Why LawMay

Four Reasons Clients Don’t Leave

01

Bilingual Working Practice

We practice on both sides of the Pacific and work natively in English and Chinese — from the first client call to the federal courtroom, with no translation loss and no cultural mismatch. Your facts and your position reach the judge intact.

02

Federal Litigation

Schedule A mass litigation, emergency TRO dissolution, ITC Section 337 — the toughest federal battlegrounds for cross-border sellers are where we appear routinely, not occasionally.

03

Dual US–China Qualification

California, New York, and Washington attorneys; USPTO trademark attorneys; PRC lawyers and patent attorneys — one team holding both U.S. and Chinese credentials, so cross-border matters never get handed off between two sets of lawyers.

04

Deep, Not Wide

We are not a do-everything firm. We go deep in cross-border IP and dispute resolution, and nothing else. In high-stakes matters, the certainty of specialization beats the comfort of big-and-broad.
