Dispute Resolution

Under the leadership of James Jiang, a wellknown practitioner in Chinas compliance and investigation space, Topcom China Law Offices focuses exclusively on government and regulatory matters. The firm advises on compliance governance, trade compliance, antibribery and anticorruption, government investigations and litigation, whitecollar and commercial crime, and crossborder data transfer. 

Based in Shanghai, Jiang leads the firm’s government affairs, compliance, corporate, and litigation practice. He regularly represents clients in highprofile regulatory compliance matters and government investigations. 

Representative matters include acting for ASR Microelectronics Co., Ltd. in an administrative lawsuit that successfully overturned a patent invalidation decision issued by the China National Intellectual Property Administration. The case arose during the client’s IPO process, when competitors initiated multiple patent invalidation and infringement actions to delay the listing. Despite the complexity of the communications and chiprelated technologies involved, the firm overturned the invalidation decision at first instance. The Supreme People’s Court later dismissed the opponent’s appeal and upheld the original judgment. 

The firm also represents Delta Electronics, a global leader in power and thermal management solutions, in a patent infringement dispute before the Shanghai Intellectual Property Court against U.S. company Vicor. Working with U.S. counsel, the team successfully used 28 U.S.C. §1782 to obtain crossborder evidence, including technical and sales data. This is a rare example of §1782 being used in support of China IP litigation and has provided key evidence for the Shanghai proceedings. 

In terms of team growth, Jiayue Long joined the firm from Yuanda Law Firm in January 2025, and Shaoyi Gao joined the IP practice from Dabang Law Firm in February 2025.
