Thelen Reid Brown Raysman & Steiner is losing another of its name partners, Richard Raysman. The tech and intellectual property attorney’s departure to New York’s Otterbourg Steindler Houston & Rosen comes on the heels of a host of defections, including that of name partner Peter Brown and five practice heads.

Both Raysman and Brown came from Brown, Raysman, Millstein Felder & Steiner, the 250-attorney, tech-savvy firm that merged with the larger Thelen in late 2006.
