scales of justice 2April 20, 2015 – Canon Inc. reports that it’s successfully resolved a patent-infringement dispute with Printronic Corporation in the U.S. District Court for the Southern District of New York, concerning certain toner cartridges and image drums. Canon had accused of Printronic of infringing upon its U.S. Patent Nos. 5,903,803 and 6,128,454 with the third-party toner cartridges and image drums sold by Printronic.

Printronic has stipulated to a consent judgment and permanent injunction issued by the Southern District of New York. The measures prohibit Printronic from making, using, selling and offering for sale in the United States, and from importing into the United States, the toner cartridges and photosensitive drums that Canon says infringes upon its patents.
