Gene Quinn says otherwise
Here is what Gene has to say about Bilski. Gene is a US patent attorney, professor, and president of IPwatchdog. He also wrote software and patented them himself and is a big advocate for software patent. From time to time I disagreed with him but on this one I had to admit he is right.
On October 30, 2008, the United States Court of Appeals for the Federal Circuit issued its decision in In re Bilski, which dealt a serious blow to software patents and largely did away with business method patents altogether, although there is still some room to receive a patent if the business process employs the use of a new, nonobvious and tangible computer system, but the protection would have to focused on the tangible computer system that employs an overarching architecture and not the process.
