One: Different ideas.
Pct is one of the most commonly used methods to apply for international patent, which is the English abbreviation of patent cooperation treaty. Patents generally refer to domestic invention patents, utility model patents and design patents.
Two: the time is different.
Pct patent application takes at least 18 months, and the specific time will depend on the specific patent and the applicant country. It usually takes about 2-3 years for the invention patent to be examined in substance. The patent of utility model takes about 8- 12 months. The design patent takes about 4-6 months.
Third, auditing and charging are different.
Pct examination, according to the Paris Convention, within 12 months after the national patent application is filed, you can claim priority by applying to other different countries. This is because the patent laws of different countries are different. When applying for pct patent, there will be the following problems: multi-language, multi-form request, multiple retrieval, multiple disclosure and multiple re-examination request. Finally, due to litigation reasons, it needs 12 months of cost difference, national fees and translation fees. General patent examination is completed by the State Patent Office in accordance with domestic patent examination procedures. The utility model patent and the design patent go through several stages: acceptance, examination, authorization and authentication. Invention goes through several stages: acceptance, preliminary examination, substantive examination, authorization and authentication. The application fee is usually several hundred to several thousand yuan.
Four: the process is different
Pct patent application must go through the national stage and the international stage. First apply to the State Patent Office, and then the State Patent Office applies for an international patent through pct. Pct patent application, international search and first-class international preliminary examination will be completed in the international stage. Whether to grant the patent right is decided by the patent office of the designated country, and whether to authorize it.
