The latest installment of Apple vs. Samsung saga sees Cupertino taking offense with the lockscreen on the Galaxy Nexus. The complaint, filed once again in Germany, is the first directed towards the Android 4.0 flagship device. The claim made is that the Galaxy Nexus infringes upon Apple's own slide-to-unlock utility model.
FOSS Patent's blogger Florian Mueller describes this utility model as a limited fast-track patent that companies are allowed to file for alongside traditional patents. Apple has done just this with slide-to-unlock in Germany. Samsung's defense points to a device from Sweden known as the Neonode, which managed to persuade a court in the Netherlands in 2011 to question the validity of the Apple's slide-to-unlock filing.
The court is expected to reveal its decision on Mar. 16. What's clear already, though, is that we're sure to see more of these patent lawsuits as the year continues.
