They don't need legal standing. They're a big company, and big companies sue people they don't like into bankruptcy. The basis of the claim only needs to look vaguely possibly meritorious for the lawsuit to be forced through the uber-expensive court circuit.

Only way to avoid being sued into bankruptcy after you've pissed off someone big enough is for your company to be doing dozens of millions each year at minimum, and thus, have the resources to tolerate the associated legal fees. If you make someone mad before this happens, expect to be forced to shut down.
