“Reining in”. It wasn’t easy to find a term that was both accurate and also vague enough to describe what just happened. The US Supreme Court today published its decision on Alice v. CLS Bank. It’s too early to say exactly what the effects will be, but the news is certainly all good: The Court in no way extended patentability nor did it affirm patentability for any sub-category of software; and a certain category of software patents has definitely been invalidated.
