"Is there any way for us to determine if NDA does normally = some extreme?"

Opty we think the same. FWIW...I did run it by a patent attorney to get his take (see below), but of course it is just one man's opinion and of course he doesn't assign any $$ value. Good luck to you, me, us, and all longs.

"The NDA most likely weighs in our favor, but to guess as to how much would be purely speculative. The fact that big companies are settling in Texas and not trying to invalidate the patent is a good indication that the patents are worth something."
