Bobby Burchfield, head of the complex litigation group at McDermott Will & Emery, has left the firm with fellow litigation partner Matthew Leland for King & Spalding.

The moves comes after two top IP litigation partners left McDermott in Silicon Valley and Washington, D.C., for Paul Hastings, as noted by sibling publication The Recorder, and McDermott’s hire of Holland & Knight’s international private client practice head Leigh-Alexandra Basha.
