Lexmark sues importers of laser cartridges for patent infringement

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.
