CareFirst is the Maryland affiliate of BlueCross BlueShield.  Its press release states that a decision by a federal judge regarding reforms pressed upon CareFirst by Maryland’s Insurance Commissioner “ensures its continued use of the trusted Blues trademark.”  The national BlueCross BlueShields organization had suspended CareFirst’s affiliation and ability to use the BlueCross BlueShield mark, arguing, according to this article, that the state-imposed requirements had created a state-takeover that in effect that violated its trademark agreement with CareFirst.
