310 /   HD   ELECTRICAL GENERATOR OR MOTOR STRUCTURE



DEFINITION

Classification: 310/

This is the residual class for all subject matter, not elsewhere classified, relating to electrical generator or motor structure.

(1) Note. This Class was produced in 1953 by making official the unofficial digests which have been established by the Examiners of Division 26 during the period from about 1900 onwards. A caveat is given: while it is believed that the titles and definitions are reasonably accurate, no assurance can be given that all the patents, issued prior to the date of reclassification, are in the proper subclass since only some of these individual patents were read during the reclassification project. Consequently, in making a thorough search in this class, it is advisable to investigate every subclass which may possibly be pertinent and not, in order to shorten the search, to rely upon the principle of superiority of subject matter because of position in the schedule, since that principle is applicable only in classes where each patent has been analyzed and placed in the schedule in accordance with that portion of the disclosed subject matter which is claimed.

(2) Note. Since Class 310 takes, under the class definition, only subject matter relating to electrical generator or motor structure not elsewhere classified, its scope can be determined only by determining the scope of other related classes, which classes are listed below under search class. Also consult the search notes in the

definitions of these classes.

(3) Note. Many mechanical classes contain electrical disclosures, as where an electrical machine is disclosed in a mechanical environment, with which it cooperates. Consequently, in appropriate instances, the search must extend to the class or classes which relate to the environment in which the electrical disclosure may be found.
