This is getting a little far from Apple perhaps but it's fun to cite these cases of big companies throwing their weight around.
AT&T also tried to prevent the distribution by other companies of free covers for their phone books. They owned the phone book they'd given you. You did not have the right to put someone else's cover on it to protect it.
AT&T also tried to prevent a rancher from making an audio connection (phone speaker put next to radio microphone etc) from his phone to a radio so the rancher could make calls while driving around his ranch. That's the Carterfone case.
Marconi licensed, not sold, his radios to ships like the Titanic. The license prohibited communicating with non-Marconi radios. That lasted until WW1, when the US Navy said, stop that.
GE licensed the vacuum tubes in car battery chargers. The customer was prohibited from using the tube in a radio.
