no, obviously they went to the trouble for the licensing fees. but they did, as a side effect to the licensing fees, agree to make their invention freely-practicable -- as opposed to the default, where it would be protected by trade secret laws in perpetuity -- after their monopoly period ended. so that's worth something, I guess.
