Legal analysis: To apply for a patent for utility model, you must first submit materials to the Intellectual Property Office. The acceptance stage is about one month, the preliminary examination stage is about six months, and the final licensing stage is about two months, totaling about eight months to one year. It will take more than one and a half years for the invention patent to be approved. If it is a patent for appearance or utility model, it can be completed within one year. Utility models and designs shall go through the stages of acceptance, preliminary examination and authorization announcement. Because there is no need for relevant substantive examination, the authorization time for utility models and designs is relatively short, generally in June 6- 10/0.
Legal basis: Article 26, paragraph 1, of the Patent Law of People's Republic of China (PRC), when applying for a patent for utility model, the applicant shall submit the request, specification and its abstract, patent claim, drawings and other relevant documents. The patent application procedure is complicated, so it is generally recommended that the parties entrust a formal professional patent agency to handle it.
