As gjm11 noted, the font software is copyrighted (as I understand it), the actual glyph design is what can't be copyrighted. If you are still distributing a portion of the copyrighted work (the font software), that would presumably be a copyright violation. I don't know the actual extent to which copyright protection covers font software or derivatives. There is at least some related case law, but I've only skimmed it and am not an attorney. That means you can not use the fonts for any electronic documents whatsoever unless you convert them to bitmaps, which means they are almost useless for PDFs. Font licenses always specifically address PDF embedding.
