Detailed Summary
In a petition for post‑grant review (PGR2026‑00008), Kia America, Inc., Toyota Motor Corp., and related entities challenge U.S. Patent No. 12,337,715 owned by Emerging Automotive LLC. The petition asserts two grounds: (1) obviousness under 35 U.S.C. §103, combining Sekiyama (Toyota), Kleve (Ford), Hatton (Ford), and Xiao (Verizon) to anticipate the claimed method of sharing electronic vehicle keys; and (2) lack of written description and enablement under 35 U.S.C. §112(a) for claim limitations requiring a “message‑caused” initiation and confirmation steps that are not disclosed in the specification. The petition requests that the PTAB institute the proceeding and cancel claims 1‑24. No decision has been issued yet.
