Bausch and Lomb are involved in a lawsuit with Novartis which claims to have a patent on one of Bausch and Lomb's products called PureVision. On August 2, 2002, Bausch and Lomb announced to move the production from the US to Ireland since a request to continue making and selling its contact lenses in the US while it appeals a decision in the patent lawsuit was denied by a federal appeals court.
