An anonymous reader writes "We recently discussed what appeared to be a positive response from the Obama administration on the legality of cell phone unlocking. Unfortunately, the Obama administration may not be able to do anything about it. It has already signed away our rights under a trade agreement with South Korea. Lawyer Jonathan Band, who works for the Association of Research Libraries, wrote, 'The White House position, however, may be inconsistent with the U.S. proposal in the Trans-Pacific Partnership Agreement (TPP) and existing obligations in the Korea-U.S. Free Trade Agreement (KORUS) and other free trade agreements to which the United States is a party. This demonstrates the danger of including in international agreements rigid provisions that do not accommodate technological development.'You can read more about this issue in a short eight page legal primer by Jonathan Band (PDF). An interesting, related note that the U.S.-KOREA FTA is possibly inconsistent with our domestic patent/drug law in the Hatch-Waxman Act as well. The trade agreement requires us to grant injunctions until the patent is invalidated as opposed to thirty months under current domestic law."
