USPTO and EPO Work on Joint Patent Classification System
The United States Patent and Trademark Office (USPTO) and the European Patent Office (EPO) have agreed to work toward the formation of a joint patent classification system. Unlike other major patent document classification systems, the U.S. patent classification system is not based on the International Patent Classification (IPC) system because it predates the IPC. One of the goals of the partnership is to align the U.S. and the EPO classification systems with the IPC, which is administered by the World Intellectual Property Organization (WIPO), a specialized agency of the United Nations. The jointly developed classification system will be more detailed than the IPC to improve patent searching. As a result, the two offices would move closer to eliminating the unnecessary duplication of work between the two offices, thus promoting more efficient examinations, while also enhancing patent examination quality.
