Who We Are

ADACHI INTERNATIONAL PATENT FIRM (now NAGOYA INTERNATIONAL PATENT FIRM) was founded in 1978 by Chairman Tsutomu Adachi. Since then, our faithful service and untiring dedication have permitted us to enjoy the patronage of not only many domestic clients but also clients overseas. In January 2007, the firm was incorporated under the current name, NAGOYA INTERNATIONAL PATENT FIRM, in order to better serve our clients and meet the needs for a highly specialized and sophisticated professional service in the field of intellectual property.

To protect and promote effective utilization of valuable intellectual property of our clients, we are able to provide a wide scope of services from the preparation and prosecution of all types of patent and trademark applications, and representation in appeals and trials, to the peripheral practice related to intellectual property, like expert opinion (e.g. non-infringement or invalidity), contract negotiation (e.g., preparation/negotiation of license agreements, technology transfer agreements, non-disclosure or development agreements), portfolio management strategy, litigation and ADR.

Our long-term cooperation with foreign associates has enabled us to help our clients secure intellectual property as well as enforce their intellectual property via license negotiation or initiating a lawsuit overseas. Further, we have handled numerous litigation and trial cases among other Japanese patent firms. In addition to our Japanese patent and trademark attorneys, U.S. patent attorney further enhances our ability to promptly respond to clients' request regarding IP disputes.

In order to better provide a wide range of services, the skills of our members are very diversified, including: patent and trademark attorneys, technical engineers, design & trademark specialists, translators, draftspersons, and clerical staff for domestic and foreign cases, a total now of over 80 people. The specialties of our engineers are well balanced covering the fields of mechanical engineering, electrical and electronic engineering, chemistry/biotechnology and physics. This allows us to provide our clients with sufficient service in a wide range of technical fields. Each one of us strives to improve our skills through internal and external (technical and legal) training programs on a daily basis so that we are always ready to fulfill the needs of our clients upon request.
