tl;dr: We have to change the title of our game Dieselstörmers due to an objection to our trademark registration by fashion label Diesel. Below you can read the full text of our announcement.

a year ago, indie dev Black Forest tried to register a European trademark for the roguelike coop run’n’gun game DieselStörmers. This was opposed by fashion label Diesel, who hold a broad trademark for the word “Diesel” that seemingly also covers videogames. The Office For Harmonization in the Internal Market ultimately accepted Diesel’s reasoning and denied the registration of Black Forest Games’ IP, even though the “Diesel” in DieselStörmers refers to the fuel of the same name, not to fashion or clothes.

This decision has quite an impact on BFG. After all DieselStörmers, which was funded through Kickstarter and released to Steam Early Access in July 2014, saw good progress with multiple updates since its initial release – the latest one on September 11th. The game was well on its way for its final release.

Black Forest’s Managing Director Adrian Goersch comments: “ This decision has caught us with our pants down. We are quite surprised that our trademark application has been formally denied. We are no multinational corporation, we cannot fight this decision, even though, frankly, it is a disaster with indie marketing as difficult as it is today. But the history of this game and our company as a whole has been marked with tough challenges and we will manage to overcome this one as well. First of all, we will make sure everyone will be able to keep playing the game, then will come back with a new name.“

Good heavens. Trademark has gone just as nuts as copyright.

Haha, yeah, and after that, the fuel comanies will have to rethink their product names…

And now? Rename it back to “Ravensdale”?

Nope. It was a deliberate decision to change the name to Dieselstörmers.

Well. Let’s call it “WeaselStörmers (formerly known as DieselStörmers)” – They can’t argue on that one, can they? 🙂

Keep your heads up, folks!

Black Forest Games Team

Thanks! 🙂

I’ll never buy Diesel fashion anymore!!!

You should rename it to FuelÖilStörmers just for spite.
Or if you want to use more grammatically correct umlauts in the name, call it LöpöStörmers
(löpö is commonly used name for fuel oil in Finland).

Shouldn’t have caved. You could have easily brushed this off with a quick talk with your lawyer and an appeal. No one in their right mind would think “DieselStörmers” was connected to a shitty jeans company.
Stupid effing companies think they can get away with bullying like this because the little guy doesn’t know he’s in the right.

How can you trademark the word “Diesel”? That’s just rediculous. Is “Octane” and “Gas” trademarked as well? So if I develop a software for, I don’t know, let’s just say cars running on Diesel, I’m not allowed to put “Diesel” in the name of the software? Sounds like American lawcourt, where you can sue anyone for anything. Or did I just get something wrong?

Also: hooray for no pants! Home is where the pants aren’t!

Just imagine they would start trademarking everyday words like pear or … oh, never mind.

Put an umlaut over the “e”.

Why don’t you keep the name? Do you absolutely need a trademark? At this point I think changing the name again might do more harm than just not having a trademark.

Just call it CandyStormer Saga already

You could mark the part of the name with “Diesel” as an invalide document. So every one does see the name is invalide and you are actualy only using “störmers “.

Some Norwegian Bastard

Does this mean all petrol stations must cease and desist advertising for “diesel”?
Seriously, this is bullshit and they don’t own the use of the word “diesel” for anything but the sales of clothing.

[…] Dieselstörmers is no more – not its title, anyway, as developer Black Forest Games has lost a legal battle with fashion label Diesel, as announced on the project’s Kickstarter page (and further detailed in a developer blog post). […]
