SECTION I - CLASS DEFINITION
CROSS-REFERENCE ART COLLECTIONS
This class includes arrangement or mounting of plural prime
movers for mutual or common propulsion of a vehicle. This class
includes specific HEV topologies, components, and arrangements of
components specially adapted for HEVs, as well as controls of components specially
adapted for HEVs.
This class was initially established as a result of a joint reclassification
project of HEV technology completed by the Japanese Patent Office
(JPO) and the European Patent Office (EPO). At the time of introduction,
all U.S. documents in these subclasses were either classified directly
by the EPO or JPO, or through family member processing of classified
documents. The subclasses also contain foreign documents classified directly
by these countries.
Since Class 903 was established, many of the related IPC subclasses
were abolished. Additionally, some of the subclasses that had been
in Class 903 when it was established were transferred to Class 180
in January 2009. The U.S. patents are updated with classifications assigned
by U.S. examiners. Foreign patents for subclasses existing in the
IPC are updated on a regular basis from the EPO and JPO databases.
