Supap Kirtsaeng, a citizen of Thailand, was a graduate student at the University of Southern California. He enlisted friends and family in Thailand to buy copies of textbooks there and ship them to him in the United States. Kirtsaeng resold the textbooks on eBay, where he eventually made about $100,000. John Wiley & Sons, Inc., had printed some of those text-books in Asia. Wiley sued Kirtsaeng in a federal district court for copyright infringement. Kirtsaeng argued that Section 109(a) of the Copyright Act allows the first purchaser-owner of a book to sell it without the copyright owner's permission. The case ultimately reached the United States Supreme Court, which ruled in Kirtsaeng's favor. The first sale doctrine applies even to goods purchased abroad and resold in the United States.

Note: Can you please answer this question using IRAC( Issue, Rule of Law, Analysis, and Conclusion) format. Because then it will be easy for me to understand the case a a lot better.
