Ahem, huh? Well this is… strange. Around September of this year, Microsoft submitted an application to the U.S. Patent and Trademark Office (USPTO), setting off a flurry on speculation of whether a new Killer Instinct game was being made if a re-release of the previous two KI games on XBLA was possible. Unfortunately looks like those plans might be stifled a bit as, according to Eurogamer, the USPTO denied Microsoft’s application due to someone else having it. Fox currently owns the trademark, which they used for the shortlived slogfest of a crime drama called… Killer Instinct.
