My understanding is that, while schematic diagrams are covered by copyright, the circuits they represent aren't. So if a schematic was drawn by you, you can distribute it without breaking the law. The fact that someone else holds a copyright on a different schematic representing the same circuit is irrelevant, provided that your schematic is not similar enough to be deemed a mere reproduction of it. Simply tracing the original on tracing paper would probably be considered a reproduction. Not that I'm a solicitor or anything like that. -- André Majorel http://www.teaser.fr/~amajorel/
