Intellectual Property

From Patent Litigation to International Enforcement

We provide broad coverage — with a focus on representing rights holders, extending to the defense of accused infringers.

Patent litigation places a heavy burden of proof on the claimant, and the number of attorneys capable of taking on cases where a small or mid-sized company challenges a large corporation is extremely limited. Our firm has seen multiple such cases through to successful conclusions.

Where enforcement in Japan is difficult, we also look to rights enforcement overseas — including the United States — leveraging our global network of NPEs and Litigation Funds to build international enforcement structures.

Building international enforcement structures through U.S. litigation and collaboration with NPEs and Litigation Funds.
