Copyright protection of Unauthorized Graffiti
A number of comments and some other answers have raised the question of whether graffiti made without the permission of the owner or tenant of the location, and therefore illegally, are entitled to copyright protection.
The first thing to say is that there is nothing in 17 USC (the US copyright law) that conditions copyright protection on the legality of the work, or of its publication.
Case law on this precise issue is not easy to find, nor does there seem to be much of it.
IPWatchDog's "Preventing a Graffiti Copyright Infringement Lawsuit" (2018) says:
Several high-profile companies, American Apparel, Coach, American Eagle Outfitters and H&M who shot advertisements in public spaces, have found themselves inadvertently in the midst of such legal disputes with street artists. Even though an advertiser may have had permission from the property owners, even though the “artwork” was unsanctioned and unsigned or “tagged,” the graffiti artists have come forward after the ads were already in circulation, identified themselves and sought compensation and damages.
It goes on to say that:
These cases tend to be settled out of court, because regardless of the merit of an infringement claim, they are costly to defend and the unwarranted negative publicity can injure a company’s reputation. ... Also, from a legal standpoint, the question of whether the copyrights of illegally created street art are valid has not yet been determined – so there would be some element of doubt as to how a litigation would be decided.
*The Atlantic's article "Can Graffiti Be Copyrighted?" about the case of graffiti artist David Anasagasti's case against American Eagle Outfitters for use of his work (and several other similar suits) quotes Philippa Loengard, assistant director of Columbia Law School’s Kernochan Center for Law, Media, and the Arts as saying:
Given what I know of the case, this is one of the most blatant examples of copyright infringement
None of the suits mentioned in the story seem to have resulted in a court decision as yet.
In Falkner v. General Motors Company, the trial judge held that the art was not "part of" the building and thus the exemption for photos of architectural works under 17 USC 120 does not apply. However it denied plaintiff’s DMCA claim and his claim for punitive damages.
The court held that:
because the facts in the record tend to establish—if anything—the lack of a relevant connection between the mural and the parking garage, the Court cannot hold as a matter of law that the mural is part of an architectural work under Section 102(a)(8). Thus, it cannot reach the issue of whether Section 120(a) applies to the mural to permit photographs of the mural.
In an article in the N.Y.U. Journal of IP & Entertainment Law "Protecting Artistic Vandalism" author Celia Lerman argues that copyright should protect unauthorized, illegal graffiti art.
This article notes that:
Graffiti pieces increasingly attract the attention of numerous collectors, gallery owners, publishers, filmmakers, and journalists. Pieces from famous graffiti artists have sold for hundreds of thousands of dollars in the art market. Graffiti pieces have even been given as diplomatic gifts. Galleries are seeing record attendance at exhibitions of graffiti works, and publishers have generated a boom of photographic books on graffiti and street art. (citations omitted)
The article notes that Tattooed Walls a book by Peter Rosenstein about NYC Graffiti, reproduced images of many works of graffiti without permisison, the author believed that these were fair use because they were posted in public places. Several artist sued, a settlement was agreed to, and the book was withdrawn from publication.
The article mentions a suit against Tony Hawk’s Pro Skater 2 Official Strategy Guide, by the author of a work of graffiti which was reproduced. The suit was initially dismissed for lack of copyright registration, but the court said that it “assumed, without deciding, that the work is copyrightable.” When the suit was refiled after registration, a motion to dismiss was denied, and the parties then settled, so there was no court decision on the merits.
Other simialtr cases are mentioned. The article goes on to analyze the law and the purposes that copyright law serves, and give reasons why such works should be protected. But none of this cites an actual case where an illegal graffito has been held protected.
The Falkner case will not produce such a ruling, because the art in that case was authorized, indeed invited, by the building owner.
