About us

Supporting your intellectual property protection through our experience and technical knowledge.

Senior Partner

Nakajima & Associates IP Firm has been actively supporting the acquisition of intellectual property rights that are directly linked to our client’s profits ever since it was established in January 1985 as Nakajima Patent Attorneys Office.
In recent years it has become difficult for Japan to maintain dominance on a global scale due to the rise of emerging economies, including Asian countries such as China.
For a country with limited natural resources such as Japan, exercising intellectual property rights for a competitive edge has never been so important. However, simply acquiring a large number of intellectual property rights incurs correspondingly large costs, and may not be of direct benefit to our clients.
Our firm provides a variety of services to strategically acquire intellectual property rights in view of our clients’ business strategies and goals. We work in close cooperation with our clients, always keeping the interests and profits of our clients foremost.
In order to best support the acquisition of profitable intellectual property rights, our firm employs a highly professional team of skilled technical staff, translators who work in close cooperation with the technical staff, and administrative staff with detailed knowledge of legal systems worldwide.
Here at Nakajima & Associates IP Firm we can help you to acquire and protect effective and profitable intellectual property rights. Please do not hesitate to contact us should there be any way in which we can be of assistance.

Administrative Philosophy

We have the utmost respect for intellectual property,
fruit of the wisdom of humankind,
we strive to contribute to the development of industry and culture
by acquiring rights to the satisfaction of our clients.

Guiding Principles

1. We shall constantly strive to hone our skills as specialists in technology and law.
2. Our entire office staff shall work together as a team to ensure client satisfaction.
3. We shall strive to benefit the world around us through our daily endeavors.
