Orrick Herrington & Sutcliffe has added veteran intellectual property litigator Irena Royzman to its roster in New York, the firm said Monday. Royzman had been the head of Kramer Levin Naftalis & Frankel’s life sciences practice.

“Irena’s extraordinary scientific credentials and winning litigation record have earned the trust of the world’s leading life sciences companies,” Alyssa Caridis, co-head of Orrick’s IP business unit, said in a statement. “We see her as another game-changing addition to our growing national team handling cutting-edge cases.”
