Yes, you can apply for a PCT application through the National Patent Office.
Benefits of applying for PCT:
1. You only need to submit one international patent application to apply for patents in multiple countries, instead of having to submit patent applications to each country separately. It provides convenience for patent applicants to apply for patents in foreign countries;
2. When a foreign country files an ordinary patent application, the patent applicant must apply to the patent office of each country within twelve months after the date of first filing the patent application. Submit a patent application. Through the PCT, a patent applicant can go through the procedures for entering an international patent application into each country within twenty months after the first submission of a patent application; if an international preliminary examination is requested, it can also be done thirty months after the first submission of a patent application. The procedures for international patent applications to enter each country will be handled within months. This extends the time required to enter the national phase. Using this period of time, the patent applicant can investigate the market, the commercial prospects of the invention, and other factors, and decide whether to continue applying for a foreign patent before spending a large amount of money to enter the national phase. If, after investigation, you decide not to apply for a patent abroad, you can save costs.
3. International patent applications must go through an international search by an international search authority and obtain a high-quality international search report. The international search report provides one or more prior art documents, allowing the patent applicant to not only understand the status of the prior art, but also to make a preliminary judgment on whether the invention has the prospect of being patented. If the international application has passed the international preliminary examination, the patent applicant can also obtain a high-standard international preliminary examination report issued by the international preliminary examination unit. If the international preliminary examination report shows that the invention does not have novelty, inventiveness and industrial applicability, the patent applicant may consider not entering the national phase in order to save costs; if the international preliminary examination report shows that the invention has novelty . Inventiveness and industrial applicability, the patent applicant is likely to obtain a "strong" patent and consider entering the national stage.
Fourth, the patent application fee only needs to be paid to the receiving office instead of to the patent offices of all countries that require patent protection, which simplifies the payment procedures.
5. The national fees for international patent applications in some countries are lower than those for ordinary applications.
6. The language of international patent application can be Chinese, English, French, German, Japanese, Russian, Spanish, etc.
Chinese applicants can submit international patent applications in Chinese and English, which provides convenience for Chinese foreign-invested enterprises to apply for patents.
