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.
