FCC Approval
A good acquaintance of mine is involved in a private venture with a device that also emits electromagnetic energy towards humans. It is a different frequency and a different application so don't worry as it is not in competition with Patscan. He said that his product only required FCC approval and it is already being marketed and sold to businesses. He said he is 99.99% sure that Patscan only requires the FCC approval too.
If you think Patscan needs FDA approval like your dad's Viagara then sell your PAT shares tomorrow morning at the opening bell and be free from all your worries.
