A Locarno International Classification designation consists of two pairs of numbers separated by a hyphen. The first pair of numbers designates a design class; the second pair of numbers indicates a particular subclass within the design class. The Locarno Classification manual, available from WIPO, delineates the individual classes and subclasses and includes: (1) a general list of classes of industrial designs divided into broad subclasses; and (2) an alphabetical list of specific industrial designs with an indication of the classes and subclasses into which they should be classified.
