What is the protection scope of the derivative varieties of new plant variety rights?

Many people may not know much about the right to new plant varieties, so let's first understand what is the right to new plant varieties. The right to new plant varieties is the exclusive right to use, just like the patent right. It refers to the authorization of varieties by units or individuals after the completion of breeding, so that they can enjoy relevant rights and get more protection by law. The new plant variety has several characteristics. First, new varieties must be novel, followed by specificity, stability and proper names. So what is the protection scope of the new variety? Who will protect it? In China, the Forestry Bureau and the Ministry of Agriculture are responsible for the protection of new varieties, and the scope and content of their respective protection are clearly defined in their departmental responsibilities. But now the scope of plant protection in China is basically limited to the propagation materials of plant varieties, which means that the object of protection is not the provinces of plants, but the rights of plant breeders. How long is the protection period of the new variety? The time of different plants is different, mainly depending on the cultivation time of plants. Some plants take a long time to cultivate, so their protection period will be longer. In China, the protection period of some plants is 20 years, and some are 15 years. These 20 years are mainly lianas, ornamental trees, as well as forest trees and fruit trees. How to define the ownership of new varieties? First, distinguish between units and individuals. The main way to distinguish is whether personal research belongs to job-related research. Some people rely on the task of the unit and make use of the material conditions provided by the unit, such as providing funds for research, breeding sites and materials for breeding. Because a lot of information is hard to find, it will take a lot of time, and others can save a lot of time as assistants. For example, technical data are used for new variety research. The second is that under normal circumstances, for this kind of product with exclusive right to use, a contract will generally be signed to determine the ownership according to the contract.
