Detailed Summary

In a petition for inter partes review (IPR2025‑01446), Airwallex Pty. Ltd. requests the PTAB to institute a trial and cancel claims 1‑16 of U.S. Patent No. 11,620,701, which covers a platform for trading assets across different currencies. The challenger contends that the claimed inventions are obvious under 35 U.S.C. §103 in view of the combined teachings of five prior‑art references—Calo, Rude, Sellberg, Szoc, and Davidowitz—each of which discloses the essential elements of the platform. The petition also points to the examiner’s double‑patenting rejections during prosecution and emphasizes that a person of ordinary skill would have been motivated to combine these references. The patent is the subject of seven pending infringement actions in the Eastern District of Texas, making the outcome of the IPR potentially impactful for ongoing litigation.
