In mid-September 2015, Jean was hired as a technical expert in a patent case.
It was at the Federal District Court in Marshall, Texas.
One of the witnesses was Vint Cerf, one of the two inventors (really!) of the Internet.
Dr. Cerf only flew in for two days. Jean was there for two weeks.
Some people had thought Jean was Dr. Cerf, and asked him for an autograph.
When he arrived, Dr. Cerf thought that was really funny.
One of the lawyers took this photograph.
