You don't understand Lessig's argument. The problem is retroactively extending copyright -- that is where they made the mistake. They ruled that it was up to congress to decide how long copyright was and as long as it was for a limited time it was ok -- this is the correct judgement. Hopefully they'll have a similar ruling -- if we want patents to apply to business methods and software we will have to explicitly pass a law to allow it.
