“III. LEVEL OF ORDINARY SKILL IN THE ART Petitioner contends a person of ordinary skill in the art (“POSITA”) would have a Ph.D. degree in biological, chemical or biochemical engineering, molecular biology, or biochemistry and at least two years of experience in the field of utilizing or assessing horseshoe crab zymogen proteins (lysate, purified native and/or recombinantly produced) for endotoxin detection and quantitation. More education could substitute for experience to a certain extent, and vice versa. Pet. 22 (citing Ex. 1003 ¶¶48–49). Patent Owner does not dispute Petitioner’s description of a POSITA in its Preliminary Response. Prelim. Resp. 10. 1 In addition to other changes to Title 35, the AIA introduced amendments to 35 U.S.C. § 102. Because Patent Owner concedes that the ’725 application “contains, or contained at any time, a claim to a claimed invention that has an effective filing date on or after March 16, 2013” (Ex. 1022), the AIA version of § 102 applies to the ’109 patent.

“To show that the claims of the ’109 patent are unpatentable for lack of written description, Petitioner would have needed to show that the specification as filed (i.e., the ’420 application) fails to reasonably convey to those skilled in the art that Patent Owner had possession of the claimed subject matter as of the July 3, 2023, filing date. Petitioner did not. Pet. 23– 24. Nor does Petitioner’s declarant offer testimony that could support such a showing. See Ex. 1003 ¶50 (“I have been asked to provide my opinions as to the state of the art in this field for purposes of determining what the inventors disclosed as their invention as of December 10, 2013.”), ¶51 (“Whenever I offer an opinion in this declaration about the knowledge of a POSA, the manner in which a POSA would have understood the claims of the ’109 patent or its description, the manner in which a POSA would have understood the prior art, or what a POSA would have been led to do based on the prior art, I am referencing the December 10, 2013 timeframe.”). Although the ’420 application is essentially identical to the ’767 application, the person of ordinary skill in 2013 is not the same as in 2023. See Ariad, 598 F.3d at 1351 (“[T]he [written description] test requires an objective inquiry into the four corners of the specification from the perspective of a person of ordinary skill in the art.” (emphasis added)).

“Nevertheless, we determine that the contrary evidence Petitioner has cited suffices to establish a reasonable likelihood of success at this preliminary stage of the proceeding. In this regard, we also note Dr. Jain’s testimony — currently unrebutted — that an ordinarily skilled artisan would have known, based on Tokunaga’s sequence comparisons of Factor C proteins, that “certain sequence differences between [Limulus polyphemus] and Tachypleus tridentatus were non-conservative (i.e., potentially giving rise to changes in function in terms of enzymatic activity of Factor C).” Ex. 1002 ¶ 94 (citing Ex. 1022, 157). 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.

Evid. 801(c) (defining hearsay as a statement, not made at the current trial or hearing, “offer[ed] in evidence to prove the truth of the matter asserted”), with Fed. R.

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

“On this preliminary record, we agree with Patent Owner that Petitioner’s asserted level of ordinary skill in the art is higher than warranted when Petitioner argues that a person of ordinary skill “further would have had specific experience with implementing and designing library preparation methods.” Pet. 21–22. However, we disagree with Patent Owner that a POSA only need to “have had experience with DNA sequencing methods” (Prelim. Resp. 8) because an artisan with experience with only pre-NGS sequencing methods would not qualify as a person of ordinary skill. Instead, for purposes of this Decision, we find a person of ordinary skill would have had a Ph.D. in the field of chemistry, molecular biology, or biochemistry. Alternatively, a POSA would have had a B.S. or M.S. degree with three to five years of experience working in any of those fields. The person of ordinary skill would have had experience with NGS sequencing methods and a working knowledge of how those methods functioned. This definition of a person of ordinary skill is consistent with the skill level reflected in the disclosures of the ’357 patent and prior art.

Our Trial Practice Guide cautions against crediting such unsupported testimony: The Board has broad discretion to assign weight to be accorded expert testimony. Yorkey v. Diab, 601 F.3d 1279, 1284 (Fed. Cir. 2010). However, the testimony must be based on sufficient facts and data. Fed. R.

“requirement.” Pet. Reply 5. We do not agree with Petitioner. We find that the language of the claims supports Patent Owner’s argument that the desired signal and the interferer signal are received together. As discussed infra, claim limitations 7.7 and 7.8 recite determining a signal strength of the interferer signal and determining a signal strength of the desired signal. These determinations must be performed at the same time; otherwise, the determinations of signal strengths would not be of the same wireless signal. See Larson II Decl. ¶ 70; Baker II Decl. ¶¶ 48–49 (explaining that consideration of signal strengths detected at the same time would be “essential”). The specification of the ’202 patent further supports this finding: “When a receiver is actively receiving a desired signal, each block in the signal path has at its input the desired signal as well as noise and possibly interfering signals.” Ex. 1001, 5:22–24; see also Figs. 2A, 2B (showing interferer signals and desired signals together).” slip op. at 17

“during trial, we determine that Petitioner has not shown by a preponderance of the evidence that Scoda discloses intercepting a web page sent from a We agree with Patent Owner that portions of Scoda cited in the Petition do not disclose a web page, let alone one sent from a server and addressed to a client browser. See PO Resp. 17; Tr. 73:10–23. Scoda discloses that “[t]he core module 21 is executed by the web content proxy server 12 to determine where to provide the response with the executed JavaScript functionality in the exemplary environment 10, such as to a web browser on one of the client devices 14(1)–14(n).” Ex. 1016 ¶ 55. But this functionality does not refer to a web page from a server. Instead, this discussion is about a HTTP request that comes from a client device and may include one or more hidden JavaScript identifiers. See id. ¶¶ 50–55. The discussion about providing a response to a web browser on a client device refers to a response to the client device’s HTTP request, in the form of an error message, that is sent from the proxy server to client device. Id. ¶ 58. As Patent Owner points out, this is one of the two scenarios presented in Scoda, the other one being that HTTP request is sent to the server. Id.; PO Resp. 36; see also Ex. 2009 ¶ 70.

We find that whether claim 1 requires the packets intercepted by the network appliance in limitation 1a to be the same packets involved in limitations 1b–1d, Petitioner has not persuasively shown that any same number of packets in Athas that are received at proxy platform 101 are then modified and forwarded as required by limitations 1b–1d, for the reasons discussed below. We agree with Patent Owner that the number of packets in limitations 1b-1d are the same, and, therefore, we find that Petitioner’s citations to Athas do not disclose the sequence of operations recited in claim limitations 1b–1d. Petitioner, therefore, does not demonstrate that Athas anticipates the claim. Specifically, we are not persuaded either by Petitioner’s assertions or Dr. Williams’s testimony that in Athas, the same “number of packets” that are received and modified by Athas’s proxy platform 101 are then forwarded to Athas’s proxy client 107, as required by limitations 1b–1d.

According to Patent Owner, a “script” is “a sequence of machine-readable instructions.” Id. (citing Ex. 1001, 3:21–23). Patent Owner proposes that we construe “executing . . . the removed embedded script” as requiring the removal of the script embedded in the web page to take place before the script is executed. Id.
