MeiYoSen is a corporate name dictionary created by KTS.

MeiYoSen is a cloud service for use to patent researches, analyses and so on by referring to corporate information which includes Applicant’s Identification number given by the Japan Patent Office, name, address, historical transition and corporate group.

MeiYoSen can “visualize” corporate information that changes due to the existence of fluctuations in name spellings, and name change, corporation merger & acquisition and corporate split-up.


Characteristics of MeiYoSen data creation 

MeiYoSen uses combination of “Applicant’s Identification number” and “Name” to create accurate and detailed information.

Different companies with the same name have been treated as the same company in many cases.

And the name of one company is sometimes spelled in several different ways, so the same company is treated as different companies.

For these reasons, there have been difficulties to accurately grasp the target company.

MeiYoSen makes it easy to distinguish companies, which cannot be identified only by the names, with the Applicants’ Identification numbers, and it is useful not only in patent researches and analyses but also in any scenes that utilize corporate information.


MeiYoSen’s Four Major Functions

1.Easy Search Operation







 2.Related ID

Related ID information can be shown as a list which tells the relations of different companies with the same name or the same company with different IDs etc. by using Applicants’ Identification Numbers.




3.Transitional Map 

Corporate transitional information since 1990 can be shown in map collected by our own research.






4.Corporate Group 

Corporate group information can be shown as a list which has a group corporate structure in hierarchy, indicating the relationship of a parent and subsidiaries, each business and so on obtained from our own research.





Scenes where MeiYoSen shines

 1.Patent search and research  

Improve research accuracy.

With MeiYoSen reviewing applicants obtained from a result of classification or technical term search, you can find objects that should be added, such as slightly different names and related group companies. Also you can find a different company with the same name. As a result, missing information and noise are reduced, which improves the quality of research.


2.Statistics and Analysis 

Improve reliability and understanding.

MeiYoSen allows to verify applicant’s information that is likely to be overlooked, so that you can create a statistic population set, which is critical in statistical analysis, with no missing information and less noise.

This will also help you understand the results of the analysis.


3.Marketing and Sales Activities 

Acquire highly accurate and systematic information.

Utilization of MeiYoSen is not limited to patent researches and analyses. By investigating the trends of competitors, it may be possible to obtain a fresh dimension in marketing and sales activities. Adding patent perspective with daily research activities will make you get a chance to find a breakthrough.


4.Corporate Management and Executive Meetings 

Expedite business decision

Transitional map clearly indicates corporate historical transitions of M&A and Split-up of a targeted company.

And corporate group information of a target company tells the relations of parent and subsidiaries either in or out of the industry segments.

Utilizing various information acquired by MeiYoSen in executive meetings and managerial decisions allows to gain effective business results even in a situation where quick and correct decision is required.
