I'm curious if the Hush-A-Phone case is any precedent: https://en.wikipedia.org/wiki/Hush-A-Phone_Corp._v._United_States https://en.wikipedia.org/wiki/Hush-A-Phone_Corp._v._United_S... . It involved a company that made a device you connected to your telephone who got sued by AT&T and won. The compatibility with a proprietary phone network is vaguely analogous to an API.
