Yi Yi’s practice centers on intellectual property disputes in U.S. federal courts arising from cross-border commercial activity, including patent, trademark, copyright, and unfair competition matters. He advises manufacturers and e-commerce businesses on disputes connected to product delistings, account restrictions, asset restraints, and platform-linked enforcement measures. His work spans multiple federal jurisdictions and often involves early-stage proceedings in which procedural posture materially affects the course of the dispute and related business operations.
At LawMay P.C., he plays a role in shaping the firm’s federal court litigation framework and approach in matters involving emergency relief, declaratory judgment actions, and TRO and preliminary injunction proceedings.
