Not so fast, Ghors......IDCC has offered a FRANDly rate in regards to its SEP patents with 50% of the licensing base now signed and, afaik, ZTE offered a joke negotiable rate at almost zero and are involved in current arbitrations, too....You are much more informed than I am especially on IDCC....Not certain about VRNG, but they have issued statements that they are willing and able to offer FRAND rates.
However, VirnetX has signed contracts at officially published FRANDly rates @ 1% or higher and those rates have been been declared in their 10K as being fulfilled within those parameters. Apple is trying to kill the patient.
