According to the PCT, an applicant from China filed an international patent application in Chinese in China, and he can get the foreign priority recognized by more than 0/00 member countries all over the world.
Although PCT covers the whole world, this procedure simplifies the application procedure, prolongs the time for application documents to enter other countries, saves costs, and effectively prevents relevant international markets from being occupied by other enterprises.
The most important thing is to give applicants more time to investigate whether the potential international market has the value of applying for a patent, and to provide bargaining chips for international technology trade.
2. Compound application Some inventions have multiple technical features, so you can apply for two or three different types of patents at the same time.
For example, a product with a new structure also has a novel and beautiful appearance, which means that you can apply for an invention patent and an appearance patent at the same time, while protecting the structure, composition and appearance of the product.
If this product also has new composite ingredients, you can also consider applying for a new patent at the same time, while protecting the structure, composition and appearance of the product.
Compound application is not suitable for all patents, but if you want to develop your own patents in an all-round way, it is very worth considering from the time and scope of protection.

Application for domestic priority Domestic priority means that an applicant in China can file a patent application with the State Patent Office again within 65,438+0 years after he first filed a patent application in China, during which no one else's first application can compete with the priority.
