My question , and I don't know the answer is - can the company advertise '' our patented Laminar Flow Interrupter Technology '' after they let their patent go to public domain ?
I'm no patent / trademark attorney but did a little work with them on a portfolio of patents making decisions re paying the fees, abandoning and offering licensing.
My GUESS is they could advertise as they did invent and was awarded a patent for the technology.
They can't claim exclusivity, and certainly can't prohibit anyone else from using or even advertising use of Laminar Flow Interrupter Technology.
Note: that advice is worth exactly what you paid for it!
