Groklaw Says Microsoft Patent Portfolio Now Worthless

twitter writes "P.J. concludes her look at the Bilski decision: 'you'll recall patent lawyer Gene Quinn immediately wrote that it was bad news for Microsoft, that "much of the Microsoft patent portfolio has gone up in smoke" because, as Quinn's partner John White pointed out to him, "Microsoft doesn't make machines." Not just Microsoft. His analysis was that many software patents that had issued prior to Bilski, depending on how they were drafted, "are almost certainly now worthless." ... He was not the only attorney to think about Microsoft in writing about Bilski.'"

Bilski wasn't about software patents

[The Empiricist]

Bilski was about business method patents not tied to any machine. The Federal Circuit tried to make this clear in the In re Bilski opinion itself (page 21):

We further reject calls for categorical exclusions beyond those for fundamental principles already identified by the Supreme Court. We rejected just such an exclusion in State Street, noting that the so-called "business method exception" was unlawful and that business method claims (and indeed all process claims) are "subject to the same legal requirements for patentability as applied to any other process or method." 149 F.3d at 1375-76.[Fn23 Therefore, 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.]

It is true that the validity of many broadly drafted claims may be at issue, but many software claims just do not make sense unless the claims are understood to be tied to computational devices. For example, Beauregard claims, which are claims on a computer readable media adapted to implement a method or system, are considered patentable by the PTO. These kind of claims are very popular because they allow patent holders to go after the software distributors rather than end-users.

It will be harder to enforce software patents, now that the defense lawyers can wield Sec. 101 with more power. But it is a mistake to declare victory against software patents based on a case where all the PTO wanted was for the patent applicant to add "computer implemented" to the claim language.

no, NT was a rename of the OS/2 3.0 development snapshot which Microsoft ended up with after their spat with IBM in the early 1990's and continued to evolve into the NT kernel, which they first used in NT3.1, released on 27 July 1993.

The reason NT started at version 3 is because versions 1 and 2 were already released as the collaborative effort and named OS/2 versions 1 and 2.
