The decision on the Bilski case has been published today by the specialized patent court in the US (CAFC - Court of Appeal of the Federal Circuit). The judges says that the Bilski case is not helpful to draw the line between what is patentable and what is not in the case of software patents (see footnote nr 23, pages 21 and 22):
although invited to do so by several amici, we decline to adopt a broad exclusion over software or any other such category of subject matter beyond the exclusion of claims drawn to fundamental principles set forth by the Supreme Court … We also note that the process claim at issue in this appeal is not, in any event, a software claim. Thus, the facts here would be largely unhelpful in illuminating the distinctions between those software claims that are patent-eligible and those that are not.
So business patents might be scraped, but software patents are still there in the US. IBM might be happy.
When is the next Bilski with a pure software patent?
