For all of last year, Heller Ehrman’s headcount grew by only 11. In a flurry of lateral hiring, the firm has already added more than that in the first two months of 2007, including nine new attorneys in its new London office alone.

On Tuesday, the firm announced the addition of five corporate lawyers in London and two IP litigators in Washington, D.C. In its latest London move, Heller raided Wilmer Cutler Pickering Hale and Dorr again, coming away with tax and benefits partner Christopher Prout, senior corporate associate Scott Leonard-Morgan and three other corporate associates.
