"IN previous posts about the re Bilski ruling [1, 2, 3], a cursory look at the ruling was all there was to be offered. Now that people have taken a more careful look, discussion among experts leads to better assessment and understanding of the decision’s impact on both business methods and software patents. Are they doomed altogether? Which ones? Would they hold water in court? Will they still be possible to obtain? What happens to existing such patents which applicants spent enormous amounts of time and money on? What does this mean to companies whose patent portfolio is their main or only business? These are all interesting questions and a subject that will be debated for quite some time."
