Cohen Milstein Sellers & Toll, the District-based plaintiffs law firm with about 80 attorneys in five U.S. offices, has acquired Leopold Law, a five-attorney Florida firm.

Cohen Milstein, which brings class action lawsuits against companies in product liability, personal injury and managed care abuse cases, will keep its name. The move boosts the firm’s Palm Beach Gardens office.

The firms have worked together on cases before, including a gender discrimination class action against Wal-Mart that was filed in 2012 and dismissed last year.

“Both firms share a common commitment to providing assistance to victims of widespread and major fraud and abuse and to curbing the conduct that caused that harm,” Joseph Sellers, chair of the firm’s executive committee, said in a statement.

Patton Boggs banking lawyer joins Manatt

Banking lawyer Carol Van Cleef has left Patton Boggs for Manatt Phelps & Phillips.

The move comes as Manatt looks to grow its financial services regulatory group in Washington. Van Cleef was a partner at Patton Boggs, where she led the firm’s emerging payments and anti-money laundering compliance practices. She represents credit unions and other institutions on issues including consumer protection, data security, electronic payments and digital and virtual currencies. She also designs anti-money laundering programs.

“Growing our national financial services, privacy and data security practices, particularly in the area of electronic payments, is a strategic goal for the firm,” said Manatt managing partner Bill Quicksilver.
