Few court hearings require so much bubblewrap. Lawyers for famed glass artist Dale Chihuly brought two dozen undulating, colorful and extremely fragile pieces into U.S. District Court as they persuaded a judge not to dismiss a copyright infringement lawsuit brought against two glass artists accused of selling knockoffs.

“You can’t imagine how nervous I am about handling these things,” Chihuly lawyer O. Yale Lewis said Thursday about the pieces, which were spread across his table, the courtroom floor and a bench. “I’m not touching them.”
