Even if the patents are accepted, you will still have to defend it in court because other patents could have been filed earlier which have significant overlap of your patented idea which could invalidate everything. I have personally seen engineers getting patents granted for technology which is obviously already in use elsewhere and is already patented. USPTO is a joke especially for software based inventions. I just want to know, how can anyone even claim to know they aren't infringing on some part of one of the nearly 300,000 patents granted yearly?
