Green Mountain Glass wins $50.3 Million from rival


A jury sitting the US District Court for the District of Delaware has awarded $50.3 Million in damages in a patent infringement dispute between rival glass manufacturers.

The award for wilful infringement was handed down on 21 April. Green Mountain Glass’s patent (5718737) covers technology that allows glass manufacturers to use recycled glass of mixed colours.

Claims of infringement of another patent (6,230,521) were dismissed.

The damages that Ardagh Glass might eventually have to pay for its infringement could be trebled to more than $150 Million.

“We are gratified that the jury found in favour of our client,” said Susman Godfrey partner Justin Nelson, who acted as lead counsel to Green Mountain Glass.

The technology covered by Green Mountain’s patent allows glass manufacturers to use recycled glass known as mixed color cullet.

This allowed Ardagh to save money on raw materials and energy, reduce emissions and extend glass furnace life when compared with the use of other raw materials, according to Green Mountain

The suit alleged that Ardagh made use of this technology without licensing it from Green Mountain.
