"The usual expectation among companies has been that standard essential patents will be inexpensively licensed to anyone."

Last sentence is interesting. Hope this implies that these are inexpensive because of a shared tit-for-tat relationship. I'll give you a deal on my stuff if you give me a deal on your stuff. In the case of PTSC, there is not a tit-for-tat relationship. Do not use their patents since there is not any product from PTSC. No reason to give anything away on the cheap. thanks for the information.
