After more than 60 briefs on both sides and an eight-month vigil for the ruling among patent lawyers, the decision in Bilski v. Kappos issued Monday may have done little to end the debate over what kinds of innovations are or are not eligible for patents. The long-awaited decision was supposed to resolve the patent eligibility of business methods or processes that are not tied to a new machine or don't transform anything. But while rejecting one such patent, it did not rule out method patents in general.
