Xerox has filed a lawsuit against Hewlett Packard seeking to stop the company from selling inkjet printers that use thermal printing technology allegedly patented by Xerox.
Xerox' main bone of contention is with the actual inkjet cartridges and print heads contained within HP's Deskjet, Officejet Pro and Photosmart products, which it claims it developed and patented. Xerox wants HP to stop selling the products until the patent has been proven and subsequent licensing agreements have been issued.
An HP spokesman in the US said he was "surprised" by the lawsuit, especially as "HP has been developing inkjet technology since the late 1970s". He added that HP is now reviewing the technology and patents for its products and will make a response to the Xerox charges next week.
The move by Xerox comes at a time when the company has been making great noises about protecting its intellectual property, as well as making aggressive product launches and pricing strategies in the small business and home office markets.
Today the company launched a range of personal copiers into the low end market and this has been preceded by laser printer price cuts, product repositioning and an internal restructure.
