IBM has asked a federal judge in Delaware to double an $82.5 million jury verdict in July against Groupon for willfully infringing four patents dating back to the early days of the internet.

In a court filing made public Wednesday night, attorneys for IBM said that Groupon never took seriously the company's patents rights and engaged in a “pattern of delay and neglect” before and during the lawsuit.

The jury's finding of willful infringement, they said, warranted a doubling of damages to $165 million and an ongoing royalty in the tens of millions of dollars to compensate IBM for its continued use of two IBM's patents, which are set to expire in 2023 and 2028. IBM is also seeking interest and attorney fees for having to litigate the case.
