Patent classification table is a tool to classify patent documents in various countries. Its basic purpose is to facilitate countries to search when determining the novelty and creativity of patent applications (including evaluating their technological advancement and practical value).
It divides the whole application technology field into several categories, and arranges the list according to the specific principle and symbol system. In this way, users can quickly locate the corresponding technical topics through the patent classification table, thus improving the retrieval efficiency and accuracy.
Patent classification table is the basis of patent application and examination. When applying for a patent, the applicant needs to classify the patent into corresponding categories according to the classification table for subsequent review and authorization. At the same time, the examiner also needs to classify the patent application according to the classification table to ensure the accuracy and fairness of the examination.
The importance of patent classification table lies in that it can make the patent documents of various countries be classified uniformly, which is convenient for retrieval and use, and at the same time provide a basis for patent application and examination, which is helpful to evaluate the technical level and recommend industrial property rights.
Use of patent classification table
1. Organize patent literature: users can easily obtain technical and legal information from it.
2. Selective reporting: as the basis for selective reporting of all users of patent information.
3. Technical level survey: as the basis for investigating the existing technical level in a certain technical field.
4. Recommendation: as the basis for recommending industrial property rights, so as to evaluate the technological development in various fields.
