Bilski: What It Means, Part 1 (Groklaw)
Groklaw analyzes the Bilski decision with an eye toward its effects on free software. "
As you no doubt recall, Red Hat argued in its amicus brief that abstract ideas are not patentable. That argument won out. But Red Hat also argued that abstract ideas are not patentable *just because there is a computer involved*. The court didn't go that far. In a way, it found the opposite, that a machine has to be involved. But what it said was that as far as software is concerned, future cases will have to decide exactly where the line is."
