PCT patent refers to the international patent application submitted according to the patent cooperation treaty, and does not refer to the specific patent type. It is not a system for granting patents, but provides a unified application procedure for patent applications among member countries. Through PCT, applicants can submit patent applications to multiple countries or regions at one time, which simplifies the application process and reduces the cost.
In the international phase of PCT, the applicant's patent application will be searched internationally and preliminarily examined to provide reference for its entry into the national phase. PCT patent is mainly a way of international patent application, which helps the applicant to protect his innovation more effectively.
