IP Litigation

Based on a wide range of experience, we provide multifaceted and strategic legal advice regarding domestic and overseas intellectual property disputes in various technology and industrial fields.

Nishimura & Asahi has extensive experience handling IT and IP-related lawsuits and disputes, including actions (both provisional injunctions and formal lawsuits) concerning the infringement of patents, trademarks, design rights, copyrights and rights under the Unfair Competition Prevention Act, and other IP rights; patents, trademarks and design invalidation procedures; and employee invention compensation cases. Many of these cases have been reported in law reports and by the media as important judicial precedents. Beyond representing our clients in litigation or other legal actions, we routinely provide strategic advice to our clients in pre-dispute cases. We also handle border enforcement actions against infringing products in Japan and other countries, and domain name disputes; and disputes relating to systems development. With ongoing globalization, IP-related lawsuits and other dispute resolution procedures are increasingly instituted across multiple countries and regions concurrently, and such procedures are often conducted by a variety of dispute resolution bodies. They may involve procedures in the United States, Europe and other jurisdictions, including patent infringement actions and ITC proceedings in the United States, nullification actions before the European Patent Office, and patent lawsuits in Germany. To handle such matters, Nishimura & Asahi has forged close connections with leading law firms and attorneys in various jurisdictions to ensure that such matters are conducted in close coordination with local counsel in the respective countries and jurisdictions involved.
