Description

[0001] The present invention relates to a method for analyzing promising technologies using patent information,

The present invention relates to a method for searching for a promising technology group that can prevail in the market in the future using patent information, more specifically, by performing quantitative empirical analysis using patent information, The present invention relates to a method of analyzing a promising technology group using patent information configured to be useful for establishing a strategy for future new technology development and setting a research and development direction.

Further, in order to solve the problems of prior art analysis methods using conventional patent information, in which a search method of a promising technology group using patent information is not presented in the field of lipid resources in the related art, The technology scope is defined by IPC (International Patent Classification) code, and the prospect index and convergent index for each technology group are derived by reflecting the recent trend of technology convergence and diffusion, And a method for analyzing a promising technology group using patent information.

In recent years, as technology gap between developed and emerging countries has narrowed gradually, the need to search for future technology that can lead the technology flow and create a market in each country has become a necessity. Therefore, a promising technology Has become a major task of science and technology R & D strategy.

In accordance with these trends, in each science and technology field, we are discovering and presenting various future vision for new business that can create new value. However, it is not easy for companies to find promising technologies in their own fields in all fields. The difficulty is also the biggest obstacle to the promotion of new businesses.

In particular, research in the field of geological resources has a wide range of demand, not only directly and indirectly, but also includes research from diverse fields ranging from basic research to applied research, and it is difficult for the private sector to undertake R & D. It is important to set the direction of future R & D centered on the center, and under the recent policy direction, there is a need to contribute to the creation of new markets for related industries.

As a result of this need, research on future technologies in the field of geological resources has been steadily continuing at the government level. In addition, the Korea Institute of Geoscience and Mineral Resources, which is in charge of R & D in domestic geological resources in the public sector, Has been steadily performing.

However, research on promising technologies in the future requires a steady study to reflect the social environment. In other words, the most important consideration in future promising technology research is the convergence and diffusion of technology, and recent trends in R & D in the field of geological resources The need for creative innovation and convergence is further emphasized.

Geological resource technology has traditionally focused on research and design for efficient use of land, exploration and development of resources, technology for recycling and recycling of resources, and technology for reducing risks from natural disasters. Recently, however, With the rise of environmental issues globally, knowledge and technology that support sustainable development in the Earth system, in which materials and energy circulate in addition to existing geology and resources, have emerged as major research topics in the field of geological resources. In particular, The development of new technologies through technology convergence and the creation of added value have been emphasized in various fields such as R & D in the field of geological resources.

As a result, developed countries such as the US, Europe, and Japan are accelerating investment in convergence technologies and market preemption to secure national competitiveness. Under these circumstances, there is a growing need to search for promising technologies for establishing research and development directions in the field of future geological resources have.

In other words, the search process of promising technologies can be generally divided into qualitative methods, which mainly use expert groups, and quantitative methods, which use R & D performance indicators such as patents and papers. Qualitative methods and quantitative methods are mutually complementary It can be used with an enemy relationship.

Here, a method of using patent data has been proposed as a representative measure for quantitatively measuring the performance of technology development.

In other words, patent data is that when a patent is filed as a patent, it is managed privately in order to avoid disclosure to the public, and that it is difficult to know which of the more economically important patents is different when comparing different patents However, it is expected to be useful for raising the efficiency of promising technology and establishing judgment criteria because relatively objective result can be derived.

More specifically, as an example of the prior art relating to the information retrieval method using patent data as described above, for example, in Korean Patent Registration No. 10-1229520, a patent information database having a patent document, An expert database having expert information according to patent classification codes of keywords and search keywords, a search unit for searching patent documents and expert information according to search keywords, a search unit for merging the searched patent document information and expert information into one, And a page generating unit for providing the search results to the client. When searching for patent information by keywords, the search result and the expert information about the result are found, and after matching with the search result, the search result is provided to the searcher, Patent information retrieval system configured to provide patent service It has presented the technical information bar.

Further, according to another example of the prior art relating to the information retrieval method using the patent data as described above, for example, in Korean Patent Registration No. 10-1126699, a patent document and a plurality of For a plurality of patent cases stored in a patent source database storing bibliography containing at least one theme code having a lower classification value, the bibliographic information of the individual patent cases may be classified into at least one And a central control server for providing search result data to the patent request corresponding to the search request word when the search request word for patent search is received, Patent information data of a specific patent database can be searched from various perspectives on the user side It has been suggested by the description of the patent analysis system and method for generating research ideas that are configured to obtain an accurate patent information data.

Another example of the conventional technology related to the information search method using patent data as described above is disclosed in Korean Patent Registration No. 10-1054824, for example, in which an initial keyword is input from a user to retrieve a patent document A keyword extracting unit for extracting keywords defined on the searched patent document, and integrating a first keyword and a second keyword to form a keyword list; A patent document clustering unit for forming a matrix by determining whether each keyword included in the keyword list is found for a patent document retrieved through the keyword extracting unit, and clustering the patent document; A semantic network constructing unit for extracting a common keyword among keywords belonging to a plurality of patent document clusters generated through the patent document clustering unit and setting the new keyword as a new node and setting a patent document cluster including the remaining keywords excluding the common keyword as a lower node; After searching the frequency included in the patent document communities and the patent application date of the patent document for each node set through the semantic network constituent unit, the frequency value and the patent application date value are set to an arbitrary axis (x, y) And a patent map construction unit for constructing a patent map by displaying the semantic network on the coordinate plane according to the x and y values of the respective nodes, so that the patent information can be visualized on the basis of the keyword. The technical contents of the visualization system and its method have been presented.

Further, as another example of the related art related to the information retrieval method using the patent data as described above, for example, in Korean Patent Registration No. 10-0899754,

From the large amount of patent publication data periodically registered to be connected to a plurality of user terminals via an online network, data serving as a reference of the technology evaluation is extracted by using a text mining technique, The patent data are derived and analyzed to construct the base patent data, and the user is asked to evaluate the registered patent through the online network using the user terminal, and analyzed using the text mining technique. Then, A technology evaluation system of a registered patent using a text mining technique configured to extract similar patents, to perform evaluation with various evaluation items for each kind of factor, and to feedback the result to a user through a user terminal And the like.

As described above, conventionally, various methods of providing information to a user using patent information have been proposed. However, in the conventional methods as described above, most of the patent documents related to the keyword input by the user are searched In addition, there is no description of technology contents that can predict and present promising technologies for setting future R & D direction using patent data.

In particular, in the field of geological resources, there is a growing need for searching for promising technologies for setting future research and development directions. However, the above-described methods using patent information of the prior art are not suitable for searching for promising technologies in the field of geological resources There was no way to do that.

Therefore, it is necessary to search and present the patent literature related to the keyword inputted by the user simply as described above. In particular, the patent data in the field of geological resources are used to predict and present promising technologies for setting future R & In order to solve the problems of information providing methods using patent information of the prior art, which have not been proposed for the technical contents that can be provided, it is necessary to quantitatively measure the achievement of technology development using patent information and to derive a promising technology objectively It is desirable to provide a method of analyzing a promising technology group using a patent information of a new configuration. However, a device or a method that satisfies all of the requirements has not yet been provided.

Hereinafter, with reference to the accompanying drawings, a description will be given of a specific embodiment of a method for analyzing a promising technology group using patent information according to the present invention.

Hereinafter, it is to be noted that the following description is only an embodiment for carrying out the present invention, and the present invention is not limited to the contents of the embodiments described below.

In the following description of the embodiments of the present invention, parts that are the same as or similar to those of the prior art, or which can be easily understood and practiced by a person skilled in the art, It is important to bear in mind that we omit.

That is, according to the present invention, as described later, by conducting quantitative empirical analysis using patent information, it is possible to find a promising technology group that can prevail in the market in the future, And a method for analyzing a promising technology group using patent information configured to be useful for setting a research and development direction.

Next, with reference to the drawings, a description will be given of a method of analyzing a promising technology group analysis method using patent information according to the present invention.

In general, the search process of promising technologies can be divided into qualitative methods that utilize expert groups and quantitative methods that use R & D performance indicators such as patents and papers. Qualitative methods that utilize expert groups are analyzed through quantitative data It can be evaluated from a comprehensive point of view, and it is advantageous to use the knowledge of experts accumulated through long learning and experience relatively efficiently. However, if the number of experts is small, It is difficult to draw consensus among experts and there is a possibility that the efficiency may be lowered. Also, it is difficult to evaluate a large amount of technology as a professional questionnaire, and the prediction by a professional group tends to show conservative results that are somewhat risky Future technology by experts group The seat limit has been raised.

In recent years, quantitative analysis methods such as Knowledge discovery in database (KDD) / Knowledge mapping (KM) and Bibliometrics have been used in addition to a typical expert group, One of the data is patent data.

In other words, patent data generally contain specific information on research outcomes, provide monitoring tools that can identify trends in technology development, track technology knowledge, technology, technology and industry knowledge flows In particular, it is possible to systematically classify and search through the International Patent Classification (IPC), which is an international patent classification, and the information format is standardized, thereby making it possible to efficiently use the patent documents in the world.

Therefore, patent data is one of the most widely used data for analysis of international competitiveness of specific technology field, effect of technology development, and analysis of the spread of technology development, and it is expected that patent data can be used to search for promising technology group.

That is, referring to FIG. 1, FIG. 1 is a diagram schematically showing the overall configuration of a prospective technology group analysis method using patent information according to an embodiment of the present invention.

As shown in FIG. 1, a method for analyzing a promising technology group using patent information according to an embodiment of the present invention includes a step of defining an analysis target technology group through a prior art investigation, The patent information database for quantitative analysis is searched for by searching patent information on the patent information database, the patent information database constructed in the step is used to calculate a prospective index and a fusion index, And deriving a promising technology group based on the fusion index.

Here, the promising technology to be analyzed in the present invention means a technology that has a high demand for future technology development and a high degree of expectation of convergence into the industry.

That is, as shown in FIG. 1, the flow of analysis for deriving a promising technology group of a promising technology group analysis method using patent information according to an embodiment of the present invention is as follows. First, In this case, the prospective index is determined by the weight of the normalized number of patents and the patent growth rate, A series of processes for deriving a future promising technology group by considering both the obtained prospect index and the fusion index can be configured to be executed by a computer or dedicated hardware.

More specifically, firstly, a prior art investigation for defining a technology group to be analyzed to derive a promising technology group will be described. In order to define a technology group of interest in the IPC, prior art should be investigated, , There is a method of searching a keyword or searching a classification that is judged to be directly applicable in the IPC.

First, keyword search refers to search of a specification by a combination of words, and is widely used as an investigation method of the prior art. However, the keyword search is difficult to apply directly to the present invention due to the following disadvantages.

First, there is a requirement that the keyword search should be familiar with the creation of keywords according to each technical field, that is, for example, the machine should include keywords appropriate to the device or structure, , It is difficult to obtain desired search results unless they are familiar with the detailed technology of each field.

Second, it is necessary to consider both synonyms and dialects in the nature of the language. That is, it is necessary to consider all the expressions used in related fields of each technology, and the expression in terms of history and society may be changed according to the change of time. You have to think about a lot of expressions about.

Here, in particular, since the technology in the field of geological resources encompasses a wide range of technologies from the basic science to the application field, it is highly inefficient to select a wide range of technologies such as the geological resource field by keyword search .

Also, there is the following problem when searching IPC directly.

First, in order to know and classify the IPC accurately, it is required that the user fully understand the IPC classification system such as, for example, the characteristics of each category, classification principle of application and function.

Secondly, since there may be a plurality of IPC codes related to one technology, it is necessary to review all the adjacent classifications without limiting to a specific category. However, There is a need to reduce the scope of the analysis.

Therefore, for more efficient prior art research, it is necessary to complement the advantages and disadvantages by appropriately combining the two methods of keyword search and IPC search described above.

That is, the step of defining the analysis target technology group and the step of building the patent information database may be performed by performing a prior art search using a keyword search or an IPC search, For example, an IPC code), and collecting patent information corresponding to a defined technology group (IPC code) and constructing the database as a database.

Next, calculation of promising indices and fusion indices will be described.

First, the step of calculating the prospective index will be described. The prospective index (PI, Promise Index) shows how active the technological development activity in the relevant field is taking place by using the number of patents and the patent increase rate, Based on the results of the survey.

In other words, the prospect index (Π) indicates the degree to which the future market superiority is expected based on the level of technology development activity in the relevant field, and can be expressed as the following equation (1).

[Equation 1]

In Equation (1), A _i represents the number of patents of the technology group i, B _i represents the patent increase rate of the technology group i, and λ represents the weight between the patent number and the patent increase rate.

More specifically, the prospective index is determined by three factors, A _i , B _i , and λ. At this time, the patent number A _i may vary due to differences in technology development activities, The degree of occurrence may vary.

Therefore, in the present invention, in order to minimize such a deviation, when comparing the average size of the prospective index in the analysis results with reference to the literature of the prior art, a value obtained by taking 1/4 power which is a relatively valid value is used.

Also, in the present invention, a value obtained by normalizing the number of patents corresponding to each technology group using the maximum value and the minimum value of the patent number in the field is used, and thus the finally obtained promising index is expressed by the following equation (2) , As shown in Fig.

&Quot; (2) "

In addition, the weight λ indicating the weight between the number of patents and the rate of increase of the patent has a value between 0 and 1. In order to determine such a weight, the prior art (3), 93-116, 2006), we select a technology group that is considered to have an advantage over the current technology, We applied the method to the selection of technology.

In addition, the patent growth rate B _i is calculated by comparing the final year with the average number of patents over the three years excluding the previous year by referring to the European innovation scoreboard, which is evaluated annually by evaluating the degree of innovation of EU countries at the European Commission Joint Research Center Respectively.

In particular, in the 'European innovation scoreboard', only 200% of patents with a patent increase rate of 200% or more were recognized, which means that even if the number of patents is small, the increase rate may increase significantly This is to prevent distortion.

The convergence index indicates the degree to which a specific technology fuses with another region. The convergence index is determined using the degree to which the technology group is classified into different regions under different classification systems do.

At this time, the fusion index has a value between 0 and 1 depending on the field to be fused, and this value is relatively determined according to the range of the technical group to be compared.

Further, the primitive fusion index FI ₀ can be calculated by the following equations (3) and (4).

&Quot; (3) "

&Quot; (4) "

Here, F _max means the total number of classifications in the classification system, and F _c means the total number of classifications in which one technology can be classified under another classification system and has a value between 1 and F _max .

Also, F _{0, which} is calculated by the reciprocal of lnF _max , serves as an adjustment factor to set the maximum value of the primitive fusion index FI ₀ to 1.

That is, it can be seen that the primitive fusion index computed as described above is defined such that the difference between the lower and higher technical convergence degrees is defined to be larger and the difference to the higher is less.

At this time, also for the fusion index, as shown in the following [Equation 5], the technology fusion index normalized by using the maximum value and the minimum value is obtained in order to match the prospective index with the normalization level.

&Quot; (5) "

Here, FI _i represents a fusion index of the technology i, which is a value obtained by normalizing the primitive fusion index, FI _{0i that} is not normalized represents a primitive fusion index of the technology i, and Min (FI ₀ ) represents a primitive fusion index And Max (FI ₀ ) means the maximum value among the primitive fusion indexes of the target technology group.

Therefore, the technology convergence index is relatively determined according to the range of the defined technology group. Finally, the promising convergence technology is highly likely to converge in various fields while taking into consideration both the above-mentioned promising index and convergence index, This is a group of technologies that are expected to be.

That is, the step of deriving the promising technology group may include the steps of: determining whether the prospective index and the fusion index are both equal to or more than a predetermined standard on the basis of the prospect index and the fusion index calculated in the manner described above, , And a process of selecting a technique in which both the prospective index and the fusion index dominate, such as up to a specific rank according to the relative ranking, is selected by the promising fusion technique.

Therefore, it is possible to implement a method of analyzing a prospective technology group using patent information according to an embodiment of the present invention as described above, and then, a prospective technology group analysis method using patent information according to an embodiment of the present invention, In order to verify the group analysis method, a search result of a promising technology group in the field of geological resources will be described by using a promising technology group analysis method using patent information according to an embodiment of the present invention.

In other words, for the empirical analysis, the technology of the geological resource field must first be defined and classified. In the present invention, the technology is defined based on the IPC.

More specifically, the IPC is composed of 8 sections and 130 classes, 639 sub-classes, 7,402 main groups, and 64,332 sub-groups as of 2015. In the present invention, Respectively.

In addition, the World Intellectual Property Organization (WIPO), which provides IPC, officially provides technical classification as 'IPC - Technology Concordance Table', which reclassifies IPC by technology sector. In this classification table, Since it is not clearly defined, it is necessary to select the technical field of interest among the IPC classes prior to analysis and define it as a geological resource field.

Therefore, the prior art survey should directly examine the IPC classification considered to be applicable to the geological resource field, but the Korean mineral resources corporation, the Korea National Oil Corporation, the Korea Coal Corporation, etc., The technical group was classified by referring to the list of patents having the major public institutions in the field as applicants.

That is, referring to FIG. 2, FIG. 2 is a classification chart of main technical groups in the geological resources field, which is a table showing the technical group classified as having high relevance to technology development in the field of geological resources based on IPC as described above.

In addition, the patent data for finding promising indices and convergence indices are based on the patent application date, and the DB was constructed using the patent cooperative treaty (PCT) application data from 2009 to 2013.

Here, the patent application by the PCT is a system in which the applicant designates the country to receive the patent in the patent office of the home country, and when the PCT international patent application is submitted, the patent of each country is recognized as a domestic application. It is useful for analyzing international technology trends or searching for promising technologies because it has a relatively high level of patents and high objectivity compared to patents filed by national or regional patent offices.

In addition, IPC-KSIC (Korea Standard Industry Code) linkage table was used as the classification system for obtaining the convergence index. That is, the IPC-KSIC linkage table uses the citation relation of the patent and utility model application in Korea The IPCs used in the literature of the prior art are classified according to the field classification reclassified according to the industry, and therefore, It can be said that the classification suitable for domestic promising technology is used.

Next, the results of the empirical analysis for deriving the promising technology based on the above-described technical classification will be described.

First, the promising exponent analysis will be described. As described with reference to Equations (1) to (5) above, the weight λ for obtaining a prospective index is expressed by the following equation And selecting a technology group that is judged to be in the high technology category and applying the weight to the high technology category in future technology selection.

However, in this case, randomness can be involved in selecting a technology group that is currently dominant. Thus, in the present invention, based on the domestic patent data, Weights were chosen to make them appear higher.

That is, among the 31 technology groups mentioned in the table shown in FIG. 2, technology groups that are active in technology development are selected based on the domestic patent data, and a weighting factor λ that maximizes the minimum value of the prospect index of the selected technology groups is calculated. The weight thus calculated is 0.72.

In addition, if weights are obtained by using this method, if the promising indices are obtained using PCT international patent application data, it is possible to analyze international trends of technology development, but it is possible to improve the problem that the level of domestic technology development is not considered in deriving promising technologies It is expected to be.

That is, referring to FIG. 3, FIG. 3 is a table showing promising indices according to technology groups derived as described above.

In FIG. 3, the average of the promising indices of the 31 technology groups to be analyzed is 0.4084, the average of the promising indices of the upper 50% technology group is 0.5691, the average of the promising indices of the lower 50% technology group is 0.2578, G06F, G06Q, G01N, H01M, E21B, B01D, B65D, C09K, C01B, C02F, G01B, G01C, B22F, C04B are the top 50% candidates of the candidate group.

In particular, the promising indices of the G06F, G06Q, and G01N technology groups related to resource exploration and measurement, surveying, and material investigation and analysis were analyzed to be high, and the H01M prospect index related to the conversion of electric energy And it was also analyzed that the promising index of the technology group related to the processing of resources was also high.
