According to the Patent Law of China, an applicant for a foreign patent should file a patent application with the Chinese Patent Office before applying for a foreign patent. This is a necessary condition for applying for any international patent. This is also a kind of protection for China's patent. So what are the application requirements of PCT international patent application? Let's take a look. What are the application requirements of PCT international patent application? According to the patent cooperation treaty, international patent application is also called PCT international application. When an applicant submits an international application, he can request the protection of his invention and creation in all member countries of the treaty at the same time. This application has the effect of a formal national application in a designated country from the date of international application. Determining the international filing date should meet the minimum requirements stipulated in Article 1 1 of the Treaty. The date of the international application shall be determined according to the date when the receiving office receives the patent application documents. If priority is required, the applicant needs to fill in the priority information in the application and submit a priority copy to the acceptance bureau or the international bureau within 16 months from the earliest priority date. If the earlier application is submitted to the acceptance bureau, the applicant may request the acceptance bureau to prepare and submit the priority document to the International Bureau. The priority may be modified or increased within 16 months from the earliest priority date, or within 4 months from the date of international application (whichever is later). The claim can be resumed in the international phase, that is, if the international application is filed after the priority date of 65438+February and within1April, the application for resumption of priority can be submitted and the application fee for resumption of priority can be paid, and the claim in the international phase can be established (only some acceptance bureaus recognize the above terms). After entering the national stage, many member States refused to recognize the restoration. In China, the priority of restoration in the international phase was confirmed only after the application entered the national phase. In the international stage, there is no distinction between types of protection, that is, the applicant automatically specifies each type of industrial property protection when submitting an international application. When the patent application enters the national stage, the applicant can choose the protection type according to the patent law of each country or region. To submit an application to the Chinese Patent Office, the following requirements shall be met: at least one applicant has the nationality or residence of China; The international application is written in Chinese or English; Instructions submitted as an international application (printed in the printed request form); The name of the applicant, as long as the identity of the applicant can be confirmed; A handbook; Claim.
