The next big case to pay attention to concerning software patents appears to be the CLS Bank v. Alice Corp. case, which is being reheard "en banc" (by the full slate of judges) at the federal circuit court of appeals (CAFC). The short version of the case is that it involves a patent over the idea of software that conducts a "shadow transaction" to make sure that there are enough funds to complete a real transaction, before allowing the real transaction to go through, thus minimizing "settlement risk" (the risk of the deal not actually being completed). Should that be patentable? Well, that's part of the argument. The district court tossed out the patent as being simply about an "abstract idea," which is not patentable, as abstract ideas are excluded from section 101 of the patent act, which lists out patentable subject matter. On appeal, a divided three judge panel overturned the lower court, and said that when you looked at the invention as a whole, it was patentable subject matter under section 101. The full CAFC has agreed to rehear the case, and the amicus briefs are flowing in, as people realize that this case is the next key battleground over software patents.
