Lewis R. Clayton - Paul, Weiss, Rifkind, Wharton & Garrison LLP

Within: M&A litigation: defense

Paul, Weiss, Rifkind, Wharton & Garrison LLP in New York has 'an excellent group of corporate litigation attorneys who are valued counselors and can be aggressive litigators when necessary'. Lewis R. Clayton and Andrew Gordon, who is 'an up-and-coming litigation star', scored a major victory for German healthcare group Fresenius when the Delaware Court of Chancery ruled that it was justified in canceling its agreement to acquire Akorn, Inc. for  $4.8bn. The firm's deep bench has 'tons of experience, superior judgment and excellent strategists'. Among the highly regarded practitioners are Jaren Janghorbani, who was part of the team that acted for Alere in claims arising from the cancellation of its $8bn sale to Abbott Laboratories in 2016; and Geoffrey Chepiga, who scored significant wins both in Delaware and in federal district courts. Of counsel Stephen Lamb, who is a former vice-chancellor in the Delaware Court of Chancery, has a strong practice in Wilmington.
