HP, Dell and Gateway face patent lawsuit

A mapping and GIS technology company has filed a lawsuit charging Dell, Hewlett-Packard and Gateway with patent infringement.

Intergraph told a US court that the three vendors infringed on at least three patents related to its Clipper cache memory management technology.

Intergraph won a suit against Intel in October when a judge ruled that its Itanium chip infringed Intergraph's Clipper patents. The ruling was expected to cost Intel $150m (£93.8m) in damages.

An earlier patent infringement case in April saw Intel paying Intergraph $300m and licensing Intergraph technology.

The settlement agreement with Intel did not include licences for Intel's customers, however, and specifically set out Intergraph's intention to seek payment for patent licences from manufacturers.
