The fair use doctrine further restricts copyright's protective scope based upon numerous factors.85 A key factor is the nature of the work. Copying is substantially restricted as to works of fiction compared to a relatively more expansive fair use zone as to works of fact. Standards reside on the fact end of this continuum. When embodied in law, standards move to the extreme end of the continuum as facts (indeed, standards embodied in law may be the ultimate facts in copyright terms).
