Using most or all of a work does not bar a finding of fair use. It simply makes the third factor less favorable to the defendant. For instance, in Sony Corp. of America v. Universal City Studios, Inc. copying entire television programs for private viewing was upheld as fair use, at least when the copying is done for the purposes of time-shifting. In Kelly v. Arriba Soft Corporation, the Ninth Circuit held that copying an entire photo to use as a thumbnail in online search results did not even weigh against fair use, "if the secondary user only copies as much as is necessary for his or her intended use".
