Patent trolling
Extracted from the Wikipedia article Patent troll.
Patent trolling has been less of a problem in Europe than in the United States because Europe has a "loser pays costs" regime. In contrast, the US generally employs the American rule, under which each party is responsible for paying its own attorney's fees. However, after the US Supreme Court's decision in Octane Fitness, LLC v. ICON Health & Fitness, Inc. on April 29, 2014, it is now easier for courts to award costs for frivolous patent lawsuits.
