A New Kind
Of Agency.
Greeting
We acquire patent rights with accurate understanding, logical thinking and communication skills. Boost your business to infinity !
Katsunuma International Patent Office is a patent office that opened in January 2017.
Although the office is new, I has been involved in patent work for nearly 30 years.
My belief of doing my best for the clients has never changed all the way.
After working in a large firm as its president, I opened my own firm as I believe a patent firm should meet the demand of the times.
The service of a pant firm of today must be quick, flexible and attentive.
The fruits of intellectual properties depends on the spirit and capability of the patent attorneys you choose.
Please try us! I am looking forward to the exciting encounter with you,
hoping I can do something for you.
Please feel free to contact us.
Sincerely yours,
Hirohito KATSUNUMA
