https://techcrunch.com/2019/04/03/toyota-is-giving-automakers-free-access-to-nearly-24000-hybrid-car-related-patents/ > Toyota said Wednesday it will give royalty-free access to its nearly 24,000 patents related to electrification technology and systems through 2030 in a move that aims to encourage rival automakers to adopt the low-emissions and fuel-saving technology. > Collectively the patents represent core technologies that can be applied to the development of various types of electrified vehicles, including hybrid electric, plug-in hybrid electric vehicles and fuel cell electric vehicles, Toyota said. This follows Toyota’s decision back in 2015 to offer 5,680 patents related to its fuel cell electric vehicles.
