I will not worry about EDIG being a Patent Troll. if I were you...
Those who have Billions in the piggy banks, i.e. Samsung, Sony, Apple, TI, INTEL, etc. would and have spent some of that money in the past to cover up their tracks in having infringed on the patents of others...
During the last Administration they spent a lot of money in creating the term Patent Troll, and to they tried to have legislation passed to curtial the so called "Patent Troll" activity. It did not happen then, and it won't happen now.
Edig has been around since Day One of the FLASH Era. They were one of the original five companies who brain stormed the very idea of using FLASH. They are no stinkin FALSH TROLL...
