Curious coffee break news from top U.S. financial publication, BusinessWeek, yesterday. They reported that Starbucks may owe money to Mexico for using Aztec images on coffee mugs.

An article on BusinessWeek.com said the Mexican government has notified Starbucks Corp. that intellectual property rights for the images of the Aztec calendar stone and the Pyramid of the Moon from the pre-Aztec ruins of Teotihuacan, near Mexico City, belong to Mexico.

The report said Starbucks is working with Mexico to resolve the issue and the mugs have been removed from shelves pending the discussions.
