> But licensing or suing isn't leveraging their current monopoly

Using the income from monopoly A for threatening to drag players in market B (that's about to become more relevant than monopoly A) into legal wars that only the plaintiff can afford is... well... shady.

> They're suing over patents. Last I checked even monopolies could sue over patent infringement.

Unless they are using those patents to prevent competitors from competing with them. If you consider the mobile ecosystem as competition to the desktop ecosystem, you can argue they are leveraging a monopoly (because the monopolist in segment A can afford a legal battle nobody in segment B can) to prevent it from being rendered worthless by a segment they can't monopolize.
