Patently-O commentator Mark Bartholomew points to this Federal Circuit case. The issue is when a trademark may be denied for containing “matter which may disparage” a group of persons. At issue in this case is a proposed mark of STOP THE ISLAMISATION OF AMERICA which was denied for violation of this disparagement provision. The Federal Circuit approved a two-prong test. Bartholomew further states:

• “Under the first prong of that test, a court must determine the likely meaning of the mark in question. Under the test’s second prong, the court examines whether the likely meaning refers to an identifiable group and, if so, whether that meaning is disparaging to a substantial composite of that group.”
• “The stakes are high here because the Federal Circuit is the typical route for appeals of [Trademark Trial and Appeal Board] decisions, and a highly anticipated decision from the TTAB on disparagement involving the WASHINGTON REDSKINS mark is due soon.”

There ought to be little doubt that the term “Redskins” refers to an identifiable group – i.e., American Indians.  As to the issue of disparagement, the Federal Circuit has endorsed a rather permissive evidentiary standard, which allowed for consideration of anonymous blog posts to show public perception and reaction to a proposed mark, and statements from members of the disparaged group stating concern over such disparagement.  One key issue that the Court did not address is what constitutes a “substantial composite” of the referenced group.
