The plot thickens yet again in the seemingly endless patent war between Apple and Samsung. A new ruling by a regional court in Dusseldorf, Germany has granted Cupertino a preliminary injunction, blocking the sale and advertising of the Galaxy Tab 10.1 across Europe, save for the Netherlands. Samsung can still appeal the ruling -- in the meanwhile, however, the decision will stand. According to The Telegraph, the likely appeal will take about a month to be heard by the judge who granted the injunction.
