Sounds like a nice way for lawyers to get rich and spawn more lawyers - not only on future work but I would presume prior work is up for grabs too.

"Essentially, this Bilski decision invalidates most business method patents that don't specify innovations in machinery or physical processes..."
i dont know if i've understood this properly but does this mean that all software patents are now invalid? or does this mean that all the coding that hasn't found any application in a machinery yet is patent free? can someone explain this?

We're one step closer to seeing the end of software patents and in turn putting patent trolls on ice...`

What's going to happen to the economy when you can't patent one click shopping? Bye bye innovation.
