TSMC sues ex-executive over Intel

TSMC sues ex-executive over Intel

28 November 2025

What happened

TSMC initiated legal action in Taiwan's Intellectual Property and Commercial Court against former Senior Vice President Wei-Jen Lo, alleging trade secret leakage to Intel. Lo, who departed TSMC in July and joined Intel in October, is accused of violating the Trade Secrets Act, employment contract terms, and non-compete agreements. TSMC claims Lo gathered advanced technology information without direct R&D oversight. Taiwanese authorities are investigating, having seized digital devices from Lo's residences.

Why it matters

This incident introduces a significant operational constraint regarding intellectual property protection and employee offboarding protocols. The alleged leakage by a former Senior Vice President, who accessed advanced technology information without direct R&D oversight, increases exposure to trade secret misappropriation. This raises due diligence requirements for compliance, legal, and human resources teams concerning non-compete enforcement, access revocation, and monitoring of departing high-value personnel, particularly those moving to competitors. It also highlights a potential visibility gap in tracking information access by non-R&D roles.
