Morgan Lewis & Bockius has hired a further 525 lawyers, legal professionals and staff from Bingham McCutchen, ten days after voting to admit 226 partners from the Boston-headquartered firm, which is now set to dissolve.

The hires make Morgan Lewis one of the largest law firms in the US by headcount, a move which the firm said gives it "a dominant presence along the East and West coasts of the United States".

"We are delighted that our new colleagues have today joined our efforts to create a new global powerhouse that delivers the highest quality results and advances our clients' legal and business interests – from New York to Tokyo, London to San Francisco, Silicon Valley to Moscow, and points in between," said Morgan Lewis chair Jami McKeon, in her first public statement on the Bingham deal.

McKeon said the move gave Morgan Lewis additional resources in environmental litigation, securities enforcement, project finance, restructuring, tax, intellectual property and antitrust.

The firm said legacy Bingham clients would have access to further support in white collar, corporate transactional, labour and employment, energy, immigration and healthcare matters, as well as new offices including Houston and Chicago.

Bingham managing partner Steve Browne, who is making the transfer alongside the bulk of his colleagues and partners, called Morgan Lewis "a perfect new firm" for the group. Bingham's website currently lists 164 counsel or of counsel, and 184 associates.

"We already serve many of the same clients, but we will now have the added resources to assist them in new ways and in new markets, including in Europe and Latin America, and in the center of the United States," he said. "This is a very exciting day for our clients and us."

The acquisition leaves Bingham – for the time being – with around 80 partners, who are set to seek roles at other firms, retire or, in a few cases, join Morgan Lewis as non-partner lawyers.

New bases for Morgan Lewis include Santa Monica and Hartford, Connecticut. Last week, sources told Legal Week that Bingham's Hong Kong office will also move over, though licensing issues mean it must operate as a stand-alone operation while the Philadelphia firm receives approval from the state's Law Society.

Prior to its acquisition by Morgan Lewis, Bingham had a torrid 18 months after seeing revenue fall by 12.6% to $762m (£456m) in 2013, a general loss of confidence in the firm's strategic direction in sections of the partnership, high-profile partner exits, and cuts to junior lawyer numbers.
