With both Microsoft and Apple filing complaints, it's likely the European Commission will launch a full blown investigation into Motorola's actions.
Since I follow MMI's aggressive litigation and enforcement activities in Germany closely (I watch all of the related court hearings), I can see what Apple and Microsoft are complaining about. If every owner of standard-essential patents behaved like Motorola, this industry would be in chaos, and grind to a halt. Just in the field of wireless telecommunications standards, there are hundreds of essential portfolios, and Motorola's assertions also include related technologies such as the H.264 video codec.
Apple has repeatedly asserted that Motorola is making outrageous demands for use of its FRAND patents. Recently it was reported that the company demanded 2.25% of Apple sales.
