Their license strategy is pretty different from Apple though. They go to OEMs and shake them down for a small licensing deal clouded in other deals and agreements, and also promises to make or keep making Windows Phones etc. Their goal is never court cases except in cases like BN (which they quickly settled later). The strategy is to build up precedents and take small amounts instead of full blown lawsuits requesting $30/device. Looks like the deals are okay with the OEMs, that's why there haven't been high profile lawsuits except with B&N.
