Hewlett Packard has notified Cartridge World North America that it has discovered patent breeches in ink cartridges sold by a number of stores across the US.
According to reports the patent infringements were discovered after routine testing and enforcement procedures taken by HPÂs Imaging and Printing Group, in a bid to protect the companyÂs IP rights.
Following similar testing in March this year, HP discovered patent infringements in a number of cartridges sold under the Staples brand however the company agreed to alter its ink formulations.Â
According to the senior vice president of supplies at HPÂs Imaging and Printing Group: Â
ÂHP spends millions of dollars annually in R&D to create innovations that benefit our customers,Â and we are rigorous in our protection of this investment. HP hopes that Cartridge World NorthÂ America will assist its franchisees in quickly complying with the law.Â
In a separate action involving Hewlett Packard, a settlement has been reached with Rhinotek over claims of false advertising and unfair competition. Rhinotek refilled HP cartridges for resale, but failed to state on the packaging that it had done so.
According to research undertaken by HP, over half of RhinotekÂs customers were unaware that the cartridges sold had already been used and were merely refilled before being resold. Â
Rhinotek denied any wrong doing, but nonetheless agreed to alter the packaging so as to expresslyÂ inform its customers that the ink cartridges for sale are refilled.
