[TowerTalk] Tower Jack?

[Larry]

Patents are renewable if I recall. I don't know if they changed when they 
changed trademarks. Trademarks are good as long as the owner is still alive 
and other rules (used to be 28 years and renewable once). I have lost touch 
with the IP law stuff.

73, Larry  W6NWS

Patents are only good for 18 years.  Surely this thing is out by now.
