Just came across an interesting article, from the American Indian perspective (sorry to be so PC), concerning the ongoing litigation over the Washington Redskins name. Harjo et al had persuaded three trademark judges on the substance of their grievance in 1999; in 2003, a district court overturned their finding. This article cites some detective work by Geoffrey Nunberg of Stanford on the point.
