• Hesai has had multiple patent infringement claims filed against it
• Ouster holds one of the largest patent families in the lidar industry, with successful enforcement and defense of its patent portfolio

SAN FRANCISCO / Apr 12, 2023 / Business Wire / Ouster, Inc. (NYSE: OUST) (“Ouster” or the “Company”), a leading provider of high-performance lidar sensors for the automotive, industrial, robotics, and smart infrastructure industries, announced today that it has filed a patent infringement complaint with the U.S. International Trade Commission (ITC) against Hesai Group (Nasdaq: HSAI) based in Shanghai, China, and related entities, requesting that the Commission institute an investigation under section 337 of the Tariff Act of 1930. Ouster also filed a patent infringement complaint against Hesai in the U.S. District Court for the District of Delaware, seeking an injunction and monetary damages.

Ouster's complaint asks the ITC to investigate unlawful imports of Hesai lidar sensors that infringe on five valid and enforceable patents owned by Ouster relating to lidar technology (U.S. Patents 11,175,405; 11,178,381; 11,190,750; 11,287,515; and 11,422,236). Ouster’s complaint requests that the ITC issue a limited exclusion order and a cease and desist order against Hesai and related entities to bar the importation into the United States of Hesai's lidar devices, components, and products that are alleged to infringe Ouster's patents.

Ouster invented digital lidar technology following an engineering breakthrough, resulting in a high-resolution sensor with a simplified architecture based on two silicon chips. Ouster’s highly flexible digital platform can be manufactured at scale and unlocks the largest market opportunity with a combination of high-performance and low cost. As a result, Ouster has quickly become a market leader in lidar. Ouster holds one of the largest patent families in the lidar industry with hundreds of granted and pending patents, which have been successfully enforced. Ouster’s patents reflect the substantial investments the Company has made in the United States relating to both rotating and non-rotating solid-state lidar systems. Ouster's complaint sets forth how, after the market shifted toward Ouster’s digital lidar, Hesai stole Ouster’s revolutionary patented technologies and incorporated them into Hesai’s competing products.

This is not the first time that a U.S. company has brought a patent infringement claim against Hesai. In 2019, Velodyne Lidar¹ brought a patent infringement lawsuit against Hesai. Hesai settled for payment of millions of dollars upfront and ongoing royalties. Ouster will continue to vigorously enforce its patents until the infringing products are barred.

“We set out to build a lidar company based on a digital approach because we knew that it would make lidar performant, affordable, and ubiquitous. Ouster intentionally built one of the strongest patent portfolios in the industry,” said Ouster CEO Angus Pacala. “As companies attempt to copy our digital approach, we will continue to vigorously enforce our intellectual property until the infringing products are barred. Lidar is a critical technology providing vision for advanced automation and smart technologies across supply chains, infrastructure, and defense. The global lidar industry relies on fair competition, and IP must be protected.”
