The Mannheim Court in Germany has delayed Apple's second slide-to-unlock case against Samsung, says FOSS Patents. During this pause in proceedings, the German Patent and Trademark Office is examining the validity of Apple's slide-to-unlock utility model.

A utility model is a quickly-approved patent that's not presumed by the court to be valid because it hasn't been fully examined by the patent office. Now that Apple is asserting it in a lawsuit, the patent office is taking a closer look at the patent and Apple's claims. This review process takes time and other appeals could delay a final ruling in this slide-to-unlock case.
