Terminal disclaimer

A terminal disclaimer (TD) is a statement filed by a patent owner under 35 U.S.C. §253 (paragraph 2) and 37 C.F.R. § 1.321(b) or (c) to disclaim or dedicate to the public the entire term or any portion of the term of an issued patent or patent to be granted. A TD may be filed for the purpose of overcoming a judicailly-created double patenting rejection.
