANDRA: That’s exactly right, Your Honor. That is our position, as well. We believe collateral estoppel applies, but you don't need to decide that issue in order to find these claims unpatentable. As I mentioned before, these are the same references. We have fairly sought out all of the portions of Richardson, we cited to specific portions. Not just relying on collateral estoppel, but the teachings of the reference itself. So, while this is an issue, we believe that collateral estoppel should apply. It does not have to apply in order to find the challenged claims unpatentable. Tr. 19:9–20.

      “We do not agree with Petitioner that the fact pattern before us is analogous to Rembrandt. The rationale to combine the teachings of Inoue and Smith provided in the Petition focuses on replacing incandescent bulbs with LEDs, and includes the generic statement that “[t]he numerous record-supported advantages, set forth in Smith provide a clear motivation for use of the teachings of Smith as applied to Inoue, so as to enjoy the advantages set forth in Smith.” Pet. 47. The testimony in Dr. Schubert’s Declaration at pages 99–100 cited in support of Petitioner’s Reply arguments was not cited or otherwise referenced in the Petition. See Pet. 46–55. We find that the Petitioner’s Reply is not responsive to the Institution Decision and is improper because it presents a new rationale to combine the teachings of Inoue and Smith that was not expressed in the Petition. See 37 C.F.R. § 42.23; CTPG § II.I. Petitioner could have presented its rationale to make out a prima facie case of unpatentability in the Petition. See 37 C.F.R. § 42.23; CTPG § II.I. Accordingly, we do not consider Petitioner’s new rationale to combine the teachings of Inoue and Smith presented for the first time in the Reply. Based on the entire record, but not including Petitioner’s new rationale and newly cited support to Smith and Dr. Schubert’s testimony (Exs. 1013, 1017) presented for the first time in the Reply, we are not persuaded that Petitioner sets forth in the Petition sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to one of ordinary skill in the art to modify the circuit of Inoue to include a light source or LED light source with a twinkling or flashing effect in view of Smith’s teachings. See Pet. 46–47, 49–50, 51–53, 55.

      “We observe that, aside from Declaration testimony of Mr. Altamura and accompanying exhibits, Patent Owner does not offer any additional evidence to establish reduction to practice. An inventor’s testimonial assertion of inventive facts requires corroboration by independent evidence. Brown v. Barbacid, 276 F.3d 1327, 1335 (Fed. Cir. 2002). The purpose of the corroboration requirement is to prevent fraud, by providing independent confirmation of the inventor’s testimony. Kridl v. McCormick, 105 F.3d 1446, 1450 (Fed. Cir. 1997). Without the requirement of independent corroboration, there would be a great temptation to commit perjury and the adverse party would be effectively precluded from a successful rebuttal. Price v. Symsek, 988 F.2d 1187, 1194–95 (Fed. Cir. 1993). A rule of reason applies to determining whether the inventor’s testimony has been corroborated. See id. at 1195. “The rule of reason, however, does not dispense with the requirement for some evidence of independent corroboration.” Coleman v. Dines, 754 F.2d 353, 360 (Fed. Cir. 1985). Accordingly, based on the entire record, we find that Mr. Altamura’s Declaration testimony is uncorroborated.
