How to apply for a world patent?

Patent applications are divided into domestic patent applications and foreign patent applications. How to apply for a world patent? In fact, world patents refer to international patent applications. There are two ways to apply for an international patent. The first is the Paris Convention, which refers to the way to directly submit a patent application to a country interested in obtaining patent authorization within 12/6 months according to the priority stipulated in the Paris Convention.

During this period, the applicant can make a preliminary assessment of the possibility of obtaining patent authorization for the patent application by using international retrieval and international preliminary examination procedures, and determine whether to apply in a specific country in combination with factors such as technological development and market prospects. Compared with Paris Convention, PCT international application route needs to pay more for the international stage of PCT international application. The submission of PCT international application is equivalent to filing patent applications in all PCT member countries, which provides an opportunity to create conflicting applications and can prevent others from obtaining patents in these countries to some extent. However, the practice of the Paris Convention can hardly produce this effect. The applicant submits an international application that meets the requirements of PCT format in one language and pays a set of fees. International retrieval can be supplemented by International Retrieval Unit (ISA), one of the major patent offices in the world. After the international publication, at the request of the applicant, the international retrieval unit will conduct additional patent analysis. After the PCT procedure is completed, the applicant begins to seek patent authorization directly from the patent office of the country (or region) that wishes to obtain a patent.
