If you have a useless paper, and you sell it to someone else, it's still a useless paper...

They are more of an inconvenience, and if they have deep pockets (like in this case), they can keep trying to fight legal battles, over and over for years. Making the other spend money in lawyers. Depending on the amount, it may be cheaper to just pay them and forget the whole thing, just like what happens in some patent cases with the hated patent trolls.

But when there's a huge sum at stake, sovereign states will fight in court. Until now, this fund has lost every case, but they keep appealing the verdicts. A few months ago, the US Supreme Court ended some of the demands, but they have opened a few more.

You get the idea... the kind of lawyers that make their profession look so bad.
