There are two ways to withdraw. The first is the so-called deemed withdrawal, which means giving up the patent application by taking no action, such as not paying the application fee, not making corrections, and not stating opinions. Another way to abandon a patent application is to withdraw it voluntarily. The request for abandonment is voluntarily stated in the form of a statement of opinion. The content is very brief. Negotiate the application number and then say: The applicant can withdraw this patent application. Note that all applicants must sign or sign.
