Source: USPTO903.06 Harmonized Subclasses [R-07.2015]
The U.S. Patent Classification System (USPC) includes subclasses that have been harmonized with subclasses from the European Patent Office (EPO) and the Japan Patent Office (JPO). Subclasses that have been harmonized have a designation of “EPO,” “JPO,” or “EPO/JPO” in parentheses following the subclass title to indicate if the subclass has been harmonized with the EPO or JPO or with both systems.
