Universal City Studios filed for "Demented Circus" on Nov. 3, and the filing covers everything from escape rooms to stilt walkers. Universal hasn't said what it's for.
Universal wants the name "Demented Circus," and it wants it for theme parks.
Universal City Studios LLC filed a trademark application for DEMENTED CIRCUS on Nov. 3, 2026, according to the U.S. Patent and Trademark Office. WDWNT spotted it Sunday, Nov. 8. The application is serial No. 50197939, and it's still waiting for an examining attorney.
It's filed as an intent-to-use application. That means Universal hasn't used the name yet but says it plans to. It's a plain-text mark with no logo, font or color claimed.
Universal hasn't announced anything called Demented Circus. Everything below about where it could land is speculation, and we'll label it that way.
What does the Demented Circus trademark cover?
The filing is in Class 41, the entertainment class. The USPTO record lists a long menu of services:
Parks: amusement park, theme park and waterpark services and attractions
Shows: live show performances, plus street performers like balloon artists and stilt walkers
Characters: live appearances by costumed characters
Play: arcade services, interactive play areas for kids and adults, and escape rooms
Events: food festivals, running events and races, and concerts with DJs and dancing
Other: studio tours and movie theater services
That's a lot of ground for one creepy circus. A Demented Circus waterpark feels unlikely. A Demented Circus fun run feels even less likely.
There's a reason. This list is mostly Universal's standard parks language. When Universal filed for "Isle of Curiosity" on May 1, 2025, WDWNT printed a list with many of the same lines, from waterparks to escape rooms to DJ performances. So the waterpark line isn't a clue.
Who filed the Demented Circus trademark?
Universal City Studios LLC, a Delaware company based at 100 Universal City Plaza in Universal City, Calif. The attorney of record is Byron Barahona of NBCUniversal, per the USPTO.
It's the same Universal company that filed for Celestial Goodnight, the Epic Universe show in the video above, according to USPTO records.
What could Demented Circus be?
This part is speculation. Universal hasn't confirmed any use for the name.
WDWNT pointed to Jack the Clown and his partner Dr. Oddfellow from Halloween Horror Nights. It suggested Demented Circus could be part of a future Halloween Horror Nights or something at Universal Horror Unleashed, either in Las Vegas or the upcoming Chicago location.
The circus theme is already all over HHN. At Halloween Horror Nights 35 in Orlando this fall, the lineup included a house called Jack & Oddfellow: Chaos & Control and three circus-flavored scare zones, according to WDWNT's event guide:
Infernal Carnival of Nightmares in Minion Land
Downtown Clowntown in New York
Sideshow of Decay in Hollywood
Even the HHN 35 logo had a circus look, WDWNT noted when it was revealed in March. Jack was the icon of HHN 30, and his sidekick Chance was the 2016 icon.
Jack and Chance also star in a year-round show, Jack and Chance: Stay or Slay, at Universal Horror Unleashed in Las Vegas, WDWNT reported. Universal announced a second Horror Unleashed for Chicago in June 2025 and said it's slated to open in 2027.
So a few possible homes, all unconfirmed: an HHN 36 house or scare zone, a new Las Vegas experience, or the Chicago venue.
Do Universal trademarks turn into real attractions?
Sometimes, and sometimes fast. Two recent examples:
Universal Celestial Goodnight: filed Dec. 15, 2025, per the USPTO. The fireworks and fountain show debuted at Epic Universe on July 7, 2026, WDWNT reported. That's about seven months.
Isle of Curiosity: filed May 1, 2025. In October 2025, Universal named it as one of seven lands at Universal Kids Resort in Frisco, Texas, WDWNT reported. That's about five and a half months.
WDWNT also made a fair point back in 2025: a name on a trademark filing doesn't mean it will ever be used.
When will we know what Demented Circus is?
Universal hasn't said. The USPTO record doesn't give a date either. An intent-to-use filing gives a company time to launch before it has to prove the name is in use.
If it's for HHN, the timing could line up with Universal's usual spring and summer reveals for the fall event. The HHN 35 logo, for example, surfaced in March 2026. That's a guess based on past years, not a schedule.
We'll update when Universal confirms anything, or when the clowns do.
