"ended the quarter with approximately 50 percent of all 3G handsets being delivered under license from InterDigital"
That's an implied improvement from the previous statement that IDCC had "~ 50% plus of 3G market under license at year-end 2010".
With that 2010 "approximate 50%" number being broken down by IDCC as 6% RIM (who have seen a large market share decline since then) and 8% LG (who have not renewed and have been added to the ITC complaint)...
...it makes one wonder if Apple + HTC have grown their share to the point it covers the 10+% implied difference (with RIM, LG). Or if something else is in the mix.
