Does the patent right have time and national boundaries?

We know that patents are the exclusive rights and interests of patentees, and those who apply for patents will be protected by law. However, the duration of patent protection stipulated by relevant departments is relevant, including some national plans. So is there a time and national boundary limit for patent right? Let's take a look at Bajie's intellectual property rights. Does the patent right have time and national boundaries? Foreign land, sea and air transport vehicles that temporarily pass through China's territory, territorial sea or airspace need to use the machinery, devices and parts that enjoy the patent right in China for their own needs, and do not need the permission of the patentee in China, which does not constitute infringement. According to Article 14 of the Patent Law, the invention patents of state-owned enterprises and institutions that are of great significance to national interests or public interests can be popularized and applied within the approved scope by the relevant competent departments and provincial people's governments in the State Council, allowing designated units to implement them, and the implementing units shall pay royalties to the patentee in accordance with state regulations. Invention patents of collectively-owned units and individuals in China shall be handled with reference to the above provisions. For the patents of foreign patentees, the national plan license is not applicable. In view of the fact that patent right is an intangible property right, which is different from ordinary property right, there is no problem of natural termination of rights due to the disappearance of objects. Therefore, the reasons why patent laws in various countries stipulate the term of patent right are as follows: ① Patent technology itself has the characteristic of gradually losing its property value with the passage of time and the improvement of technical level; (2) The long-term monopoly of patent rights is not conducive to the scientific and technological progress of the whole society and the development of the industry. The term of patent right refers to the legal effective time of patent right. The patent right is protected by law within the validity period. According to the provisions of the patent law, the legal validity of invention patents is 20 years; The legal validity period of utility model patent and design patent is 10 year. The above legal validity period is calculated from the date of application. Does the patent right have time and national boundaries? To sum up, we can clearly know that different patents have different periods of protection, and some countries' plans on patents do not apply to the patents of foreign patentees. If the patentee's exhaustion principle only enjoys exclusive rights to the first sale of patented products.
