Copyright Alliance Executive Director Patrick Ross, who regularly finds himself at odds with Sohn's viewpoint, agreed that filling vacant IP positions are important and he has been pleased with the administration's appointments to date. His group, which represents major IP owners and content creators, was pleased to see two entertainment industry lawyers -- Thomas Perrelli and Donald Verrilli -- join the Justice Department. Sohn's group, the Computer and Communications Industry Association, the Consumer Electronics Association and other tech stakeholders complained in a letter to Obama that both previously represented "the concentrated copyright industries" and future appointments should be more evenhanded.
