to apply for a patent, you should submit the necessary application documents and pay the fees as required. Patent applications must be handled in written form or electronic application form. The written application documents cannot be replaced or omitted by oral explanation or providing samples or models. In the patent examination and approval procedure, only written documents have legal effect. All kinds of formalities shall be signed in accordance with the provisions, and the signature shall be exactly the same as the name filled in the request. The signature shall not be copied. The procedures involving the transfer of rights shall be signed by all applicants, and other procedures may be handled with the signature of the applicant's representative. If a patent agency is entrusted, it shall be handled with the signature of the patent agency. If the formalities are to be accompanied by supporting documents or attachments, the supporting documents and attachments shall be original or duplicates, and no duplicates shall be used.
