MAKER OF EXPENSIVE PRINTER INK HP has filed a lawsuit to sue four printer ink cartridge companies for patent infringement, according to Businessweek.

The patent infringement case rests on cartridges sold by printer ink cartridge maker Microjet and three other manufacturers. HP alleged in a complaint filed in US federal court that all four companies "converted more than 300,000 genuine HP printheads from HP facilities in Asia", then sold them as products manufactured by another company, Mipo Technology.

Microjet did not have much of a response to HP's lawsuit. Microjet spokesman John Kuo said only, "Our lawyers are currently investigating the situation." He did say the company had not been contacted by HP before it filed the lawsuit and that he only found out about the case yesterday.

In its complaint, HP asked the court to bar the companies from infringing its patents and requested unspecified damages. µ
