Printer Ink Maker Lexmark to Sue Replacement Cartridge Manufacturers
Printer ink firm Lexmark has announced it is to sue several replacement cartridge makers that, in its view, are committing patent infringement. The Kentucky firm announced it had filed legal notices with the US International Trade Commission (ITC) and the US District Court for the Southern District of Ohio last Friday.
Both claims are similar, and are against 24 companies that are involved in the manufacture, importation and sale of replacement cartridges for a range of Lexmark laser printers and multifunction devices.
The ITC complaint argues that the replacement ink cartridges sold by these firms infringes at least 15 patents owned by Lexmark. The firm wants the ITC to issue an exclusion order that will ban the import and sale of cartridges that infringe said patents.
The District Court complaint contains allegations similar to those in the ITC filing and seeks equitable relief, monetary damages and the payment of representatives' fees.
