Can I access the documents in the file of a Chinese patent application?

Yes. The EPO’s Global Dossier includes the office actions in the original language and English translations for Chinese patent applications. It can be accessed via Espacenet and via the European Patent Register.

Furthermore, CNIPA's “China  and Global Patent Examination Information Inquiry” provides online access to this data. Should you have any questions on how to access this source, please contact us.
