Intellectual Property Professionals

Welcome to our website.
APERIO IP ATTORNEYS is an intellectual property law firm located in Tokyo, Japan.

Our commitment is to provide high-quality IP services using our global experience at a reasonable price. Our attorneys all have long experience in IP practice and have led many patent and trademark applications into allowance.

In addition to the traditional IP services, we also provide additional services to help our clients start their business outside Japan.

High-Quality Services

As you may know, not all Japanese IP firms provide high-quality service.

With regard to foreign-originated applications, a practitioner must know not only differences between Japanese language and foreign languages but also differences between domestic practice and foreign practice.

One of our partners, Tomohiro Mori, studied at a U.S. law school and lived in the U.S. for a while. His English skill is better than the average of Japanese IP attorneys. Additionally, he is familiar with foreign IP practice as well as Japanese IP practice because he worked at U.S. law firms and handled many foreign cases.

Thus, you will be satisfied with our high-quality service backed by years of expertise.

Our services include patent, trademark, and other IP matters.
