Appeal No. 97-0032 Application No. 08/095,295 As is apparent from our patent jurisprudence (e.g., Valmont Industries Inc. v. Reinke Manufacturing Co. Inc., 983 F.2d 1039, 1042, 25 USPQ2d 1451, 1454 (Fed. Cir. 1993)) and from the Manual of Patent Examining Procedure (e.g., § 2182), the application of a prior art reference to a "means plus function" limitation requires (1) that the prior art element or structure perform the identical function specified in the claim and (2) perform that function using structure which is the same as or equivalent to the structure disclosed in the specification. If the prior art fails to teach or suggest identity of function to that specified in the claim and the element or structure of the prior art as disclosed is not capable of performing such function, then the inquiry is over and the prior art reference does not meet the "means plus function" limitation specified in the claim. Since the snap fasteners (32, 33) of the Warren patent clearly do not and can not perform the function specified in appellants' claim 33, it is clear that the examiner's rejection of claim 33 can not be sustained. Given my determination that the snap fasteners (32, 33) of Warren do not and can not perform the identical function specified in claim 33 on appeal, I see no need to reach the issue 2929Page: Previous 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 NextLast modified: November 3, 2007
