Batman and Superman are still fighting in movie theaters, but a battle over plastics technology that was used in comic books featuring those characters has ended.
The legal conflict over lenticular technology was between Dynamic Drinkware LLC of Oshkosh, Wis., and Waukesha, Wis.-based National Graphics Inc. On March 31, the two firms announced that Dynamic has purchased National's patent portfolio, officially ending the dispute. No purchase price was disclosed in the deal.
The patents cover molded articles such as cups and bottles that bear a lenticular image. Images printed on a lenticular lens are transformed from static images into dynamic art through special effects. In 2013 and 2014, DC Comics used National's 3-D motion technology to create amorphous PET film covers featuring Superman, Batman and other characters.
The purchase also ends similar disputes between National and competitors Service Litho-Print Inc. and Brax Ltd. U.S. District Court Judge William Greisbach granted a motion in January confirming that Dynamic and the two other firms did not infringe on three lenticular patents filed by National.
