A very dramatic patent application put forth today by Sony has resulted in a significant drop in GameStop shares.
The patent is for a new piece of technology which will make it impossible for used games to be played on the console, and since GameStop thrives off of used game sales, it could devastate their sales.
Even though Sony is putting forth this patent application, which is farther than we though they would take the idea, it seems unlikely that they would go through with adding it to the PS4.
According to Analysts, and even just common sense, it is obvious that taking away the ability to play used games would hurt Sony and put their console at a major disadvantage.
Today, GameStop closed at about a 5% share price drop overall, mainly as a result of the new patent application.
