Core Viewpoint - Lam Research has become a significant concern for South Korean materials, parts, and equipment (MP&E) companies due to its aggressive patent infringement lawsuits against them, despite most cases being dismissed by South Korean courts [1][2]. Group 1: Patent Infringement Lawsuits - Since the outbreak of the Japan-South Korea semiconductor materials trade dispute in 2020, Lam Research has filed 12 patent infringement lawsuits against South Korean companies, with 9 occurring after the establishment of its R&D center in Yongin, Gyeonggi Province in 2022 [1]. - The number of patents registered by Lam Research in South Korea surged from 68 in 2020 to 344 by 2025, raising concerns in the South Korean semiconductor equipment industry about the implications of such extensive patent registrations [1]. - Lam Research's lawsuits are seen as a tactic to delay the technological advancements of South Korean competitors, as the company can afford to file lawsuits without the immediate need for winning them [2]. Group 2: Legal Outcomes and Industry Impact - In a notable case, Lam Research lost a patent infringement lawsuit against CMTX, which led to CMTX successfully invalidating Lam's patent. The court ruled that Lam's patent lacked creativity, highlighting the challenges faced by Lam in its legal pursuits [3]. - Lam Research also faced defeat in a lawsuit against MP&E company PSK, where two of its claimed patents were declared invalid. In the past year alone, six of Lam's patents were invalidated [3]. Group 3: Calls for Government Action - There is a growing demand for government intervention to protect domestic technologies, as the ongoing patent lawsuits have adversely affected many companies, particularly small and medium-sized enterprises [4]. - The South Korean Intellectual Property Office provides legal consulting services to companies embroiled in patent disputes, but critics argue that the number of companies not receiving assistance is increasing due to the widespread nature of Lam Research's lawsuits [4]. - Lawmakers emphasize the need to minimize damages to local enterprises and prevent unnecessary litigation, especially during a period of significant growth in the semiconductor industry [5].
