On June 12, Tesla CEO Elon Musk posted this on Tesla Motors' blog:
“Yesterday, there was a wall of Tesla patents in the lobby of our Palo Alto headquarters. That is no longer the case. They have been removed, in the spirit of the open source movement, for the advancement of electric vehicle technology.”
For those who've not seen the wall of Tesla patents that no longer exists, here are a few images (non-licensed, no copyright restrictions and free to use forever, of course) from Steve Jurvetson, Tesla Motors board member and the world's first Tesla Model S owner.
