Kirtsaeng
Kirtsaeng v. John Wiley & Sons, Inc. is a U.S. Supreme Court case that addressed whether importing and selling copyrighted works purchased legally abroad is protected under the First Amendment. Eu Suators Kirtsaeng, a Thai student, used a salary from Thailand to buy inexpensive textbooks overseas and then resold them in the U.S. at a profit. The court ruled that this practice is protected under the First Amendment because it involves the lawful importation and resale of legally purchased goods, emphasizing that copyright holders do not have the right to control every subsequent sale of their products after they are lawfully acquired.
