Ono & Company was established in 1989 with the business mission of "contributing to society by providing high quality IP services, taking the viewpoint of our clients." Ever since then, we have devoted ourselves to providing comprehensive services to ensure optimum profits for our clients, the wide range of which not only includes obtaining and maintaining IP rights, but also searching for discoveries and aiding in the exercise and utilization of rights.
In addition, in 2007 we changed our formal status to "Patent Corporate Body" to help enable us to continuously provide more effective services over a long term.
