China implements the system of substantive examination of invention patents, that is, after the first trial is passed, the invention text is made public and substantive examination is carried out within three years. Authorization of legal status means that the patent right has been obtained, while publicity means substantive examination, which is stricter than the first instance. Usually, 50% of inventions are rejected here.
Extended data:
Legal status includes: grant of patent right, patent application right, invalidation of patent right, termination of patent right, restoration of patent right, pledge, preservation and dissolution of patent right, filing of patent license contract, compulsory license for patent exploitation and change of name, nationality and address of patentee.
Patent legal status retrieval refers to patent timeliness and regional retrieval, which can be divided into patent validity retrieval and patent regional retrieval.
Patent validity retrieval refers to the retrieval of the current status of a patent or patent application, with the purpose of knowing whether the patent is valid or not. Patent regional retrieval refers to the retrieval of patents applied for by an invention in those countries and regions, with the purpose of determining the national scope of the patent application.
The legal status of patent is the general situation that the patentee pays attention to when inquiring about patent. Not only will the patentee know the validity period of the patent for other patentees, but he will also know when it will expire, or he needs to know whether the patent is duplicated with others before patent examination.
In addition, there is a very important point: patent trading and patent licensing. The patent fair will be optimistic about the status quo of patents and consider whether to buy certificates. The same is true of patent licensing.
