In today's Internet-based and global business environment, the legal issues companies face will often involve issues of intellectual property. Virtually every product people purchase is protected by a trademark, a patent, and/or copyrights. Thus, basic concepts of intellectual property are a natural component in any business law or legal environment course. Case studies are often used in business law classes, utilizing real or hypothetical fact patterns to help students identify and analyze real business problems. One can find numerous case studies for use in the classroom involving intellectual property issues. Students are already very familiar with the iPhone and Apple, Inc. (Apple), so the legal concepts are likely to resonate with them. This case is designed to expose students to the Lanham Act, U.S. Patent & Trademark Office (USPTO), and the registration system in the United States, while also demonstrating the global issues involving trademark registration and infringement. This article presents a scenario that demonstrates how a product name, or trademark, can become a major issue for companies. Part II.A of this case study presents the facts of the dispute, and Part II.B contains questions for discussion, both of which could be distributed to students in a classroom setting. Part III contains a Teaching Note with background information in basic trademark law concepts and guidance to use the case in a business law or business ethics class. (Contains 133 footnotes.)
