ATAGO IP

greeting

On August 1st, 1979, the late Unosuke Aono and the late Hisazumi Ono, started up as a firm which dealt with patent matters specializing in the mechanical engineering field and trademarks. On August 1st, 2002, the firm merged with the patent office of the late Ikuo Suzuki, which was founded in 1971 and mainly handled patent matters in the chemical field.

Since the start of our practice, we have striven to strengthen our knowledge in intellectual property laws and technical fields in order to meet our clients' requests precisely and promptly.

We will continue to respond to the advancement and increasing specialization of technology and to the ongoing internationalization of industry. All of our staff will make their best efforts to help our clients execute their intellectual property strategy.
