What are the circumstances of patent application withdrawal? 1. The applicant's voluntary withdrawal of the patent application shall be made before the patent office makes public (announces). This is because, if the declaration of voluntary withdrawal of the patent application is made after the Patent Office has made preparations for publishing the patent application documents, the application documents will still be published. It should also be noted that once the request for voluntary withdrawal of a patent application is made, it may not be possible to request recovery, so a voluntary withdrawal statement must be made carefully. 2. The patent is deemed to have been withdrawn (1). If the applicant fails to submit a request for substantive examination to the state patent administration department within three years from the date of application, the application shall be deemed to have been withdrawn. (2) After substantive examination, the Patent Office requires the applicant to state his opinions or amend the application within a specified time limit, and if the applicant fails to reply within the time limit without justifiable reasons, the application shall be deemed to have been withdrawn. (3) If the annual fee is not paid in accordance with the regulations, the patent right shall be terminated before the expiration of the time limit. The patentee shall pay the annual fee from the year when the patent right is granted. What are the circumstances of patent application withdrawal?
