Quoting a quote of the judgement here.

We should make clear that in the future companies like Lexmark cannot use the DMCA in conjunction with copyright law to create monopolies of manufactured goods for themselves just by tweaking the facts of this case: by, for example, creating a Toner Loading Program that is more complex and "creative" than the one here, or by cutting off other access to the Printer Engine Program.

The judges obviously understood exactly what Lexmark and other companies where trying to do and firmly putting a boot down. This judgement is so direct I hope the Supreme Court refuses any appeals.
