Ex parte Bo Li - This November 6, 2008 decision was the first decision from the Board of Patent Appeals and Interferences to address a computer readable medium claim after the ruling in In re Bilski.  The Board found that the claim should no longer be rejected under the In re Bilski test.  Ex parte Bo Li blog entry

Ex parte Cornea-Hasegan -  On January 13, 2009 the Board of Patent Appeals and Interferences found that "the recitation of a 'processor' fails to impose any meaningful limits on the claim's scope" and, therefore, "is insufficient to establish patent-eligibility under 35 U.S.C. § 101," according to the In re Bilski decision.

Ex Parte Gutta - On January 15, 2009 the Board of Patent Appeals and Interferences found that "the recitation in the preamble of '[a] computerized method performed by a data processor' adds nothing more than a general purpose computer that is associated with the steps of the process in an unspecified manner."  They also found that step of "displaying" the result to a target user in claim 1 is a post-solution activity insufficient to impart patentability.

Ex parte Barnes - On January 22, 2009 the Board of Patent Appeals and Interferences found that the claims "call for the gathering, analyzing and displaying of data without any details as to how the data is gathered, analyzed or displayed."  This case is interesting because a § 101 rejection was not before the Board, but they entered it as new grounds for rejection. U.S. Publication No. 20060133206

Ex parte Becker - On January 26, 2009 the Board of Patent Appeals and Interferences found that "Appellants’ claimed 'method for creating a hierarchically structured automation object and embedding said automation object into an engineering system' (see preamble, claim 7) does not require a particular machine or apparatus, nor do these claims transform any article into a different state or thing."  In this case also a § 101 rejection was not before the Board, but they entered it as new grounds for rejection.  This case is interesting because claim 7 included modules, but was still rejected.  U.S. Publication No. 20020072819

Ex parte Atkin - On January 30, 2009 the Board of Patent Appeals and Interferences found that a method and system for converting a unidirectional domain name to a bidirectional domain name were unpatentable under 35 U.S.C. § 101.  The Board found that a "domain name is simply a series of characters representing the address of a resource, such as a server, on the World Wide Web." The Board reasoned that the ruling in Bilski was also applicable to a system claim, because the "term 'system' in the preamble is broad enough to read on a method and thus does not imply the presence of any apparatus."
