But in that sense copyright is in the same league as any other itellectual property right (like artistic rights, trade mark rights, etc). Note that in the case you describe it is the patent holder that has to sue you, not the other way round. And a proveable copyright (which requires publication, otherwise you can't have a copyright!) would be a very easy proof of prior art, so I doubt the patent holder would gain much by sueing the copyright holder.
