If you are correct - and i don't doubt that you are - then this frustrates me even more around why corporations push to extend the life of their copyrights, trademarks, patents, etc. Patents and such were supposed to be an aid to kick things off (for a nascent economy), not survive for the long-ass life of some large conglomerate corporation to squeeze every little last drop of juice from all the existing citrus fruit! (Sorry, i guess lately i've been feeling very anti-corporation...and i haven't had my coffee yet today.)
