What is the difference between functional limitations and means-plus-function claim language?
While both functional limitations and means-plus-function claim language describe elements by their function, there are important differences:
- Means-plus-function claims are a specific form of functional claiming authorized by 35 U.S.C. 112(f).
- Means-plus-function claims are interpreted more narrowly, limited to the structure disclosed in the specification and its equivalents.
- General functional limitations can be broader and are not necessarily limited to specific structures in the specification.
