Company History

Philip Parker established P. J. Parker & Co. in 2001 as an overseas corporation. From 2001 to 2005, we assisted high tech startups from overseas enter the Japan market.

In 2005, we established a Japan-registered company.

From 2006, we began patent brokering. Since then, we have steadily expanded our client base to include most of the top Japanese high-tech companies, as well as clients from Korea, China, Taiwan, the USA and Europe.

Our firm is now the largest patent broker in East Asia. We have sold and licensed more than 3,000 patents.
