What are the procedures for international pct patent application?

The details of the Pct application process are as follows: What is the Patent Cooperation Treaty (PCT)? PCT is an international treaty concluded by many member countries of Paris Convention 125 and managed by WIPO. Through PCT, applicants can apply for invention patent protection in every country in a large number of countries as long as they submit 1 "international" patent application. Patent authorization in the so-called "national stage" is still the responsibility of the national or regional patent office. 2. Submit an application: You can submit an application to the domestic patent office. 3. International search: ISA (one of the major patent offices in the world) searches for published documents, looking for documents that may have an impact on whether the applicant's invention may be granted a patent right. The report will specify the novelty and creativity of each document listed, and express opinions on whether the applicant's invention can be granted a patent right. International publication: the contents of the international application will be published as soon as possible after the earliest application date 18 months expires. V. International Preliminary Examination: "International Preliminary Examination Unit (IPEA)" (one of the major patent offices in the world) usually makes supplementary analysis on the possibility of obtaining a patent for the revised application at the request of the applicant. 6. National stage: After the PCT procedure is completed, the applicant begins to apply directly to the patent office of the country (or region) where he applies for a patent.
