Please correct me if I am wrong since I am not sure if I got all facts right.

Motorola is currently holding a patent on push technology. One of our courts in Germany stopped iCloud from pushing due to patent infringements. Now that Google bought Motorola Mobility do they own they patent?

If this would be the fact I would predict that we will see more lawsuits against Apple regarding this one patent. Sounds like a great weapon - forcing your competitor to kill one of the interesting parts of a service they use for advertisement.
