1, patent claim analysis:
Patent claim is the most important part of patent literature, which describes the technical scope of patent, including what technology is protected by patent. Therefore, the technical scope of this patent can be determined by carefully analyzing and understanding each of the patent claims.
2. Analysis of patent specification:
Patent specification is a part that describes and explains the patented technology in detail, including technical background, technical scheme, implementation mode and other information. By analyzing this information in the patent specification, we can further determine the technical scope of the patent.
3. Comparative analysis:
Compare and analyze the target patent with other patents in the same field to understand the technical characteristics and advantages of the target patent and determine its technical scope.
4, refer to the patent classification number:
Patent classification number is the standard used by professional institutions to classify and index patent documents. According to the patent classification number, we can know the scope of the technical field to which the patent belongs.
To sum up, the above methods can help determine the technical scope of patent documents and provide reference for technology research and development and intellectual property protection.
Brief introduction of patent literature:
Patent documents are documents that record all kinds of relevant documents produced in the process of patent application, examination and approval.
Detailed introduction:
1. Patent documents in a narrow sense refer to patent application specifications including patent claims, specifications, claims and abstracts, and documents of recognized patent specifications.
2. Patent documents in a broad sense also include patent bulletins, patent abstracts, various search indexes and reference books. Patent literature is a kind of literature that integrates technical, economic and legal information. Its carrier forms are generally paper, microfilm, magnetic tape, optical disk and so on.
Classification of patent documents:
Patent application disclosure specification and patent authorization announcement specification can be divided into two categories. Patent literature retrieval can be carried out in the following ways: patent retrieval, avoiding infringement retrieval, patent status retrieval, technology prediction retrieval and specific technical scheme retrieval.
Because patents can be divided into invention patents, utility model patents, design patents, service patents, re-announcement patents, defensive announcements, trademarks, technical know-how, etc. Patent documents can also be divided into the above types according to their contents. Patent documents in a broad sense include patent applications, patent specifications, patent announcements, patent legal documents and patent retrieval tools.
