Philadelphia law firm Blank Rome LLP is hiring roughly 100 lawyers from Dickstein Shapiro LLP, a once-stalwart Washington, D.C., law firm that has been on shaky ground for years, the Wall Street Journal reported today. The deal, which includes lawyers in New York and D.C., will create a law firm with more than 620 attorneys in 13 U.S. offices and in Shanghai. The combination doesn’t include Dickstein’s Los Angeles office. The announcement, made yesterday, comes after weeks of defections from Dickstein, which dropped in size from around 350 lawyers a few years ago to less than 120 as of this month. Recent departures include Dickstein’s entire Connecticut office, which moved its practice to Holland & Knight LLP.
