Eisai v. Sanofi-Aventis U.S., LLC, No. 08-4168 (MLC), 2012 WL 1299379 (D.N.J. Apr. 16, 2012)

Key Insight: Court denied plaintiff?s motions to compel discovery from an additional 175 custodians and an additional 27 custodians (two separate requests) upon its determination that the requests were cumulative or duplicative and that the burden outweighed the potential benefit; of note was the significant expenditures of the defendants on already-produced discovery and the volumes produced as well as the estimated cost of the additional requested discovery, where the estimated burden of producing the additional 175 custodians was 140,00 hours of manpower and roughly $15 million dollars?an amount that exceeded the expected value of plaintiff?s claim

Electronic Data Involved: ESI from 200+ custodians
