Gnome got Rothschild to agree to never sue another open-source project again. That's a huge concession and an outcome that's arguably better than a few invalidated patents.
I guess that depends how much of the Rothschild portfolio is applicable against open source software. A few invalidated patents, plus a strong message that trying to put a FOSS project through the ringer will get your patent invalidated could be far more powerful than just one promise from one entity.
Also, there's a question of how widely this legally binding promise is... will it apply to anyone else who wants to buy these patents?
