It's not hard to come up with a ball park figure. Look into the patents and do some research. Also look at the history of similar past cases. We aren't going to spell it out for everyone. Go UOIP
Just look at Apple in 2015 paying $532 Million to Smartflash for infringing on their patents. The company was only valued at 4.5 million. That case was weak but they still won just like UOIP will!
