How to apply for foreign-related patents

1. If you need to submit an international patent application, you can apply for a patent in multiple countries without submitting a patent application to each country separately, which provides convenience for patent applicants to apply for a patent abroad. 2. The patent applicant must submit a patent application to the patent offices of various countries within 12 months after the date of filing the patent application for the first time. Through pct, the patent applicant can go through the formalities of international patent application entering each country within 20 months after filing the patent application for the first time; If it is necessary to conduct international preliminary examination, you can also go through the formalities for international patent application to enter various countries within 30 months from the date of filing the patent application for the first time. 3. An international patent application must be searched by an international search agency in order to obtain a high-quality international search report. The international search report gives one or more existing technical documents, so that the patent applicant can not only know the status of the existing technology, but also preliminarily judge whether the invention has the prospect of granting a patent. 4. Only the patent application fee needs to be paid to the acceptance bureau, not to the patent offices of all countries that require patent protection, which simplifies the payment procedures. In some countries, the national cost of international patent application is lower than that of ordinary application. 6. The language of an international patent application can be Chinese, English, French, German, Japanese, Russian, Spanish, etc.
