FAQ
Must a foreign company use a Chinese agent to file in China?
In almost every case, yes. Applicants without a habitual residence or business office in China must appoint a CNIPA-licensed Chinese agency for trademark and patent filings. That is a legal requirement, not a service preference.
Is PCT an international patent that covers China automatically?
No. PCT is a filing procedure. Protection in China still requires a Chinese national phase, a translation, and examination by CNIPA. Each country decides grant on its own law.
What is a China power of attorney (POA)?
It is the document that appoints the local agency. We send the correct form. Execution formalities (wet-ink, company chop, notarisation) depend on the procedure; we specify them in the instruction email.
A China trademark was refused. Is that the end?
Not necessarily. You may file an appeal against refusal within a short statutory period (often 15 days from receipt of the refusal). Evidence of use, distinctiveness or dissimilarity is usually required. Missing the window abandons the application.
Does a China trademark protect us worldwide?
No. Trademark rights are territorial. A China registration covers mainland China, not Hong Kong, Macao or Taiwan, and not the US, EU or Japan. Use Madrid or national filings for those markets.
How do we choose among invention patents, utility models and designs?
Technical methods and products with a high inventive step usually go to invention patents. Structural product improvements may fit a utility model. Appearance is a design (industrial design). One product can support more than one filing.
We already sold the product. Can we still file a China patent?
Possibly, but novelty is at risk. Public sale, exhibitions and online disclosure can destroy novelty except in narrow grace-period cases. Tell us the first public date before we advise.
Why register copyright if protection is automatic?
Registration is voluntary, but the certificate is widely accepted as preliminary evidence of ownership and date — for platform complaints, licences, customs and financing. It does not replace a trademark for brand protection.
