Toyota Seeks U.S. Court Order Approving Use of Hybrid Technology

Toyota Motor Corp. sought a court order in the U.S. approving its use of technology in hybrid electric vehicles, including the Prius and Lexus RX 400h, after an auto-parts company claimed its patents were infringed. Efficient Drivetrains Inc., based in Palo Alto, California, has an exclusive license from the University of California for use of the technology, including the way electricity is drawn from a battery to power an electric motor and an internal combustion engine, according to a July 20 federal court complaint filed by Toyota in San Jose, California.

“EDI has contended that the Toyota Hybrids infringe each of the asserted patents and has indicated it intends to enforce” them, according to the complaint filed by the Toyota City, Japan-based automaker. “Toyota denies that.”
