Taiwan prosecutes Chinese chip firm that hired engineers through an unlicensed office
Taipei prosecutors on 1 October indicted Lin Hao-yuan, who ran the Taipei office of Hefei-based Lontium Semiconductor, and sought an 18-month prison sentence. The company allegedly employed Taiwanese engineers through an unlicensed office and earned more than 191 million Taiwan dollars.
According to the Taipei Times and Focus Taiwan, the charge rests on Article 40-1 of the law governing relations between Taiwan and China. This article bars Chinese companies from doing business in Taiwan without permission. Lontium opened an office in Taipei's Neihu district in 2012 and closed it in January 2015, and the Ministry of Economic Affairs approved the closure. Prosecutors say company chairman Chen Feng had Lin rent a new office in Zhongshan district in July 2024 and used it as a Taiwan base.
According to Taiwan News, the company hired local engineers during this period for chip research and development, testing and technical services. Its customers include Quanta Computer, Advantech and Chicony Electronics. Prosecutors issued an arrest warrant for Chen Feng and seized Lin's salary and bonuses. The office had been searched in July 2025. Lontium is one of 16 Chinese technology companies investigated by the Investigation Bureau in summer 2025.
The case shows Taiwan trying to stem talent drain through employment and company registration law rather than export controls. As of 1 October, no information had been released on the stage of prosecution for the remaining 15 of the 16 companies; this could not be verified.
Talay assessment
Bottom line
The 18-month sentence sought may look like a minor case on its own, but it is one of the first concrete indictments from the 16-company investigation. Taiwan now also closely monitors the flow of chip know-how to China through engineer hiring and company registration. The most likely path is similar indictments against the remaining companies within a few months.
Likely effects
- Talent flowsPositive1–6 months
The cost for Chinese chip design firms of employing engineers through covert offices in Taiwan is rising. The 18-month sentence sought could set a deterrent precedent.
- Taiwanese electronics makersNegative1–6 months
Customers such as Quanta, Advantech and Chicony face closer compliance scrutiny of their ties with Chinese suppliers.
- Cross-strait tensionUncertainWeeks
Beijing may present such cases as economic coercion, but no official Chinese response could be found as of 1 October.
