Canon announces successful resolution of toner cartridge patent infringement lawsuits against Print-Rite in U.S. and Germany

TOKYO, September 5, 2023—Canon Inc. announced today that it and Print-Rite have agreed to resolve a lawsuit that Canon filed earlier this year in the U.S. District Court for the District of Delaware against Print-Rite Imaging Technology Inc. and Union Technology International (MCO) Co. Ltd. for infringement of Canon's U.S. Patent No. 11,169,483, as well as a lawsuit that Canon filed on the same day in the District Court of Düsseldorf in Germany against Print-Rite Unicorn Image Products Co., Ltd. of Zhuhai, Union Technology International (MCO) Co., Ltd., and Unideatec S.a.s. for use of the German portion of Canon's European Patent No. 3 470 931 B1.

To resolve the lawsuits, Print-Rite acknowledged its infringement of the asserted patents and agreed to pay Canon an undisclosed amount to compensate Canon for such infringement. Print-Rite also agreed to entry of a Consent Judgment and Permanent Injunction from the Delaware court and issuance of a Judgment of Acknowledgement from the Düsseldorf court acknowledging that all claims asserted by Canon are justified in whole. As a result, Print-Rite is prohibited from making, using, selling, and offering for sale in the U.S. and Germany, and from importing into those countries, the HP-compatible toner cartridges that Canon accused of infringement, including but not limited to Print-Rite models CF248A and CF244A.

Throughout the development, sales, and marketing process, Canon respects the intellectual property of other companies and individuals and expects others to similarly respect Canon’s intellectual property rights. Canon remains committed to pursuing legal enforcement against those who do not respect Canon’s intellectual property.
