Stockfish vs. ChessBase for GPLv3 violation: court hearing soon
It's going to be interesting because it's in Germany, which is in Europe. There's been a recent court case in France that ruled that copyright claims based on the GPL were invalid because it is a contract, and you can't claim both copyright and a contract on something, so it should be dealt with in civil contract court. (Or in other words, granting a license like the GPL invalidates all copyright claims you might have in the future!)The article is quite light on details, I wonder on what exact grounds they filed their claim.
