The first mailing method is the most commonly used method. The recipient here can be the applicant himself. If the applicant entrusts a patent agency, the documents shall not be sent to the applicant, but to the relevant agent of the agency. If two or more people apply for a patent at the same time, the Patent Office will send the relevant documents to the first signatory in the request (representatives of all applicants, who are themselves applicants). ?
The second one was delivered in person. For example, when the applicant submits a patent application in person, the Patent Office will personally send the acceptance notice to the applicant. Then, the parties come to the patent office to get the priority certificate in person, and the patent office personally delivers the documents to the parties. ?
The third way is when the recipient's address is unclear and cannot be mailed to the party concerned. That is, the Patent Office publishes relevant notices in the periodical Patent Bulletin. One month after the announcement of the notice, regardless of whether the recipient actually read the notice of the announcement, it is deemed to have been delivered, and the relevant period specified in the document begins to calculate. So remind the applicant that when the applicant's address changes, it is necessary to go through the formalities of changing the description item in time-the above answer is provided by Jiafa. com.
