Good Faith and Reliability

On September 4, 2025, Aoyama & Partners celebrated its 60th anniversary. In human terms, especially in Japan, this is a milestone year - the year of the 60th birthday. Aoyama & Partners has reached a major turning point for further development.

More than 60 years ago, in 1965, Aoyama & Partners was founded. As a patent firm with strengths in the pharmaceutical field from its early days, we have handled a wide range of international matters and have been involved in many litigations both inside and outside Japan. As a comprehensive patent firm with patent attorneys specializing in everything from life sciences, chemistry and materials science, electricity, electronics, IT, mechanical engineering, to designs and trademarks, we are able to meet a wide range of needs. In 2001, Aoyama & Partners established an office in Tokyo in addition to Osaka. Furthermore, the firm has gained a high level of client trust by thoroughly managing deadlines using a newly developed system in cooperation with a software development company.

Meanwhile, the environment surrounding patent firms is changing dramatically. Intellectual property has become a powerful strategic tool for doing business and has come to play a very significant role. In addition, as symbolized by the spread of the internet, the volume of information disseminated on intellectual property has exploded, and at the same time, anyone can access the latest information. In addition, there has been a fusion of technologies from different fields, such as IT in medicine and biotechnological elements in electrical machinery.

In the face of these major changes, Aoyama & Partners is also entering a new phase. We aim to be a firm that systematically pursues a vast amount of up-to-date information that individuals cannot keep up with, and that goes beyond simply collecting information; rather, we aim to analyze and utilize it to propose application strategies, litigation strategies and other strategies to our clients. Dealing with the fusion of technologies from different fields is one of the specialties of Aoyama & Partners, as we have patent attorneys with various technical backgrounds. In addition, a new legal department was established in April 2017 to focus specifically on litigation matters.

Times have changed dramatically and so have the demands of our clients. However, one thing has remained unchanged since the firm’s founding and will remain unchanged in the future. It is to meet our clients’ needs in a professional manner, and to challenge and resolve all issues related to intellectual property. Each and every one of our employees aims to consistently satisfy our clients by striving to provide the highest level of service that exceeds our clients’ expectations.
