“This query could appear fairly within the weeds…nevertheless it does spotlight the truth that publish grant challenges on the PTAB are a mongrel combination of somewhat bit prosecution, somewhat bit litigation, and an entire lot of uncertainty.”
A current Publish Grant Overview (PGR) petition raises a number of fascinating questions, together with whether or not the crossing of two types of corn beforehand crossed and already owned by the patent proprietor ends in a non-obvious claimed invention. See Inari Agriculture, Inc. v. Pioneer Hello-Bred Worldwide, Inc., PGR2024-00025. However as fascinating as that obviousness query could also be, and the way simple it appears it’s to get a utility plant patent issued, the query of higher concern for the system pertains to which take a look at for indefiniteness the U.S. Patent and Trademark Workplace (USPTO) needs to be utilizing, and why.
Nautilus or Packard—that’s the query introduced by the Inari PGR problem of a utility plant patent owned by Pioneer Hello-Bred Worldwide—U.S. Patent No. 11,707,033. And whereas the requirements for indefiniteness are related, they aren’t the identical.
The method adopted by the USPTO for assessing indefiniteness throughout prosecution is the method permitted by the Federal Circuit in In re Packard – “[a] declare is indefinite when it incorporates phrases or phrases whose that means is unclear.” 751 F.3d at 1310, 1314. Put in a different way, “claims are required to be solid in clear-as against ambiguous, obscure, indefinite-terms.”
Nonetheless, in litigation, the take a look at used for figuring out whether or not a declare is indefinite and have to be invalidated comes from Nautilus v. Biosig, 134 S. Ct. 2120 (2014), which the Courtroom defined mandates readability, whereas nonetheless recognizing that absolute precision is unattainable. Extra particularly, the Supreme Courtroom in Nautilus wrote:
“We conclude that the Federal Circuit’s formulation, which tolerates some ambiguous claims however not others, doesn’t fulfill the statute’s definiteness requirement. Rather than the “insolubly ambiguous” customary, we maintain {that a} patent is invalid for indefiniteness if its claims, learn in mild of the specification delineating the patent, and the prosecution historical past, fail to tell, with cheap certainty, these expert within the artwork in regards to the scope of the invention.”
Flip-Flop
However what’s the customary that ought to apply in PGR and IPR? Ought to the Patent Trial and Enchantment Board (PTAB) be making use of the Packard customary utilized throughout examination, or the Nautilus customary utilized throughout litigation? The USPTO place has flip-flopped on this query, and so far the Federal Circuit and Supreme Courtroom have dodged the query.
The PTAB in Ex partre McAward, a precedential opinion in an ex parte enchantment taken from an examiner’s last rejection of claims, wrote:
“We acknowledge that after the Packard determination, the Supreme Courtroom in Nautilus, Inc. v. Biosig Devices, Inc. defined that the “definiteness command” of §112, para. 2 “require[s] {that a} patent’s claims, seen in mild of the specification and prosecution historical past, inform these expert within the artwork in regards to the scope of the invention with cheap certainty.” The Courtroom acknowledged that “[t]he definiteness requirement, so understood, mandates readability, whereas recognizing that absolute precision is unattainable.” Id. We don’t perceive Nautilus, nevertheless, to mandate a change within the Workplace’s method to indefiniteness…
Thus, on this continuing, we apply the method for assessing indefiniteness permitted by the Federal Circuit in Packard, i.e., ‘[a] declare is indefinite when it incorporates phrases or phrases whose that means is unclear.’ 751 F.3d at 1310, 1314. Put in a different way, “claims are required to be solid in clear-as against ambiguous, obscure, indefinite-terms.”
Equally, the 12 months earlier than McAward, in a publish grant problem in Telebrands v. Tinnus Enterprises, the PTAB wrote:
“[W]e apply the take a look at for indefiniteness permitted by the Federal Circuit in Packard, i.e., “a declare is indefinite when it incorporates phrases or phrases whose that means is unclear.” We acknowledge that Packard concerned a USPTO patent-examination matter. We additionally acknowledge that subsequent to the Packard determination, the Supreme Courtroom in Nautilus enunciated a in a different way worded definiteness requirement within the context of patent infringement litigation. We don’t perceive Nautilus, nevertheless, to mandate the Board’s method to indefiniteness in patent examination or reexamination issues or in AIA proceedings, by which the claims are interpreted beneath the broadest cheap interpretation customary, and a possibility to amend the claims is afforded. The take a look at for indefiniteness permitted in Packard, which is utilized by the USPTO in patent examination, units a threshold for indefiniteness that calls for not less than as a lot readability, and probably extra readability, than the Nautilus definiteness requirement. See MPEP § 2173.02(I).”
Thus, it appeared settled, the USPTO follows Packard, not Nautilus. However then in 2021 a jointly issued memo from USPTO Director Andrei Iancu, Commissioner for Patents Drew Hirshfeld, and PTAB Chief Choose Scott Boalick modified all the pieces.
This 2021 memo defined a change was obligatory as a result of in 2018 the workplace revised 37 CFR 42.100(b) and 42.200(b) to vary the declare constructions customary utilized in post-grant trial proceedings from the broadest cheap interpretation to make use of the declare development customary employed in civil patent infringement litigation. The memo additional defined:
“The workplace now clarifies that the Board shall comply with Nautilus in AIA post-grant proceedings. As a result of the workplace’s declare development customary in AIA post-grant proceedings now aligns with that utilized by courts in a civil motion, and since indefiniteness questions are usually thought of as a part of the declare development course of, the workplace’s method to indefiniteness in AIA post-grant proceedings ought to likewise align with that utilized by the courts following the Supreme Courtroom’s determination in Nautilus. As with the declare development customary, aligning the indefiniteness method in AIA post-grant proceedings will promote consistency and environment friendly determination making amongst coordinate branches of presidency that determine related points in co-pending proceedings. This memorandum confirms, due to this fact, that Nautilus is the proper method for analyzing indefiniteness in AIA post-grant proceedings.”
Since, the PTAB has utilized Nautilus, which is now being particularly questioned as being constructed on a defective premise, and likewise as “an improper company rule made exterior of correct Discover-and-Remark-Rulemaking.” Petition for Publish-Grant Overview, PGR2024-00025, web page 10.
Let’s Cease the Flop
This query could appear fairly within the weeds, and unlikely to matter for many indefiniteness inquiries, nevertheless it does spotlight the truth that publish grant challenges on the PTAB are a mongrel combination of somewhat bit prosecution, somewhat bit litigation, and an entire lot of uncertainty. It additionally highlights the chance of one other flip-flop sooner or later. If this may be completed through memorandum and outdoors company rulemaking, then it may be undone by memorandum if and when the following Director disagrees.
