The lack of a license in rural areas means that the patent user cannot use the patent.
The reasons for not having the right to use the patent certificate are:
1. The patent usage certificate has expired
2. The patent annual fee has not been paid
3. Unpaid patent royalties. Patent rights are a kind of property right. Therefore, anyone who wants to implement the patent rights must pay patent royalties to the patentee. Of course, in practice, there are also cases where the patentee does not charge royalties through cross-licensing with others.
