Can the patent rejection defense be resumed after the time limit?

Legal analysis: if there is no reply after the expiration of the patent rejection period, it can be regarded as withdrawal of the application. If the applicant can resume the application, he shall consult the patent administration department. Rejecting a patent application is a decision to reject a patent application that does not conform to the provisions of the patent law and not to grant a patent.

Legal basis: Article 35 of the Patent Law of People's Republic of China (PRC). Within three years from the date of filing, the administrative department for patent in the State Council may, upon the request of the applicant at any time, make a substantive examination of the application. If the applicant fails to request substantive examination within the time limit without justifiable reasons, the application shall be deemed to have been withdrawn. The patent administrative department of the State Council may, when it deems it necessary, examine the application for a patent for invention on its own.
