Nine years ago the Federal Circuit breathed new life into the defense of prosecution laches in Symbol Technologies, Inc. v. Lemelson Medical, Education & Research Foundation, 277 F.3d 1361, 1363 (Fed. Cir. 2002). The defense requires a showing of “unreasonable and unexplained delay” in prosecution and prejudice to the accused infringer. As applied to individual cases, much of the burden of interpreting whether a delay is “unreasonable and unexplained,” or the extent to which a defendant is harmed by such a delay, is left to the discretion of the court. Because of this, tracking recent court decisions on prosecution laches could provide unique insight when asserting or opposing a prosecution laches defense.
