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 hav…

I think the case you're thinking of was in France:

I'm happy that after years of nonchalant abuse of GPL by ChessBase, Stockfish authors have finally taken the matter to the courts. I wish the damages claimed were more.

Lets just hope they actually win (and judges actually understand the matter or people, who do advise), otherwise this is a disaster.

It’s not a disaster, because in Germany there is Roman law, as opposed to America’s common law. It’s different and it makes a sentence something much less disastrous.

So both cases are in Europe?

That makes no sense to me. Licensing copyrighted work is pretty standard, and it must be in France too? The GPL is a license, which is indeed a contract. But surely people license (enter into a contract between copyright holder and user which grants certain allowed uses) copyrighted work in France routinely?

German courts don't have the best reputation when it comes to technical subject matter.

how about the case of Christoph Hellwig vs VMware for stealing vmklinux under the GPL. german courts basically dismissed him twice for not being procedural, which gave VMWare ample time to dodge a GPL bullet and remove the code from their kernel without admitting any fault or wrongdoing.

That was a design patent not a case of technical implementation.

In the United States, a design patent is a form of legal protection granted to the ornamental design of a functional item. Design patents are a type of industrial design right. Ornamental designs of jewelry, furniture, beverage containers (Fig. 1) and computer icons are examples of objects that are covered by design patents.

[...]

A US design patent covers the ornamental design for an object having practical utility. An object with a design that is substantially similar to the design claimed in a design patent cannot be made, used, copied or imported into the United States without the permission of the patent holder. The copy does not have to be exact for the patent to be infringed. It only has to be substantially similar.

American courts are an extremely low bar for comparison.

This is complete nonsense without any data to back it up.

I think the distinction is that if the parties involved don't have a contract between them, copyright law applies.

But if there is a contract in place, then copyright law no longer applies, and you instead have to resolve any disputes as if they were violations of a contract.

The difficulty being that the GPL allows anyone to enter into a contract without even consent of the other party, and the contract law courts may not see that as a valid contract.

No, it doesn't. Voluntarily, publicly offering the GPL as license terms is consenting to others accepting that offer.
