Although Notch's ideas are diplomatic, international copyright law is rarely clear-cut enough for a 50/50 compromise. [...] This conundrum gets even more confusing, since the lawsuit will take place in Swedish courts, and U.S. copyright legality may not hold much water overseas.
Mojang's desired use of the word "scrolls" seems innocent enough, but if Bethesda does not protect its copyright, other companies could produce deliberately-confusing titles like The Eldest Scrolls: Skyrings and leave Bethesda with no legal recourse. "Failing to protect a trademark could be damaging to an owner's rights," said Angela Bozzuti, a trademark law attorney. "Not only could it result in actual consumer confusion, but it could also weaken the strength of the mark in the marketplace. Furthermore ... it will likely weaken [Bethesda's] mark and make protection difficult and limited."

Yes, but until those laws change, Bethesda doesn't really have a choice. If they don't fight this, then they can't fight the guy who makes "The Older Scrolls: Flyrim." It's not Bethesda just being ornery; the US Trademark office said that Notch's offer to add a subhead to Scrolls (i.e. Scrolls: The Something-or-Other) wasn't enough to differentiate it from The Elder Scrolls. Given that ruling, and the vagaries of copyright law, there's not a whole lot of wiggle room here.
I don't know if this has already been pointed out, because I can't go through nearly a dozen pages of comments right now, but this has
nothing to do with copyright, despite most of the posts saying so (including the original news post itself).
I don't know enough about how it works internationally to be able to say with any confidence how it works anywhere else, but at least in the US, you don't have to defend your copyright to maintain it, or even register it in the first place (although if you do register it, it does grant you additional protections and makes things easier for you in general). Copyright does not cover things like this, though; it can apply to the artwork, the music, the code, or even the game as a whole, but the title itself is strictly in trademark territory.
In the US, at least, you have to be much more aggressive about defending trademarks or risk losing them. If you don't actively use it for a certain period of time, you can lose it. If you don't defend it when someone else even
appears to possibly be infringing on it, you can sometimes be at risk of losing it. A lot of the time when it seems like someone's being a dick about lawyering up over defending trademarks, it's because of how people have lost them in the past from not doing that, especially genericized trademarks [http://en.wikipedia.org/wiki/Genericized_trademark]. Yes, someone actually managed to lose the trademarks for things like zippers and escalators and
heroin.
So yeah, nothing to do with copyright at all, and the reason they do stuff like this a lot of the time is that the legal system pretty much requires them to.
