      “Based on the current record and for the reasons explained below, we institute an inter partes review of claims 1–15 of the ’766 patent on all challenges in the Petition. Upon consideration of the Petition and the evidence of record, for the reasons given below we determine there is a reasonable likelihood that Petitioner would prevail in establishing the unpatentability of at least one challenged claim of the ’766 patent. Accordingly, we institute an inter partes review of claims 1–15 of the ’766 patent based upon the asserted grounds of unpatentability set forth in the Petition. Pet. 1.” slip op. at 2

    • 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

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “These two proposed definitions of the ordinarily skilled artisan share many consistencies, for example, the types of degrees and experience such a person would have had, but differ in the number of years of experience. Petitioner proposes the ordinarily skilled artisan would have had at least five years of experience and Patent Owner proposes at least three years (which would necessarily include five years, too). Patent Owner also proposes that the ordinarily skilled artisan would have consulted a dentist, oral surgeon, prosthodontist, or periodontist with experience in dental implants and prosthetics. At this point, we find little meaningful difference between the two proposed definitions. In fact, neither does Patent Owner’s witness, Mr. Leinsing, who states that his “opinions would not change under either definition.” Ex. 2011 ¶ 40. Thus, at this stage, we accept and use Petitioner’s proposed definition of the ordinarily skilled artisan, which, unlike Patent Owner’s, does not implicate reliance on the knowledge of people other than the individual ordinarily skilled artisan. Petitioner’s definition appears to comport with the level of skill in the art reflected in the prior art of record and the ’992 patent. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (“the prior art itself [may] reflect[] an appropriate level” of the ordinary level of skill in the art) (quoting Litton Indus. Prods., Inc. v. Solid State Sys.

    • Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateNot entitled to earlier dateDecided for petitioner

      “Here, the first claim limitation at issue is broad, i.e., different thread pattern/profile between a definite and a temporary screw, and the Specification’s and priority applications’ disclosure is narrow and specific, asymmetric buttress style threads in a temporary screw and symmetrical threads in a definite screw (are different). Any apparent predictability in or maturity of the relevant field here must be contrasted with the fact that the Specification, considering the ’992 patent itself or any of the identified priority applications, never once even discusses the (claimed) concept of specifically differing the thread style between a temporary and a definitive screw. Any differences in thread style are not called out by the disclosure, but are described and can be discerned only in relation to the respective threads’ functionality, i.e., Fig. 75’s temporary screw 190 has buttress-style threading so it can be pulled out rather than unscrewed from the abutment; Fig. 9’s definitive screw 75 has male threads that fill the female threads of the abutment 8 for a secure permanent engagement. Ex. 1001, 15:23–30, 21:25–44, 23:3–36; Ex. 1012, 97–98, Figs. 9, 75. And, although it is possible for a single disclosed species to provide written description support for a claimed genus, “a sufficient description of a genus . . . requires the disclosure of either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can ‘visualize or recognize’ the members of the genus.” Ariad, 598 F.3d at 1350; see also Synthes USA, LLC v. Spinal Kinetics, Inc., 734 F.3d 1332, 1344 (Fed. Cir. 2013). That does not appear to be the case here—the present record does not support that the described asymmetrical buttress, serrated style of different temporary screw threading (relative to that of the definitive screw and regardless of the direction of the threads for rotation) is sufficiently representative of the genus’s “different” thread patterns/profiles. See, e.g., Ex. 1006 (a buttress style thread does not function the same as a buttress reverse or 75º joint profile or rounded, or trapezoidal thread).” slip op. at 30

We likewise note Dr. Jain’s testimony that such artisan would have recognized Tokunaga’s conclusion, regarding “immunological and biochemical properties” of Factor C proteins of the two different horseshoe crab species, to be “based on only gross biophysical-biochemical properties” that are not “granular enough” to predict functional properties such as residual activity in presence of specific ions.

Nevertheless, as discussed above, Petitioner has provided contrary evidence, including statements from Patent Owner’s patent application, suggesting that, “due to the various differences and diversity of biomolecules depending on the genus and species of the horseshoe crab,” it had not been possible “to accurately determine the full-length sequence structure, expression, and function of [Limulus] proteins and genes using conventional methods” more than 20 years after complete gene and amino sequences from two Tachypleus horseshoe crab species had been reported. Pet. 35 (citing, e.g., Ex. 1005 ¶¶ 12–17). Thus, even if we were to take the Frohman Declaration into account, we find that Petitioner has established a reasonable likelihood 28 of success that the ’767 application disclosures did not enable an ordinarily skilled artisan to make and use the invention of the challenged claim without undue experimentation. Furthermore, assuming that the disclosures in ’767 application would have enabled an ordinarily skilled artisan to express recombinant Limulus polyphemus Factor C protein in HEK293, we find Petitioner has established, sufficient for purposes of institution, that the disclosures do not enable an ordinarily skilled artisan to make such a protein exhibiting the “full scope” of the claimed residual activity, without undue experimentation. Patent Owner cites to disclosures in the ’767 application that (1) describe how to produce recombinant Factor C in HEK293 cells and measure residual activity, (2) suggest “Factor C expressed in mammalian cells can have low susceptibility to activity inhibition by ions,” and (3) provide examples where residual activity met the required minimum. Prelim. Resp. 26–27, 32–34. Nevertheless, whether an ordinarily skilled artisan would have been able to make, based on these disclosures and without undue experimentation, a recombinant Factor C protein having residual activity encompassed by claim 21 but higher — even significantly higher — than that achieved in the example, is a fact intensive issue that would benefit from further development during trial.15 See, e.g., In re” slip op. at 28

      “Considering the arguments and evidence currently of record, we determine the Petition demonstrates “a reasonable likelihood that [P]etitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a).

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “At this stage, we find Petitioner’s description of the level of ordinary skill in the art to be sufficient. According to the ’360 patent, “[t]he field of the invention is related to sensor arrays for the detection and diagnosis of disease states.” Ex. 1001, 1:28–29. The Specification describes accomplishing such by analysis of protein coronas using techniques such as LC-MS/MS. See id. at 4:43–5:2 (describing Figure 1). The prior art cited by Petitioner also describes the analysis of protein coronas using similar analytical techniques. See, e.g., Ex. 1005, 584; Ex. 1007, 1870; Ex. 1008, 355–356. Accordingly, the present record supports that a POSA would have an understanding of both proteins and the analytical techniques, e.g., mass spectrometry, that can be used to characterize them. We understand Petitioner’s definition of a POSA to encompass these elements. It requires a formal degree in chemistry,5 which itself entails some knowledge of proteins and related analytical techniques, along with several years’ additional experience in proteomics, protein analysis, or mass spectrometry. Moreover, Petitioner’s definition is flexible in that it allows higher education or skill with, e.g., mass spectrometry, to make up for a lack of specific experience with proteomics assay and protein coronas. This explanation is reasonable and supported on the current record.” slip op. at 8

      “Third, and perhaps most importantly, there is “no requirement for perfect match between an expert’s experience and the relevant field.” See Consolidated Trial Practice Guide (Nov. 2019) 34, available at https://www.uspto.gov/sites/default/files/documents/tpgnov.pdf (“CTPG”). (citing SEB S.A. v. Montgomery Ward & Co., 594 F.3d 1360, 1373 (Fed. Cir. 2010)). A person need not be a person of ordinary skill in the art to testify as an expert under Federal Rule of Evidence 702, but rather must be “qualified in the pertinent art.” Sundance, Inc. v. DeMonte Fabricating Ltd., 550 F.3d 1356, 1363–64 (Fed. Cir. 2008). Here, there is no dispute that Dr. Vargas is qualified in the art of mass spectrometry and, on the current record, we discern no reason why she is not qualified to offer the testimony in her declaration. At most, Patent Owner’s argument that Dr. Vargas lacks experience “perform[ing] mass spectrometry techniques specifically for protein analysis,” goes to the weight we should afford her testimony at trial. See Prelim. Resp. 28–29. It is not a sufficient reason to deny institution, particularly given that Dr. Vargas’s testimony is only part of the showing offered in support of the Petition. 6 Patent Owner’s narrow characterization of Dr. Vargas’s experience (see Prelim. Resp. 28–29) is arguably inconsistent with the description in her CV (Ex. 1004). In any event, Patent Owner will have an opportunity to examine Dr. Vargas regarding her qualifications.” slip op. at 10

      “3. Conclusion Regarding Claim 1 Petitioner has demonstrated a reasonable likelihood of prevailing on its challenge to claim 1 as unpatentable under 35 U.S.C. § 102 as anticipated by Zwinkels. D. Remaining Claims of Ground 1 and Grounds 2 and 3 The threshold for institution is a reasonable likelihood of Petitioner prevailing as to any single claim. 35 U.S.C. § 314(a). “Once that single claim threshold is satisfied, it doesn’t matter whether the [P]etitioner is likely to prevail on any additional claims.” SAS Institute, Inc. v. Iancu, 138 S. Ct. 1348, 1356 (2018). Thus, because we have decided to grant review of claim 1, we do the same for all claims challenged and all grounds raised. Id.; see also 37 C.F.R. § 42.108(a) (“When instituting inter partes review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.”). III. CONCLUSION For the reasons discussed above, we are persuaded that Petitioner has demonstrated a reasonable likelihood of prevailing in establishing that at least one of the challenged claims is unpatentable.

      “to move forwardly and rearwardly relative to the frame. Pet. 33–38. For example, paragraph 20, as cited by Petitioner, discloses that the rollers “are movably suspended in the frame in vertical direction, wherein the suspension of said roll or rollers is arranged to convert relative horizontal movements of the roll or rollers into vertical movements thereby compensating and/or attenuating said horizontal movements by gravity.” Ex. 1004 ¶20 (cited at Pet. 34). Further, Zwinkels attributes the forward and rearward movement to the use of the bicycle by the person exercising on it. See Ex. 1004 ¶27 (describing the “horizontal movements induced by the accelerations and decelerations of the training cyclist”) (cited at Pet. 35). Petitioner also cites multiple figures that illustrate forward and rearward movement. Pet. 35–37 (reproducing Ex. 1004, Figs. 3, 5, and 6). There is a reasonable likelihood Zwinkels teaches “wherein the movable interconnection of the upper member with the lower member is configured to enable the upper member to move forwardly and rearwardly in the fore-aft direction relative to the lower member in response to fore-aft forces that are transferred to the upper member from the item of exercise equipment in response to use of the item of exercise equipment,” as recited in claim 1. e) “wherein the movable interconnection of the upper member with the lower member is further configured to provide upward and downward movement of the upper member relative to the support surface during movement of the upper member forwardly and rearwardly in the fore-aft direction relative to the lower member.” Petitioner argues that Zwinkels’s pendulum arms 6 enable the rollers to move upward and downward relative to the frame while the rollers are also moving forwardly and rearwardly relative to the frame. Pet. 39–42. For example, paragraph 24, as cited by Petitioner, discloses that the pendulum arms connecting the rollers at fixed pivoting points on the frame “provides an easy and effective solution for absorbing and attenuating horizontal movements by converting these horizontal movements to vertical movements.” Ex. 1004 ¶24 (cited at Pet. 39). Petitioner also reproduces Figures 5 and 6, which illustrate the displacement of rollers in both the vertical and horizontal directions. Pet. 40 (citing Ex. 1004, Figs. 5–6). Figure 5 is reproduced below. Figure 5, reproduced above, “shows the embodiment in which there are two rollers 4 for the bicycle back wheel.” Ex. 1004 ¶34. Figure 5 shows two configurations of the embodiment on left and right sides. Ex. 1004 ¶34, Fig. 5. The configuration “at the left of FIG. 5 shows the pendulum arms 6 in a resting position, whereas the [configuration] on the right shows the pendulum arms 6 after they have due to the connecting link 7 concertedly moved to the right due to a force FH, causing that the rollers 4 have moved vertically upwards.” Ex. 1004 ¶34. There is a reasonable likelihood Zwinkels teaches “wherein the movable interconnection of the upper member with the lower member is further configured to provide upward and downward movement of the upper member relative to the support surface during movement of the upper member forwardly and rearwardly in the fore-aft direction relative to the lower member,” as recited in claim 1. f) “wherein the upper member is oriented parallel to the support surface plane during movement of the upper member relative to the lower member in the fore-aft direction and during upward and downward movement of the upper member relative to the support surface” Petitioner argues that Zwinkels’s rollers are oriented parallel to the ground or floor at all times. Pet. 42–44. Petitioner argues that this is clearly shown in Figure 5, which we reproduced in the immediate section above. See Pet. 43 (citing and annotating Ex. 1004, Fig. 5). We agree. There is a reasonable likelihood Zwinkels teaches “wherein the upper member is oriented parallel to the support surface plane during movement of the upper member relative to the lower member in the fore-aft direction and during upward and downward movement of the upper member relative to the support surface,” as recited in claim 1. 3.

In addition, Patent Owner has not shown that TC1507 was “known and readily available to the public” as of the filing date of the 2004 application. Therefore, the 2004 application does not enable the challenged claims, and the challenged claims are not entitled to the 2004 priority date.

      “Thus, the critical issue is not, as Patent Owner asserts, whether “the same application can be simultaneously enabling and not enabling.” Id. at 32. It is whether TC1507 was “known and readily available” to the public at the relevant time. As explained above, for the priority determination, the relevant time is April 30, 2004, the filing date of the 2004 application. Patent Owner has not produced or pointed to any evidence to show TC1507 corn “readily available” to the public without restrictions as of the filing date of the 2004 application. On the other hand, for prior-art status determination, the relevant time is February 16, 2006, the publication date of Barbour. Petitioner has presented sufficient evidence, which Patent Owner does not challenge, to show that, by 2006, corn harvested from TC1507 plants was “commercially available following the 2003, 2004, and 2005 growing seasons” and “[s]uch corn was sold as a commodity—without any contractual restrictions” Pet. 52 (citing Ex. 1007 ¶ 134).
