Warburg has hired Evercore Partners to manage the sale, said Reuters, citing people familiar with the matter.
IParadigms has an EBITDA of around $50m and will likely be sold for 15 times that, or $750m, said some of the sources.
Warburg bought a controlling stake in iParadigms, whose software helps prevent plagiarism, verify content, and evaluate written work, in 2008.
Earlier this year the New York-headquartered private equity firm sold its investment in specialty pharmaceutical company JHP Group to Par Pharmaceutical Companies for a return of three times.
