Lexmark sues importers of laser cartridges for patent infringement

Tuesday 24. August 2010 - Lexmark International, Inc. (NYSE:LXK) announced today that it has filed a patent infringement complaint with the United States International Trade Commission (ITC) against 24 companies engaged in the manufacture, importation and sale of replacement cartridges for various Lexmark laser printers and multifunction devices.

The complaint alleges that these replacement cartridges infringe at least 15 U.S. patents owned by Lexmark. Lexmark is requesting that the ITC issue a general exclusion order banning the importation and sale of patent infringing laser cartridges by any entity.

In addition to the ITC complaint, Lexmark has also filed a related patent infringement complaint in the U.S. District Court for the Southern District of Ohio against the same defendants. The District Court complaint contains allegations similar to those in the ITC complaint and seeks injunctive relief, monetary damages and attorneys’ fees.
