Kita-Aoyama International Patent Bureau (KIPB) is a specialist IP firm providing a complete range of personalized, client-oriented services related to the prosecution and enforcement of both domestic and international intellectual property rights.

KIPB has been partnering with RWS and working with the inovia platform 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 facilitates smoother prosecution.
