Interesting article, especially considering this; > **[The Hybrid Inventor Who Sued Toyota - And Won](https://www.wired.com/2010/07/alex-severinsky-toyota/)** > > Alex Severinsky is a Soviet engineer and immigrant to the United States who once developed antitank-warfare instrumentation. In 1994, he patented a system for powering gas-electric hybrid automobiles. Toyota has been using his system since 1997... I imagine this patent is expired now. Interesting it does not include Toyotas battery technology, a key element of a hybrid system.
