For the first time in an Eastern District of Texas courtroom, jurors in a patent trial recently got to ask questions of witnesses.

It was an experiment that Chief U.S. District Judge Leonard Davis long had wanted to try in complicated patent litigation — the type of case for which his jurisdiction is famous. Davis says he got the idea a year ago at a conference of chief U.S. district judges. He figured it was OK as long as letting jurors submit written questions for witnesses didn’t delay or complicate a patent trial.
