The competitive New York IP litigation market continues to be a key focus for two big Atlanta-based firms, King & Spalding and Troutman Sanders.

Troutman announced on Thursday that it had recruited two seasoned IP litigation partners, Joe Diamante and Chuck Cantine, from King & Spalding’s New York office. Meanwhile, King & Spalding said the same day that it landed two other IP litigation partners, Steven Rizzi and Ramy Hanna, from Foley & Lardner, who focus on tech and pharma patent disputes.
