The Supreme Court has agreed to hear a case on how far software patents can go in covering an abstract idea. Today, the court said it would take on CLS Bank v. Alice Corp., a contentious decision over online trading tools. Next year, it will have to decide whether a handful of patents should be thrown out for cloaking a basic concept in technical terms — or whether doing so would effectively invalidate all software patents. Alice Corporation develops financial software tools, and it promotes its patent portfolio heavily.
