Figure 1 is a flowchart of a method for evaluating the market value of a core patent according to one embodiment of the disclosed technology. Referring to FIG. 1, a method for evaluating a market value of a core patent includes a step 110 of searching for a core patent for market value evaluation by the technology valuation system, A step 120 of searching a solution of the core patent, a step 130 of extracting technical characteristics of the core patent using a machine learning technique, searching for a target product to which the technology of the core patent is applied, (140) a step 140 of applying a weight if the utilization range of the target product corresponds to a field where a merger or acquisition of a large company occurs, a solution of the invention of the core patent, a technical characteristic, an application range of a target product, and a KPI (150) of calculating the market value based on the market value of the technical value system A step 160 that force.

In step 110, the technology valuation system searches for core patents that are to be evaluated for market value. In step 110, the technology valuation system searches the data of the database in advance to find the core patent.

Here, the core patents refer to registered patents that have a history of being acquired in the enterprise or used in litigation. That is, the core patent is a patent that has proven its worth from experts and has some objective value.

The technical valuation system receives predetermined information for searching for the core patent from a user, searches the own database pool, and finds the core patent.

In step 120, the technology valuation system searches for a solution of an invention for a pre-registered core patent. The solution of the above invention means a solution to the problem of the core patent. In one embodiment, the contents of the inventive task solution may be extracted from the searched core patent specification to define the solution of the invention of the core patent.

Meanwhile, the technology evaluation system is a system in which a technology evaluator or a patent expert calculates a technical or monetary value of a patent through a system. The technology evaluation system receives and receives specific information using a technology such as a semantic web or an ontology , It is possible to use it later to search the database or extract other information based on the above information.

In step 130, the technical valuation system extracts the technical characteristics of the core patent using a machine learning technique. See Figure 5 for a detailed description of the machine learning.

5 is a diagram illustrating a machine learning technique utilized in an embodiment of the disclosed technique. Referring to FIG. 5, the technology valuation system selects learning data, inputs selected learning data, learns the selected learning data, and searches for a core patent similar in solution to the evaluation target patent and the invention based on the learned data.

The machine learning technique belongs to a field of artificial intelligence, and is a basis on which a computer can learn information like a person and can perform specific processes such as search, analysis, comparison and judgment based on the information.

Most commonly, it recognizes characters in a specific document, learns what the characters have in each case, and learns about other characters with similar or similar meanings. Based on the learned information, it is possible to determine what contents are written in the document.

Since the machine learning technique is already well known in the art and is being continuously researched and developed, it can be applied to the technical valuation system to sufficiently utilize it to evaluate the market value of the core patent.

In operation 130, the technical value evaluation system extracts the technical characteristics of the core patent using the machine learning technique. Here, the technical features of the core patents refer to the concrete or detailed technical components or devices for implementing the inventive solution. For example, if the solution of the invention is voice recognition, the technical feature may be a terminal or device or a specific process or method used to perform the speech recognition.

In step 140, the technology valuation system searches for a target product to which the technology of the core patent is applied. Then, the utilization range of the target product is calculated.

Here, the target product refers to a product that is completed or sold on the market to reflect a specific technology. The core patents used for comparison in the disclosed technology include those purchased by the enterprise.

In general, the purchase of a patent by a company is a reason for producing a monetary profit based on the technical features included in the patent, or a reason for producing the product by utilizing the purchased patent later.

Therefore, it is determined in step 140 whether there are any target products to which the evaluation target technology is applied, the market to which the products are related, and the degree of position in the market.

On the other hand, the technology value evaluation system can provide a database for the target product in advance. For example, the technology valuation system includes a target product database, and what kind of target products are in the database and how much the range of the products are.

On the other hand, it is possible to form and manage a plurality of databases together with a database used for searching core patents or calculating similarities between the core patents and evaluation target patents. The databases will be described with reference to FIGS. 3 and 4 below.

FIG. 3 is a drawing of attribute databases according to an embodiment of the disclosed technique. And FIG. 4 is a diagram illustrating a database generated based on a core patent according to an embodiment of the disclosed technology. 3 and 4, the technical valuation system includes an invention solution database, an extended invention solution database, a technology feature database, a target product database, and a UI / UX database.

The invention solution database stores information about the invention of the invention of the core patent. The extended invention solution database stores information on other core patents having technical features extended from the core patents.

In order to derive the extended invention solution, it is extended to a sequential method of deriving a problem that can be caused by the first extended solution and adding a solution to solve the above problem. When some cases are constructed, It is possible to do. At this time, weighting can be given by using the machine learning technique for each of the expanded invention solutions, and the weighting value can also be utilized at the time of searching the evaluation target technology.

Technical Features The database stores information on the technical characteristics of the core patents. The target product database is a database that stores information about the target products based on the technical contents of the core patents.

The databases can receive the information of the core patents corresponding to each attribute through the manager of the technical value evaluation system. The UI / UX database is used to extract the information stored in the databases and provide a new interface for evaluating the technology of the patent to be evaluated, which is inputted into the technical value evaluation system.

Meanwhile, as shown in FIG. 4, the databases analyze key patents input to the system through a manager through a machine learning technique, and classify and store the core patents according to attributes of each database. Here, the technology valuation system can further extract the expanded invention solution based on the invention solution of the core patent extracted through the machine learning technique.

For example, if the input core patent has an inventive solution for voice recognition, the technology valuation system can extract an inventive solution such as extended voice control or remote voice control in speech recognition as an extended invention solution.

In addition, a technical development matrix according to the input core patents can be formed separately. For example, it is possible to provide additional charts or charts indicating the technological development flow for a core patent in the form of family information according to a patent which the same inventor proceeds through a series of studies through a single category.

In addition, information on visual routine models and product use models can be provided. The visual routine model and product use model will be described later.

In step 150, the technology valuation system calculates a market value based on solutions, technical characteristics, and application range of the subject product of the core patent extracted in steps 110 to 140 previously. In order to calculate the market value of the core patent, the step 150 includes searching for a product reflected in the KPI (Key Performance Index) of the core patent 150a and matching the market data according to the product reflected in the KPI 150b. .

In step 150a, the technology valuation system can set key performance indicators of the core patents in advance, and search for products meeting the index. In one embodiment, there may be a product with a high degree of relevance and a product with a low degree of relevance in the target product for the core patent. Therefore, in the disclosed technology, it is possible to calculate the KPI for the purpose of performing a predetermined filtering or mining, and further search for a product matched thereto.

Naturally, the products reflected in the key performance indicators largely reflect the technical characteristics of the core patents, and it is possible to gauge the market value of the core patents in consideration of the marketability and the value of the monetary use of the products.

Also, in step 150b, the technology valuation system can match the market data according to the product reflected in the KPI, thereby providing a higher correlation to the user. In other words, it is possible to obtain a comparatively detailed view of the value of the core patent in the market by attaching objectively proven facts or results, and at the same time, how much value it has in the monetary aspect can be inverted.

Meanwhile, in step 150, the technology valuation system uses a composite index including technical maturity and expandability in order to evaluate the market value of the core patent.

The maturity of the technology is considered to be low in the maturity of the concrete embodiment or the concept of the concept in which the implementation method is not defined. On the other hand, the technology having a certain concrete form through a specific implementation method or example is highly mature Can be judged. In addition, it can be judged that the maturity of the technology is high even if the product has already been commercialized by applying the technology.

On the other hand, in the case of the conceptual technology, contrary to the maturity of the above-mentioned technology, the expandability is likely to expand because it can be expanded without limitation in various fields. However, It can be judged that the possibility of expansion is low.

The technology valuation system can measure the maturity and expandability of the technology as quantified values and store it in a database. And, the information can be indexed to evaluate the value of the technology relatively.

Meanwhile, as described above, the maturity and expandability of the technology may be used to evaluate the technology value, respectively, but it is possible to correct the accuracy according to the technology evaluation by adding the two pieces of indexed information through the following equation.

(Wherein,

Is a composite index,

Is the technology maturity index,

Is scalability,

And

Is a weight,

Is a value obtained by dividing the average of the technology maturity of the entire core patents by the maturity of the technology of the core patents searched,

Is the average of the expandability of the entire core patent divided by the average of the expandability of the key patents retrieved.)

In one embodiment, if the maturity index of the technology is high, while there is a technology that is relatively insufficiently expandable, it is highly likely that the technology is already being provided as a specific type of product or service in a market corresponding to the related field, The core patent including the above technology can be judged to have a high market value.

In addition, rather than simply judging the market value of the core patents from the contents of the surface, it is possible to set the weight of the mathematical expression in consideration of the possibility of the hidden technology such as know-how or trade secret, The technology evaluation can be performed.

In the case of products or industries in which mergers and acquisitions are taking place in the products or industries to which the technology to be evaluated is applied, if the weights are different in the market value evaluation, the reliability of the evaluation can be increased. For example, in a field where mergers and acquisitions of large corporations have occurred, if the target of merger and acquisition is a technology-based small company, the patent may be unofficial. Therefore, it is possible to increase the reliability of evaluation in fields where only core patents can not be evaluated.

In step 160, the technical value evaluation system outputs the market value of the core patent calculated in step 150 through a user interface. The technology valuation system used in the disclosed technology has a kind of database pool by classifying various information about the core patents and storing them in different databases.

Therefore, it is possible to provide the user with visual modeling so that the user can easily understand the information that can be extracted from the database pool.

6 to 8, a description will be given of a template for providing a user with a more easily understood result of the market value evaluation of the core patent.

6 is a diagram illustrating a visual routine model provided to a user in accordance with one embodiment of the disclosed technique. Referring to FIG. 6, the visual routine model is defined as providing a predetermined model in the technology valuation system so that the technical characteristics of the core patent can be more easily understood.

The visual routine model explains the characteristics of the technique to the user by using a commonly used expression, that is, a picture, a formula, a symbol, and an icon. As shown in FIG. 6, if a technical characteristic of a patent to be evaluated relates to a reversible voice control, the user can visually model that the TV, the camera, or the smart phone can be controlled by recognizing the voice of the user and provide the model to the user . Therefore, even those who have no expertise in the relevant field can easily understand what the technical characteristics of the technology to be evaluated are.

7 is a diagram illustrating a product use model provided to a user according to an embodiment of the disclosed technology. In conjunction with FIG. 6 above, the technology valuation system can provide a product use model for reversible speech control.

In one embodiment, assuming that the user controls device A by voice, the user is able to identify the voice command that is used to control A through the lexical dictionary for device A. In addition, you can visually check which devices are controlled by using some voice commands.

8 is a diagram of a technology evolution matrix provided to a user in accordance with one embodiment of the disclosed technique. Referring to FIG. 8, the technical valuation system can provide a technology development matrix for a patent to be evaluated, which is a technical feature of the reversible speech control, like the model provided in FIGS. 6 and 7 above.

In one embodiment, in the past, voice control was possible for only one specific device in voice control. However, at present, it is possible to control a plurality of devices using a plurality of voice control commands.

On the other hand, the past and present voice control techniques include certain problems as shown in the drawings. In the disclosed technology, it is possible to grasp the flow of the technology development and the problems that are generated in each step, It is predicted that a technology capable of reversibly controlling the voice of a plurality of devices will emerge.

Meanwhile, the models described with reference to FIGS. 6 to 8 can be expressed using a predetermined image, a symbol, a graphic form, and an icon stored in the UI / UX database of the technology value evaluation system. Alternatively, predetermined modeling information may be input in advance from the manager and various models may be provided.

9 is a diagram showing the results of the technology valuation in the disclosed technology. Referring to FIG. 9, it can be confirmed through the technology valuation system that the evaluation target technology has a relatively high value through comparison with the core patent, which is a technology evaluation criterion of the target patent.

In one embodiment, the first key patent is a technical feature that provides an integrated vocabulary dictionary for a target device such as a smart phone, and controls the target device using voice. In addition, And the second key patent is to provide a distributed lexical dictionary to remotely control a plurality of devices and extend them to perform reversible voice control, Since the evaluation target technology to be compared may be extended to an adaptive voice control technology capable of reversible voice control and transmitting voice to one of the devices and controlling the other devices using the voice, Is compared with the above-mentioned core patents, and it is determined whether there is a relatively technical value in the system It is possible to evaluate.

Meanwhile, the technical valuation system used in the disclosed technology can further perform a step of comparing the key patent entered from the user with the other key patents stored in the database and extracting the association with each other. 2, the technical valuation system includes a step of inputting the document information of the core patent and the previously stored core patent, the step of confirming the semantic information of the inputted document information, Determining relevance ranking based on the search result, and outputting the list according to the relevance ranking.

The technical valuation system may input the keyword described in the specification in the step of inputting the document information of the core patent and the pre-stored core patent as document information. For example, words included in the claims or the detailed description of the invention may be entered. In addition, it is also possible to enter further information of the IPC or other bibliography for technical classification of the application specification.

On the other hand, in extracting a plurality of keywords as described above, the technical value evaluation system formats connection relationships between respective keywords using an ontology module. Here, the ontology module is included in the technical value evaluation system for performing the above-described machine learning technique, and is used for grasping the relationship between the keywords based on the position where each keyword is placed in the sentence. The detailed description of the ontology will be omitted since it is already known through the relevant technical field.

Meanwhile, in the step of confirming the semantic information of the inputted document information, the semantic information of the inputted document information is confirmed. Here, the semantic information includes the type and attributes of the keyword. In one embodiment, the technology valuation system may determine whether the keyword is a noun, a verb or an adjective, and determine whether the keyword is a plural or homonym including a plurality of meanings.

Furthermore, it is possible to grasp the relationship between the keywords based on the position where each keyword is placed in the sentence. For example, if the keyword a is the subject of a sentence, the extracted keyword b may be a keyword describing or modifying the keyword a. The sentence in the specification necessarily encourages the use of unambiguous expressions in the relationship of spellings and formulas, and it is encouraged to make it as easy to understand as possible, so it is enough to grasp this semantic information through the system Do.

In a step of searching a database storing at least one core patents, a database storing at least one core patents included in the technology valuation system is searched. By using the database pool mentioned above with reference to FIGS. 3 and 4, core patents can be efficiently retrieved.

In the step of determining the relevance ranking based on the search result, the relevancy ranking is determined based on the search result. The technology valuation system evaluates its ranking according to the degree of relevance to the patent to be evaluated.

In the step of outputting the list according to the order of association, the list is output based on the result of calculating the association. The technical valuation system may provide the list to the user to provide the results of the relationship between the subject patent and the core patent and the basis on which the association is derived according to a predetermined form. As described above, it is possible to utilize as a more objective data for evaluating the market value of the core patent based on the step of extracting the relation between the core patents.

Meanwhile, the technology valuation system according to an embodiment of the disclosed technology can advertise or advertise the evaluation target technology based on the comparison result with respect to the evaluation target technology. That is, the user requesting the evaluation of the evaluation target technology can advertise or promote the evaluation target technology on the basis of the result of the comparison with the template or the core patents provided from the technical value evaluation system, and obtain the predetermined benefit therefrom Do.

For example, if the user is the owner or transferor of the technology to be evaluated, it can be used as data for concluding a technology transaction or licensing. Therefore, more reliable technical value evaluation can be performed through the technical value evaluation system, and advertisement and promotion of the evaluated technology can be performed.

Although a method for evaluating the market value of a core patent according to an embodiment of the disclosed technology has been described with reference to the embodiments shown in the drawings for the sake of understanding, it is merely an example, and a person skilled in the art It will be understood that various modifications and equivalent embodiments are possible.
