Bilski's growing up, and smacking down some bad software patents:
"That trend is continuing in a good direction. A new study of the first full year of decisions applying Bilski to software confirms that the direction of the case law is toward finding software is not patentable subject matter. The study by Robert Greene Sterne and Michelle K. Holoubek is titled The Practical Side of §101 : One year post-Bilski: How the decision is being interpreted by the BPAI, District Courts, and Federal Circuit. [PDF] It contains brief summaries of 182 decisions of the BPAI, 6 federal district court decisions, and 3 Federal Circuit decisions. The majority of the BPAI and district court decisions concern software. And many of those software decisions apply Bilski to find that the subject matter is too abstract to be patented."
