Lodsys will probably ask for an injunction of some sort, restricting further sales of the alleged infringing products. Take-Two and Electronic Arts, which are large publicly traded companies, are fellow defendants. The defendants have 3 options: 1) discredit the IP claim Lodsys is making on the technology 2) prove they are not infringing 3) pay the fees Lodsys is asking. I would suspect Rovio to follow the lead of the larger co-defendants in this case.
