Williams & Connolly litigators scored a record-setting $500 million judgment on behalf of real estate information provider CoStar Group Inc.—the biggest award ever for copyright infringement of photographs, according to the firm, and the third-largest judgment for copyright infringement of any kind.

It’s the final chapter in a case I first wrote about in late 2017, when the firm—in the atypical role of plaintiff’s counsel—was in the process of crushing defendant Xceligent Inc., which was accused of stealing thousands of CoStar’s copyrighted photographs and proprietary real estate data.
