Here it is — Betty Boop's first appearance, which became public domain on Thursday. It's a 60-second song halfway through a longer cartoon about a restaurant titled Dizzy Dishes. (The first scene makes it clear this is a restaurant of anthropomorphized animals — which explains why the as-yet-unnamed character has floppy dog ears...)
So Fleischer Studios has now warned that claiming Betty Boop is public domain "is actually not true."
Very often, different versions of a character that have been developed later can independently enjoy copyright protection. Also, names and depictions of a character very frequently will remain separately protected by trademark and other laws, regardless of whether the copyright has expired.
But is that really true? Fleischer Studios went out of business in 1946, notes Los Angeles Times columnist Michael Hiltzik:
By then it had sold the rights to its cartoons and the Betty Boop character. A new Fleischer Studios was formed in the 1970s by Fleischer descendants, including Max's grandson Mark Fleischer, and set about repurchasing the rights that had been sold. Whether it reacquired the rights to Betty Boop is up for discussion... According to a federal appeals court ruling in 2011, the answer is no. Having navigated its way through the three or four copyright transfers that followed the original rights sale, the appeals court concluded that the original Fleischer studios sold the rights to Betty Boop and the related cartoons to Paramount in 1941 but couldn't verify that the rights to the character had been sold in an unbroken chain placing them with the new studio. The "chain of title" was broken, the appellate judges found — but they didn't say who ended up with Betty Boop.
And last month Cory Doctorow pointed out that "while the Fleischer studio (where Betty Boop was created) renewed the copyright on Dizzy Dishes, there were many other shorts that entered the public domain years ago."
That means that all the aspects of Betty Boop that were developed for Dizzy Dishes are about to enter the public domain. But also, all the aspects of Betty Boop from those non-renewed shorts are already in the public domain. But some of the remaining aspects of Betty Boop's character design — those developed in subsequent shorts that were also renewed — are also in the public domain, because they aren't copyrightable in the first place, because they're "generic," or "trivial," constitute "minuscule variations," or be so standard or indispensable as to be a "scène à faire...." But we're not done yet! Just because some later aspects of the Betty Boop character design are still in copyright, it doesn't follow that you aren't allowed to use them! U.S. Copyright law has a broad set "limitations and exceptions," including fair use.
So while Fleischer Studios insists Betty Boop "will continue to enjoy copyright and trademark protection for years to come," Doctorow has some thoughts on that trademark:
Even the Supreme Court has (repeatedly) upheld the principle that trademark can't be used as a backdoor to extend copyright.
That's important, because the current Betty Boop license-holders have been sending out baseless legal threats claiming that their trademarks over Betty Boop mean that she's not going into the public domain. They're not the only ones, either! This is a routine, petty scam perpetrated by marketing companies that have scooped up the (usually confused and difficult-to-verify) title to cultural icons and then gone into business extracting rent from people and businesses who want to make new works with them.
"Trademarks only prevent you from using character names and depictions in a way that misleads consumers into thinking your work is produced or sponsored by the rightsholder," Duke University clarified in their January 1st explanation of Public Domain Day 2026 — "for example, by putting them on unlicensed merchandise. They do not prevent you from using them in a new creative work clearly unaffiliated with the rights owners..."
"Regardless of who owns the later versions of the character, the original Betty Boop character from 1930 is in the public domain."
This is another reason why copyright expiration is so important: It brings clarity... Under US copyright law, anyone is free to use characters as they appeared in public domain works. If those characters recur in later works that are still under copyright, the rights only extend to the newly added material in those works, not the underlying material from the public domain works — that content remains freely available. Second, with newer versions of characters, copyright only extends to those new features that qualify for such protection...
Dozens of post-1930 Betty Boop cartoons, including Ker-Choo (1932) and Poor Cinderella (1934), did not have renewals. The newly added material in these animations is also in the public domain... To sum up the copyright story so far: in 2026, the underlying Betty Boop character goes into the public domain. She is joined there by the attributes, plot lines, and dialogue that were first introduced in those later cartoons without renewed copyrights, as well as the uncopyrightable attributes of her later instantiations...
Certainly, there would be a risk of consumer confusion if you use Betty Boop as a brand identifier on the kind of merchandise Fleischer sells — jewelry, back packs, water bottles, dolls. Trademark law does protect Fleischer against that risk. Contrast these uses with simply putting the Boop character in a new artistic work. This is exactly what copyright expiration is intended to allow. Were trademark law to prevent this, then trademark rights would be leveraged to obtain the effective equivalent of a perpetual copyright — precisely what the Supreme Court said we cannot do...
If courts have delineated the line between copyright and trademark, why is there so little clarity in this area? Sadly, companies sometimes claim to have more expansive rights than they actually do, capitalizing on fear, uncertainty, and doubt to collect royalties and licensing fees to which they are not legally entitled.
