Pessimistically speaking, I at first was thinking along the lines of you and Dave, but I now realize that such optimism may be a bit unfounded. As I posted on my 'blog, there has never really been any overlap between the patent system and the copyright system, and the two systems can't be mixed as they were set up with entirely different objectives and methods. So I had thought that by labeling "code" as "expression", we'd inevitably be removing it from the realm of patent.
