Everyone knows that HP makes its money on ink cartridges, and that subsidises the complex technology in its printers.
But HP jealously guards its patents on ink cartridges and filed a complaint against a number of Chinese and other companies that it claimed breached patents it owned on designs.
HP complained to the International Trade Commission (ITC) on the 23rd of September 2009, alleging violations of the US 1930 Tariff Act.
The complaint investigated a number of companies including Zhuhai Gree Magneto-Electric of China, InkPlusToner.com, SmartOne Services LLC, Comptree, ABCInk, EZ Label, CDR DVDR Media, Mipo International, Mextec Group, Shanghai Angel Printer Supplies, Shenzhen Print Media, Zhuhai National Resources, Tatrix International, and Ourway Image Co.
HP said that InkPlusToner and Comptree have settled with HP by paying a sum of money to the company, and said both of these firms will stop making and selling HP O2 compatible inkjet supplies.
Others have been prevented from importing cartridges that infringe the HP patents.
Stephen Nigro, senior VP of HP’s Inkjet business unit, said it will purse others that don’t respect its intellectual property rights.
