Referring to FIG. 1, a patent analysis system 10 according to the present embodiment includes a DB control unit 11, a user interface 12, a patent DB 13, and an analysis DB 14. The patent analysis system 10 may be connected to the user terminal 15 directly or through a network and a user DB 16 may be connected to the user terminal 15. [

The user of the user terminal 15 can access the patent analysis system 10 through the user interface 12 and use individually refined patent information data. The data of the patent DB 13 and analysis DB 14 can be processed through the DB control unit 11 and can be provided to other users through the user interface.

More specifically, the DB control unit 11 analyzes a keyword for search for each patent information acquired from an external patent database in which a plurality of patent information is stored and accessible through a network, (Patent DB or the like), and stores the reference table for the dispute evaluation score in which the evaluation items of the respective patent information are weighted, in the storage unit. If a first keyword is inputted through the user interface or a selection signal for a specific analysis target is input, the DB control unit 11 acquires a plurality of keywords from the patent database 13 using the first keyword or the keyword for searching the analysis subject The patent information is searched, and the upper group is extracted from the search results according to the order of high degree of match of the claim range. The sum of the dispute evaluation scores (that is, the risk level) for each patent information of the upper group is calculated by referring to the reference table Converts at least some of the patent information of the upper group into a predetermined output format according to the risk. The converted patent information is outputted through the user interface 12 according to a predetermined output format.

The DB control unit 11 executes the above-described series of procedures by executing a program stored in the recording medium, which is connected to the computer apparatus itself or a recording medium on the network. A program refers to software stored as computer readable instructions in a series of the above-described patent analysis procedures. The DB control unit 11 may be implemented as a microprocessor or the like.

The DB control unit 11 may include a keyword analysis unit 111, a search unit 112, an extraction unit 113, a risk calculation unit 114, and an output control unit 115 as shown in FIG.

In the DB control unit 11 described above, the keyword analysis unit 111 analyzes a keyword for each patent information acquired from a patent database in which a plurality of patent information is stored and accessible through a network. The keyword analysis unit 111 may analyze the search keyword in all items of patent information accessible through the network. However, the keyword analysis unit 111 is not limited to this, and may include a specific item of the patent information, invention, Abstract, and Claims of the present invention.

The analysis of the keyword for search can be performed using an analysis module provided independently according to the type of characters (Korean, English, etc.). For example, a morpheme analyzer can be used to analyze a keyword for searching in Korean patent information. A morpheme analyzer refers to a means or component for analyzing a morpheme, which is the smallest unit of meaning in a sentence. In this embodiment, the morpheme analyzer may be a unit for analyzing and extracting a word or part of a word (a word) in a sentence or a unit performing a function corresponding to the means.

Kind Korean Morpheme Analyzer (KKMA), MACH etc. can be used as the morphological analyzer. But the present invention is not limited thereto, and a morpheme analyzer commercially or separately manufactured can be utilized. In addition, it is possible to use a part (phrase) of a compound noun or a compound noun that has not been analyzed as a unit noun in addition to the unit noun according to the morphological analyzer to be implemented.

The keyword for analysis analyzed by the keyword analysis unit 111 may be separately stored in the storage unit. Here, the storage unit may be implemented as a storage device connected to the patent DB 13 or other DB control unit 11, and the storage device may include a storage device such as a cloud system connected to the patent analysis system through a network at a remote location . If the keywords for search are stored on a separate basis, not only the patent analysis time can be greatly shortened, but also the patent analysis can be efficiently performed and the information analyzed by the patent can be easily utilized. In particular, if keyword analysis is performed for all patent information that can be accessed through a network in a normal time without carrying out patent analysis, it can be usefully used for a patent analysis service for real time disputes over a network.

In the present embodiment, the storage unit stores a reference table for the dispute evaluation score, to which the evaluation items of each patent information are weighted. The reference table is for weighting the evaluation items of the patent information and assigning all or a part of the weights to the patent information according to a predetermined evaluation criterion. Here, the evaluation criterion refers to the degree of agreement with respect to the first keyword or the like from the user terminal and the search keyword in at least one evaluation item, but is not limited thereto.

When a selection signal of specific patent information (analysis target) or a predetermined first keyword is input through the user interface 12, the retrieval unit 112 retrieves a first keyword or a keyword for a specific analysis target (Hereinafter, referred to as 'second keyword') to retrieve a plurality of patent information stored in the patent DB 13. Here, the first keyword may be a keyword of a specific analysis target, or may be an arbitrary keyword for a separate product desired for patent analysis.

In order to search for patent information with potential conflicts from a plurality of patent information, the search unit 112 compares the first keyword or the second keyword with each search keyword of a plurality of patent information, Record the agreement.
