QUALCOMM INCORPORATED v. INTEL CORPORATION, Appeal Nos. 2020-1589, 2020-1590, 2020-1591, 2020-1592, 2020-1593, 2020-1594 (Fed. Cir. July 27, 2021).  Before Moore, Reyna, and Stoll.  Appealed from the PTAB. (Claim Construction; Procedural Rights)


Intel filed six inter partes reviews (IPRs) against Qualcomm’s patent directed to a power tracker for a circuit that processes multiple radio frequency signals (e.g., signals transmitted on multiple carrier frequencies).  In each IPR, Intel proposed a construction of the claim term “a plurality of carrier aggregated transmit signals” to mean “signals for transmission on multiple carriers…to increase the bandwidth for a user.”  Qualcomm proposed “signals…utilizing multiple component carriers which provide extended transmission bandwidth for a user transmission…”  As such, Qualcomm and Intel never disputed that the signals were required to increase (or extend) the user bandwidth.  In a parallel proceeding before the International Trade Commission (ITC), the ITC’s construction also included the increased bandwidth requirement.  In sum, all briefings by both parties in all six IPRs as well as the ITC’s construction included the increased bandwidth requirement.

After the completion of briefing and during a two-hour oral hearing before the Board, one judge asked Intel a single question about the increased bandwidth requirement.  Neither that judge nor the other two judges on the panel asked Qualcomm any questions on the matter.  In fact, the Board ordered additional briefing the next day on a different claim construction issue, but it never requested any briefing on the increased bandwidth requirement.  The Board then issued six final written decisions finding all challenged claims unpatentable based on the Board’s construction that omitted any requirement that the signals increase or extend the user bandwidth.  Qualcomm argued that it was not given notice of, or an adequate opportunity to respond to, the Board’s construction, and thus the Board had violated Qualcomm’s procedural rights under due process and the Administrative Procedure Act.  Qualcomm appealed.
