The German company IPCom GmbH, which has been called Europe’s first “patent troll” by its opponents, lost three big infringement cases on Friday, including one in which it was seeking €1.6 billion ($2.2 billion) from Apple Inc. The law firms claiming victory include Freshfields Bruckhaus Deringer and Hogan Lovells.

A regional court in Mannheim, Germany, dismissed the $2.2 billion Apple case without providing its reasoning, according to FossPatents blogger Florian Mueller, who was in the courtroom. The same court also dismissed a related IPCom case against Apple, as well as a similar case against HTC Corp.
