When Warner Bros. snapped up ailing publisher/developer Midway, it bought most, but not all of the company's assets, including intellectual properties like Mortal Kombat and This Is Vegas. What else did Warner Bros. grab in the Midway closeout? Lots.
While we were well aware that the WB would secure popular franchises like Joust and Spy Hunter, the currently changing trademark ownership of some classic Midway IP give us insight into what the new home of Mortal Kombat also secured. Some of it is positively ancient, like the Super Sprint spin off Badlands, and the classic Sinistar and Defender.
Trademark snooper superannuation dug up some of the trademarks transferred to Warner Bros. thus far, a list expected to expand as time goes on and the US Patent and Trademark Office gets around to it.
Missing from the list right now is Mortal Kombat, actually, which should show up as a WB property any day now—even though This Is Vegas is there.
For a very short list of what Warner Bros. didn't pick up, see this post.
