How we work

Response SLA

We acknowledge instructed email on a China business day, typically within one working day, and flag statutory deadlines the same day we see them.

Channel

Email is the file of record. WeChat is available for time-critical coordination. We do not open a parallel file with your client unless you ask.

Fees

USD (or CNY) quotes per matter. Official fees itemised separately. No published fixed amounts.

Who you will work with

A named bilingual contact on every matter. Patent files sit with Hexinli Patent Agency (CNIPA-registered, agency code 33273). Trademark and copyright files sit with OneWin IP Agency. Complex disputes are coordinated with PRC counsel where a court appearance is required.
