The NFL's Washington Redskins may be strong-armed into changing their name.  The U.S. Patent Office has canceled six trademarks that the team has, ruling that the term "Redskins" is "disparaging" to American Indians.  The team will appeal, and can continue to hold the trademarks in the meantime.

Even if the Redskins lose on appeal, the team can continue to use the name, as it has for more than 80 years.  But without federal trademark protection, others could potentially use the name and logos, to sell merchandise and stuff like that.

Last year, Redskins owner Daniel Snyder said he would "never" drop the team's name.
