How is the validity period stipulated when a patent is infringed?

How is the validity period stipulated when a patent is infringed? There are many problems that should be paid attention to in patent infringement, and the validity period of patent is one of them. So how does patent infringement stipulate the validity period of a patent? How is the validity period of a patent stipulated when it is infringed? The validity period of the patent right is 1, and whether the patent right exceeds the protection period. The protection period of invention patents is 20 years, and the protection period of utility model patents and design patents is 10 year. The patent protection period starts from the date of application, not from the date of granting the patent right. In the case of invention patents, the patentee may be required to pay an appropriate fee from the date of patent announcement to the date of patent grant. It can be seen that at this stage, the implementer does not constitute patent infringement, and if it does, it is not a question of paying appropriate fees, but a question of compensation. It can also be seen that at this stage, utility model and design patents are not protected by patent law. As the obligee, we can consider some protection through trade secrets and copyrights. 2. Does the patentee pay an annual fee? The patentee shall pay an annual fee. If the patentee doesn't pay the annual fee, the patent right will be lost. However, if the patent is paid within six months after the expiration of the patent payment period, the patent right is still valid. Pay attention to the payment time specified in the patent certificate. 3. Does the patentee transfer the patent right? If the infringement occurred before the transfer, the original patentee still has the right to file a lawsuit during the limitation of action. 4. Whether the utility model patent and the design patent have obtained the patent right evaluation report. Where a patent infringement dispute involves a patent for utility model or a patent for design, the people's court or the patent administrative department may require the patentee or interested party to issue a patent evaluation report made by the patent administrative department of the State Council after searching, analyzing and evaluating the relevant utility model or design as evidence for hearing and handling the patent infringement dispute.
