TSMC Files Lawsuit Against Former Executive Wei-Jen Lo Over Trade Secret Concerns

Allegations of Trade Secret Breach
Taiwan Semiconductor Manufacturing Company (TSMC) has initiated legal proceedings against its former Senior Vice President, Wei-Jen Lo, alleging that he may have leaked confidential information to Intel Corporation. The lawsuit, filed on November 25, 2025, in Taiwan's Intellectual Property and Commercial Court, cites violations of Lo's employment contract, a non-compete agreement, and the Trade Secrets Act. TSMC claims there is a "high probability" that Lo will use or disclose its trade secrets to Intel, necessitating legal action.
Lo, who retired from TSMC on July 27, 2025, after a 21-year tenure, joined Intel shortly thereafter as Executive Vice President. TSMC's concerns stem from Lo's actions during his final months at the company, particularly after his reassignment in March 2024 to a corporate strategy role, which did not involve direct oversight of research and development (R&D). Despite this change, TSMC alleges that Lo continued to engage with R&D staff to gather information on technologies under development.
Background and Context
Lo's career at TSMC began in 2004, and he was promoted to Senior Vice President in 2014, playing a pivotal role in the development of advanced semiconductor technologies, including the mass production of 5-nanometer, 3-nanometer, and 2-nanometer chips. Prior to his time at TSMC, Lo worked at Intel for 18 years, where he held various leadership positions, including overseeing technology development.
TSMC's lawsuit follows reports from local media suggesting that Lo may have taken proprietary technology data to Intel, prompting an investigation by Taiwan's High Prosecutors Office. The Taiwanese government is also examining whether Lo's actions constitute violations of national security laws.
Official Statements & Responses
In its statement, TSMC emphasized the necessity of legal action to protect its intellectual property, citing the potential risks posed by Lo's transition to a direct competitor. Taiwan's Ministry of Economic Affairs has expressed its support for TSMC's legal efforts and is closely monitoring the situation's impact on the semiconductor industry.
Intel CEO Lip-Bu Tan has publicly denied any wrongdoing, asserting that Intel respects intellectual property rights. He described the allegations as "rumor and speculation" during a recent industry event.
Criticism & Opposition
While TSMC's lawsuit is a significant move in the competitive semiconductor landscape, it has raised questions about the implications for industry practices regarding employee transitions between rival firms. Critics argue that such legal actions could stifle innovation and collaboration within the sector.
Conflicting Reports & Gaps
There are discrepancies in the reports regarding the specifics of Lo's alleged actions. While TSMC claims he held unauthorized meetings with R&D staff, it has not clarified whether these meetings were sanctioned or how Lo accessed sensitive information. Additionally, prosecutors have yet to file criminal charges against Lo, leaving the legal ramifications uncertain.
What's Next
As the lawsuit progresses, TSMC and Taiwanese authorities will continue to investigate the potential breaches of trade secrets and national security laws. The outcome of this case could have significant ramifications for both TSMC and Intel, as well as the broader semiconductor industry, which is characterized by intense competition and the critical importance of proprietary technology.
