We shared that a patent for technology that would prevent a console from playing used games was filed back in December by Sony yesterday.  Despite the fact that this is just an application and not actually being putting to use, GameStop’s shares took a 6.1 percent fall following the news.

This isn’t the first time that GameStop’s stocks have fall due to rumors of technology that would basically eliminate the ability for a console to play used titles. Back in 2005, GameStop’s stocks dropped when rumors of the technology being used for the PlayStation 3 had emerged. Even recent rumors of Microsoft considering a similar technology for their next console had a negative effect on the company’s stocks.
