Amazon Poised to Sell Used E-books

Amazon’s business model has long been dependent on resellers of used books and other merchandise. But a U.S. patent that Amazon Technologies in Reno, Nev., received last week indicates that the mega-retailer has its sights on digital resale, including used e-books and audio downloads. According to the abstract, Amazon will be able to create a secondary market for used digital objects purchased from an original vendor by a user and stored in a user’s personalized data store.
