Hongchang "Richard" Deng

I help Chinese manufacturers, Amazon sellers, cross-border e-commerce companies, and technology businesses protect products, brands, online listings, accounts, funds, supply chains, and U.S. market access when intellectual property disputes arise.

I am the Founder and Managing Partner of LawMay P.C., a boutique cross-border intellectual property and litigation firm based in Sacramento, California. I am licensed to practice law in California and China, handle U.S. trademark matters before the United States Patent and Trademark Office, and am also a PRC patent agent.

My practice focuses on U.S. intellectual property litigation and cross-border dispute strategy involving patents, trademarks, copyrights, trade dress, trade secrets, unfair competition, and e-commerce platform enforcement. I represent manufacturers, technology companies, brand owners, and Amazon/e-commerce sellers in federal court litigation, ITC Section 337 investigations, USPTO and TTAB matters, PTAB-related patent disputes, Amazon APEX patent evaluations, TRO/PI disputes, asset-freeze defense, declaratory judgment actions, platform takedowns, account/listing reinstatement, domain name disputes, UDRP/ICANN proceedings, product liability matters, and California Prop. 65 defense.

My work is built around commercially urgent disputes where litigation strategy, platform experience, and bilingual cross-border communication all matter. I have handled matters involving the Central and Northern Districts of California, the Northern District of Illinois, the Western District of Washington, the Eastern, Western, and Southern Districts of Texas, the Southern District of Florida, the Federal Circuit, the Eleventh Circuit, and other U.S. federal courts.

Representative work includes defending Amazon sellers and technology companies in patent, copyright, trademark, and trade dress litigation; responding to Schedule A cases, TROs, asset freezes, default judgments, and platform takedowns; bringing declaratory judgment actions for non-infringement and invalidity; seeking emergency relief to protect accounts, funds, and high-value product listings; handling ITC Section 337 investigations and parallel federal litigation; advising on freedom-to-operate, design-around, licensing, settlement strategy, APEX, TTAB, PTAB, UDRP/ICANN, and IP portfolio strategy.
