This is kind of unprecedented, but Tesla might just open up its electric car patents to other manufacturers. On June 3, at Tesla’s annual shareholder meeting at the Computer History Museum in Mountain View, California, Elon Musk, the company’s CEO, said that to drive the adoption of electric cars, Tesla was “playing with doing something fairly significant on this front which would be kind of controversial with respect to Tesla’s patents.” Three days later, he told the BBC’s Theo Leggett that he was on the right track when asked if he was planning to give technology away.
