Canon announces conclusion of toner cartridge patent lawsuit in United States

Canon announced the conclusion of a patent infringement dispute with V4INK, Inc. in the U.S. District Court for the Central District of California concerning toner cartridges sold for use in various models of Canon and HP laser beam printers.

As a result of the lawsuit, the court issued a permanent injunction prohibiting V4INK from making, using, selling and offering for sale in the United States, and from importing into the United States, the toner cartridges that Canon accused of infringement.

Canon had filed suit against V4INK on May 7, 2019, for infringement of Canon’s U.S. Patent Nos. 7,869,740; 8,165,494; 8,588,646; 8,971,760; 9,494,916; 9,857,763; and 10,162,304. On October 21 , the Court entered default judgment and issued a permanent injunction against V4INK, permanently enjoining V4INK’s activities relating to the accused products and any other products that infringe any of these patents and are not more than colorably different from the accused products.

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.
