What is the function of patent documents?

The role of patent documents, patent documents are some materials that are applied as the results of research, design, development and test of discoveries, inventions, utility models and industrial designs, so what is the role of patent documents? What is the function of patent documents? 1. Patent search of patent application. Before applying for a patent, the applicant should search the relevant patent documents to see whether the invention is novel, creative and practical, so as to avoid not getting a patent right after applying; When requesting substantive examination, the applicant for a patent for invention shall submit relevant reference materials including patent documents to the Patent Office in accordance with the provisions of the Patent Law. Second, inspire the ideas of invention and creation. There is a saying that stands on the shoulders of giants. Many inventions were developed on the basis of others' inventions, or were inspired and used for reference. Third, you can learn about the latest developments in this field. As mentioned above, the patent document was reported earlier than other documents1; Three years, and there is a process from the birth to the popularization and application of a new technology, with the time difference ranging from several months to decades. Therefore, we can learn about the latest development of science and technology from patent literature. Fourth, it is conducive to technology transfer. When enterprises are looking for new technologies, there are only two ways: first, enterprises take the initiative to attack; Second, the inventor recommended himself. For initiative, a better method is to search patent literature, search out many technologies in this technical field, and then choose the best; For self-recommendation, we should search patent literature to avoid being confused by the inventive features of self-recommendation. Five, conducive to the technological development of enterprises. From the past lessons, many enterprises blindly develop some new products, which not only wastes manpower, material resources and financial resources, but also is not advanced technology compared with the previous technology, resulting in poor sales of their products in the market. Six, is conducive to the introduction of foreign advanced technology and equipment. Judging from the introduction in the past, there are many disadvantages: blind introduction; Not introducing the most advanced technology; Some patents in technology transfer are expired patents, which leads to high technology use fees, and so on. By searching patent literature, we can not only avoid the above disadvantages, but also shop around and find out the advanced technology suitable for the national conditions. Seven, as a strong basis for patent litigation. In patent infringement litigation, when the defendant is accused of infringement, he should search patent literature and consult the plaintiff's patent information and related background technology to avoid losing the case; When the patent applicant refuses to accept the decision made by the Patent Office Reexamination Board (rejection, revocation, invalidation or maintenance, etc.). ) and bring a suit in a people's court, it shall also search patent literature and provide relevant information.
