Intellectual Property Theft and US Retaliation (Fujian Jinhua Case)

Key Insight

The case of Fujian Jinhua (Jinhua), a Chinese DRAM chipmaker extensively funded by over $5 billion in government capital, exemplifies China's aggressive tactics in acquiring semiconductor manufacturing know-how. Jinhua formed an agreement with Taiwan's UMC, a logic chip fabricator, promising approximately $700 million for DRAM expertise. Subsequently, UMC systematically recruited key personnel from Micron's Taiwan facility, including its president, Steven Chen, and a process manager, J. T. Ho. Kenny Wang, a Micron employee, downloaded 900 confidential files containing Micron's cutting-edge DRAM chip layouts, mask specifications, and test/yield data, transferring them via USB and Google Drive before joining UMC. Micron estimated replicating these secrets would require several years and hundreds of millions of dollars.

Micron alerted Taiwanese prosecutors, who gathered evidence by tapping Wang’s phone and subsequently charged UMC, which had already filed patents based on the purloined technology. When Micron initiated a patent infringement lawsuit against UMC and Jinhua, they retaliated with a countersuit in China's Fujian Province. A Fujian court, described as a 'kangaroo court,' ruled against Micron for violating UMC and Jinhua’s patents—which were derived from Micron's own stolen intellectual property—and consequently banned Micron from selling 26 products in China, its most significant market. This pattern was mirrored in a separate case where a Fujian court swiftly issued a retaliatory preliminary injunction against the American firm Veeco, banning its machinery imports to China, a rare occurrence in Chinese patent cases.

The 'China hawks' on the National Security Council viewed the Micron case as a clear instance of the unfair trade practices President Trump had vowed to address, despite his initial lack of direct interest in Micron. The Trump administration opted against financial sanctions, instead deploying the same export control tool previously used against ZTE. This action severed Jinhua’s access to critical U.S. chip manufacturing equipment, supplied by companies such as Applied Materials, Lam Research, and KLA. Following detailed consultations, Japan, another key producer of advanced equipment, expressed support for the measure. As a direct consequence, Jinhua’s production ground to a halt within months, effectively dismantling China’s most advanced DRAM firm and showcasing the powerful U.S. leverage over essential semiconductor choke points.
