Chessbase sued by Stockfish

After infringements of its open-source license, the Stockfish team hired the Berlin law firm JBB to reach a recall of Fat Fritz 2 and termination of Houdini 6 sales. Even though Stockfish withdrew the General Public License from Chessbase, the German software house keeps selling Stockfish-based products. Stockfish has now announced a lawsuit against Chessbase in a German court.
