Marketplace Policy on Copyright and Trademark-Protected Content

Hey there - I followed up with your pack and it was accidentally marked as a duplicate due to its name being similar to another pack you submitted. The team is fast-tracking your asset and it’ll be going into review shortly. Apologies for the mix-up there!

Hi Amanda, can you please tell somebody to also look up #98945 ?

We’ve done the required change 1 week ago and it basically only needs someone to allow us to publish but nobody answers in the email.

It’s still in final review, but should be completed within the estimated time you were given.

Thank you very much.
So it was a mistake? Will the promised 10-15 working days be met now?
That was my fifth plugin and I always had to wait about 2 months.

Happy to help! Barring any unforeseen circumstances, your asset should be ready in 10-15 days.

Hello, me again. :slight_smile:
I’m confused right now. I’m programming a new code plugin. I want to use a part of the C++ code from the AudioRecorder plugin. I have sent an email to support and I’m not allowed to use anything from Epics plugins.

Why not? Do the plugins have a different license?

How much of that code is replicated in your code? That code is as free as the engine. The logic 1st applied is that you cannot generate a version of the engine or its components and resell. So, it all depends on “how similar” that part of code is, basically a code is not copyrighted unless that part of the code belongs to a specific algorithm (unless it is yours), technique (unless it is yours) or way that will only work on the engine.

Lets say I want to redesign the Renderer module and make it better. That Renderer, besides it can be switched in the engine code, it so tighly attached to it, that it will not work without the rest of the engine, and probably will not work in other engine aswell, so by design, even if it is better, you cannot sell it, because the intrinsic dependencies. You can thou, have it as part of your own custom engine version (4.18.2.Socke81) and create a game and sell this game, but you can’t come up with this piece of code and try to sell for the engine users, because the dependency makes it not belong to you.

Im sorry if Im not well enough in english to explain this, but I hope I could achieve it.

  1. Epics AudioCapture plugin can record audio and convert it to UE4 specific audio formats and .wav format. I am working on an voip/voice chat plugin. I want to use few parts in my own code. Not a exact copy but parts to get data from mic and maybe to convert it to a sound cue or wav.

  2. Epics AudioCapture plugin uses a thirdparty library. This:
    The RtAudio Home Page

I asked the support whether I could use this library too. And is this still Third party? It is a part of UE4.
I was told not to use anything. That’s why I asked here. This can’t be right. Why shouldn’t that be allowed?

I have checked the page and you can use it “if” you follow these instructions at the License page:

check that you MUST put the copyright notice somewhere with your product source folders and also put it on the files where you use the library code, including the link as Epic did. It is also a good procedure, to create a document with the link and its content, the use you will give to it also, to be autenticated at (notary’s office - register) that the link at the date of the authentication had the exactly text above. It is your safeguard because that content might change and you need proof you are legal.

Hi all,
I wanted to make sure everyone saw that we’ll be having a livestream today to talk about copyright and trademark laws. You can find the details here.


Well, in most cases these aren’t actually copyrights in question.
The rights that may be involved here are either design patent rights or the so-called “trade dress” rights.

  1. The design patent rights actually grant the owner copyright-like powers over ornamental (e.g those not dictated by the item’s function or constuction) features of the design (this may be the whole external look of the issue, if not dicated solely by technical considerations). These rights however, last AFAIK 15 years in USA and up to 25 years elsewhere (the laws differ from one country to another). So things designed before 31.12.1992, or 31.12.2002 for the US are most likely free from design patent rights.

  2. The trade dress issue is a bit trickier. The “trade dress” is actually a trademark right, granting the owner trademark powers over ornamental (e.g those not dictated by the item’s function or constuction) features of the design (this may be the whole external look of the issue, if not dicated solely by technical considerations).
    Becaus it is a trademark right, “trade dress” could be registered in only one country, or it several, or variably across the globe.

Here ( ) it is possible to consult the register (not all countries are covered, but international trademark applications as well as US, EU, Canadian, German, and some other trademarks are.
If a particular design is not registered as a trade dress, things actually get much easier - unregistered trademarks are granted far less protections if any at all (depends on the jurisdiction in question, really).

As the “trade dress” are trademarks, they are protected only if a) the have the capacity to indicate a source of origin for goods, b) they are used in commerce and not abandoned. From there arise several considerations.

  1. If an unregistered trade dress have become generic (this means the desing is used in commerce by several different firms, each marketing the design under their own trademarked names for significant time) it is not protected and more still, no-one particular would be there to complain alleged misuse.
    Considering the question of firearms design (they, as I heard, caused most questions here) this means that designs like M1911, or generic pump-action shotgun, or generic lever-action Henry rifle are free to be exploited by members
  2. If an unregistered trade dress is not used in commerce by the owner (item get out of production) it is not protected. For practical considerations the designs originating with the now-defunct manufacturers or those out of production for a decade or more are most likely free to exploit.

Also, some specific cases you might find somewhat interesting

  1. The M16 rifle. Associated trademark and trade dress ( ) invalidated and declared generic. With the patents on it also expired by the virtue of time passed - no restrictions would apply on using the design.
    PS: Colt, FN, Colt’s and FN’s logos and brand markings remain trademarked
  2. The M4 carbine. Associated trademark and trade dress ( ) invalidated and declared generic. With the patents on it also expired by the virtue of time passed - no restrictions would apply on using the design.
    PS: Colt, FN, Colt’s and FN’s logos and brand markings remain trademarked
  3. MP5 SMG. Trademark applications ( , DPMAregister | Trade marks - Register information ) refused on grounds of the design being functional or aesthetically functional.
    PS: H&K, their logo and brand markings remain trademarked
  4. XM8 rifle. Trademark application abandoned ( ) more than 10 years ago.
    PS: H&K, their logo and brand markings remain trademarked
  5. Beretta 92FS (M9) pistol. Trademark application abandoned (** ) more than 20 years ago.**
    PS: Pietro Beretta firm, their logo and brand markings remain trademarked

Hi! I’m a Bologna Business School’s student and we are doing a project on virtual reality world.we ask you only few minutes to fill in our questionnaire in this link. Thank you so much!

Quick question, let’s say I’m adding the default third person UE4 Mannequin to an example level in my marketplace asset, do I need to remove the logo on his chest?

What are the marketplace limitations on text in a quiz game? Are they considering quiz questions on Copyrighted works Restricted content? A quiz style game with questions in text form about a movie, TV Show or let say a quiz game template created blueprints containing 100 questions on video games like “Fortnite” etc… Generally trivia games that ask factual questions in text about all kinds of subjects are considered fair use.

I would love to see ray-tracing CGI of Steven Spielberg’s Animaniacs in next year of Unreal Engine 4 technological improvements. I mean fanbase of Animaniacs equivalent with Disney/Lucas Film Star Wars imagine also 4K cutscenes of fanmade cutscenes in Mantinee Mode(equivalent to Source Film Maker). Speaking of Unreal Engine 4 GDC 2020. How unfortunate that creators of Ratchet and Clank live-action movie Rainmaker Studios cancelled Popeye live-action movie with cartoon 3d aesthetics kind of like that happened with some TMNT cartoons, Inspector Gadget, Garfield, Alvin and the Chipmunks. Sweet and lovely nostalgia. Also Warner Bros will be involved in Flintstones tv cartoon reboot. Wonderful news, right? Do you think Sonic the Hedgehog live-action movie fan service is better than generic film kind of like fan edited live-action movie of Disney’s The Lion King. Let’s forget about Jazz Jackrabbit(because it’s not popular so it’s waste of Epic Games/Tencent money so nobody cares you are doing whatever you want) and never mention it again in this forum. Because I’m just frustrating you guys. I don’t want to be jerk anymore. Once again so sorry for my chaotic speech of sentences. Let’s back to topic shall we? If someone is 3d modelling, rigging and animating expert(not me) then how long have to wait for permission to distribute assets in Unreal marketplace?

About creative commons atribuition (Creative Commons — Attribution 4.0 International — CC BY 4.0) it says I’m free to use commercialy if I adapt, being only necessary to give appropriate credit. Is it good to use those kind of 3D assets in my marketplace plugin or could happen any problems from it?

My opinion regarding this falls under the following statement (Under the Following Terms):
No additional restrictions — You may not apply legal terms or technological measures that legally restrict others from doing anything the license permits.

This particularly means that your work could also to be adapted and used commercially, since you can’t change the behavior the license has, but perpetuate it along your products. This is my understanding, I might be wrong. Is this really what you want to? How do you plan to make noticeable the attribution to the original work and the changes you promoted? Seems too much job to me and high risk.

I see, so its possible to be interpretated as my whole work also becoming Creative Commons, yeah thats definetly not what I want. Thanks for the help!
