We provide robust representation in patent infringement litigation, patent invalidation trials, and litigation to overturn JPO trial decisions. Our expertise also extends to disputes involving designs, trademarks, copyrights, and the Unfair Competition Prevention Act.

In addition to litigation, we assist clients in the strategic issuance of warning letters for infringement. Conversely, we also provide defense and counsel for clients who have received such notices regarding patents or other intellectual property rights.

We render expert legal opinions regarding the likelihood of infringement and patent validity.

For patent holders concerned about third-party infringement, we draft comprehensive opinions asserting validity and infringement. For those accused of infringement, we provide opinions asserting non-infringement or invalidity to support a robust defense. Our team also has a proven track record in complex matters, including statements on the effects of patent rights regarding term extensions for major pharmaceutical manufacturers.

Furthermore, leveraging our deep understanding of the adjudicator’s perspective, we offer expert opinions and evidence collection regarding “prior user rights” and “public use,” as well as interpretations of laws and other specialized documents related to patent law and general IP matters.

We offer advisory services through monthly retainer agreements. This arrangement allows clients to seek legal advice freely without the need for individual quotes or billing for each consultation.

By maintaining continuous engagement, we cultivate a deeper understanding of our clients’ business activities, enabling us to provide higher quality, proactive legal support tailored to their specific needs.

Beyond litigation and opinions, we provide comprehensive consultation on matters related to patents, designs, trademarks, copyrights, and the Unfair Competition Prevention Act.

Our services include assisting companies in developing internal IP policies and governance rules, as well as delivering lectures and seminars. We provide holistic support to ensure the smooth and legally sound operation of our clients’ businesses.

Furthermore, led by Representative Attorney Ryuichi Shitara, we are actively engaged in the field of international arbitration, serving as arbitrators and expert witnesses. We are committed to contributing to the proper resolution of cross-border civil disputes by acting as counsel in international arbitration, extending our expertise beyond IP litigation. Additionally, leveraging his extensive judicial experience, Mr. Shitara serves as a mediator in court-based IP mediation proceedings. He intends to continue handling a broad spectrum of such mediation cases to facilitate effective dispute resolution.
