Boston-based law firm Mintz, Levin, Cohn, Ferris, Glovsky, and Popeo PC said that it has expanded its intellectual property practice by hiring three partners from Nutter McClennen & Fish, another firm.

William (Bill) C. Geary III, Lisa Adams, and Christina Sperry have joined as members of Mintz Levin’s Boston office, the firm said in a Thursday press release.

Over the course of their careers, Geary, Adams, and Sperry have represented Johnson & Johnson and Massachusetts General Hospital as well as many start-ups, medical device manufacturers, and medical and research institutions, the firm said.

“The need for sophisticated intellectual property capabilities has never been greater as companies, particularly in medical technology and life sciences, continue to develop breakthrough innovations and seek access to the public markets,” Robert Bodian, managing member of Mintz Levin, said in a statement.


Mintz Levin’s press release also included a statement from Geary.

“We are thrilled to be joining a firm with a national and international presence that will provide a broad platform for our clients and a deep bench of talent, not only with respect to prosecution, but in the corporate and litigation areas as well,” Geary said.

In a statement wishing their former colleagues well, Nuttern McClennen & Fish noted that in today’s “fluid” legal environment, lateral moves between firms are not unusual.

“With deep roots, a strong base of loyal clients, and a team of great lawyers, we are well positioned to navigate changes,” Nutter McClennen & Fish said.
