Lionbridge Technologies Inc. on Wednesday slammed as “farcical” a lawsuit alleging that it and private equity firm H.I.G. had made a sham bid to buy rival TransPerfect Global Inc. in order to obtain its trade secrets.

In a 32-page filing, Lionbridge and H.I.G.’s middle-market arm asked U.S. District Judge Denise L. Cote of the Southern District of New York to dismiss TransPerfect’s suit, which seeks hundreds of millions of dollars in damages stemming from the leading translation-services firm’s forced sale in 2017.
