IMO : TIER 1 LICENSES & Long litigations process similar to Ericsson in 2G. While filing complaint in ITC is a good things to do however it shows licensing with TIER 1 is not well progress. It will take time before any revenue plus increase litigation expenses. Some with short term perspective want to exit out.
The possiblity of large gains is tempered by the chance of big losses, you have to take the BITTER with the SWEET. YOUR PLAYING WITH THE BIG BOYS. Investing in IDCC is not investing in your everyday muny fund. PUNKIN611
