激光雷达芯片“疑云”：灵明光子称“不存在对速腾聚创侵权风险”

Core Viewpoint - The legal dispute between Suoteng Juchuang and Lingming Photon over alleged infringement of self-developed SPAD chip technology has garnered significant industry attention [1]. Group 1: Company Background - Suoteng Juchuang has been focusing on the independent research and development of laser radar chips since 2017, aiming to achieve mass production of self-developed SPAD chips for digital laser radar by 2024 [1]. - Lingming Photon claims that it does not infringe on Suoteng Juchuang's patent rights and asserts that Suoteng Juchuang may be the one infringing on its intellectual property [5]. Group 2: Technology Comparison - Suoteng Juchuang specializes in digital laser radar, utilizing single-photon avalanche diodes (SPAD) that allow each detection pixel to independently receive single photons and generate digital pulse signals [3]. - The industry also recognizes an alternative technology route, analog laser radar, which relies on silicon photomultiplier tubes (SiPM) or traditional photodiodes (APD) that require signal processing before digital conversion [3]. Group 3: Industry Opinions - There is ongoing debate within the industry regarding the advantages of digital versus analog laser radar technologies [4]. - Suoteng Juchuang's CEO emphasizes the superiority of digital laser radar using SPAD architecture, claiming it leads to higher line density, resolution, and point cloud quality [4]. Group 4: Legal Developments - Lingming Photon has publicly stated that it has not received any legal documents related to the lawsuit as of December 1 [5]. - Following the initial statement, Lingming Photon reiterated on December 10 that it has not received any litigation materials and is preparing to investigate potential patent infringement by Suoteng Juchuang [5].
