The Federal Circuit recently reversed a PTAB determination on remand that a patent was obvious over applicant admitted prior art (“AAPA”) in combination with prior art patents, holding that expressly designating AAPA as a “basis” for a ground is improper under 35 U.S.C. § 311(b). In doing so, the Court rejected the PTAB’s “blanket rule” that “AAPA used in combination with prior art patents or printed publications under § 311(b) is ipso facto not the basis or part of the basis of a ground.” Ultimately, while the case clarifies that expressly listing AAPA in an IPR ground is improper, the precise line between proper and improper uses of AAPA in other instances remains unclear.

The Federal Circuit affirmed a District of Delaware finding of non-infringement in an ANDA litigation due to the patentee’s clear and unmistakable disavowal of claim scope during prosecution. Specifically, the court held that statements made during prosecution of a parent application before the asserted claims were allowed amounted to a prosecution disclaimer that extended to subsequent patents in the family. In reaching this conclusion, the court rejected an attempt by the patentee to resurrect the claim scope through a unilateral, self-serving statement made in later applications in the family.

The Federal Circuit recently affirmed a district court’s holding that patent term extension (PTE) for a reissued patent was properly based on the issue date of the original patent and not that of the reissued patent.
