How are computer-implemented means-plus-function limitations interpreted?
For computer-implemented means-plus-function limitations, the specification must disclose an algorithm for performing the claimed function. The MPEP states:
“For a computer-implemented 35 U.S.C. 112(f) claim limitation, the specification must disclose an algorithm for performing the claimed specific computer function, or else the claim is indefinite under 35 U.S.C. 112(b).“
A general-purpose computer is not sufficient structure for a computer-implemented function. The algorithm may be expressed in various forms, including as a mathematical formula, in prose, or as a flow chart.
