The big news from Tesla this week is that the company said it plans to share its patented technology with the world.
CEO Elon Musk made the announcement on Thursday, June 12, 2014, on the Tesla blog, writing that he was making the move “in the spirit of the open source movement” for the sake of “the advancement of electric vehicle technology.”
Musk’s blog post was humorously titled “All Our Patent Are Belong To You,” a take-off on the popular “All your base are belong to us” meme.
“Our true competition,” Musk wrote, “is not the small trickle of non-Tesla electric cars being produced, but rather the enormous flood of gasoline cars pouring out of the world’s factories every day.
