UPDATES: 10/15/13, 6:10 p.m. EDT. A statement from a Cox spokesman has been added to the 11th paragraph of this story. 10/16/13, 9:45 a.m. EDT. The Recorder, a sibling publication, has more on Cooley’s merger with Dow Lohnes. Correction. 10/16/13, 6 p.m. EDT: The original version of this story included an incorrect figure for the number of lawyers Cooley will have once it adds the Dow Lohnes attorneys it is absorbing. The correct figure is 750. The abstract and 17th paragraph of this story have been revised to include the correct information. We regret the error.

Cooley and Dow Lohnes announced Tuesday that they will merge as of January 1 in a deal that secures a new home for 54 lawyers—including 15 partners—from the latter’s headquarters in Washington, D.C.
