This is the generic class for electrical apparatus and corresponding methods for performing calculation operations.
SCOPE OF THE CLASS
(1) Note. This class is limited to electrical and calculating computer apparatus and corresponding methods wherein a calculation operation is performed on information carried by wave propagation (either electromagnetic or compressional waves) provided that input to and output from the apparatus is electrical. Note: where the apparatus performing the calculation operation is electrically responsive but the data is not presented to and output from the apparatus as electrical signals, classification is with the appropriate wave energy subject matter, as per one of the optical classes.
(2) Note. Significantly claimed apparatus external to this class, claimed in combination with apparatus under the class definition, which perform data processing or calculation operations are classified in the class appropriate to the external device unless specifically excluded therefrom.
(3) Note. Nominally claimed apparatus external to this class in combination with apparatus under the class definition is classified in this class unless provided for in the appropriate external class.
THIS CLASS IS STRUCTURED INTO THREE MAIN DIVISIONS:
A. Electrical Hybrid Calculating Computers
B. Electrical Digital Calculating Computers C. Electrical Analog Calculating Computers
