A Delaware federal judge on Wednesday expressed skepticism at Groupon Inc.’s attempt to roll back an $82.5 million verdict for willfully infringing four IBM patents that date back to the early days of the internet and called for a speedy close to post-trial briefing.

In a two-page letter, U.S. District Chief Judge Leonard P. Stark of the District of Delaware said he was “inclined” to deny Groupon’s expected motion for a new trial, as well as a range of other maneuvers to attack last month’s verdict in a case that’s been closely watched by the tech industry.
