The US Court of Appeals for the Federal Circuit established a more demanding test for determining whether a published patent application claiming priority to a provisional application is considered prior art under pre-America Invents Act (AIA) 35 U.S.C. § 102(e) as of the provisional filing date, explaining that all portions of the published patent application that are relied upon by the US Patent & Trademark Office (PTO) to reject the claims must be sufficiently supported in the provisional application. In re Riggs, Case No. 22-1945 (Fed. Cir. Mar. 24, 2025) (Moore, Stoll, Cunningham, JJ.)
Several inventors who work for Odyssey Logistics filed a patent application directed to logistics systems and methods for the transportation of goods from various shippers by various carriers across different modes of transport (e.g., by rail, truck, ship, or air). PTO rejected the application under § 102(e) in view of Lettich, which claimed the benefit of a provisional application (Lettich provisional), and as obvious in view of Lettich in combination with the Rojek reference.
The inventors appealed the Lettich rejections to the Patent Trial & Appeal Board, arguing that Lettich did not qualify as prior art under § 102(e). The Board initially agreed with the inventors, but the Examiner assigned to the application requested a rehearing, asserting that the Board applied the incorrect standard for § 102(e) prior art. The Board ultimately issued its decision on the Request for Rehearing, stating that it had jurisdiction over the Examiner’s request and that the Examiner’s arguments regarding Lettich’s status as prior art under § 102(e) “[we]re well taken.” The Board amended its original decision “to determine that Lettich is proper prior art against the instant claims.” The Board then reviewed and affirmed the Examiner’s anticipation and obviousness rejections. The inventors appealed.
The Federal Circuit vacated and remanded the Board’s decision. With respect to whether Lettich qualified as § 102(e) prior art, the Court found that the Board’s analysis was incomplete. The Court concluded that the Board correctly applied the test set forth in the Federal Circuit’s 2015 decision in Dynamic Drinkware v. National Graphics by determining that the Lettich provisional supported at least one of Lettich’s as-published claims. However, the Court found that this test was insufficient because all portions of the disclosure that are relied upon by the PTO to reject the claims must also be sufficiently supported in the priority document. Although the PTO asserted that the Board had conducted this additional analysis, the Federal Circuit disagreed and vacated and remanded for the Board to determine whether the Lettich provisional supported the entirety of the Lettich disclosure that the Examiner relied on in rejecting the claims.
