DLA Piper is now the biggest law firm in the world.

The firm saw $2.4 billion in revenue last year, which is an 8.6 percent jump since 2011 and makes it the highest-grossing firm in the world. DLA Piper also boasts more than 4,000 lawyers, more than any other firm.

DLA Piper just barely bumped Baker & McKenzie out of the top spot it had held since 2009. That firm raked in $2.3 billion last year and has almost as many lawyers.

Even though DLA Piper and Baker & McKenzie are the world's biggest firms, three other firms brought in almost as much money with fewer lawyers. In 2012, Latham & Watkins; Skadden, Arps, Slate, Meagher & Flom; and Kirkland & Ellis each brought in profits of more than $1 billion.
