DLA Piper Rudnick Gray Cary LLP, the second-biggest U.S. law firm by number of attorneys, plans to double the number of its European lawyers to 1,000 by 2009 to handle corporate, regulatory litigation and patent work. DLA Piper, based in Baltimore and London, is considering a new office in Munich, Germany, and expansion in Frankfurt, Germany, and Madrid, Spain, Peter Wayte, London-based senior partner for Europe and Asia, said in an interview. The Paris office will likely grow from 20 to 100 lawyers in three years and Scandinavia by 150 if DLA Piper can find the right candidates, he said. .
