Troutman Sanders said Tuesday it is expanding its New York office by hiring five intellectual property lawyers who were left adrift after the abrupt collapse in December of Dreier LLP.

The group, led by senior patent litigator Albert Jacobs Jr., has had a bumpy ride. Jacobs brought his team to Dreier from Greenberg Traurig in 2007. But 18 months later, Marc S. Dreier was under arrest for fraud and Jacobs’ group was rushing to escape the fallout. “It’s not the way I wanted to spend my Christmas, let’s just say,” Jacobs said.
