First, the reason why the patent is invalid. Therefore, the applied patents are all applicable to the service life, and if they exceed the time limit stipulated by the national patent law, they will become invalid patents. If the patentee terminates the patent right early, it will also lead to the invalidation of the patent. For example, the patent owner fails to pay the corresponding fees in accordance with the relevant regulations, or the patent owner provides a written statement to the relevant institutions to abandon the patent, and the patent will become invalid. At the same time, the patent applicant has successfully submitted the patent-related application, but if the patent acquisition is abandoned due to related factors, the patent will also be invalid.
Second, the benefits of applying for a patent. Patents can effectively protect inventions and creations in law. And after applying for a patent, the invented product or service can be protected by law as a kind of property right, and the product inventor after applying for a patent enjoys the independent possession of the enterprise. The appearance of patents can also improve the enthusiasm of the masses for invention and creation, and play a positive role in promoting the development of national science and technology. At the same time, patented inventions will be made public to the whole society, which is also conducive to avoiding repeated research on similar or identical technologies. From this clever point of view, it has also promoted the development of the national science and technology industry.
Third, the patent type and patent application process. Patents can be divided into three types: invention patents, utility model patents and design patents. According to different situations, you can apply for different patents. Inventors can apply for a patent in China National Intellectual Property Administration with relevant certification materials, and they can also apply for a patent by relying on relevant institutions. After the relevant materials are submitted to China National Intellectual Property Administration, the patent certification documents can be obtained after the preliminary examination in China National Intellectual Property Administration and the relevant patent application fees are paid.
