"The '450 Patent is or has been involved in at least 23 district court proceedings. The patent issued in 2019 but claims priority back to 2005. It purports to address a core problem in wireless networks: excessive overhead control in multi-carrier wireless communication networks that reduces bandwidth efficiency, particularly in systems based on IEEE 802.16. By introducing "time-frequency resources" and application-specific zones, the patent is alleged to improve spectral efficiency-a concept with broad implications for modern vehicle connectivity."
"In September 2022, Volkswagen filed a petition for IPR challenging all 18 claims of the '450 Patent, which was later joined by Honda, GM, Nissan, and Tesla. The petition argued obviousness under pre-AIA §103 based on multiple prior art references, including publications by Vijayan, Laroia, Wu, and Choi. This first IPR turned on claim construction. Central to the challenge was the meaning of "starting time‑frequency coordinate" in the claims. The Board sided with the Patent Owner and adopted a construction that the term cannot be disclosed by teachings of separate time and frequency coordinates."
The PTAB again upheld the validity of Neo Wireless U.S. Patent No. 10,447,450, most recently in Ford Motor Co. v. Neo Wireless (Sept. 3, 2025), following a similar decision from Nov. 1, 2024. The '450 Patent has been litigated in at least 23 district court proceedings, issued in 2019 with priority back to 2005. The patent addresses excessive overhead control in multi-carrier wireless networks and proposes time-frequency resources and application-specific zones to improve spectral efficiency for vehicle connectivity. Multiple automakers pursued IPRs challenging all claims on obviousness grounds, but claim construction and evidentiary burdens led the Board to sustain the patent.
