Administrative Patent Judges – You’re Fired (At Will and Without Cause)

The en banc US Court of Appeals for the Federal Circuit declined to review its October 2019 panel decision holding the appointment of administrative patent judges (APJs) at the US Patent and Trademark Office (PTO) unconstitutional because APJs are appointed as if they are “inferior officers” but vested with authority that is reserved for Senate-confirmed “principal officers” under the Constitution’s Appointments Clause.

Stated Purpose More Decisive than Definition in Construing Claims

The US Court of Appeals for the Federal Circuit reversed a Patent Trial and Appeal Board (PTAB) obviousness decision, finding the decision was infected by an erroneous claim construction that failed to consider the purpose of the claimed invention. Kaken Pharmaceutical Co., LTD v. Iancu, Case No. 18-2232 (Fed. Cir. Mar. 13 2020)(Taranto, J.).

Kaken owns a patent claiming a method for topically treating fungal infections in nails. Fungal infections of the nail plate and nail bed are notoriously difficult to treat because topical treatments cannot penetrate the thick keratin in the nail plate. The patent describes an effective topical treatment with an antifungal, KP-103, having good permeability, retention capacity and activity in the nail plate. The patent specification notes that topical treatments known in the prior art were largely ineffective at penetrating the nail plate and treating onychomycosis.

Petitioner’s Reply Argument in IPR Is Not an Impermissible New Theory

Addressing whether the Patent Trial and Appeal Board (PTAB or Board) too narrowly read its rules limiting reply briefs in an inter partes review (IPR) to preclude a petitioner’s argument as a “new theory of unpatentability,” the US Court of Appeals for the Federal Circuit concluded that the Board abused its discretion by not considering petitioner’s arguments. Apple Inc. v. Andrea Electronics Corp., Case Nos. 18-2382, -2383 (Fed. Cir. Feb. 7, 2020) (Plager, J.).

CBS Corporation, Case No. 18-2256 (Fed. Cir. Jan. 10, 2020) (Taranto, J).

IPR Institution Requires Reasonable Likelihood that Reference Is Printed Publication

In a precedential opinion, the Patent Trial and Appeal Board (PTAB) held that, for institution of an inter partes review (IPR) based on a printed publication, the petitioner must establish a reasonable likelihood that the reference is a printed publication.
