Nokia (NOK 6.11%) is notably hanging on to its wide patent portfolio instead of selling it to Microsoft (MSFT 0.46%), opting to license its IP to the software giant instead. To date, the company has primarily used its patents defensively.

Nokia's IP is a valuable asset that it can continue to monetize, and the company could potentially pursue Google (GOOGL 1.42%) Android OEMs aggressively for royalties. If so, that would add yet another layer of costs for Android vendors looking to bring devices to market.

Even within Nokia's existing cross-licensing agreements, the company can effectively eliminate its outgoing royalty payments since it will no longer sell handsets, and keep the incoming royalty checks flowing in.
