How to submit patent application documents

(2) A form can only be used for one patent application. (3) All documents submitted to the Patent Office shall be kept by the applicant, so as to ensure the consistency of document filling in the process of application examination and approval, and can be used as a reference when replying to the examination opinions. (4) If the application documents are sent by post, a registered letter shall be used. If you can't send it by registered mail, you can use express mail instead of parcel. In addition to indicating the detailed address of the Patent Office or its agency (including postal code), the registered letter should also indicate the words "application documents", "China National Intellectual Property Administration Patent Office accepted" or "China National Intellectual Property Administration Patent Office accepted".
