CAFC Vacates PTAB Ruling for Apple, Citing Board Error on Applicant Admitted Prior Art

The U.S. Court of Appeals for the Federal Circuit (CAFC) today vacated and remanded two decisions of the Patent Trial and Appeal Board (PTAB) on related inter partes reviews (IPRs) brought by Apple against Qualcomm, explaining that the Board’s determination that “prior art consisting of patents or printed publications” includes applicant admitted prior art (AAPA) was incorrect. The CAFC nonetheless remanded the case for the PTAB to decide “whether Apple’s petition nonetheless raises its § 103 challenge on the basis of prior art consisting of patents or printed publications.” Apple petitioned the PTAB to review the claims of U.S. Patent No. 8,063,674. In two separate decisions, the PTAB found several claims unpatentable under Section 103, basing its finding on a ground raised by Apple that relied in part on AAPA and a prior art patent. Apple also challenged the claims as unpatentable under Section 103 based on two prior patents and one publication, but the Board said that Apple had not proven unpatentability on this ground.

Practice Tips Following USPTO Guidance on Applicant Admitted Prior Art

On August 18, 2020, the USPTO issued a guidance memorandum on the treatment of applicant statements in the challenged patent in inter partes review (IPR) proceedings under Section 311, which addresses the use of applicant statements as Applicant Admitted Prior Art (AAPA). When an IPR is filed, the basis of that IPR must be prior art consisting of either a patent or printed publication. An interesting situation arises when the disclosure of the challenged patent itself admits or allegedly admits certain material as prior art. This situation has presented itself to the Patent Trial and Appeal Board (Board) on a number of occasions and has received inconsistent treatment. The purpose of this memorandum is to clarify that an applicant’s own statements in the challenged patent cannot serve as the basis for instituting an IPR. But the use of AAPA is still available as evidence the Board may consider for more limited purposes.
