Merger Updates: Wildman, Harrold Allen & Dixon, a 211-lawyer Chicago-based law firm, is actively looking to acquire or merge with another law firm, according to several legal sources. One said the search had become heated of late, with the firm hiring a consultant to sift options.

While declining to discuss specific plans, managing partner Robert Shuftan noted Wildman has added 25 to 30 partners in the last two years. "We're looking at further opportunities to expand, both in Chicago and elsewhere,'' he said.

Perkins Coie LLP, the largest law firm in the Puget Sound area with approximately 550 lawyers firmwide, is merging with Phoenix-based Brown & Bain, a firm known for its work in intellectual property and complex litigation.

The merger will close July 1 and make Phoenix the second-largest office for Perkins Coie. The firm's largest office is in downtown Seattle
