180, Motor Vehicles,
164, for a motor vehicle provided with means for creating a fluid force to attract the vehicle to the surface upon which it travels; subclasses 116+ for a motor vehicle of the surface effect type; subclasses 180+ for a ski- or skate- type vehicle for imparting movement to a person standing thereon; subclasses 182+ for a motor vehicle which includes one or more ski-like or runner members; and subclasses 7.1+ for a motor vehicle having a special driving device. Class 180 takes all wheel substitute vehicles, unless (1) a claim is drawn to a vehicle other than a motor vehicle, or (2) the claimed vehicle is identified as only a nonmotor vehicle in the specific disclosure, noting (1) and (2) do not apply to the special suction and surface effect vehicles. 305, Wheel Substitutes for Land Vehicles, for wheel substitutes, per se. Class 305 takes patents claiming the combination of a wheel substitute and a vehicle, if the vehicle is only nominally recited in the claims. Expressions such as a vehicle frame, an axle, a pivotal connection between the vehicle frame and the wheel substitute are considered mere nominal recitations of vehicle structure and would be classified in Class 305 if the claim is otherwise directed to a wheel substitute apparatus.
