Thanks. Yes, I shouldn't have asked about "verbatim" copies -- I should have asked about something more like "close enough to cause legal trouble". Obviously copying verbatim is a violation of copyright, but there must be some threshold of "close enough" that is still problematic. E.g. compressed MP3s of copyrighted songs aren't a verbatim reproduction, but as far as I'm aware they're still covered by copyright. Trademarks are even broader.
