There are three ways for the Patent Office to deliver notices or documents, namely by mail, in person delivery and by public announcement.
The first mailing method is the most commonly used. The recipient here can be the applicant himself. If the applicant entrusts a patent agency, the document will not be sent to the applicant, but to the relevant agent of the agency. If the patent application is filed jointly by two or more persons, the Patent Office will send the relevant documents to the first signatory in the request (a representative of all applicants who is also an applicant). . ?
The second way is to deliver it in person. For example, when an applicant submits a patent application in person, the Patent Office will send the acceptance notice to the applicant in person. Another option is for the parties to come to the Patent Office in person to collect priority certification documents, etc., and the Patent Office will deliver the documents to the parties in person. ?
The third method is used when the recipient's address is unclear and the document cannot be delivered to the party by mail. That is, the Patent Office publishes relevant notices in the regularly published Patent Gazette. One month has passed since the date of the announcement of the notice, regardless of whether the recipient has actually read the notice, it will be deemed to have been sent, and the relevant period specified in the document will begin to run. Therefore, applicants are reminded that when the applicant's address changes, they must promptly go through the procedures for changing the bibliographic items---the above answers are compiled and provided by Jialu.com
