Taiwan files new charges in TSMC trade secrets case

Taiwanese prosecutors have filed new charges against the Taiwan unit of Tokyo Electron and three others over the alleged theft of trade secrets from TSMC, a major Taiwanese chipmaker.

The additional indictments follow earlier charges in December under the National Security Act and Trade Secrets Act, after a former employee was indicted in August.

If found guilty, Tokyo Electron’s Taiwan unit could face fines of up to T$120 million (US$3.8 million).

The company said the parent firm has not been indicted and the case does not affect its financial results.

🧠 Food for thought

Implications, context, and why it matters.

Enforcement risk outweighs Tokyo Electron’s fine

  • The T$120 million fine barely dents Tokyo Electron, which logged 2024 revenue of 2.43 trillion yen 1. Rising use of Taiwan’s National Security Act means policing across the chip supply chain.
  • Prosecutors say Tokyo Electron Taiwan lacked “concrete preventive or managerial measures” beyond general internal rules 2. Paper policies may not pass without visible safeguards.
  • Tokyo Electron, a Japanese maker of chip-fabrication equipment, sells tools to the chipmaker TSMC in Taiwan 2. If this case starts a pattern of tougher checks, the firm could face limits on operations or tighter audits that strain market access.

Software vendors can close Taiwan’s compliance gap

  • Taiwan used National Security Act (a law used to protect national security and trade secrets in sensitive industries) charges against Tokyo Electron Taiwan for supervisory failures 2. Semiconductor firms face liability for weak controls, creating demand for insider threat detection (software that flags anomalous behavior) and data loss prevention tools (software that blocks moving sensitive files outside approved channels).
  • TSMC sued former executive Wei-Jen Lo over alleged trade secret leaks 2, which puts focus on employee behavior and document control systems (tools that manage access plus sharing of confidential documents).
  • Vendors selling compliance auditing (solutions that test plus document adherence to policies and regulations), secure collaboration platforms (workspaces that share sensitive data with authorized users) plus trade secret protection should prioritize Taiwan’s chip sector 2. Firms must show preventive steps to avoid prosecution under the bar set by this case.
