Patent lawsuits are a joke. Been through 3 of them, two losses and waiting for the third to die a brutal death. It doesn't matter what does matter is to get to market when the window of opportunity is wide open and not 3/4 shut. You can come in late and be the big winner if your marketing and sales people can show value. I do like hat ZTlido has its own web site. Progress. https://www.ztlido.com/
