Referring to FIG. 4, the noise removal and effective patent determination steps of step S200 will be described in detail.

4 is a detailed flowchart of noise removal and effective patent determination steps according to an embodiment of the present invention.

The noise removal module 210 reads the patent classification from the data information for patent analysis and calculates the number of searches for each patent classification (S202).

For example, the technology related to automobile door handles is distributed in the patent classification such as E05B, B60R, B60J, E05C, B60Q, G07C, E05F and G06F at the class level of the International Patent Classification (IPC) It is estimated how many data are distributed by the patent classification.

In the present embodiment, the number of searches is calculated at the class level in the international patent classification. However, the present invention is not limited to this, and it is also possible to calculate the number of searches in various hierarchical structures such as sections and subclasses, It is also possible to estimate using the cooperative patent classification (CPC) or other patent classification.

The noise removal module 210 calculates the increase / decrease ratio after rearranging the calculated number of searches in a descending order (S204).

The noise removal module 210 performs a first filtering process for determining patents belonging to a patent classification in which the number of searches per patent classification is drastically reduced or a patent classification in which a rate of increase / (S206).

For example, when the number of searches and the increase / decrease rate of the technology related to the automobile door handle are as shown in the following Table 1, the noise removal module 210 detects the number of searches and the increase / decrease rate from B60R However, it is preferable to hold the effective patent broadly, so that the increase / decrease rate is not rapidly decreased, but the noise can be judged from G07C in which the number of searches is sharply reduced.

IPC Search Increase / decrease rate E05B 678 0 B60R 283 -58.20% B60J 244 -13.80% E05C 117 -52.00% B60Q 115 -17.40% G07C 69 -40% E05F 65 -58.00% G06F 50 -23.10%

The noise removal module 210 reads backward citation information, forward citation information and inventor information from the first filtered filtered ROI using the patent classification (S208) .

The noise removal module 210 replaces the citation relation for each patent number with the citation relation for each inventor (S210).

For example, US8851720, which is one of data files, is connected to US7533664 as prior art citation information and US9102266 as post-application cited information. As shown in the following Table 2,

First-aid citation information Data Application Information MISAWA AKIHIRO Lee Jae Kyu DINGMAN DAVIDA

The noise removal module 210 performs a network analysis using the replacement relationship information of each inventor and calculates a centrality (S212).

Although the network analysis according to the present embodiment is calculated using a known network analysis program (e.g., NetMiner) and the centrality is used as a filtering factor, the present invention is not limited to this, and the cluster coefficient It is also possible to use it as a filtering factor.

The noise removal module 210 performs secondary filtering to select the inventor's patent having low centroid and judge it as noise (S214).

The noise removal module 210 recognizes the summary data of the first filtered filtered data using the patent classification (S216).

In this embodiment, the noise canceling module 210 recognizes the contents of the summary in order to recognize the contents of the description, but the present invention is not limited thereto, but may recognize the contents of the claims or the detailed description of the invention.

The noise cancellation module 210 removes a stop word that does not affect the technical meaning from each summary and generates a document-text matrix (DTM) (S218).

The document-term matrix is defined by vertically arranging the keywords used in each patent horizontally, as shown in [Table 3] below. Means a matrix that counts the frequency of appearance of keywords for each patent.

door handle vehicle One 0 0 9 2 8 6 2 3 11 2 4 4 One 4 3

The noise removal module 210 performs similarity analysis for each patent using the document-term matrix (S220).

In this embodiment, similarity analysis for each document uses cosine similarity, but the present invention is not limited thereto.

In step S222, the noise removal module 210 performs third-order filtering to select a patent having a low similarity value and to judge the noise based on the similarity value for each patent.

As described above, the noise removal and effective patent determination step (S200) according to the embodiment of the present invention can increase the reliability of filtering by removing noise from the viewpoint of the patent classification, the inventor, and the technical content.

The key patent selection step S400 will be described in detail with reference to FIGS. 5 and 6. FIG.

FIG. 5 is a detailed flowchart of a core patent selection step according to an embodiment of the present invention, and FIG. 6 is a graph illustrating a relationship between opportunities and risk for selecting a core patent according to an embodiment of the present invention.
