FUNCTIONAL LIMITATION
functional limitation.Patents. In a patent application, the definition of an invention by what it
does rather than what it is. • A functional limitation is not inherently invalid, but it is examined
closely because it tends to be too broad, claiming every possible way of doing the same thing.
