A good, unanimous, decision. EFF:
In a long-awaited decision, the Supreme Court issued its opinion in Alice Corp. v. CLS Bank today, striking down an abstract software patent. Essentially, the Court ruled that adding “on a computer” to an abstract idea does not make it patentable. Many thousands of software patents—particularly the vague and overbroad patents so beloved by patent trolls—should be struck down under this standard. Because the opinion leaves many details to be worked out (such as the scope of an “abstract idea”), it might be a few years until we understand its full impact.
