Hoover has had to abandon its Triple Vortex cleaner after a High Court judge granted the rival Dyson Appliances an order banning its sale because of patent infringement.

But Hoover said it would launch a new model, the Vortex Power, on Monday. Like the Dyson, it is bagless. Hoover said it will not fall foul of the law.

Yesterday's decision follows a ruling earlier this month in favour of James Dyson, the inventro who said the Triple Vortex infringed his Dual Cyclone's patent. Deputy High Court Judge Michael Fysh QC yesterday granted an injunction banning Triple Vortex sales until Mr Dyson's patent ends in June.The judge granted Hoover permission to appeal.

Peter Prescott QC, for Mr Dyson, had told the judge Hoover was given at least a 12-month advantage in developing its bagless cleaners, because it infringed a patent.

Christopher Floyd QC, for Hoover, said it was recalling the Triple Vortex models from dealers. Its patent-infringing machinery would be scrapped and the new system installed.

Hoover has to pay a £200,000 advance towards Mr Dyson's costs. More damages arising from the patent infringementhave to be assessed. The judge said he would reserve judgment on extending the sales ban for another 12 months and on whether to bar Hoover from using the Vortex trademark.
