R&G did their DD at the USPO before taking SFOR on as a client. That DD was far more than IP legalities. It was technical. How do I know? I read the resumes of many of the lawyers assigned to SFOR cases. What leapt out at me is what they got their undergrad & in some cased grad degrees in before law school. Things like EE & IT were seen. These people knew they would have a winning case load! Once this first group of infringers is vanquished in court the word will get out. You have to pay to play so you may as well belly up to the bar & pay the tab or you'll be taken to the cleaners (treble damages) by R&G. In time it will turn into a wash, rinse, repeat thing for R&G until it becomes a knock & drop. That's when once a court summons is delivered infringing company counsel simply sighs & advises the BOD to pay the piper with no contest.
