Philadelphia-based Schnader Harrison Segal & Lewis has hired Salem Katsh as a partner in its New York intellectual property practice. Katsh previously chaired the IP groups at Weil, Gotshal & Manges and Shearman & Sterling. More recently, he was the chair of the IP group at Kasowitz, Benson, Torres & Friedman from 2005 to 2006 before leaving to become a solo practitioner. “I spent God knows 30 something years in the mammoth law firms, and I decided I wanted to try something on my own,” said Katsh, 61.

After two-plus years on his own, Katsh said he “missed the camaraderie and collegiality of a law firm.” He did not want to go back to a large law firm and instead zeroed in on Schnader, a 200-lawyer firm with what Katsh called “a deep patent bench.” Schnader has 27 lawyers in New York, according to its Web site.
