I suppose, but this is the communications industry, where compatible standards are really necessary. Just think what it would be like if the PC industry didn't collaborate to make 802.11x! It's nice to be able to reach anyone in the country with a 10 digit number, and I think soon enough, 2-way will be the same way. For one example, Nextel phones are very popular with emergency response groups. I know that during storm restoration, that 2-way feature pays for itself many times.
Not sure why polariod gets to keep their patent. Maybe because it's old technology and is grandfathered in. Maybe it's because it's not communications based. It's not like it matters much anymore, what with digital cameras an all.
Give what you cannot keep to gain what you cannot lose.
