Validity of patent authorization in China

From the relevant laws and regulations of our country, we can know that the patent authorization in our country has a time limit. Among them, the invention patent has the longest validity period, which can reach 20 years. After this period, the utility model patent is valid for 10 year. The validity period of the design patent is the same as that of the new model standard, and it is also ten years. The period of validity shall be calculated from the time of patent application. Under some special reasons, the validity of patent authorization will be terminated early. The first is that the patentee fails to pay the annual fee within the specified time according to the relevant regulations. If no obligee continues to pay the fee, the protection of the patent right will be terminated. In the second case, the holder of the patent right voluntarily gives up the patent right and automatically gives up the patent protection. The protection of patent right is not automatically produced when the patent is produced. It is necessary for the obligee to submit an application for patent protection to China Intellectual Property Patent Office. After examination by the Patent Office, the obligee will obtain a legal patent right, and its patent will be protected by law in China. Patent applications are generally entrusted to patent agencies, which can shorten the application time. Applicants need to provide relevant application materials to the agency. On the basis of the application fee, the applicant has to pay some agency fees. After submitting an application for patent Bohu, the State Patent Office will conduct a legal review of the patent application. After passing the examination, the patent right of the obligee will be protected by law. Of course, in the process of the exam, the exam may not pass. Therefore, whether the submitted application materials are qualified is also very important. The patent right of the obligee protected by patent is protected by law. Therefore, the patent at this time is exclusive to the obligee and cannot be illegally infringed by others. Without the authorization of the obligee, no individual may manufacture or sell the patented product of the obligee, and no unit may manufacture or sell the patented product of the obligee. After the expiration of the patent certificate, if the right holder does not continue to apply for patent protection at this time, the right holder's patent will no longer be exclusive, and other people or any unit can manufacture and sell the right holder's patented products. At this time, the patent right is used by others and no longer belongs to infringement.
