Under what circumstances is it appropriate to file a PCT international application?

Under what circumstances is it appropriate to file a PCT international application? China has joined the Patent Cooperation Treaty (PCT). Applicants from China can apply for foreign patents from 1 99465438+1October1,and applicants from PCT member countries can also apply for China patents through PCT. When is the appropriate time to submit a PCT international application? An application submitted in the manner specified in PCT is called an international application. Generally speaking, an international application is a patent application filed by a resident or national of a PCT Contracting State to protect several Contracting States. Before China joined the PCT, according to the principles of the Paris Convention, applicants could only file patent applications in foreign countries. After China joined the PCT, the applicant can also use the PCT to file an international application. When the applicant wants to obtain protection from multiple countries for an invention, it is appropriate to use the PCT method. Because through the PCT channel, at the beginning of the application, only one international application needs to be submitted to the Chinese Patent Office, which saves the trouble of submitting national applications to each country separately. Individuals and units in China can still apply to foreign countries in accordance with the principles of the Paris Convention. Especially when the applicant only needs to apply for a patent in one country or several countries, it is appropriate to use the Paris Convention. Under what circumstances is it appropriate to file a PCT international application? The above content simply answers this question.
