Read MoreHow does the MPEP address computer-implemented means-plus-function limitations?
The MPEP provides specific guidance for computer-implemented means-plus-function limitations, particularly regarding the written description requirement. According to MPEP 2185: “If the means- (or step-) plus-function limitation is computer-implemented, and the specification does not provide a disclosure of the computer and algorithm in sufficient detail to demonstrate to one of ordinary skill in the art that…
Read MoreWhat are the key considerations for computer-implemented inventions under 35 U.S.C. 112?
For computer-implemented inventions, there are several key considerations under 35 U.S.C. 112, particularly regarding written description and enablement requirements. The MPEP 2185 highlights: “If the means- (or step-) plus-function limitation is computer-implemented, and the specification does not provide a disclosure of the computer and algorithm in sufficient detail to demonstrate to one of ordinary skill…
