Hello Doug:
Actually I'm concerned about copyright which seems to go on just about forever. However, I guess we can assume for now that the general optical scan technology isn't patented. I would say that a full blown patent search should be put on the punch list prior to software release but not before.
Thanks, Ed Kennedy

I think the patents have expired. HP was using registration marks on
their mark-sense card readers in the early 1970's. I tried to do a
search for some of these patents and came up empty. Lindquist's name
doesn't seem to be on his patents -- he merely hired the guy who did
the actual inventing. Westinghouse Learning Corporation became the
licensee, and ES&S can actually trace its ancestry back to a failed
ballot tabulator developed at Westinghouse.
