Over two years ago, Tesla open-sourced all its patents for electric vehicles – a surprising announcement in our IP-centric business climate. CEO Elon Musk explained the move as being in line with Tesla’s mission to accelerate the advent of sustainable transport:

“If we’re all in a ship together and the ship has some holes in it, and we’re sort of bailing water out of it, and we have a great design for a bucket, then even if we’re bailing out way better than everyone else, we should probably still share the bucket design.”

We might get access to yet another bucket design thanks to Proterra, a leading manufacturer of all-electric buses. The bus maker announced today that it will be opening its proprietary “on-route fast-charging technology” on a royalty-free basis.
