LEXINGTON, Ky. (AP) -- Printer maker Lexmark International Inc. said Monday it has filed a patent infringement complaint with the U.S. International Trade Commission against 24 companies.
Lexmark said the companies engaged in the manufacture, importation and sale of replacement cartridges for the company's laser printers and multifunction devices.
The complaint alleges that these replacement cartridges infringe on at least 15 U.S. patents owned by Lexmark. Lexmark said it is requesting that the ITC issue a general exclusion order banning the importation and sale of patent infringing laser cartridges.
Shares of Lexmark fell 9 cents to $37.17 in midday trading.
