How to protect China's successful utility model patent abroad? What is the difference between the PCT application of the Intellectual Property Office and the patent application directly abroad?

First, patent protection is regional, and it will be protected in any country where it is applied. Therefore, a successful patent application in China can only be protected in China. To be protected in a foreign country, you must also apply for a patent in that country.

Two, there are two ways to apply for a patent in a foreign country, that is, through the application, or directly to the intellectual property office of the country to apply first. The main difference is that by applying for a patent, China applicants can submit an international patent application to the Patent Office in only one language, so they can apply for a patent in many countries instead of submitting a patent application to each country alone, which provides convenience for patent applicants to apply for a patent abroad.
