They (TPL and PTSC) said that negotiations had started up again after the USPTO. Prior to that things had been on hold. Not necessarily meaning no agreements, but it seems that way to me. So these three more than likely came after the stall. I wondered if these 3 companies may be linked in some way that they all came about together. Or is it just a coincidence or a strategy? Now I wonder if the rate will continue at this rate of the three or increase. Bottom line more deals are signed and the share price is rising!!
