Nokia must be desperate for cash. Developing video codecs is a painful exercise as some part of the implementation almost always relies on prior art. The company that I worked for were sued for our implementation of an MPEG-2 codec, because of a similar patent owned by a troll. These cases are what hold innovation back and are only attractive to the trolls because of how many h.264/h.265 codec instances are running out there. The usual technique is to go for the little guys first and then move up the food chain.
