Mintz, Levin, Cohn, Ferris, Glovsky and Popeo has added Siegmund “Sige” Gutman, Proskauer Rose’s life science patent practice chair, to its roster in Los Angeles. He’s part of a two-partner, 10-attorney move that helps Mintz bolster its life sciences presence in Los Angeles, Boston and New York, the firm said Monday.

Gutman will assume the roles of chair of life sciences litigation as well as co-chair of the firm’s patent litigation group. The firm said in a release that Gutman will be joined by member David Hanna and eight other attorneys in Los Angeles, Boston and New York. (Member is Mintz’s parlance for partner.)
