In Ex party Rodriguez, the BPAI rejected a patent applicant's means-plus-function (MPF) claims as indefinite for failing to provide any corresponding structures in the specification beyond a general purpose computer. That decision followed the Federal Circuit's Aristocrat holding that "simply disclosing a computer as the structure designated to perform a particular function does not limit the scope of the claim to 'the corresponding structure, material, or acts' that perform the function, as required by section 112 paragraph 6."
A patent examiner recently wrote-in to identify the fact that the BPAI has recently remanded dozens of pending appeals in light of Rodriguez. The remands use the following form language:
Claims ___ of the instant application contain functional language that may be indefinite under 35 U.S.C. § 112, second paragraph. See Aristocrat Techs. Austl. Pty Ltd. v. Int’l Game Tech., 521 F.3d 1328 (Fed Cir. 2008); Ex parte Rodriquez, 92 USPQ2d 1395 (BPAI 2009). On September 2, 2008, the Deputy Commissioner for Patent Examination Policy, John J. Love, issued a memorandum entitled “Rejections under 35 U.S.C. 112, second paragraph, when examining means (or step) plus function claim limitations under 35 U.S.C. 112, sixth paragraph” . . . Thus, there is a question as to whether claims ___, and the claims which depend upon these claims, meet the requirements of being definite under 35 U.S.C. § 112, second paragraph. . . . Accordingly, it is ORDERED that the application is remanded to the Examiner to determine if claims ___, and the claims which depend upon these claims, meet the requirements of 35 U.S.C. § 112.

receiving means for receiving a notification of a presence of a virus on a client data processing system through a communications link;
severing means for severing communication with the client data processing system through the communications link in response to receiving the notification; and
executing means for executing virus removal processes on the server data processing system.
