Sam,
I believe the IBM-Microsoft collaboration lasted thru 1.1. Not sure about 1.2 or 1.3.
Version 2.0 and later were pure IBM, although any legacy code from the earlier versions
had a joint copyright. Gee, that copyright should have expired now - it been 20+ years...
I think you're maybe thinking of patents? US Copyrights take a lot longer to expire
(and, thanks to various high-stakes interest holders like those that Chuck mentioned,
probably never will at this rate).
