Our History


The world was a very different place when Asamura Patent Office was founded in 1891. When Mr Saburo Asamura opened his office, telephones were only beginning to become widely commercially available. In the century that followed, the company has seen the technology transform the way people live their lives. Intellectual property has played a central role in fostering this innovation, helping great companies stand out from the competition and benefit from their creativity. Today, we are always looking to develop and get better. But everything we do is rooted in our rich history and experience of working with companies from all over the world.
