If that is the case and the german court ruling is not responsible for either Roper or Unisys signing then we can narrow down the potential impetus for these companies to sign at this time. They recognize a gross error on the part of the conclusions reached by the PTO examiner. They agree that they infringe other MMP patents. O r maybe because TPL was trying to save some face after 336 rejection, they were offered the sweetest of sweetheart deals. If other signings pop up in the short term....my inclination would be to assume they were just offered a big discount. Hopefully, the reasons are because of positive developments that we are not privy to. good luck
