Foreign companies and individuals filing patents in China must settle representation, applicant identity, and ownership before translating the technical file. This guide explains when a lawfully established Chinese patent agency is mandatory, why a Chinese subsidiary does not automatically exempt its foreign parent, and how powers of attorney, bilingual applicant names, priority rights, assignments, and corporate records fit together. It also explains CNIPA’s Chinese-translation terminology, how to verify an agency through official records, and where to report unauthorized patent agents. CertOf can prepare translated ownership and corporate documents for agency review but does not provide Chinese patent representation or legal advice.
