Midsize firm Cole Schotz, which has maintained a small outpost in Dallas since 2014, has more than doubled its size there with the addition of a four-lawyer intellectual property group.

The IP lawyers, led by partners Aaron Davidson and Gary Sorden, joined Cole Schotz’s Dallas office on Monday. They came from Klemchuk LLP, a small firm in Dallas that handles IP, litigation, technology and international business work.

Associates Brian King and Tim Craddock also joined Cole Schotz in Dallas, boosting the office to six lawyers. The firm also has two lawyers in Fort Worth, led by bankruptcy partner Michael Warner.

James Walker, a Cole Schotz partner who opened the Dallas office in 2014, said Davidson and Sorden are not only skilled litigators but “some of the nicest guys you will meet.”

“They have a lot of experience in the courtroom. They’ve picked a lot of juries, argued hearings and appeals—the kind of trial lawyers and practitioners we are really looking to build the office with,” Walker said.

Sorden said he and Davidson had decided recently that they needed to move their practice to a larger firm, and they were attracted to Cole Schotz’s roster of talented attorneys and its national reach.

The New Jersey-based firm has been in Texas since 2010, when it opened the Fort Worth office. Walker, who joined the firm in Fort Worth in 2013, launched the Dallas office the next year.

Cole Schotz has more than 135 lawyers in offices in New Jersey, New York, Delaware, Maryland, Florida and Texas.
