I would have to ask for clarification here. Which actions are you saying are exclusive? Trademark infringement/false designation of origin and failure to attribute under VARA apply to different things, in the sense that trademark law and copyright law apply to different things. But I’m not sure exactly what you’re trying to say here.
Trademark law only preserves the exclusive use of the logo as a trademark. It can’t be used to prevent copying of a public domain work. Yes, that can result in some complicated situations in specific cases, but conceptually, it isn’t difficult at all.
This is what Landau says (granted, I haven’t yet had the time to read this article thoroughly):
On its fact, this sentence looks wrong to me. It should be a violation of Section 43(a) only if the image of Mickey Mouse is used in a way that misleads the consumer with regard to the origin of goods or services. In other words, a use in commerce under trademark law.
I think you missed the point of Chronos’s post. It is about this very distinction.
This is not an analogous situation. Every drug approved by the F.D.A. has a generic name. Viagra is sildenafil citrate and Cialis is tadalifil. Generic drug makers are able to market the exact same goods without encountering the trademark problem. And the name of a drug is not as inherent to the making of a drug as names like “Superman” are inherent to names of characters and other elements of creative works.
This is exactly the complication that we have discussed in this thread and other similar threads. I don’t think it’s as simple as you lay it out. The Conan Doyle Estate holds at least two registered trademarks on “Sherlock Holmes” and likely has claims on numerous unregistered trademarks. That doesn’t stop Leslie Klinger from selling books that say “Sherlock Holmes” right on the cover, to indicate that the contents are stories that feature the public domain character Sherlock Holmes.
It seems to me that you are quite aware that U.S. courts are unlikely to interpret the intersection of copyright and trademark law in this very silly manner.
Trademarks are potentially without any limit on their term of use, but they are not statutorily unassailable now. Even valid trademarks are limited in scope. And it seems to me very likely that when a Superman story enters the public domain, that anyone publishing that story will have some kind of right to label it with the name “Superman.”
The specific border that demarcates the separation between Warner Bros.’ trademark right in “Superman” and the right of a publisher of a public domain Superman story to truthfully label it as such will have to be negotiated, but I have no doubt that the courts will not require essential portions of a public domain version of Action Comics No. 1 to be whited out.
