Are we going to have this discussion again? Any advice given here, unless by an attorney who specializes in this area of law, is worth what what was paid for it. It seems to me there are four choices: (1) make whatever, sell them(which may be illegal, or not), and see what happens ,(2) pay for and get the advice of an attorney with knowledge in this area, (3) pay the licensing fee(s) and sell, sell, sell and sleep at night, or (4) leave it.
I'm not trying to be negative, but this topic will not be be answered here, or at least it hasn't been if I remember correctly. We have at least one member who is a patent attorney. And, I understand why attorneys or other professionals would be reluctant to give advice on a public forum. My intention is not to offend anyone but to just give my thoughts on this topic.
Do a good turn daily!
