Abstract

The invention provides a screening and valuing method of a technical similarity patent, comprising an establishing procedure of docking of stereotactic orientation analysis technology and citation networks TSU-CN microstructure, a procedure of establishing a related subnet, and a procedure of collecting monitoring data of internal and external technical flow based on target patent-similar technology-main technology environment, and a procedure of extracting technological spectrum parameters basic data and a procedure of establishing technological spectrum parameters based on a dynamic TSU-CN microstructure. By macroscopic and microcosmic docking of target patent technical flow in similar technology and main technology environment and stereotactic and quantitative control, relative objectivity and accuracy of valuing and screening results are guaranteed. Thus, enterprises are capable of positioning the 'technology value of target patent under the realistic background' reasonably and accurately in the introduction of technology and the development of foreign invalid patents so as to avoid the competitive failure caused by blind technology introduction and patent development. Meantime, the method helps enterprises make competitiveness evaluation on the technical patent in the international similar technology, as well as the option of stock investment.

Description

technical field [0001] The invention belongs to the field of patent technology screening and evaluation, and relates to a screening and evaluation method based on technology similarity patents, which screens and evaluates patent technologies through the TSU microstructure technology spectrum analysis method, and can be applied to enterprises in technology introduction and foreign invalid patents Reasonable and accurate positioning of technical value during development. Background technique [0002] According to the statistical data of the "China Science and Technology Statistical Yearbook" in 2006, the average number of invention patent applications per million yuan of R&D investment in my country's industry is 0.15 per million; the number of patents is large, and only the Chinese Academy of Sciences has an average of 990 invalid patents in the past ten years. Patent profits are low, and there is no obvious correlation between the profits of Chinese enterprises and the number...
