Introduction

Our Firm

President,
Patent Attorney.
Masahiro Yamaguchi

Founded in 1973 by former President Kazunori Kobayashi, our firm has filed and obtained numerous patents, utility models, designs, and trademarks in Japan and overseas.

As a professional in the acquisition of intellectual property rights, our firm will continue to acquire rights from the standpoint of the inventor, and will also focus on clarifying the distinction from conventional publicly known technology. We are trying to establish rights that are useful for competition and prevent disputes. In addition, considering the change of times and changes in Japan and overseas, we will consider what added value we can contribute to our customers and create an environment that allows us to be creative and ingenious.

Through the above-mentioned efforts, our firm will provide services of a certain quality and services that exceed the expectations of our customers.
