We have accumulated vast knowledge and experience in almost all legal areas responding to the demand of our clients.  

Our specialties are in corporate business restructuring and intellectual property areas. We have dealt with a number of large scale and hard-fought insolvency cases and patent infringement cases, in which we have brought successful outcomes. In litigious matters, we approach them with determination and passion to "win", because of which our clients are fully confident in us. We set up Intellectual Property Division so that we can handle applications and prosecution services in various technology fields. Also, Legal Division and Intellectual Property Division work together so that we can provide one stop service from application to litigation in the field of intellectual property, especially patent and trademark.

In response to the increasing and diverse legal risks that business corporations face, we have been expanding our practice areas. Our attorneys at law and patent attorneys are studious and keen to learn new laws and practice areas so as to deal with the latest need of our clients. We are determined to provide the best service to our clients in fast changing business and legal environment.
