Verner Liipfert and Piper Rudnick to merge

US firm Piper Rudnick is set to merge with Washington's Verner Liipfert Bernhard McPherson & Hand. Verner Liipfert, which specialises in public policy work, had formerly been in talks with McDermott Will & Emery. However, Piper Rudnick and Liipfert are now hoping to announce a merger within a matter of weeks.
