"They provide very thoughtful, sound legal advice. They are very responsive, and unafraid to challenge the client's incorrect information. I prefer that outside counsel be very direct and provide unvarnished advice."

"Takanori Abe demonstrated an excellent command of the law and a practical understanding of the courts.  Tremendous amount of experience."

"Takanori Abe is an accomplished and tenacious litigator.  What's great is that he is willing to go up against the major Japanese pharma companies which most Japanese firms won't do."

Case studies demonstrate that the team successfully managed an invalidation action and a patent opposition at the Japan Patent Office on behalf of pharmaceutical clients.
