Kita-Aoyama International Patent Bureau (KIPB) is a specialist IP firm providing a complete range of personalized, client orientated services related to the prosecution and enforcement of both domestic and international Intellectual Property rights.  KIPB has been partnering with inovia/RWS since 2003 and has filed thousands of incoming patent applications with the JPO in that time with a high rate of success.

KIPB’s internationally experienced specialists fully appreciate how to articulate Japanese IP laws and practices for a global client base. The firm is equally adept at handling the IP needs of large multinational corporations as well as working with smaller start-ups and organizations in a clear and cost-effective manner. A specific policy at KIPB is to contact and discuss possible strategies and proposed amendments with examiners before official submission which encourages smother prosecution.
