“interpreted Rule 42.73(b) as permitting the Board to enter adverse judgment when a patent owner disclaims all challenged claims prior to institution. See Arthrex, Inc. v. Smith & Nephew, Inc., 880 F.3d 1345, 1350 (Fed. Cir. 2018). But neither Arthrex nor Rule 42.73(b) require the entry of adverse judgment. Instead, under these circumstances, the Board has discretion to decide whether or not to enter adverse judgement. See, e.g., Bestway (USA), Inc. v. Intex Mktg., Ltd., PGR2024-00036, Paper 9, 6 (PTAB Oct. 28, 2024) (“Bestway”). Based on the facts of this case, we believe that efficient administration weighs against entry of adverse judgment. Thus, consistent with Rule 42.107(e) and General Electric, denial of institution is sufficient to dispose of this matter. See, e.g., Bestway at 8; Samsung Electronics Co., Ltd. v.

Furthermore, Patent Owner offers information suggesting that “the breeding of 1PNZQ23 was unpredictable even with both parents being known in the art.” Prelim. Resp. 47. Dr. Schnable addresses unpredictability in the breeding process, stating: distinct even when the F1 plant itself results from a cross of two inbreds. A [person of ordinary skill in the art] would not expect that a cross of the same parents will produce F2 or D1 progeny identical to 1PNZQ23. . . . [T]he genome of a progeny plant is the result of genetic segregation and recombination in the F1 plant of the two parental genomes and the chance of the exact same child resulting from that initial biparental cross is infinitesimally small.

“their cross ultimately resulted in the inbred variety 1PFLQ21.

The ’803 patent specification, therefore, makes it clear that simply crossing both parental inbred maize lines is not reasonably expected to result in the claimed inbred maize variety; rather, it explains that more plant breeding work is required to arrive at the 1PFLQ21 inbred maize line than just having both parental inbred maize lines available.” slip op. at 15

“review, “the Director may take into account whether, and reject the petition or request because, the same or substantially the same prior art or arguments previously were presented to the Office.”3 Our § 325(d) analysis employs a two-prong framework: (1) whether the arguments presented in the petition are the same or substantially the same as those previously presented to the Office; and (2) if so, whether the petitioner has demonstrated a material error by the Office in its prior consideration of those arguments.

Advanced Bionics, 9. These non-exclusive factors include: (a) the similarities and material differences between the asserted art and the prior art involved during examination; (b) the cumulative nature of the asserted art and the prior art evaluated during examination; (c) the extent to which the asserted art was evaluated during examination, including whether the prior art was the basis for rejection; (d) the extent of the overlap between the arguments made during examination and the manner in which Petitioner relies on the prior art or Patent Owner distinguishes the prior art; (e) whether Petitioner has pointed out sufficiently how the Examiner erred in its evaluation of the asserted prior art; and (f) the extent to which additional evidence and facts presented in the Petition warrant reconsideration of the prior art or arguments. Becton, Dickinson, 17–18 (formatting added). “If, after review of factors (a), (b), and (d), it is determined that the same or substantially the same art or arguments previously were presented to the Office, then factors (c), (e), and (f) relate to whether the petitioner has demonstrated a material error by the Office.” Advanced Bionics, 10.” slip op. at 10
- Skill levelSkill level petitioner adoptedDecided for petitioner
“Petitioner contends that a person of ordinary skill in the art: would have had an advanced degree like a Ph.D. or equivalent in chemistry, biochemistry, pharmaceutics, pharmacy, or a related pharmaceutical field, with at least two years of experience in pharmaceutical formulation development, analysis, optimization and manufacturing, including experiences with processes and techniques for minimizing impurities in, and improving the stability of, pharmaceutical drug products during manufacture and storage. Pet. 27 (citing Ex. 1003 ¶ 24). Petitioner also states that one of ordinary skill in the art “may also have lesser levels of education but more years of experience” and “[a] multi-disciplinary team consisting of individuals with different skills and experience could also suffice.” Id. Patent Owner argues that: A person of ordinary skill in the art has attained a Pharm. D., or M.S. or Ph.D. in chemistry, chemical engineering, or a related field; has three or more years of experience in developing aqueous drug formulations; and has access to other scientists to collaborate and consult with on, for example, characterizing the drug formulation, manufacture of the drug formulation, and clinical use and effect of the drug formulation.” slip op. at 7

A “transition application” is a patent application filed on or after March 16, 2013 (the effective date of the AIA), but which claims priority to an application that was filed prior to the effective date of the AIA. See, e.g., MPEP § 2159.04. challenged claims, or a claim pending during examination of the ’266 application, “was not disclosed in compliance with the written description and enablement requirements of § 112(a) in the earlier application for which the benefit of an earlier filing date prior to March 16, 2013 was sought.” Inguran, LLC v.

“Thus, the ’284 patent specification explains that the system can adjust the positive airway pressure supplied to the subject without human intervention. The system gathers information from the sensors and uses it to “monitor the condition of the subject” and “determine a level of severity of the subject’s sleeping disorder.” Ex. 1001, 23:20–41. Based on this the subject,” for example by adjusting the positive airway pressure provided to the subject. See id. at 19:3–17, 3:37–55. In this way, the ’284 patent specification discloses generating “an index of treatment efficacy” where “the index [is] based in part on data of severity of sleep disorder symptoms of the subject and data of usage of the PAP device by the subject,” because the system uses data collected from the sensors to evaluate the severity of the subject’s sleeping disorder and efficacy of the current treatment, and can adjust the treatment without human intervention as needed. Accordingly, Petitioner has not demonstrated that it is more likely than not that the ’284 patent claims lack written description support in the pre-AIA priority applications for “an index of treatment efficacy” claim term.” slip op. at 13

“’284 patent claims are not enabled. Prelim. Resp. 24–30. We find that Petitioner has failed to demonstrate, more likely than not, that any experimentation would have been undue in view of the Wands factors. Prelim. Resp. 25 (citing Wands, 858 F.2d at 737). On this record, Petitioner has not demonstrated that the claimed subject matter is unpredictable or would require undue experimentation. Petitioner argues that “the challenged claims are not enabled regarding the ‘index of treatment efficacy’ claim elements.” Pet. 24. But as Patent Owner establishes, Petitioner acknowledges that determining treatment efficacies was merely applying a known technique. See Prelim. Resp. 26 (citing Pet. 36 (determining treatment efficacy “would amount to merely applying a known technique (i.e., determining treatment efficacy based on multiple factors) to a known device ready for improvement (e.g., CPAP treatment system comprising multiple devices) to yield predictable results (i.e., improve operation of CPAP treatment to better treat the patient and its disorder)”). On this record, Patent Owner further demonstrates that “it was well- known in the art [] how to determine indices of treatment efficacy based on breathing metric data over a period of time.” Prelim. Resp. 26; Ex. 2001 at 175 (“Efficacy, in the context of [obstructive sleep apnea] OSA, reflects the ability of treatment to prevent the occurrence of obstructive breathing events during periods when the treatment is being physically applied.”); Ex. 2002 at 1–2 (based on the apnea-hypopnea index (AHI) the severity of obstructive sleep apnea (OSA) can be calculated); Ex. 2003 at 1 (“ResLink presents this efficacy information along with integrated oximetry data for simultaneous onscreen viewing and analysis.”)). index of treatment efficacy on a cell phone or transmitting it to a remote internet site.” Pet. 25. Petitioner, however, has not demonstrated, more likely than not, that it would take undue experimentation to carry out such display or transmission. The Petition merely suggests that the specification lacks enablement of these claim limitations, but fails to provide any analysis of pertinent factors, such as the state of the prior art, the level of ordinary skill, or the level of predictability in the art with regard to displaying and transmitting data on a cell phone at the time of the invention. In sum, we conclude that Petitioner has failed to show that it is more likely than not that the challenged claims are not enabled.” slip op. at 23

“In this post-grant review, we construe the claims of the ’284 patent “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. § 282(b).” 37 C.F.R. § 42.200(b) (2019). Under that standard, the words of a claim are generally given their “ordinary and customary meaning,” which is the meaning the term would have to a person of ordinary skill at the time of the invention, in the context of the entire patent including the specification. Phillips v. AWH Corp., 415 F.3d 1303, 1312–13 (Fed. Cir. 2005) (en banc). Petitioner contends that “[n]o claim term needs formal construction for purposes of evaluating the prior art in this Petition.” Pet. 16. Patent Owner also does not construe any claim terms. See generally Prelim. Resp. For purposes of this Decision, and based on the record before us, we determine that none of the claim terms requires an explicit construction to determine whether to institute post-grant review. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 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.’” (quoting Vivid Techs., Inc. v. Am.
