The legal characteristics of patent right are mainly relative to the traditional property ownership, especially the ownership. According to the provisions of the patent law, the legal characteristics of patent rights mainly include three aspects, namely, exclusivity, regionality and timeliness. The intangibility of the object is also an important feature of the patent right, but the intangibility does not belong to the patent right itself, because the intangibility is the feature of all rights. Patent right belongs to absolute right, which is absolute, but it does not belong to its characteristics relative to ownership.
