This development indicates that Apple may probably be looking forward to create its own marketplace or a lending library for “used” digital content. Both patents describe how and where a user can transfer digital content to another one, in the same way Amazon’s third party marketplace for second hand physical goods works.
There are controversies about these patents, as they may end up affecting the full price sales of “new” digital content. But after the “first sale doctrine” established in 1908 by the Supreme Court of the United States, which rules that a copyright owner doesn’t have control over what happens to an item after the initial sale, the detractors of the idea may not have a choice but to conform.
The main objection at the moment is that if the original creators of digital content will benefit from the resale of their work. Apple’s patent suggests that it plans to do it, in order to create incentives for creators in the future.
