Not too long ago, ZeniMax Media, the parent company to Bethesda, filed for a trademark of the name "Redfall." While its official purpose has not been confirmed to any degree, fans quickly speculated that this would be the title of the next Elder Scrolls game, which was announced last E3.
As it turns out, Redfall is the name for a series of science fiction novels written by Jay Falconer and published by Bookbreeze. Expectedly, Bookbrooze contested the filing.
While we don't know the details, the two companies appear to have come to an agreement that both of them are happy with. Falconer himself announced on Facebook the official conclusion:
"Dispute Over 'Redfall' Trademark Settled
ZeniMax Media Inc. and Bookbreeze.com are pleased to announce that they have amicably resolved a pending trademark dispute related to the Redfall trademark. While the specific terms of the agreement are confidential, the parties believe that resolution of the matter is mutually beneficial to both ZeniMax and Bookbreeze.com and their respective fans."
In truth, we have no idea what kind of conclusion they came to in the end. It's possible that after discussing their intentions, Bookbreeze believed that there wouldn't be any overlap risk with ZeniMax's product. Maybe they agreed on some kind of cross-promotion. It's all up in the air right now.
We don't even know that Redfall will be an Elder Scrolls title. Bethesda has a multitude of franchises in their pocket, ZeniMax even more so. The only reason people think it's an Elder Scrolls name is because of how closely it sounds to Redguard, one of the races in the game.
Whatever Redfall is, it sounds like ZeniMax will have the freedom to use it as they need. Now we can only wait and see what it is.
