Where can I find legal-status information on Chinese patents in English?

You can find English legal status information on Chinese invention patents free of charge in the EPO’s Espacenet database and SIPO’s Patent Search and Service System.

Note: There is a time delay of three months for legal status information in English in Espacenet. You should therefore cross-check your results with the corresponding information in Chinese. You can find a step-by-step guide on how to do a legal status search in Chinese on our website.
