The evaluation of patent value is a systematic and complex work, and has the characteristics of strong theories, legality, technicality, timeliness and the like. Generally, the research on the patent value evaluation method involves management, economics, and multiple disciplines such as law and accounting. The existing patent value evaluation system mainly comprises the following 14 evaluation methods and other patent value evaluation methods formed based on the 14 evaluation methods, and specifically comprises the following steps:

1. method of resetting cost

The cost resetting method is called a complete price resetting method or a complete price resetting method, called a cost resetting method for short, and is an evaluation method for re-purchasing or building a brand-new evaluation object under the actual condition and using the difference obtained by subtracting the entity old depreciation, the functional old depreciation and the economic old depreciation of the evaluation object from all the required costs as the actual value of the evaluation object. According to this definition, the basic formula for the reset cost method is: the evaluation value is reset cost-tangible loss-intangible loss.

2. Marketing law

The market method is a method for evaluating the value of an object from the perspective of the market, selecting the trading conditions and prices of a plurality of similar objects in the market as references through market investigation, and combining the trading conditions and the prices according to the characteristics of the objects to be evaluated to consider and adjust the trading conditions and the prices so as to evaluate. It is the most direct assessment method in value assessment.

3. Income method

The income method is also a patent technology value measuring and calculating method for measuring and calculating by using the real asset value, the value mainly referred to when the income method is used for measuring and calculating the patent technology value is the expected income brought by the patent technology in the future development, meanwhile, the current value of various expected income is calculated according to the discounted method, and the current patent value of the patent technology is finally determined.

4. Physical option method

The real option method is a new evaluation and decision-making method developed in recent years, and the method considers the option of a management decision maker in the problem decision of investment, production, product research and development and the like, so that the option value of decision-making in patent implementation can be fully reflected, and the value of the patent technology can be more reasonably and accurately evaluated. In actual physical option evaluation, the value of an evaluation project not only includes the income generated by the project, but also includes the income brought by the option of a decision maker, namely the option value, and the evaluation project is generally assumed to be infinite life, so that a constant differential equation about the option value of the project can be obtained, and the equation is solved to obtain the option value in an analytic form, and the method is considered to be the most complex patent evaluation method.

5. Fuzzy mathematics evaluation method

A fuzzy mathematical evaluation method is based on a fuzzy mathematical theory, firstly, an evaluation index is determined according to contents to be evaluated, then, an analytic hierarchy process is applied, experts are asked to score each evaluation index of a patent, the importance of the index to the patent value is compared pairwise, further, a weight is obtained, a fuzzy matrix is established, value evaluation of the patent value belonging to an established value comment set is obtained, the comment set is quantized, an actual patent value is obtained, the actual patent value is compared with the patent value evaluated by the experts in advance, a deviation is obtained, and finally, the patent value can be represented by the product of the actual patent value and the deviation.

6. AHP assessment model method

AHP assessment model method provides a basic method for representing measure of decision factors (especially social and economic factors).

The method adopts a relative scale form, fully utilizes personal experience and judgment capability, compares the relative importance of related factors of the same level pairwise according to the specified relative scale, namely proportional scale, under a hierarchical structure and by the judgment of a decision maker, and measures the decision target according to a hierarchical synthesis scheme from top to bottom, wherein the final result of the measure is expressed by the weight of the relative importance of the scheme.

7. BP neural network model method

A BP neural network model method is characterized in that the values of patent to be dealt and patent to be deal obey the same distribution, the value of patent to be dealt is known, the value of patent to be dealt is unknown, then patent deal price data of open auction is collected, relevant factors of molecules influencing the patent deal price are simulated through a BP network program, the relation between input variables (relevant factors influencing the patent value) and output results (patent value evaluation values) in a sample is established on the basis, a general model of patent value evaluation is obtained, and then the variable of the patent to be evaluated is substituted into the program, so that the evaluation value of the patent to be evaluated can be obtained.

8. IPScore-based patent value evaluation method

The patent value evaluation method based on IPScore is characterized in that IPScore2.0 software which is a systematic tool for evaluating the value of a patent or a technical project is developed by cooperation of the Danish patent office in 2002 and JanMaturitsen professor of the Copenhagen institute of commerce, and qualitative and quantitative evaluation is carried out in a form of economic prediction reflecting the net current value of the evaluated patent.

The IPScore needs to enter five types of data, namely: a-legal status; b-technical factor; c-market Environment; d-financial index; e-company strategy. Including both quantitative financial and patent data and qualitative questionnaire questions to ensure that the results of the assessment are valid and comprehensive.

9. Patent value fuzzy evaluation method based on analytic hierarchy process

The patent value fuzzy evaluation method based on the analytic hierarchy process comprises the steps of firstly determining the weight of evaluation indexes by using the analytic hierarchy process, then evaluating each index of a patent by using a fuzzy comprehensive evaluation method, and finally obtaining a comprehensive score;

the idea of the analytic hierarchy process is as follows: and determining the quantitative result of the same-level element relative to the previous-level element through pairwise comparison, constructing a judgment matrix, and finally comprehensively calculating and judging the weight values corresponding to the elements. The fuzzy comprehensive evaluation method is a method for comprehensively evaluating an object to be evaluated by using a fuzzy set theory.

The model is as follows: x = M E, X is a comprehensive evaluation vector, M is a weight vector, X is a fuzzy operator, and E is an evaluation matrix. In the process of model construction, the design of an evaluation index system and the acquisition of index weight vectors are key points.

10. Method of patent merit

The patent value degree method is used for comprehensively evaluating the patent value from three dimensions of law, technology and economy; the legal value degree comprises seven segment indexes of patented stability, evasiveness, dependence, patent infringement judgability, validity period, multi-country application and patent permission condition; the technical value degree comprises six subdivision indexes of advancement, industry development tendency, application range, matching technology dependence, replaceability and maturity; the economic value degree comprises five segmentation indexes of market application, market scale, market share, competitors and policy adaptability. The system still has some defects, which restrict further development and application.

11. Non-market benchmark method

The non-market-based method and the non-market-based patent value evaluation method are widely researched and applied in the west in recent decades by means of a metrological and economic model. The method mainly comprises the steps of collecting values of certain specific patent applications and implementation indexes (such as patent request numbers, patent family numbers, patent citation numbers and the like) in a public patent database, searching the relation between the indexes and the patent values by using an empirical research method, and further constructing a metrological economic model to evaluate the patent values. Representative of the comparison are the LanjOUW.Schankerman patent value assessment model (LS model) and Harhoff demonstration study.

12. European style expanding option method

The European expanding option method comprises the following steps:

1) binomial model (B.M) method and 2) black. Wherein 1) Binomial model (B.M) method: the return on a stock call option is equal to the return on a set of portfolios or "synthetic options" that include borrowing funds and buying stocks. The price evaluation method can construct an investment portfolio model containing borrows and stocks equal to the benefit of the option item through copying, but the model becomes very complicated due to a plurality of possibilities;

2) scholes (B-S) option price model: the values of Fisher Black and Myron Scholes hypothetical targeted assets taught by Chicago university in 1973 obey a logarithmic distribution, with changes in the targeted asset value values being described by geometric Brown's motion.

13. Four-factor patent value evaluation method

The patent value V = evaluation coefficient K multiplied by the patent basic value parameter P + the comprehensive control parameter value delta;

K∈(0,1)

the first step is as follows: and (4) calculating a patent basic value parameter P as a basic value of the patent value evaluation.

Patent basic value parameter P = (target market value Q) × (protection strength S) × (substitutability T) S ∈ (0,1), T ∈ (0,1)

The second step is that: accounting for patent technical quality Z

The patent technical quality Z is calculated from a patent technical quality index system and calculated in 10 cents.

The third step: calculating comprehensive evaluation coefficient K according to patent technology quality

Evaluation coefficient K oc of patent technology quality ZK e (0,1)

The fourth step: and adding a comprehensive control parameter value delta, wherein the delta value is formed by other factors and can be negative or positive.

14. Differential cutting method

The difference method is that the total amount estimated by the income present value method is subtracted by the amount of the tangible assets estimated by the reset cost method, namely the intangible asset value of the enterprise, and then the intangible assets except the patent right are further subtracted, so that the value of the enterprise patent right can be obtained.

Any one patent value evaluation model can be adopted in the embodiment of the invention, and a weighted average value can be obtained by mutually contrasting a plurality of patent value evaluation models.

And S104, acquiring information of one patent right in the node, calculating to obtain a corresponding single patent right market value through a preset value evaluation model according to the information, and obtaining a corresponding value contribution rate according to the ratio of the single patent right market value to the total market value.

Specifically, the corresponding model parameters are obtained from the information in the nodes according to a preset value evaluation model, so that the single patent right market value corresponding to the patent right is obtained.

Wherein the storing of information of all patent rights between each node based on the consensus mechanism specifically comprises: and when the information of each patent right changes, each node can acquire and record the change condition of the information according to the consensus mechanism.

Under the background that the technology of 'metas' is continuously evolved and advanced, the patent transaction platform can dynamically store various information related to patent rights, patentees, patent examination organizations and the like based on the block chain technology, and based on the division of various angles, patent packages formed by patent right sets can be randomly combined and transmitted in the technical mode of 'metas'; the implementation subject selects to implement the relevant patent packages according to the actual requirements, receives the 'permission or assignment' of the patent packages and pays in a package; the patent transaction platform needs to identify the value contribution degrees corresponding to the single patent rights of different sources, different fields and different time periods, and distributes profits to the patentees according to the value contribution degrees. In addition, in the context of patent infringement litigation, the solution of the patent technology may also be used to assist in calculating the amount of patent damage reimbursement.

The technical maturity is in different stages, a large amount of prior art exists, the market total value corresponding to the patent package reflects the market value of the patent technology to the industry or products, and further the current value contribution degree of the single patent right is obtained through the weight proportion relation of the market value of the single patent right and the market value of the single patent right based on the market total value, so that the objectivity and the operability are better.
