Seven years after the PTAB instituted the first AIA derivation proceeding, the Federal Circuit finally issued its first opinion in an appeal of a derivation decision, Global Health Solutions, LLC v. Selner, No. 23-2009 (Fed. Cir. 2025), affirming the Board’s decision that the petitioner did not carry its burden to show respondent (Selner)
The Patent Office is not supposed to issue separate patents for the same invention to competing inventors. Several statutory provisions empower the Office to reject pre-AIA patent application claims of the later inventor. But sometimes it’s not clear who is the later inventor. Those provisions are therefore unhelpful. So, the Patent Trial and Appeal Board administers an increasingly rare proceeding called an “interference” to assesses which inventor was the last to invent. Through this proceeding, the Office cancels as unpatentable (under pre-AIA 35 USC § 102(g)) the claims of the inventor the Board determines was last to invent.Continue Reading Patent Interferences May Not Involve Pure AIA Patent
A patent interference is an adversarial proceeding where each party is trying deprive its opponent of a patent on an invention that that the Patent Office has already decided is patentable. Long after the AIA became effective to phase out interferences, the Patent Trial and Appeal Board continues to declare and administer them where at least one of the parties has an interfering application or patent predating the AIA’s enactment. The Board declares interferences to avoid the embarrassment and marketplace chaos where the Patent Office issues two patents on the same invention to different parties, and to avoid awarding a patent monopoly to the entity who was not the first to invent.

If the Federal Circuit’s decision in Arthrex wasn’t sufficiently newsworthy, then look at what lurks in its wake. The day after the decision, the court issued precedential orders indicating that a timely Constitutional challenge apparently must be presented to the court in an opening brief. A few days after those orders, two of the court’s most senior active-service judges said that the court’s remedy in Arthrex (i) wasn’t required by Supreme Court precedent, (ii) imposed unnecessary burdens on all involved in AIA trials, (iii) requires hundreds of new proceedings, and (iv) involves decision-making that is itself unconstitutional. And a day later, another panel of the court issued an order soliciting briefing on those and other issues left in Arthrex’s wake, tacitly questioning the Arthrex panel’s decision.Continue Reading Haste Makes Waste?
In General Hospital Corp. v. Sienna Biopharmaceuticals, Inc., Case No. 2017-1012 (Fed. Cir. May 4, 2018), the Federal Circuit affirmed the PTAB’s August 2016 decision that General Hospital Corporation’s (GHC) claims involved in an interference proceeding (that GHC requested) failed to meet the written description requirement. But the court also vacated the PTAB’s denial of GHC’s contingent motion to add a new claim as arbitrary and capricious because the PTAB did not follow its own Standing Order. The court therefore remanded the case to the PTAB to decide remaining issues in the interference.
