The core of TSMC's (NYSE: TSM) complaint centers on Lo Wei-jen, a highly respected executive who served TSMC for over two decades, rising to the position of Senior Vice President. Lo retired from TSMC in July 2025, only to resurface as an Executive Vice President at Intel Corporation (NASDAQ: INTC) in October 2025. TSMC's lawsuit contends that this rapid transition, coupled with Lo's deep knowledge of their proprietary processes, creates a "high probability" of trade secret misuse and disclosure. The alleged secrets are not just any data; they encompass the blueprints for TSMC's most advanced and future-defining process nodes—the 2nm, A16, and A14 technologies—which are crucial for the next generation of high-performance computing and AI applications.
TSMC's concerns are exacerbated by Lo's activities prior to his departure. In March 2024, he was reassigned from a direct R&D role to the Corporate Strategy Development department, a position designed to advise the Chairman and CEO. However, TSMC alleges that even in this advisory capacity, Lo continued to actively engage with R&D teams, convening meetings and requesting detailed reports on technologies under development and those planned for future nodes. This sustained engagement, TSMC argues, allowed him to maintain an intimate understanding of the company's most sensitive technological advancements, making his move to a direct competitor particularly problematic.
During his exit interview with TSMC General Counsel Sylvia Fang on July 22, 2025, Lo reportedly stated his intention to join an academic institution, making no mention of his impending move to Intel. This alleged misrepresentation further strengthens TSMC's claim of non-compete agreement violations, alongside breaches of Taiwan's stringent Trade Secrets Act. The legal action is not merely about a single executive; it is a battle for the very intellectual capital that defines leadership in the intensely competitive semiconductor fabrication space.
Initial reactions from the AI research community and industry experts highlight the gravity of the situation. Many see this as a test case for intellectual property protection in an era of rapid technological convergence and heightened geopolitical tensions.
