Short Summary
Google LLC has filed an IPR petition challenging 27 claims of CardWare’s U.S. Patent No. 11,176,538 covering limited‑duration payment numbers. The petition asserts obviousness over prior‑art references Gomez, Phillips, Casey, and Law, and argues that discretionary denial is not appropriate.
Detailed Summary
In a petition for inter partes review, Google LLC seeks to invalidate 27 claims of CardWare Inc.’s patent on electronic devices that generate limited‑duration numbers for payment transactions. The challenger contends that the asserted claims are obvious in view of three earlier patents—Gomez, Phillips, and Casey—covering mobile payment systems, and further adds Law as a fourth reference for a subset of claims. The petition emphasizes that the Board need not construe any claim terms because the prior art reads on them, and it disputes the applicability of discretionary denial under § 314(a). The filing references multiple related district‑court litigations and prior IPRs, some of which were settled, and requests that the PTAB institute the trial on the identified claims.
