Introduction

Allegro IP was established separating from a long established Japanese IP law firm, Yanagida & Associates, which was founded in 1973.  We were members 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 foreign clients.  Therefore, we believe that we are well experienced and that we are familiar with how to proceed with foreign clients’ cases in Japan.
Meanwhile, our firm launched in 2016.  As a new firm, we have thoroughly streamlined the firm’s system.  The firm’s operation is extremely sophisticated in all aspects, including security, administration, billing, etc., but at the same time, we have tried to reduce waste to keep the costs to be charged to our clients to a minimum.  Further, at our firm, only experienced partner attorneys handle cases before the Japan Patent Office, and there are no paralegals or associate attorneys.
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.
