We assume they came about because of a settlement: IMHO in the recent cases eDigital vs ArcSolft and eDigital vs IBaby both were Setteled at Mediation per "Pacers". The details of each "Settelment" are not disclosed thereby leaving one to assume the Settelment content. Looking at past Press Releases it was mentioned that there is a reluctance to negotiate without at least a threat of infringment litigation. Assuming a positive outcome isn't a bad thing based on what limited information is available to arrive at a "Best Guess".
