1. (1) The patent claim shall clearly and concisely define the scope of patent protection based on the specification. (2) The written request shall specify the name of the invention or utility model, the name of the inventor, the name and address of the applicant and other matters. (3) The specification shall give a clear and complete description of the invention or utility model, which shall be subject to the realization of the technical personnel in the technical field; If necessary, drawings shall be attached. The technical points of the invention or utility model shall be briefly explained.
2. If it is an application for a patent for invention-creation, the applicant shall specify the direct source and original source of genetic resources in the patent application documents; If the applicant cannot explain the original source, it shall explain the specific reasons. According to Article 42 of the Patent Law of People's Republic of China (PRC), the term of the invention patent right is 20 years, and the term of the utility model patent right and the design patent right is 10 years, all of which are counted from the date of application. The term of invention patent right is 20 years, and the term of utility model patent right and design patent right is 10 years, counting from the date of application. After the expiration of the patent right, the patent right shall be terminated. Before the expiration of the patent right, the patentee may declare in writing that he will give up the patent right.
3. According to Article 44 of the Patent Law, in any of the following circumstances, the patent right shall be terminated before the expiration of the time limit: (1) Failure to pay the annual fee as required. (2) The patentee waives his patent right in writing. When these two situations happen, the patent terminates, and there is a third situation, that is, the patent expires, the patent terminates, and the protection naturally terminates. It can be seen that in most cases, for patents, the term of patent protection is calculated from the date of application, and the specific application situation sometimes changes according to personal circumstances. The protection period of patent is shorter than that of patent right at first. Sometimes the start date is the announcement date of patent authorization, and the end date depends on the patentee, but the longest time is until the end date of patent term.
