Patent right mainly has the characteristics of exclusiveness, timeliness and regionality.
(1) exclusivity
The patentee enjoys exclusive or exclusive rights to the patent right he owns, and no one may use it without his permission or under special circumstances stipulated by law.
(2) timeliness
Timeliness means that the protection of the patentee by law is limited. After this time limit, it will no longer be protected and anyone can use it.
(3) regionality
Regionality means that the patent rights obtained according to the laws of one country are only protected by law in that country, but not in other countries, unless there is a bilateral patent (intellectual property) protection agreement between the two countries.
