CORRECTION: 2/28/14, 12:55 p.m. EST. The original version of this story referred inaccurately to the total revenues earned by Patton Boggs’ Newark office and those revenues specifically tied to the 9/11 captive insurance case handled by the firm. The 24th paragraph of the story has been revised to reflect the correct information. We regret the error.

When litigators and longtime friends James Tyrrell Jr. and John McGahren led a 25-lawyer group from Latham & Watkins to Patton Boggs in 2006, their new firm was effusive in its praise.
