Intellectual Property

Hands-on Experience is Worthwhile.

We simply believe that the most important feature of a successful intellectual property practice is the ability to properly evaluate and address abstract intellectual property-related issues. For example, we have to appropriately evaluate the scope of a client’s patent rights, the validity of a client’s patents in light of prior art, whether creations have originality, whether confidential information meets the definition of a trade secret and whether a trademark is confusingly similar to another, among other issues. Facts presented in court are usually not greatly in dispute between the parties, but their evaluation often varies from one practitioner to another. It is thus essential for us to leverage our real, hands-on experience in this field to correctly evaluate and solve these abstract issues.

We are trial-ready attorneys with extensive courtroom experience. Because we know how to present complex technical issues succinctly and in a way that appeals to judges, we are confident that we can provide our clients with the sophisticated legal analysis that they need in intellectual property transactions and to win in intellectual property litigation. Our expertise has led some of Japan’s leading corporations and growing companies to seek us out.
