What are the licensing conditions for invention patents?

Legal analysis: the authorization condition of invention patent is that the invention must be novel, creative and practical. Only when these three basic requirements are met at the same time can the invention be granted a patent right. As for novelty, creativity and practicality, there are also corresponding judgment methods. For example, it is already known to the public before applying for a patent, so a patent cannot be granted.

Legal basis: Article 42 of the Patent Law of People's Republic of China (PRC) has a term of 20 years, and the term of utility model patent and design patent is 10 years, counting from the date of filing. The term of the utility model patent is 10 year, counting from the date of application. The termination of patent right can be divided into:

(2) Termination without payment: If the patentee fails to pay or pay all the annual fees and late fees in accordance with regulations, the patent right shall be terminated as of the expiration date of the previous year.
