“institute trial in an inter partes review. We institute an inter partes review only if the information presented in the petition filed under 35 U.S.C. § 311, and any preliminary response filed under § 313, shows that there is a reasonable likelihood that Petitioner would prevail with respect to at least one of the claims challenged in the petition. 35 U.S.C. § 314. After reviewing the parties’ submissions in view of the existing record, we conclude that Petitioner demonstrates a reasonable likelihood it would prevail in showing that at least one challenged claim of the ’992 patent is unpatentable under the presented grounds.

- 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.

“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

“For a claim to a biological material, the enablement requirement of § 112, first paragraph, does not require such assured access to a microorganism deposit as of the filing date; what is required is assurance of access (to the microorganism culture by the public upon issuance of a patent on the application) prior to or during the pendency of the application, so that, upon issuance of a U.

Patent Owner has persuaded us that such exception not only applies to a deposit, but also extends to a biological material known and readily available. See 52 Fed. Reg. 34080, 34081.

We agree with Patent Owner that the Petition fails to demonstrate that Kahn discloses or teaches these limitations because the evidence does not provide support that there is remote control of fluid handling devices or the use of a user command on a control interface to send a command to a fluid handling device, for instance. Kahn is directed to providing access to fluid sensing data and analyzing and providing visual information on that data, but we do not discern that it teaches or discloses the capability to remotely control fluid handling devices. See, e.g., Ex. 1005, code (54), 1:27–36, 2:50–3:2. More specifically, the Kahn disclosures that Petitioner repeatedly relies upon for allegedly teaching this control are deficient. See Ex. 1005, 10:62–67, 14:35– 15:2, 15:62–16:32; see also Pet. 12–14, 16–18.

Communication unit 112B is part of the local “sensor unit,” wherein the detection conditions determined by the sensor are communicated to remote devices by communication unit 112B. See id. at 3:31–33, 5:62–6:2, 6:27–35, 7:33–37, 13:7–12, Figs. 1A–1C. Kahn discloses that the sensor units, which include communication units 112B, can be located near shut-off valves and can communicate with distant locations. See id. at 11:1–13. There are no disclosures, however, in the above passages that there is remote control of fluid handling devices, that there is a user command on a control interface that actuates an actuator, or that there is a command sent to the facility actuators via a network connection, as required in limitations [18.5]–[18.7] and [18.9]–[18.12], respectively.

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

“We find the District Court’s reasoning persuasive, and we, like the District Court, decline to adopt Petitioner’s overly broad proposed construction. However, for purposes of deciding the dispositive fact issue before us, we need not determine the precise boundaries of “surrounding textile structure,” for example whether it completely or mostly encircles the textile element, and if “mostly,” what percentage of encircling is required. See Pet. Reply 2 (Petitioner characterizing Patent Owner’s position as “mostly” means over 50%); id. at 4 (Petitioner impliedly arguing that the “surrounding” need not be complete, i.e., 100%); PO Sur-reply 3–4 (Patent Owner arguing that “Zuckerman’s textile structures . . . each abut only about 25% of the periphery of Zuckerman’s blank.”). We find that a person of ordinary skill in the art would not understand the portion of Zuckerman’s strip 13 in purple to surround the green blank 11 (textile element) under any reasonable construction of “surrounding textile structure.” Dr. Pastore testifies that “Zuckerman discloses two separate textile structures adjacent the blank—one on each side . . . they abut only two sides of Zuckerman’s blank, with each structure abutting only about a quarter of the blank’s periphery,” and opines that “a POSITA would not have understood these two separate structures, designated by purple in the figure above, to be a textile structure ‘surrounding’ the blank [shown in green].” Ex. 2003 ¶ 54. We find Dr. Pastore’s tesimony credible as it is consistent with Zuckerman’s Figure and with the plain and ordinary meaning of “surrounding” and with the Specification of the ’749 patent (particularly Figure 9). Dr. Brookstein’s testimony, on the other hand, is based on Petitioner’s overly broad proposed construction—that any part of a textile area that is not a textile element is “surrounding textile structure”—” slip op. at 44

“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.”).

“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.

“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).
