Car maker Toyota has announced that it will freely share almost 6,000 patents it owns covering hydrogen fuel cell technology.
It said it took the step in a bid to drive development of cars that use the alternative fuel source.
The announcement was made soon after it showed off its Mirai hydrogen-driven car in Las Vegas.
Toyota is one of a record number of car makers attending CES to unveil new models or connected-car strategies.
The patents will be made available free of charge to anyone wanting to use them. The patent portfolio covers fuel cell stacks, high-pressure hydrogen tanks, software control systems and the industrial processes involved in generating and supplying the gas.
“When good ideas are shared, great things can happen,” said Bob Carter, senior vice president of automotive operations at Toyota in a statement.
He added that the first generation of hydrogen fuel cell vehicles, which are expected to be launched over the next five years, would require “unconventional collaboration” among car makers, governments, power firms and researchers.
