  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram of the information processing apparatus according to the present embodiment. The information processing apparatus 100 includes a company patent database (hereinafter referred to as DB) 101, a patent rating unit 103, a company financial / market price information DB 104, a company patent power index DB 105, a patent asset value calculator 106, and a model parameter calculator 107. A model parameter DB 108, an evaluation target patent DB 111, a patent value calculation unit 113, and an output unit 114.

  This information processing apparatus 100 uses the information on a plurality of patent rights held by each of a plurality of companies and the information such as the financial and stock market capitalization of each of the plurality of companies to obtain the economic value (patent value) of the patent right. The parameter of the model for calculating is calculated, and the patent value of the patent right to be evaluated is calculated using the calculated parameter. Hereinafter, the information processing apparatus 100 will be described in detail.

  The company patent DB 101 stores information on a plurality of patent rights (individual patent information) held by each company. The individual patent information includes bibliographic items (patent numbers, application numbers, applicants, names of inventions, etc.) of patent rights, history information relating to the patent rights, technical classification of the invention related to the patent rights, and the like. The history information specifically includes the number of histories of various patent histories generated in the application or patent right from the application to the patent regarding the patent right and after the patent.

  FIG. 2 shows an example of the data structure of the company-specific patent DB 101. The company-specific patent DB 101 has columns of bibliographic items such as company names, patent numbers, history information (history 1 times to history N times), and technology classification. Actually, a value is set in each column, but the description of the value is omitted here except for the company name.

  The company name is the name of the company that holds the patent right. The patent number is a patent number of a patent right granted by an organization such as the Patent Office. The patent may be a patent right granted by the Japan Patent Office or a patent right granted by an organization such as a foreign patent office. Here, it covers Japanese patent rights. The company may be a Japanese company or a foreign company. In addition to the company name and the company patent right, an individual name and an individual patent right may be registered.

  The number of times of history 1 to history N is the number of times history 1 to history N occurred. Examples of the histories 1 to N include the following. For example, the number of citations cited in the notice of reasons for refusal before patenting (may be counted separately for references relating to in-house applications and references relating to other companies' applications) Number of times of browsing (viewing) after or both, number of requests for invalidation trial, number of issuance of notice of reasons for refusal, number of countries applying for foreign applications based on the patent application, number of times information was provided or information For example, the total number of documents submitted for provision. These are only examples, and histories other than those listed here may be used. Such a history is considered useful for assessing the importance of patent rights.

  Information on the number of histories may be obtained from a public or private institution or company if such information is provided by the institution or company, or information published by the Patent Office etc. regarding patent rights. You may calculate by analyzing and analyzing. The method of acquiring the history count information is not limited to a specific method.

  The technical classification represents a technical field to which the invention pertaining to the patent right belongs. As an example of the technical classification, an IPC (International Patent Classification), FI (File Index), or a theme code assigned by the Patent Office may be used, or the user may define it based on an original standard. When a theme code is used, the number of patent rights varies greatly depending on the theme code. Therefore, a plurality of theme codes may be integrated into one, or a single theme code may be subdivided into a plurality. One of a plurality of IPCs assigned to a patent right (for example, the first IPC described at the top of the IPC entry column of the patent gazette) may be used as the technical classification, and the set of IPCs may be used as the technical classification. May be adopted. Moreover, you may select one of several theme codes provided with respect to the patent right as a technical classification, referring also to the first IPC.

  The patent rating unit 103 ranks each patent right held by each company based on the company-specific patent DB 101. More specifically, the patent rating unit 103 ranks patent rights among patent rights belonging to the same technical classification for all companies, and sets a rating value for the patent right. In order to properly evaluate the importance of a patent right, it is desirable to perform comparative evaluation (rating) between patent rights belonging to the same technical field, not different technical fields (for example, pharmaceuticals and optics).

  In general, it has been demonstrated that the importance of patent rights has a positive correlation with the number of histories described above. Using this property, the patent rights are rated using the number of times of each history 1 to N.

  First, for a patent right, a raw score is obtained by adding a preset weight to the number of times of each history. An example of an equation for obtaining a raw point is shown below as Equation (1). In order to relieve the distortion of the distribution of the raw points, a process such as logarithmization may be performed on the obtained raw points. The calculation formula for the raw points is common to all technical classifications. Note that there is at least one type of history to be used, and it is assumed here that a plurality of histories are used.

Element of each patent right = Σ [weight _s ] * [number of history _s ] (s represents the type of history) Formula (1)

  The number of histories may be appropriately standardized according to the age of the patent right. This is to avoid biasing a patent right whose filing date or registration date is old because the number of histories generally increases with time.

  The weight of each history is preferably determined based on the degree of influence each history has on the economic value of the patent right. For example, the strength of the correlation between the number of each history of patent rights held by a company and the company value or stock return (stock price, etc.) is determined for each company, and the weight for each history is determined according to the strength of the correlation. Can also be determined. At this time, the number of times of each history for each company may be standardized based on the company size or the like (number of employees, market capitalization, etc.).

  The patent rating unit 103 obtains the average value and standard deviation of the raw points of the patent right for each technical classification, and obtains a normal distribution of the average value and standard deviation. Then, the normal distribution is converted into a standard normal distribution. The raw points of each patent right are converted from the points in the normal distribution to the points in the standard normal distribution. The converted point value is used as the rating value of the patent right. This is done for each technical classification. As a result, patent rights are rated (relative comparison) in units of technical classification. The standard normal distribution is a normal distribution having an average of 0 and a standard deviation of 1.

  The patent rating unit 103 stores the rating value of each patent right in a storage device accessible from the model parameter calculation unit 107. A rating value column may be provided in the company patent DB 101, and the rating value may be stored in the column.

  The company-specific financial / market price information DB 104 stores information on balance sheets (balance sheets) of a plurality of companies. For example, values of predetermined items such as assets, liabilities, and net assets in the balance sheet are stored. The balance sheet of each company may be the one included in the securities report of each company. Further, the company-specific financial / market price information DB 104 stores the stock market value of each of a plurality of companies. The market capitalization value may be distributed by public or private institutions or companies. Since the stock market capitalization fluctuates from day to day, it is also possible to use statistical values such as an arbitrarily selected date or a specific date, or an average value, maximum value, minimum value, etc., for a specific period. An example of the data structure of the company-specific financial / market price information DB 104 is shown in FIG. Note that all the columns shown in FIG. 3 are not essential, and for example, the net asset column may not exist.

  The patent power index DB 105 by company stores the patent power index 1 to the patent power index M for each of a plurality of companies. The patentability index represents a company's willingness to acquire a patent, the degree of attention of a third party to the company's patent right or application, the degree of influence of the company's patent right or application on the acquisition of patent rights of other companies, and the like. An example of the data structure of the company-specific patent power index DB 105 is shown in FIG.

  Examples of information used as a component for calculating a patent power index include the number of applications filed by a company within a predetermined period and the number of patent rights held by the company. In addition, there is the number of citations, which is the number of times a patent based on a company or a gazette based on an application has been cited in the rights-making process (examination process, trial process, etc.) of another company. In addition, there is the number of patent applications for which information is provided (number of information provisions) among patent applications filed within a predetermined period by the company. In addition, there is a ratio (priority claim ratio) of patent applications in which priority claims are made based on the Paris Convention among patent applications filed by companies within a predetermined period. The percentage of patent applications for which a company received a decision of rejection within a specified period or a patent application filed within a specified period of which was rejected (the ratio of appeals against decision of rejection) ) The information as an example here may be used to calculate the patentability index by standardizing the company scale or the number of patent rights, etc., or a relational expression between a plurality of variables representing the reference information (for example, The patentability index may be calculated by weighted sum). The company-specific patent power index DB 105 stores a plurality of patent power indices calculated in this manner.

  The patent asset value calculation unit 106 calculates a company value (book value) and a company value (market price) for each of a plurality of companies based on the company-specific financial / market price information DB 104. As the corporate value (book value), the value of the asset stored in the corporate financial / market price information DB 104, that is, the value of the balance sheet asset (A) may be used. Alternatively, the corporate value (book value) may be calculated from the sum of the balance sheet debt and net assets. If the asset is A, the liability is L, and the net asset is E, then A = L + E.

  The corporate value (market price) is calculated by the sum of the value of the liability stored in the corporate financial / market price information DB 104 and the value of the stock market capitalization. That is, it is calculated by the sum of the balance sheet debt and the market capitalization. When corporate value (market price) is V, debt is L, and stock market capitalization is E ′, V = L + E ′. The market capitalization (E ') may be smaller than the net asset (E) of the balance sheet.

  Here, it is assumed that the corporate value (market price) V is composed of a tangible asset and an intangible asset of the enterprise, and an asset of a patent right (patent asset) in the intangible asset is calculated. The details will be described below.

If the tangible asset of a company is expressed as e ^c A and the intangible asset is expressed as e ^c γK, the enterprise value (market price) V can be modeled by the following equation (2). This formula is one of the models widely used in the study of intangible assets. e is an exponential (= 2.71828...). c and γ are parameters relating to intangible assets.

  If i is a variable that represents a company and a model is written for each company, it is as follows.

Intangible assets (e ^c γK) include assets related to patent rights (patent assets) and assets related to things other than patent rights (trademarks, brands, etc.) (non-patent assets). Assuming that a part of the intangible asset e ^c γK is a patent asset, the parameters c and γ are determined using the surrogate variables using the above-described patent power index.

  First, when the equation (3) is logarithmized, the following equation is obtained.

“Ki / Ai” in Expression (4) is divided into a part W _i relating to patent assets and the other part W ′ _i as follows.

The proxy variable of the part W _i relating to the patent asset is represented as w _i . The proxy variable w _i is an explanatory variable, the objective variable is log (Vi / Ai), and an expression (6) representing these relationships is created as follows. u _i is an error term. The portion W ′ _i other than the patent asset is reflected in the error term u _i . With Vi / Ai and proxy w _i of a plurality of companies, by performing a regression analysis, to estimate the parameters c, gamma. As an estimation method, a least square method can be used as an example, but is not limited thereto.

The proxy variable w _i is calculated for each company i based on the above-described patent power index 1 to patent power index M and based on a predetermined calculation formula (proxy variable calculation formula). The proxy variable calculation formula is common to all companies. The proxy variable calculation formula is not limited to a specific form, but as an example, one value of the patentability indexes 1 to M may be used as it is. Some sums or weighted sums of the patent power indexes 1 to M may be used. Other methods than those described here may be used. For example, a common factor extracted by factor analysis from a plurality of patent power indexes may be used.

The patent asset value calculation unit 106 uses the estimated parameters c and γ to calculate the patent asset value for each company based on the asset A _i and the proxy variable w _i .
Specifically e ^c γA _i w _i
To calculate the patent asset value of the company (calculated from the company assets).

  The patent asset value of a company is the economic value of a patent asset in the value of a company asset evaluated at market value. Most patent assets of companies are off-balance, and in order to recognize their value, it is necessary to estimate the value of patent assets from the known company value (book value). Therefore, in this embodiment, under the assumption that the patent value as an intangible asset is reflected in the market value evaluation of the corporate value through the stock market etc., Tobin's q (= V / A) is based on the patent strength index. Regression analysis is performed using a model related by proxy variables. In this way, patent assets are evaluated. The Tobin's q equation used here is based on a simple method, and a more formal calculation method may be used.

The patent asset value e ^c γA _i w _{i for} each company i calculated by the patent asset value calculation unit 106 is stored in a storage device accessible from the model parameter calculation unit 107. Note that a company patent asset value column may be provided in the company patent power index DB 105 or the company financial / market price information DB 104, and the company patent asset value may be stored in the column.

  The model parameter calculation unit 107 calculates the parameters of the patent evaluation model for each technical classification. The patent evaluation model is a model that associates the rating value of a patent right, a parameter, and the economic value (patent value) of the patent right, uses the rating value of the patent right as an input variable, and uses the patent value as an output variable. As an example, the patent value represents the total present discount value of the portion that contributes to the patent right in the cash flow obtained by using the patent right.

  In each company, it is assumed that the patent asset value of the entire company and the sum of the patent values of the individual patent rights held by the company match. This relationship is expressed by the following formula. j is a variable representing each patent right held by the company. If the number of patent rights held by the company is g, j takes a value of 1 to g.

  Patent asset value of the whole company = patent value of Σ [individual patent right j]

The patent evaluation model can be generally expressed by a function f (x, a _k , b _k ). If the number of technical classifications is z, k takes a value of 1 to z. x is a rating value. As described above, x is normalized so as to have a normal distribution. a _k and b _k are unknown parameters. There are as many patent evaluation models as there are technical classifications. The form of f (x, a _k , b _k ) is not limited to a specific one, but the following formula can be used as an example.

a _k represents the technical classification of how much the patent value increases when the rating value increases by one unit, and b _k represents the average patent value of the technical classification.

  The form of the function f depends on the shape of the distribution of rating values, but generally, the higher the rating, the higher the economic value of the patent right. Also, in the distribution of the economic value of patent rights, it is assumed that some patent rights have very high economic value, but the economic value of most patent rights is not high. It is desirable for the function to rise steeply rather than a function that increases linearly. The above equation (7) is one of the functions that satisfy these conditions, but it does not prevent other functions from being used.

  Considering the age of the patent right, the patent evaluation model may be expressed by the following formula. d is the patent obsolescence rate and is a known number. It takes into account that the longer the age of a patent right, the lower the value of the patent. d may be a value common to the patent evaluation models of all the technical classifications, or may be a different value for each technical classification. In the following description, Expression (7) is used, but Expression (8) may be used.

The model parameter calculation unit 107 uses a patent evaluation model for each technical classification (parameters a and b are unknown at this time), and for each company, an equation y _i that integrates the patent value of each patent right held by the company. Create i is a variable representing a company.

An example of the integration formula to be created is shown below. Number of companies is a 600 (i = _1~600), has created a 600 equations y _{1 ~y 600.}

Each term on the right side of each formula corresponds to the economic value of each patent right held by the company. Therefore, the number of terms on the right side matches the number of patent rights. For example, when a company with i = 1 has 3000 patents, the number of terms on the right side of y ₁ is 3000. The subscripts “a” and “b” are variables representing the technical classification, and take values of 1 to z (z is the number of technical classifications). x is a rating value of the corresponding patent right (calculated by the patent rating unit 103).

The model parameter calculation unit 107 creates a formula representing the difference ε _i between the integration formula y _i for each company and the patent asset value e ^c γA _i w _{i for} each company calculated by the patent asset value calculation unit 106. This equation can generally be expressed as:

When the number of companies is 600, 600 formulas can be created as follows.

The model parameter calculation unit 107 reduces the difference ε _i between these companies, more specifically, the parameter a (a _{1 to} az) and the parameter b (to reduce the difference ε _i between these companies at the same time. b ₁ ~b _z) is calculated. As a method for calculating these parameters, for example, a least square method can be used. In this case, for example, the parameters a _{1 to} a _z and the parameters b _{1 to} b _z may be determined so as to minimize the following expression L. In this example, the number of companies is 600.

In addition to the least square method, a non-linear least square method or a method of minimizing an absolute value sum (Σ | ε _i |) may be used. Further, non-parametric methods (neural networks, genetic algorithms, etc.) may be used.

The model parameter calculation unit 107 stores the parameter a _{k (k = 1 to z)} and the parameter b _{k (k = 1 to z)} of the patent evaluation model calculated for each technical classification in the model parameter DB 108. An example of the data structure of the model parameter DB 108 is shown in FIG.

  The evaluation object patent DB 111 stores individual patent information of a patent right (evaluation object patent right) to be evaluated. More specifically, the evaluation target patent DB 111 stores bibliographic items such as patent numbers, history 1 times to history N times, technical classification, etc., for patent rights whose economic value is to be evaluated. An example of the data structure of the evaluation target patent DB 111 is shown in FIG. The history 1 times to the history N times and the meaning of the technology classification are the same as those of the company-specific patent DB 101. The patent right to be evaluated need not be the same as the patent right registered in the company-specific patent DB 101. For example, a patent right issued after calculation of the model parameter may be used, or a patent right of a company other than the company registered in the company-specific patent DB 101 may be used. In addition to corporate patent rights, individual patent rights may also be used. Although the present embodiment has been described with respect to Japanese patent rights, the present invention can be similarly implemented with respect to patent rights in other countries such as US patent rights.

  The patent value calculation unit 113 reads the individual patent information of the evaluation target patent right from the evaluation target patent DB 111. The individual patent information of the patent right designated by the user among the evaluation subject patent rights registered in the evaluation subject patent DB 111 may be read out in order from the first column. Alternatively, the patent value calculation unit 113 may receive input of a patent number, history number 1 to history number N, and technical classification from the user via the input interface from the application screen.

The patent value calculation unit 113 obtains a raw point of the patent right to be evaluated according to the formula (1) based on the number of history of the patent right to be evaluated to the number of times N, and uses the standard normal distribution of the corresponding technical classification. The rating value x is calculated from the raw points. Further, the patent value calculation unit 113 reads the parameter a _k and the parameter b _k corresponding to the technical classification from the technical classification of the evaluation target patent right from the model parameter DB 108. For example, in the case of the technical classification 7, the parameter a ₇ and the parameter b ₇ are read out. The economic value (patent value) of the patent right to be evaluated is calculated by calculating Expression (7) based on the read parameter a _k and parameter b _k and the calculated rating value.

  The output unit 114 outputs data including the patent value calculated by the patent value calculation unit 113. For example, the patent value may be written in a predetermined file together with the patent number, or may be output on the screen of the display device. Further, the data including the patent value may be transmitted wirelessly or by wire to an external device via the communication interface. Further, a patent value column may be provided in the evaluation target patent DB 111, and the calculated patent value may be written in the column.

  FIG. 7 shows a hardware configuration example of the information processing apparatus 100. The information processing apparatus 100 includes a CPU 201, an input interface 202, a display unit 203, a communication interface 204, a main storage unit 205, and an external storage unit 206, which are connected to each other via a bus 207 so as to communicate with each other.

  The input interface 202 includes input devices such as a keyboard, a mouse, and a touch panel. The display unit 203 includes a display such as an LCD (Liquid Crystal Display) and a CRT (Cathode Ray Tube). The communication interface 204 includes a wireless or wired communication circuit, and communicates with an external device using a predetermined communication method.

  The external storage unit 206 includes, for example, an HDD, an SSD, a memory device, a storage medium such as a CD-R, a CD-RW, a DVD-RAM, and a DVD-R. The external storage unit 206 stores a program for causing the CPU 201 to execute the functions of the patent rating unit 103, the patent asset value calculation unit 106, the model parameter calculation unit 107, the patent value calculation unit 113, and the output unit 114. The external storage unit 206 includes a company-specific patent DB 101, a company-specific financial / market price information DB 104, a company-specific patent power index DB 105, and an evaluation target patent DB 111.

  The main storage unit 205 expands the control program stored in the external storage unit 206 under the control of the CPU 201, and stores data necessary for executing the program, data generated by the execution of the program, and the like. The main storage unit 205 includes an arbitrary memory such as a nonvolatile memory or a volatile memory. The CPU 201 reads out the program from the main storage unit 205 and executes it, whereby the functions of the patent rating unit 103, the patent asset value calculation unit 106, the model parameter calculation unit 107, the patent value calculation unit 113, and the output unit 114 in FIG. Is realized. The data of at least one of the company-specific patent DB 101, the company-specific financial / market price information DB 104, the company-specific patent power index DB 105, and the evaluation-target patent DB 111 is received from the outside via the communication interface 204, and the external storage device 206 may be stored.

  The information processing apparatus 100 may be incorporated in a personal computer, a notebook personal computer, or the like, or may be arranged as a server apparatus on a communication network such as the Internet. Further, the functions of the information processing apparatus 100 may be realized by distributing the functions of the information processing apparatus 100 to a plurality of apparatuses and operating the plurality of apparatuses in cooperation via a communication network.

  The operation of the information processing apparatus 100 according to the present embodiment mainly includes a model parameter calculation phase and a patent value calculation phase. These phases can be executed at independent timings, but can also be executed continuously.

  FIG. 8A is a flowchart of the model parameter calculation phase according to the present embodiment.

(Step 301) For each patent right registered for each company registered in the company-specific patent DB 101, the patent rating unit 103 uses the history 1 times to the history N times to determine the rating value of the patent right in units of technical classification. calculate.

(Step 302) The patent asset value calculation unit 106 calculates the patent asset value for each company based on the company-specific financial / market price information DB 104 and the company-specific patent power index DB 105. Specifically, the corporate value (market price: V) is calculated by adding the corporate debt (L) and the market capitalization (E ′). A model (see equation (6)) that expresses the relationship between Tobin's Q (= V _i / A _i ) based on corporate value (book value: A) and corporate value (market value: V) and proxy variable w _i By performing regression analysis, the parameters (γ, c described above) of the model are calculated. Surrogates w _i is calculated using at least one of patent power indicator 1~M registered enterprise by patent power index DB 105. The patent asset value e ^c γA _i w _i of the company is calculated from the calculated parameters (γ, c), the proxy variable w _i, and the company value (A _i ).

(Step 303) The model parameter calculation unit 107 sets a patent evaluation model (formula (7) or formula (8) or the like) including unknown parameters (the parameter a and the parameter b described above) for each technical classification. The patent evaluation model calculates a patent evaluation value from a rating value (input variable) of a patent right.

  The model parameter calculation unit 107 generates a term representing the patent value of each patent right from the rating value of each patent right and the patent evaluation model corresponding to the technical classification to which the invention pertaining to each patent right belongs. Generate an expression that represents the sum. And the formula (difference formula) showing the difference of the total value which the said formula expresses, and patent asset value is generated. This difference formula is generated for each company. The parameters are optimized so as to minimize the sum of the difference formulas for each company. Thereby, the parameters of the patent evaluation model are calculated for each technical classification. The calculated parameter data is stored in the storage device.

(Step 311) FIG. 8B is a flowchart of the patent value calculation phase according to this embodiment. The patent value calculation unit 113 reads the individual patent information (history 1 times to history N times, technical classification, etc.) of the patent right to be evaluated from the evaluation target patent DB 111. The patent value calculation unit 113 calculates the rating value of the patent right in the technical classification using the history 1 times to the history N times.

(Step 312) The patent value calculation unit 113 reads a parameter corresponding to the technical classification from the model parameter DB 108 based on the technical classification included in the individual patent information. Based on the read parameter and the calculated rating value, the patent value (economic value) of the patent right is calculated based on the patent evaluation model.

(Step 313) The output unit 114 outputs data including the patent value calculated by the patent value calculation unit 113.

  As described above, according to the embodiment of the present invention, based on the assumption that the patent asset value in the asset value of the company is equal to the total economic value of the individual patent rights held by the company, the patent right for each technical classification. A model for calculating economic value is calculated. By using this model, it is possible to appropriately calculate the economic value of the patent right to be evaluated.
