SHIRASAKA International Patent Office was founded on April 1, 2011. Our mission is “to spread innovation from Japan to the world.” The office was incorporated with SHIRASAKA & PATENTPARTNERS on December 1, 2017. We have since been providing a full range of intellectual property legal services in Japan and abroad.
From January 2019, we renewed our logo with the motif of “1 (Hajime)” derived from the name of our founder, SHIRASAKA.
We will continue to do our best without losing sight of our initial goals.
