Active sticks have been in development for decades. They’re getting deployed on civilian crafts these days e.g. Gulf Stream’s top of the lines jets (though retrofitting them on existing planes is likely a ways away still).
I would assume the issues are / were around reliability, failure modes, certification and training rather than patents.
The force feedback is applied by the "feel computer". On the 757 it's a hydraulic device designed to apply forces to the control column simulating the forces on the control surfaces.
