To apply for a patent, the applicant shall submit a written application to the patent administration department of the State Council and submit the required documents. After the applicant files a patent application with the patent administration department of the State Council, the applicant may withdraw the patent application at any time before the patent application is approved. To apply for withdrawing the patent application, a written statement shall be submitted to the patent administration department of the State Council, which shall include the name, application number and application date of the invention-creation for which the patent is applied. After receiving the declaration of the applicant's withdrawal of the patent application, the administrative department for patent in the State Council may make a decision to withdraw the patent application and make an announcement. If the applicant withdraws his patent application after the patent administrative department in the State Council has made the printing preparations for publishing the patent application documents, the patent administrative department in the State Council can still make a decision to withdraw the patent, but the patent application documents submitted by the applicant still need to be published, and the applicant's patent withdrawal statement will be announced in the future patent announcement.
Incidentally, after the patent application is accepted by the patent administration department of the State Council, the patent applicant still has the right to modify the submitted patent documents, but the modification of the application documents for invention patents and utility models shall not exceed the scope recorded in the original specifications and claims, and the modification of the patent documents for design shall not exceed the scope shown in the original pictures or photographs. If it is beyond the prescribed scope, the original patent application shall be withdrawn and a new patent application shall be made.
