When Volvo created the three-point safety belt (still in use today), they patented their invention. And then, recognizing the importance of this great improvement in safety, they absolutely gave it away for free.

When SawStop created a meat-detecting brake for table saws, they patented their invention. And then, they refused to give it away, sued the begeezus out of anyone who tried to emulate their patented inventions, and eventually paid lip-service to the concept by offering to license one aspect of it for free.

Can you spot the difference?
