Let's say X develops an app that tracks injuries of players who play in the NFL...


  1. Can X legally name the app NFL Injury Tracker? (...without infringing on any trademarks, etc.?)

  2. What restrictions would there be on X's use of the NFL logo in the app's marketing materials?

  3. What if X uses a logo slightly resembling the NFL logo but is not the same as the NFL logo?

NFL Logo

Possible app logo (to be adapted)

The NFL can prohibit X from using its trademarks, or markings that would be likely to confuse a reasonable person, in any of X's business marketing.

The NFL's shield wordmark has USPTO registration number 4682232 (deep links aren't allowed, but their search engine is here.) The images you've added don't seem alike enough to be confusing to me (I don't think I'd be mistaking one for the other), but in a lot of settings the app name will have only text, not an image. Then you get at the trademark issue for the term "NFL" itself.

NFL can trademark that three-letter sequence, and there are good reasons for them being able to keep control of that trademark to authenticate sourcing. For example, if I said "this hamburger is from McDonalds" you have certain expectations about it based on the brand, and McDonalds the company has a legally protected interest in preventing me from saying that if it wasn't true. I have no right to put that 9-letter sequence on my burger joint without a license from the corporate giant.

Similarly, The NFL has a legally protected interest in preventing somebody from advertising or implying that an information source or the information contained therein is licensed and/or an official source of information, if that's not true. A reasonable person might expect that an information source about NFL player injuries, with "NFL" in its name, would be an official licensed source of that information; the real NFL can seek an injunction and/or penalties if that's not actually the case. "Pro Football Player Injury Tracker" might not carry the same expectation.

At the bottom of NFL.com, they claim, emphasis added, that "NFL and the NFL shield design are registered trademarks of the National Football League." So they have put folks on notice they intend to defend that three-letter sequence as theirs, at least for all subjects related to professional American football.

Sean Mullin says "The NFL is notorious for guarding its intellectual property rights to the full extent of the law." X should probably spend some time with an IP lawyer.

If you're asking if it's possible for X to legally use the NFL's trademark, the short answer is yes. It is possible for X to license use of the trademark from the NFL so long as the NFL is willing to grant/sell the license on terms that X also agrees to.

See this prequalification page linked to from this law firm's website, or click "Become a Licensee" here to see that in context.

  • Still seeking more answers. This answer does not address all the subtleties of the question. For example, in this scenario: 1. X does not seek to use the NFL logo. But the acronym NFL is in the title. Surely, the three letters in sequence: N, F and L can not be protected? Can it? 2. The real NFL logo might be this. And the app might adapt a logo that looks more like this. Would that be a problem? What trademark law principles are in play here? Commented Sep 7, 2015 at 19:22

    Answer edited. In short: 1. Yes it can. 2. Consider editing your question to put those images in; you can use <img src="imageURL" /> tags or the GUI editor to put in images.

It seems to me that NFL Injury Tracker might fall under the same use as the Playboy case.

The Court held that nominative use (a type of fair use for discussing the product itself) is permitted where:

The product or service can not be readily identified without using the trademark (i.e. trademark is descriptive of a person, place, or product attribute);

Only so much of the mark may be used as is reasonably necessary for identification (e.g. the words may be reasonably used but not the specific font or logo); and

The user does nothing to suggest sponsorship or endorsement by the trademark holder - which applies even if the nominative use is commercial.

Here, the Ninth Circuit Court applied the nominative fair use test to the defendant and concluded the Defendant’s use of these trademarked items was permissible because there was no other practical way for the Defendant to describe herself.

If someone is tracking injuries in the NFL, I hope a court would find that there is no other practical way to describe the data source than to refer to the NFL. I would think that they should not use the logo at all as this fails the "only so much of the mark may be used" test.

As for number three, confusion was addressed by another answer.

  • Would a phrase like "Pro football" in place of "NFL" communicate the same thing to most of the audience without using the trademark?

  • No because there is more than one professional football league.

  • Any nearly as popular as NFL, in the US? Also, might this lead X to expand their market?

  • I don't know enough about football leagues, there is probably a football stack where you could ask!
