from your former post:
Tesla took to the grave with him a $7.00 a horsepower royalty (about a penny a watt) for anything that produced or ran off alternating current. this he gave up to keep his system from being monopolized and to save George Westinghouse form a hostile takeover.
If he gave it up, how could he take it to his grave??
He had it, he gave it up to help Westinghouse, who was crying that the royalties were too much, that it would be the end of his business..
Westinghouse could have re-instated those royalties once the company was secured.. He didn't.. Never even offered..
Not necessarilly Westinghouse's fault, he was a businessman in the "robber baron" era, and did what he had to..
But the fact remains, Tesla gave up those rights..
