USPTO and KIPO to begin CSP

A Collaboration Search Program (CSP) has been implemented between the USPTO and KIPO to enforce examination quality for patents filed in both countries. In May 2015, the U.S. Patent and Trademark Office (USPTO) and the Korean Intellectual Property Office (KIPO) signed a Memorandum of Cooperation (MOC) to begin a bilateral CSP. In fact, the two offices have formally begun the CSP as of September 1, 2015.


The CSP is designed to allow both offices to share their information of prior arts before the examination of the patent application takes place in order to improve prosecution process and patent quality. If an applicant, who has filed patent applications in both the US and Korea, requests for the CSP, the USPTO and KIPO will share each of their prior art in their search engines. From this, it may be possible to prevent the occurrence of a case in which a patent is registered in one country and not in the other.


The memorandum strengthens the ties between the USPTO and KIPO as their growing cooperative relationship has led to a positive outlook. It is expected that the new program will focus on expanding to other IP5s such as China, Japan and Europe to improve the international patent system.
