Final answer:
Michael Jordan's lawsuit against Jewel Food Stores was for unlawful use of his likeness, not copyright infringement. The case revolves around the protection of personal brand and image rights.
Step-by-step explanation:
Michael Jordan sued Jewel Food Stores over unlawful use of his likeness. This type of legal action is centered around the protection of a person's image and personal brand. Jewel Food Stores used Jordan's persona in an ad without his permission, and as such, this could damage his personal brand's value and earned him the right to take legal action. This is different from copyright infringement, which deals with the unauthorized use of copyrighted material. An example of a copyright infringement case would be the lawsuit where Marvin Gaye's family was awarded over 5 million dollars from singers Pharrell Williams and Robin Thicke for plagiarizing one of Marvin Gaye's songs.
