When the Federal Circuit visited Denver this past October, I attended one of the seminars where Judges Rader, Linn, and Wallach spoke. They noted that the Federal Circuit, relative to some other circuit courts, is considered to be a very collegial court.
The proceedings prior to some relatively recent oral arguments highlighted this point:
Swearing-in ceremony for Judge Prost’s clerks and remarks by Judge Moore: [Listen];
Judge O’Malley’s first panel as presiding member and remarks by Judge Plager: [Listen]; and
Swearing-in ceremony for Judge Plager’s clerk: [Listen].
