WASHINGTON (AP) — The Supreme Court ruled Tuesday that textbooks and other goods made and sold abroad can be re-sold online and in discount stores without violating U.S. copyright law. The outcome was a huge relief to eBay, Costco and other businesses that trade in products made outside the U.S.

In a 6-3 opinion, the court threw out a copyright infringement award to publisher John Wiley & Sons against Thai graduate student Supap Kirtsaeng, who used eBay to resell copies of the publisher’s copyrighted books that his relatives first bought abroad at cut-rate prices.
