Law - Best Mode of the Invention

U.S. patent law requires that at least the "best mode" of the invention be disclosed. It is prudent, however, to include in the specification at least a mention of all conceivable alternatives to the mode that is considered the best mode at the time of filing of the patent application. This will make it more difficult for other inventors to obtain patents on improvements to the present invention and could facilitate obtaining broader claims.
