3M wins patent injunction

3M has secured a permanent injunction in the United States District Court of Minnesota against Avery Dennison.


3M Company and 3M Innovative Properties, a wholly owned subsidiary of 3M, have secured a permanent injunction in the United States District Court of Minnesota against Avery Dennison Corp.

The injunction, granted on March 17, 2006, prohibits Avery Dennison from making, using, selling or importing into the United States its EZ Series Fleet Marking Film.



In December 2005, a jury found that Avery Dennison had infringed on 3M’s patent, which relates to release liners used in the manufacture and sale of pressure sensitive adhesives for large format graphics by selling its EZ Series Fleet Marking Film.



3M’s patented technology is used in the manufacture of 3M Controltac Plus Graphic Film with Comply Adhesive, a product that allows graphics to be applied more quickly and consistently, reducing wrinkles and bubbles throughout the application process.



“3M makes a significant investment in research and development each year,” said Bob Doughty, division vice president, 3M Commercial Graphics Division. “The court’s decision helps to protect that investment and to ensure that we can continue to provide our customers with the products they need to be successful.”
