Honeywell on Wednesday announced that it has filed suit in federal court against Apple Computer Inc. and more than thirty other companies, alleging infringement over a 1994 patent that describes technology used to improve the quality of images shown on a Liquid Crystal Display (LCD) panel. MacCentral has obtained a copy of the documents Honeywell filed on October 6, 2004 in U.S. District Court for the district of Delaware. Honeywell alleges that Apple and the other defendants are violating U.S. Patent 5,280,371. Filed in July of 1992 and granted in January, 1994, the patent describes a "directional diffuser for a liquid crystal display."
