Patent infringement detection method based on claims

Abstract

The invention relates to a patent infringement detection method based on claims. The patent infringement detection method comprises the following steps of step 1) carrying out data acquisition and preprocessing; 2) expressing the claims as a hierarchical vector matrix; and 3) checking whether the patent is infringement or not according to similarity results calculated according to different levels. According to the patent infringement detection method based on claims, the most important claims in the patent text are used as main research objects; by decomposing the structure of the claims, thesimilarity of each part after decomposition is calculated respectively, and whether the patent to be detected is infringement is finally determined, so that the accuracy of patent infringement detection is effectively improved, the efficiency is high, the detection accuracy is high, the working complexity is reduced, the working efficiency is improved, and the requirements of practical application can be well met.

Description

technical field [0001] The invention belongs to the technical field of text processing, and in particular relates to a claim-based patent infringement detection method. Background technique [0002] With the development of the times, patents, as the carrier of knowledge, have become an important source of knowledge in the fields of science and technology and industry. According to research by the World Intellectual Property Organization, 90% of the latest inventions and innovations are derived from patent documents. Valuable patents tend to be imitated. As the latest technologies or inventions attract the attention of the market, many companies also begin to pay attention to how to apply related technologies to their own products. Therefore, these companies become potential infringers when these products or patents are launched. [0003] Patent infringement is the act of infringing the rights of the patentee, which is endowed by law and legally protected. The principle of...

AI Technical Summary

Problems solved by technology

After summarizing the previous research results, it is found that the research content in the field of patent infringement detection focuses on the key feature word extraction method and the text similarity calculation mechanism, and there is little research on the special structural characteristics of patent texts; in terms of research objects, The research on Chinese patents is still relatively small, and the text vector constructed by extracting keywords from the full text of the patent has a high-dimensional sparse problem. The current similarity calculation method cannot solve this problem well.
