Objective quantitative Chinese invention patent evaluation system and method

Abstract

The invention provides an objective quantitative Chinese invention patent evaluation system and method. The method comprises a patent information database, an algorithm program, a function module andthe like, wherein an evaluation method is embodied in the algorithm program, and specifically data cleaning comprises the steps of complementing or removing data in which some data is missing, unifying duplicate data and converting fields with wrong fields; data information extracting comprises the steps of extracting key information and calculating time interval, quantifying text information suchas abstracts, specifications and the like and extracting discrete ordered fields and unordered type field information; data re-planning comprises the steps of re-assigning new values to the extractedinformation. A model building module includes variable selection and model optimization. A patent evaluation module includes IPV scores, percentage grades, patent rating, life expectancy estimate, rating of patent subjects and the like. Through model calculation, intangible intellectual property evaluation is quantified and objectiveized, the interference of human factors is eliminated, the blankof programmatic patent evaluation is filled, and the method is real and reliable.

Description

Technical field [0001] The present invention relates to intellectual property evaluation technology, and is an objective and quantitative Chinese invention patent evaluation system and method based on statistics and data mining models to evaluate intellectual property rights. Background technique [0002] At present, patent rights play a vital role in today's business activities. In the investment field, it encourages investors to enter emerging industries and take the lead in seizing the market before competitors act. In market competition, it can effectively protect its own innovative technologies, avoid unnecessary disputes, and enhance its competitive advantage in the industry; in terms of strategic layout, patent rights are essential for identifying the development direction and economic trend of the industry and formulating appropriate patent strategies The layout also plays an important role. [0003] Both the value of the patent right and the derivative value of the paten...

Problems solved by technology

Patent value evaluation is the most intuitive price reflection in patent evaluation, that is, to realize the evaluation based on the methods of intangible asset evaluation in accounting (such as income method, cost method, market method) to solve the problem of how much the patent is worth in patent transactions. The problem is often seen in the patent (intangible asset) valuation reports of accountants and asset valuers. However, using the three basic valuation methods cannot accurately price patents
