Today was a pretty big day in the electric vehicle world, as Tesla CEO Elon Musk wrote in a company blog post that the California based company would not initiate patent lawsuits against anyone who, in good faith, wanted to use their technology.

While the term “good faith” is a subjective one, Musk’s announcement opens up Telsa’s arsenal of patents to any other OEM, with the hope that the adoption rate of electric vehicles at these manufacturers will be improved.

Making Telsa’s patents “open source” effectively creates a minimum standard of technology in electric vehicles, and the move now means that OEMs should only use their own EV technology if it performs better than Tesla’s.

That’s a pretty big win for consumers, since Tesla’s technology is generally highly regarded. It also means that the jumping-in point for OEMs into electric vehicles is substantially lower.

If a small manufacturer, or small product team in a large OEM, wants to start an EV project now, they can use Telsa’s patented technology to jump-start their development, and bring something to market quicker.
