American Airlines filed suit against the United States Copyright Office last Friday, following its denial to register American Airlines’ new logo. American Airlines Group, Inc. (NASDAQ: AAL) filed for the registration five years ago, following its merger with US Airways. The new logo consisted of a blue and red diagonal stripe, with an eagles head in the middle.

The Copyright Office denied the Airlines request, stating that “While the bar for creativity is low, it does exist, and the work cannot glide over even its low heights.” The airline strongly disagrees with that statement, leading to its decision to move forward with this lawsuit.
