Searches and Opinions

Global enterprises need to work with cultural and linguistic nuances in order to make clear, informed decisions on how they will develop and promote their intellectual property rights-—not only for specific applications but also to expand markets and negotiate in international business and legal cultures.

Keisen Associates specialists conduct searches not only in order to prosecute applications for IP rights, but also to enable you to engage and expand effectively in Japan’s market before and after filing. We can navigate what kind of IP a design of sorts may entail, or the thorny issues of searching for a litigation trail.

Our in-house researchers utilize online databases from relevant industries and the press, as well as journals and other technical publications, to conduct prior art, market clearance, and legal status searches. Of course, we can investigate the archives of the Japan Patent Office to provide legal status information on registered, expired, and pending patents and trademarks, as well.

As one of the few native Japanese IP law offices in the U.S., our Philadelphia office staff is uniquely staffed to assist our clients personally concerning the complex rules of Japanese intellectual property law. Aside from consultations, we also prepare expert opinions on prior art and patent validity and infringement assessments, in collaboration with our attorneys in Tokyo, for our clients.
