Vutek to withdraw its challenges to validity of Leggett patents
Nov '09
Leggett & Platt, Incorporated, a diversified manufacturer of engineered components including the Virtu line of superwide digital printers for solid and textile substrates, 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 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., 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. The U.S. Patent & Trademark Office issued one of the patents after full review of an earlier appellate court decision declaring a related patent invalid, thus recognizing the importance of Leggett's invention of the first practical 'on the printhead' UV ink curing technology for superwide inkjet printers. The leading printing association, the Specialty Graphic Imaging Association also recognized Leggett's pioneering technology by awarding the 2006 DPI Innovator Award to Leggett's inventor, Mr. Richard Codos.

Leggett & Platt is a FORTUNE 500 diversified manufacturer that conceives, designs and produces a broad variety of engineered components and products that can be found in most homes, offices, and automobiles. The company serves a broad suite of customers that comprise a "Who's Who" of U.S. manufacturers and retailers. The 126-year-old firm is comprised of 19 business units, 19,000 employee-partners, and more than 160 manufacturing facilities located in 18 countries.
