Profits per partner: $3,125,000
This Manhattan-based law firm, often known as just Skadden, was first introduced to the world in 1948 by three young lawyers namely Marshall Skadden, John Slate and Les Arps. Skadden did not take long to establish itself in the world of law. In the late 60s and early 70s, the firm earned a name for itself as an expert of hostile takeovers and tender offers, and subsequently an expert of corporate law in general.
Skadden then focused on its expansion, setting up an office in Boston in 1973. Today, it has a total of 22 offices scattered around the world, in major cities of various countries like France, China, and Japan.
The gross revenue of Skadden amounts to a whopping $2.4 billion. Couple that with its humongous size and it can comfortably be regarded as one of the most successful law firms.
