Patent litigation

Ouster filed a Section 337 ITC complaint (337-TA-1363) and a companion D.Del. action against Hesai Group on April 11, 2023, asserting five digital-lidar patents: US 11,175,405 (spinning lidar micro-optics), 11,178,381, 11,190,750, 11,287,515, and 11,422,236. Ouster sought an import ban on Hesai lidar sensors. On June 22, 2023 Hesai moved to terminate, arguing that Velodyne Lidar - which merged with Ouster in February 2023 - had entered a 2020 Litigation Settlement and Patent Cross-License Agreement with Hesai Photonics requiring arbitration of patent disputes. The ITC ALJ granted Hesai's motion on August 24, 2023; the Commission affirmed on October 10, 2023. The companion Delaware case was dismissed in March 2025 without any financial settlement or injunctive relief. The substantive question of infringement was never adjudicated; Ouster was bound by Velodyne's prior contractual obligation.
