About Us

Our Story

Allegro IP was established separating from a long established Japanese intellectual property law firm, Yanagida & Associates, which was founded in 1973.  All of the members were former colleagues of the foreign clients team at the Yanagida firm, and our team were selected from competent attorneys who are capable of providing the best services to overseas clients. 

The reason why we finally decided to establish a new firm was to eliminate the negative effects of Japanese large/old-line IP firms.  Firstly, generally speaking, as the IP firm grows, they tend to place emphasis on large companies’ cases.  However, we would like to support the most advanced companies, which sometimes are small venture/start-up companies, in obtaining IP protection in Japan with the understanding of the inventions based on the cutting-edge fundamental research.  We make active use of official fee reduction program for such companies.

Secondly, the service fees tend to go up drastically as the IP firm grows, but we would like to keep the costs to be charged to our clients to a minimum.  This is sometimes because, at a large firm, the actual handling attorney is an associate and a partner supervises him/her and charge both attorneys’ fees. 

At our firm, there are no paralegals or associate attorneys, and the same partner attorney is responsible for handling each case entirely from the filing (even including translation) through prosecution.

Thirdly, the Japanese IP firms usually place emphasis on domestic (Japanese) clients’ cases, and when the clients wish to file foreign applications, they tend to work with foreign associates in a reciprocal manner.  However, we exclusively focus on IPR including patent and trademark matters in Japan for overseas clients and we make it a rule to not work with foreign associates in a reciprocal manner.

Therefore, we pride ourselves in Allegro combining the merits of new and old-line firms, and are confident that we can provide our best services to clients in a timely, high-quality, and cost effective manner.
