Not long ago, there was news in the market that Suteng Juchuang sued the chip design company Smart Photonics for “allegedly infringing on technical secrets related to self-developed SPAD chips,” which attracted widespread attention in the industry. On December 10, Ling Ming Guangzi issued a statement on its WeChat account, stating, “There is no risk that our company infringes on Suteng Juchuang's patents and technical secrets; on the contrary, Sagiteng Juchuang actually infringes on intellectual property rights and trade secrets.” The reporter learned from people familiar with the matter in the industry that Sutengjuchuang began to lay out independent research and development of lidar chips in 2017, and was the first in the world to mass-produce digital lidar with self-developed SPAD chips in 2024. During this period, Lingming Photon had a brief cooperation with Sutengjuchuang. This may be the origin of the current Suteng Juchuang lawsuit.
