What is that function of patent document? How to use patent documents? Many patentees do not know the function and value of patent documents when applying for patents. Patent documents are very important to the patentee. Without patent documents, the patentee is like a headless fly who doesn't know the direction of patent application. What should they pay attention to without knowing the patent application? If you need to apply for a patent through repeated patent inspection, it is easy to fail to apply for such a patent. How to use patent documents A patent document is a document that records all kinds of relevant documents produced in the process of patent application, examination and approval. Patent documents in a narrow sense refer to patent application specifications including patent claims, specifications, claims and abstracts, as well as documents and materials of recognized patent specifications. Patent literature in a broad sense also includes patent bulletins, patent abstracts, various search indexes and reference books. Patent literature is a kind of literature that integrates technical, economic and legal information. Patent literature is conducive to the technological development of enterprises, can be used as a powerful basis for patent litigation, and is conducive to the introduction of foreign advanced technology and equipment; Before applying for a patent, the applicant should search the relevant patent literature to find out whether the invention is duplicated by other existing technologies. In order to avoid obtaining 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. In addition to the above, we can also learn about the latest development of science and technology through the role of patent documents. From the lessons of previous enterprise technology development, many enterprises blindly develop some new products, which not only causes waste of manpower, material resources and financial resources, but also shows the actual creativity of patents by comparing with previous technologies; Therefore, most of the functions of patent documents can bring a lot of reference value to the patentee, and only by standing on the shoulders of previous research and development can we see further.
