In one of the first decisions regarding derivation proceedings under the America Invents Act (AIA), the US Court of Appeals for the Federal Circuit affirmed the Patent Trial & Appeal Board’s finding that an application earlier filer had not derived his claimed invention from a later-filing petitioner. Global Health Solutions, LLC v. Marc Selner, Case No. 2023-2009 (Fed. Cir. Aug. 26, 2025) (Stoll, Stark, JJ.) (Goldberg, J., sitting by designation).
Global Health Solutions (GHS) and Marc Selner filed patent applications governed by the AIA and covering similar subject matter. Selner filed his application first. GHS filed a petition to institute derivation under 35 U.S.C. § 135, alleging that Selner’s patent claims were derived from Burnam, the single inventor on the GHS application.
During Board proceedings, the parties submitted evidence regarding the timing of their respective conceptions of the claimed inventions, including several email communications. Based on Selner’s evidence, the Board determined that he could not have derived the claimed invention from Burnam. The Board also rejected GHS’s argument that actual reduction to practice was necessary to complete conception of the claimed invention. GHS appealed.
The Federal Circuit explained that while pre-AIA patent interference proceedings required a party alleging derivation to establish prior conception and communication of the invention to the opposing party, the AIA does not expressly define the evidentiary requirements for derivation petitions. Nevertheless, the Court, borrowing from its interference jurisprudence, reasoned that an AIA derivation proceeding similarly requires a showing of both conception and communication of the claimed invention. The Court emphasized, however, that standards articulated in case law from pre-AIA interference proceedings must be applied with caution and considered in light of the AIA’s distinct statutory framework.
The Federal Circuit determined that although the Board focused on which party had proof of the earliest conception (typically the dispositive issue in interference proceedings), it was harmless error. Under the AIA first-to-file framework, determination of the first to invent is not dispositive. The Court noted that because Selner was first to file, he only needed to show that his conception was independent of Burnam’s. Here, Selner’s proof of earlier conception was also proof of conception independent of Burnam, the Court noted.
The Federal Circuit also determined that the Board did not err in rejecting GHS’s argument that Selner failed to demonstrate invention in the absence of evidence of actual reduction to practice. The Court found that the Board appropriately addressed whether such a requirement (often applied in interference proceedings to complicated, unpredictable technology) applied to the invention at issue. The Court explained that Selner’s conception was complete either when he could define the invention by its method of preparation or when he had formed a definite and permanent idea of the complete and operative invention. Selner’s earlier email communication to Burnam supported the finding that Selner had reached the requisite understanding to establish complete conception without the need for actual reduction to practice. Accordingly, the Court affirmed the Board’s decision in favor of Selner, finding no derivation.
Practice note: This case highlights the fundamental distinction between AIA derivation and pre-AIA interference analyses. Under the AIA, the focus is not on who invented first, but whether the first filer actually derived their invention from the petitioner based on petitioner’s earlier invention and relevant communication of the invention to the accused deriver.
