Description

Method of evaluating the value of technology for patent}

The present invention relates to a method for evaluating the value of a patent technology using a communication means such as a smart phone or a computer, more specifically, by applying a programmatic technology life and technology strength analysis techniques based on patent analysis techniques in real time In this regard, the present invention relates to a technology for more objectively calculating the valuation of patents.

Many patents (techniques) are created by companies, universities, and research institutes, including individuals, but the actual cases of commercialization by linking the patents (techniques) to products are reported to be insignificant compared to the number of applications.

It is understood that it is difficult to realize the commercialization because individuals and companies, which are the main players of the market launch, have big obstacles such as financing and technology from patent application to market launch.

This reality is similar to that of developed countries such as Japan and the United States as well as domestic countries.However, in developed countries, individuals or institutions who have the ability to patent patents having high potential value through technology trading and technology transfer are led by technology commercialization. Various institutions are in place to create value.

    Efforts have been made to promote technology transfer, technology transaction, and technology commercialization in Korea such as university TLO, but the biggest problem reported is the understanding of technology and technology value between technology suppliers and technology consumers. It can be said.

The technical value evaluation agencies that are considered to be reliable include domestic appearing institutions such as the Korea Technology Guarantee Fund, the Korea Institute of Science and Technology Information, and large patent corporations or accounting firms. It is reported to be more than 20 million won, and the cost of technology valuation is recognized as a considerable amount by individuals and business associates, and technology transactions through valuation are not properly performed.

Therefore, if the company provides a technology for evaluating the value and assessing the technical value through smartphone terminology applications or computer programs that can easily access patents owned by individual or business associates, the direction and plans for the commercialization of the technology will be provided to the technical client. It is expected that this will be a great help in establishing a business model, which will ultimately lead to the expansion of technology trading and technology transfer markets, thus forming a virtuous cycle of value chains.

    Table 1 shows the calculation basis for the technical value evaluation based on the cost approach. Cost approach most commonly used as a technology valuation technique In order to perform a technology valuation, at least nine inputs are required, including an industry-specific database.

However, there is a great gap for the general public who lacks accounting knowledge to approach this method of calculation, and it is recognized as a big obstacle in value estimation.

In addition, for accurate technology value evaluation, it is important to accurately analyze the contribution of technology according to the patented technology, but it is very important to calculate the right strength of the technology correctly for calculating the technology contribution, but most experts are unable to process this programmatically. It is difficult to produce an immediate evaluation result and causes an increase in the cost of evaluation.

The present invention is to solve this problem, it is easy to use by consumers (individual inventors, industry-university associations) who want to evaluate the technology, and a method for improving the reliability of the evaluation is required, and to preoccupy the market and create a new profit model IT It is intended to provide a patent technology app evaluation app with a smartphone application converged with.

In particular, the present invention is intended to be able to provide the evaluation results in real time while having high evaluation reliability by objectively calculating the lifespan or strength of technology by applying a patent analysis technique.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention. In the present embodiment, a method for valuation of a patented technology using an application for a smartphone will be exemplified, but the present invention is not limited thereto, and it is obvious that the present invention can be applied to a PC, a notebook, a communication terminal, etc., which can use the Internet or various communication networks.

1 is a block diagram of a patent technology valuation system according to the present invention.

As shown in FIG. 1, the patent technology valuation system according to the present invention includes a communication terminal 100 such as a smart phone, a patent information server 200, a valuation agency server 300, and a technology exchange server 400. It is configured to include.

The communication terminal 100 may be a smart phone, and in the case of a smart phone, an application (aka app) for evaluating the technical value is preferably installed.

The patent information server 200 provides a patent bibliography, a bulletin, a family information, a citation and citation of a patent, and the like, and includes a patent DB 210 stored in a processed form.

The valuation agency server 300 is a computer installed in an organization that performs technical valuation (Technology Guarantee Fund, etc.) and includes a valuation agency DB 310 in which standard discount rates and industrial technology element values for each technical classification are stored. Although the standard discount rate for each technology classification or the value of the industrial technology factor is determined by a separate formula, it is common to use the average value of the industry in a general valuation institution because the calculation is complicated, so accepting these conventions, the standard discount rate or industrial technology provided by the valuation agency The method was adopted to evaluate the technical value by applying element values.

The standard discount rate refers to the interest rate used to convert the value of a specific point in time into the value of the present (or base point), which is divided into seven sectors (construction, transportation, machinery, technical services, materials, chemicals, IT), and Forty-two standard discount rates are categorized into types and scales (KOSPI, KOSDAQ, Unlisted (large), Unlisted (medium), Unlisted (small), Unlisted (founding)).

Industrial technology factor refers to the maximum rate at which a technology asset can contribute to the potentially achievable commercial value in an industry, and is divided into seven industries (construction, transportation, machinery, technical services, materials, chemicals, IT). Descriptive elements can be defined in advance.

The technology exchange server 400 is provided with a corporate standard financial statement DB 410 for providing a standard financial statement for each industry for the technical value evaluation. Standard financial statements for each sector may be better broken down by the number of employees or sales size to increase the accuracy of the estimate.

Is a flowchart illustrating a process of calculating a value of a corresponding technology project according to the present invention, FIG. 6 is a flowchart illustrating a process of calculating individual technical strengths according to the present invention, and FIG. 7 is a value of technology according to the present invention. It is a flow chart showing the process. Each flow chart below reveals a process performed through an application for valuation of patent technology installed in the communication terminal 100.

As shown in Figure 2, the technology value evaluation process according to the present invention, first, after the user runs the application for valuation of patent technology installed in his communication terminal 100, the patent registration number of the technology to evaluate the value Enter (S10).

If the patent registration number is entered, the lifetime of the patent technology is calculated (S20). The technical life calculation process will be described in detail with reference to FIG. 3 as follows.

When the patent number is input (S100), the communication terminal 100 receives the patent document from the patent information server 200 (S110), and extracts bibliographic data and claims data from the received patent document (S120). Bibliographic data includes information such as international patent classification, owner, inventor, family information, and the number of claims.

The communication terminal 100 extracts the international patent classification included in the bibliographic data, and requests and receives citation patent life index information of the international patent classification from the patent information server 200 to calculate the technical life of the patent technology ( S130, S140). The cited patent life index measures the frequency of citations per year when the patents belonging to the IPC classification are cited by other patents, and exceeds the period such as the average citation frequency. As a technique of estimating the lifespan, a patent belonging to the international patent classification received from the patent information server 200 in the communication terminal 100 in addition to the method of providing the cited patent life index by the international patent classification in the patent information server 200. It is also possible to calculate the citation patent life index using the yearly citation data.

In addition to the method of using only the cited patent life index method in order to increase the accuracy of the technical life determination, for example, a method in which the technical life expectation of the patent holder is expected to be combined with the technical life calculated by the cited patent life index method may be calculated as follows.

Example: Technical life = (Technical life x 0.7) + (Expected technical life of patent holder x 0.3)

When the technical life is calculated, the free cash flow is calculated (S30). The process of calculating the free cash flow will be described in detail with reference to FIG. 4 as follows.

First, the technical classification corresponding to the international patent classification is determined (S200). Since the international patent classification and the technical classification used in the industry are different, it is necessary to prepare a table in advance between the international patent classification and the industrial technical classification.

When the technology classification is determined, the communication terminal 100 receives the average financial statement data of the technology classification from the technology exchange server 400 (S210), and estimates the sales amount according to the patent technology based on the received data (S210). S220), the accounting factors such as cost of sales, SG & A expenses, corporate tax, increase and decrease of working capital, etc. are calculated to calculate the free cash flow (S230).

In other words, it is difficult to accurately evaluate the cost of sales and sales according to the commercialization of the patented technology. Therefore, the cost of sales and sales are estimated using average financial data of the same industry. Here, it would be desirable to build a standard financial statement DB by size of the company to increase the accuracy of the estimation by applying the average value of companies corresponding to the type and size of the technology holding company.

When the free cash flow is calculated, the value of the technology business is calculated (S40). The process of calculating the value of the technology business will be described in detail with reference to FIG. 5 as follows.

When the communication terminal 100 receives the standard discount rate information corresponding to the technical classification from the valuation agency server 300 (S300), the present terminal calculates the present value of the technology by applying the received standard discount rate (S310), and the calculated technology The value of the technology business is calculated based on the present value of (S320).

The discount rate is calculated as the sum of the weighted average cost of capital (WACC) and the spread (risk premium), but as described above, in the present invention, a standard discount rate provided by a valuation agency is applied to simplify the calculation. It was.

The present value of a technology is calculated as the product of free cash flows and the discount rate of the technology category, and the value of the technology business is calculated as the sum of the technology values for the year over the life of the technology.

When the value of the technology project is calculated, the individual technical strength is calculated (S50). The process of calculating the individual technical strength is described in detail with reference to FIG. 6 as follows.

First, the patent right strength is calculated (S400). The right intensity of a patent can be calculated by calculating the index items, calculating the ratings for each item, and then summing the ratings for each item.

Here, the index item may include the number of family countries, the number of claims, the number of claims words, the number of essential components of the representative claim, the number of rights limitation elements, as shown in Table 2, The weight of each item is calculated by multiplying the weights.

For example, index items can be given as 1 point if there are no family countries, 2 points if 2 or less, 3 points for 5 or less, 4 points for 7 or less, 5 points for 8 or more.

The weight is used to distinguish between the items of high importance and the low importance in each index item. For example, it is possible to give a high weight to the number of family countries and the number of essential components.

Here, the number of essential components is the number of identifiers (; or: and, and,, etc.) indicating the end of one component, the number of special characters (%, weight ratio, parts by weight, etc.) indicating the ratio of components. It is preferable to calculate in consideration of any one or more of the number. As it is well known, the more the required components, the more room for avoidance design is generally. Therefore, the larger the number of the required components, the lower the rating.

In addition, the limitation scope of rights may include numerical limitations, preset sub-concept words (bolts, nuts, nails, springs, sponges, etc.), equations, preset material expression words, preset shapes or position-limiting words (metal materials, synthetic resins, etc.). The higher the number, the lower the rating.

When the patent right strength is calculated, commercial superiority information is input by the user (S410). In the case of commercial superiority, it is difficult to programmatically accurately calculate, so that the user directly inputs the commercial superiority of the patented technology.

Once patent rights strength and commercial superiority information are available, they are combined to calculate technical contributions.

When the individual technical strength is calculated, the individual technical strength is calculated (S50). The process of calculating the individual technical strength is described in detail with reference to FIG. 6 as follows.

First, an industrial technology element is calculated (S500). The industrial technology factor is calculated as the maximum real intangible asset value ratio by industry x average technology asset value ratio by industry.However, for the sake of simplicity, the industrial technology factors provided by the technology guarantee fund can be used as shown in Table 3.

When the industrial technology factor is calculated, the technical contribution is calculated by multiplying the individual technical strength value calculated in the step S50 by the industrial technology factor (S510).

When the technical contribution is calculated, the value of the technology is finally calculated by the following equation (S520).

The present invention has the following advantages over the technology valuation method using a conventional network.

1. Minimization of User Input Items: Only the patent holder's evaluation score for patent registration number and commercial superiority is required.

2. Improvement of evaluation accuracy through option of item change: It is also possible to improve evaluation accuracy by allowing users to directly input values for factors such as increase in technical lifespan sales in addition to basic input items.

3. Automated technical life calculation and accuracy improvement: It is possible to estimate the technical life expectancy from the patent point of view using the citation patent life index method, and can additionally improve the accuracy by combining the expected technical life of the user.

4. Automatic determination of technology classification: Extract information from patent data and automatically determine technology classification of the technology from it.

5. Improve the accuracy of free cash calculation: add standard number of employees or sales scale to build standard financial statements, and apply the standard standard financial statement data of companies corresponding to the type and size of technology holding company Improving

In the present embodiment, the case where the necessary information is received from the patent information server, the valuation agency server, the technology exchange server, etc. is illustrated. Of course, it is also possible to be provided in the communication terminal 100.
