DEFINITION

Classification: 455/269

With wave collector (e.g., antenna):

(under subclass 130) Subject matter wherein the receiver includes wave collecting or antenna means combined with the whole or a specific part of a receiver system and wherein the claimed combination does not form a subcombination of a more comprehensive otherwise classifiable systems.

(1) Note. For purposes of classification in this class the word collector is generic to antenna and includes, in addition to antennas, such devices as inductive pickup coils and other devices intended to supply radio frequency or carrier wave energy to the input of a receiver. In this and the indented subclasses the collector system will include the antenna or coil along with the connecting circuitry up to the input terminals of a preselector, radio frequency amplifier or mixer means which forms the first stage of a receiver.

(2) Note. An antenna or collector means as defined in this class will include a physical device in the form of a metallic current conductor, waveguide, or space discharge device in direct engagement with free space and whereby an electromagnetic energy wave or a wave travelling in restricted space.

(3) Note. Nominal recitation of antenna, or of "antenna circuit" plus specifics of an indent below is sufficient to classify herein.

(4) Note. The combination of significant antenna structure and significant radio structure is classified herein. However, where detailed antenna structure is combined with nominally recited radio structure, classification is in Class 343, subclasses 700+. For example, such terms as transmitter, receiver, and signal source are considered nominal recitations of radio structure.
