US Sanctions Five Chinese Entities Under PAIPA in Trade Secrets Case

KEY FACTS

  • The US State Department announced sanctions on five Chinese entities on October 20 under the Protecting American Intellectual Property Act.
  • The sanctioned parties include Shanghai Zhisuan Technology founded by Ding Linwei, Miracle Plus, and three affiliated entities.
  • In January, a federal jury convicted Ding Linwei on seven counts of trade secret theft.
  • A federal judge subsequently acquitted him on seven economic espionage charges, citing insufficient evidence.
  • The trade secret theft convictions remain valid and were not overturned.

PHYSIX OBSERVATION

By escalating a civil trade secrets case into administrative sanctions, the US is weaponizing intellectual property enforcement tools. For domestic AI entrepreneurs, collaborating with technical personnel who have overseas backgrounds or accepting USD fund investments could trigger compliance risks. The signal is clear: technological decoupling is extending from chips to talent and capital.
