Federal Circuit: Applicant Admitted Prior Art Cannot Provide a "Basis" for a Ground of Unpatentability in an IPR, But Can be Cited for Other Purposes

When Congress enacted the America Invents Act and created the inter partes review (IPR) proceeding, it limited an IPR petition to challenging patentability "only on a ground that could be raised under section 102 or 103 [i.e., anticipation and obviousness] and only on the basis of prior art consisting of patents or printed publications." 35 U.S.C. § 311(b). Can the patentee's admissions as to the scope and content of prior art in its own patent or patent application — commonly referred to as applicant admitted prior art (AAPA) — be used in an IPR? According to the Federal Circuit, the answer to that question is "yes" — but not as a "basis" for a ground of unpatentability.

In Qualcomm Inc. v. Apple Inc., Nos. 2020-1558, -1559, 2022 WL 288013 (Fed. Cir. Feb. 1, 2022), Apple filed two petitions for inter partes review, which challenged different claims of the same patent. Both petitions asserted the same two prior-art grounds against the different challenged claims: 1) obviousness over the combination of the "Steinacker" patent, the "Doyle" patent, and the "Park" publication; and 2) obviousness over the combination of the "Majcherczak" publication and AAPA consisting of "Figure 1 and its accompanying description" in the challenged patent.
