recoiledsnake writes "Groklaw has an extensive look at the latest developments in the Psystar vs. Apple story. There's a nice picture illustrating the accusation by Apple that Psystar makes three unauthorized copies of OS X. The most interesting, however, is the last copy. From Apple's brief: 'Finally, every time Psystar turns on any of the Psystar computers running Mac OS X, which it does before shipping each computer, Psystar necessarily makes a separate modified copy of Mac OS X in Random Access Memory, or RAM. This is the third unlawful copy.' Psystar's response: 'Copying a computer program into RAM as a result of installing and running that program is precisely the copying that Section 117 provides does not constitute copyright infringement for an owner of a computer program. As the Ninth Circuit explained, permitting copies like this was Section 117's purpose.' Is Apple seriously arguing that installing a third party program and booting OS X results in copyright infringement due to making a derivative work and an unauthorized copy?"
