The Federal Circuit today upheld a summary judgment against the holder of a patent on a "Method and Apparatus for Ink Jet Printing on Rigid Panels". The court held that an earlier patent "anticipated" several claims in Leggett & Platt’s Patent No. 6,755,518 and that disclosures in the old patent made claims in the ‘518 patent "obvious". The patents, as best Blawgletter can tell, relate to squirting ink and then quickly drying it with "cold" ultraviolet radiation. Sounds nifty. Leggett & Platt, Inc. v. Vutek Inc., No. 07-1515 (Fed. Cir. Aug. 21, 2008).
