U.S. Supreme Court Denies Writ to Overturn Application of the Kessler Doctrine

The USPTO Director denied a patent owner’s request for discretionary denial of two inter partes review (IPR) petitions, citing the petitioner’s “well-settled expectation” that it would not be accused of infringing the two challenged patents. The Director’s conclusion was based on the petitioner’s decade-long business relationship with the original owner of the challenged patents.

The Southern District of Florida recently dismissed a complaint without prejudice because the allegations used a form of “shotgun pleading.” The court explained that a shotgun pleading includes those where every count incorporates every preceding paragraph into each cause of action, and that dismissal of such pleadings was required under Eleventh Circuit precedent.

The Federal Circuit recently addressed whether the PTO must conduct notice‑and‑comment rulemaking before issuing instructions that guide how the Board should exercise discretion at the institution stage of IPRs. The court held that no such rulemaking is required. Instructions to the Board regarding its use of the Director’s delegated discretionary authority not to institute review are merely general statements of policy exempt from notice-and-comment rulemaking.  

The District Court for the District of Delaware recently invalidated claims directed to a panoramic objective lens for lack of enablement, holding the claims impermissibly recited a single element in means‑plus‑function form. Under § 112, ¶ 6, “[a]n element in a claim for a combination may be expressed as a means or step for performing a specified function….” By its plain terms, the statute permits means‑plus‑function claiming only in the context of a “combination.” In other words, a claim may not consist solely of a single means‑plus‑function element. Claims drafted as a single means are invalid for lack of enablement as a matter of law.
