Save Time

Each member of our firm is always conscious of being highly responsive. We make positive use of expedited examination procedures, including PPH (Patent Prosecution Highway) and Super Accelerated Examination.

Save Money

We have tried to reduce waste to keep the costs to be charged to our clients to a minimum, not only our service fees but also the official fees. We often utilize the “Deduction of Official Fees” system even for overseas venture companies.

Direct Contact

We are familiar with how to proceed with overseas clients' cases in Japan, and we have been working directly with applicants to better understand cutting-edge inventions. We make it a rule to NOT work with foreign associates in a reciprocal manner.

Enjoy Security

The firm’s operation is extremely sophisticated in all aspects so that overseas clients may enjoy our best services in Japan without anxiety. You can get out of the trouble of managing Japanese patents with our quadruple check system.
