Leggett & Platt Inc. (LEG) said that it has won an agreement to dismissal of a lawsuit by Vutek Inc. which challenged the validity of two of Leggett & Platt's U.S. patents on Leggett's groundbreaking technology for ultraviolet or UV curing of ink in superwide format ink jet printers. Vutek agreed to withdraw its challenges to the validity of both of the Leggett patents.
Vutek, a subsidiary of Electronics For Imaging, Inc. (EFII), sued Leggett & Platt in federal court for the Eastern District of Missouri in November 2007, initially alleging invalidity of Leggett's U.S. Patent No. 7,290,874 and later of Leggett's U.S. Patent No. 7,520,602. These patents were based on Leggett's invention of revolutionary methods for quickly curing UV ink under the print head of superwide ink jet printers.
