Legal analysis: patent priority date and application date refer to the date when priority is claimed in the application process, which can be divided into foreign priority and domestic priority; As for the date of application, it is the date when the application documents are submitted to the the State Council department, thus enjoying the patent right. Patent right is generally the right that people who have the fruits of labor will apply for, but the protection period of this right depends on when to apply, and generally depends on whether the patentee chooses the application date or the priority date. These two dates are completely different, so how to implement his own rights depends on how to implement it.
Legal basis: Article 43 of the Patent Law of People's Republic of China (PRC) stipulates that the patentee shall pay the annual fee from the year when the patent right is granted.
