DEFINITION

Classification: 343/766

(under subclass 763) Subject matter wherein the means imparting motion to the antenna is a motor.

(1) Note. The term motor as used above contemplates all devices other than manual for imparting motion to the antenna. The motor is usually electrical, but may be of another type such as fluid. To be classified herein the motor must be claimed as such, or as a means to rotate the antenna, or some similar recitation. Subject matter involving manual means to impart motion when combined with a rotatable antenna for scanning, sweeping or orienting is not classified herein but in subclass 763, above. As distinct from a motor drive, a manual drive is usually structure such as a handle, affording means to apply the manual force. In this latter case where the antenna is claimed by name only and involves, for example, a handle and mechanical motion

transmitting means, classification is in Class 74 and not herein.

(2) Note. For classification in this subclass the claimed combination of the motor and antennas must include detailed antenna structure as opposed to the mere recitation of the antenna or reflector by name only. In the latter case, classification is with the motor if the motor is claimed in detail. For example, subject matter involving a combination of an electric motor for rotating an antenna for scanning, sweeping or orienting, motor control, and antenna, where the antenna is claimed by name only, is not classified herein.
