Embodiment 1

[0032] Example 1: Based on a certain patent P 1 As an example, as a patent to be evaluated, according to the method of the present invention, the patent P 1 value is evaluated. For patent P 1 The value assessment method process is as follows figure 1 shown.

[0033] Based on the Derwent patent database DWPI, the patentees, citing patentees, cited patentees, patent family counts, citations, average patent citation rate of patentees, average patentees of patentees Search and analyze the citation rate and the average patent family of the patentee. In this example, α 1 、α 2 、α3 、α 4 、α 5 Respectively, the company size, the number of patent applications of the company, the average citation rate of the company's patents, the average citation rate of the company's patents, and the weight value of the company's international market competitiveness to the company's strength; set the weight coefficient α 1 =0.1, α 2 =0.15, α 3 =0.3, α 4 =0.25, α 5 =0.2. beta 1 , β 2 , β ...

Abstract

The invention discloses a patent value assessment method. The influences on the patent value from the strength value of a patentee company and the technical competitiveness value of a patent to be assessed are considered respectively, and then weighted summation is carried out; when the strength value of the patentee company is calculated, the factors of the company scale value, the application number of patents of the company, the average cited rate of the patents of the company, the average citing rate of the patents of the company, the average same-class patent number of the patents of the company and the like are included; the strength of the company owning the patent right of the patent citing the patent to be assessed and the strength of the company owning the patent right of the patient cited by the assessed patent are considered; when the technical competitiveness value of the patent to be assessed is calculated, the number of the cited patients by the patient to be assessed, the number of times of being cited by patents and the number of same-class patents of the patient to be assessed are considered. Comprehensive and accurate searching based on the DWPI database is carried out, the value of each patent in the DWPI database can be calculated, high effectiveness is obtained, and the patent value assessment method can be applied to assessment of patent value.

Description

technical field [0001] The invention belongs to a value prediction processing method, and in particular relates to a patent value evaluation technology. Background technique [0002] Traditional patent value evaluation methods mainly include cost method, market method, income method, discounted cash flow method and option method. The cost method is based on the current market price, and the cost of creating or purchasing a similar patented technology is used to evaluate the expected future income of the proprietary technology. The market method refers to the evaluation method of direct comparison or analogy analysis with reference to the prices of the patents that are the same or similar to the evaluated objects in the market, and is used to evaluate the patent value of listed companies. The income method discounts the future income of the evaluation object at a certain discount rate, and accumulates the evaluation method of the present value on the base date, which is used...
