The first example above shows a mark owned by Major League Baseball. As you would expect, all professional and college team logos are clearly protected by trademark. But the legal protection extends well beyond the team name and logos themselves. If a design shows a combination of elements that clearly indicate a particular team, then that design is considered infringing as well. For example, if a shirt that includes a baseball image, a reference to Boston and the colors used by the Red Sox team, the trademark owner would very likely have a claim for infringement.
