It's wild to me that there haven't been more court cases to answer questions like those being asked in this thread.

No one knows.

It's new, fast-moving technology, and the courts are slow and expensive.

It would take two stubborn businesses with a lot of money deciding that it is better to battle it out than focus on their business. Something like IBM v SCO or Oracle v Google.
