The DEMON HUNTER Trademark That Netflix Filed Right Past

Christian metal band Demon Hunter sued Netflix on August 18, 2026, in federal court in California over "KPop Demon Hunters," the animated musical that Netflix says has passed 600 million views — the most-watched original film in the company's history. The complaint, filed by the band's corporate entity Hyde Lane, names Netflix, Netflix Studios and concert promoter AEG Presents, and alleges the film and the 150-city live tour Netflix and AEG announced are swamping the band's identity and confusing its audience, per Variety's reporting. One anecdote from the coverage: a parent reportedly spent $500 on Demon Hunter concert tickets believing they were for the KPop Demon Hunters show, then asked the band for a refund. The complaint's own comparison, as quoted in press accounts: "Netflix is no more entitled to use the mark KPOP DEMON HUNTERS than it would be to launch a recording artist, live touring show, and merchandise under the marks KPOP METALLICA, KPOP U2 or KPOP BLACK SABBATH." Netflix has called the claims "without merit" and pointed to its own registered trademarks.

Here is what the coverage skips: the USPTO's public records show the band registered DEMON HUNTER for live performances back in 2014, kept that registration alive through one maintenance cycle — and then let it die in February 2025, four months before the movie premiered. The marks it is suing on today are a second set the band built in 2021. That sequence changes how you read the whole dispute.

The registration the band lost to a calendar

The band's original filing is DEMON HUNTER, serial 86161930: filed January 9, 2014 in Class 41 — the register's category for entertainment services — covering "Entertainment, namely, live performances by a musical band." It registered quickly, on August 12, 2014, as registration 4584097.

It is now dead. And unlike most register stories, this one narrates its own ending.

A U.S. trademark registration is not a file-once-and-forget asset. To keep it, the owner must periodically swear the mark is still in use — a filing called a Section 8 declaration, due between years five and six, then again at year ten alongside a Section 9 renewal. Miss the window and the USPTO cancels the registration automatically.

The band handled the first checkpoint. Its file history shows a Section 8 declaration received February 11, 2021 and accepted that June. The second checkpoint is the one that got away: the USPTO emailed a courtesy reminder on August 12, 2023, and on February 28, 2025 the record closes with "CANCELLED SEC. 8 (10-YR)/EXPIRED SECTION 9."

Hold that date. KPop Demon Hunters premiered in June 2025. Netflix's first KPOP DEMON HUNTERS trademark application arrived on July 22, 2025. The band's senior, first-in-time registration for exactly the thing now in dispute — live performances under the name DEMON HUNTER — had been dead for about five months.

The marks the band actually owns

The 2021 paperwork burst tells you the band's counsel was doing real housekeeping. In the same week it filed that six-year maintenance declaration, Hyde Lane filed three fresh DEMON HUNTER applications on February 15, 2021, and all three registered together on January 4, 2022:

• Class 9 (serial 90529137, reg. 6607085) — audio and musical recordings and downloadable music
• Class 16 (serial 90529142, reg. 6607086) — stickers, posters, printed tickets and event programs
• Class 25 (serial 90529145, reg. 6607087) — clothing, from shirts to footwear

Those three live registrations are the ones the lawsuit stands on. Note what is missing: Class 41, live performances. But the fair reading is not that the band forgot it — in February 2021 it still owned the 2014 Class 41 registration and had just paid to maintain it. The hole only opened in February 2025, when the ten-year renewal lapsed. Choosing classes is strategy; keeping them is calendar work, and this was a calendar failure, not a strategy failure.

The band's most recent move confirms it knows exactly where the hole is. On December 3, 2025 — months after the film exploded — Hyde Lane filed a new DEMON HUNTER application, serial 99528509, back in Class 41 for live musical performances. Calling it "pending" undersells the situation: the USPTO has mailed a suspension letter, meaning the application is on hold. Two Netflix applications in the same class were filed months ahead of it.

Netflix moved wide — but read the goods, not the class numbers

Netflix Studios filed ten KPOP DEMON HUNTERS applications between July and November 2025, across seven classes. Five are already registered. The first, serial 99296783 for stuffed and plush toys (Class 28), was filed July 22, 2025 and registered July 21, 2026 — four weeks before the band sued. An August 2025 wave added action figures and toys (99341348), housewares (99347670, Class 21), textiles (99347945, Class 24), furniture-class goods (99348280, Class 20) and a Class 9 filing (99347846); four of those five registered together on March 24, 2026. Netflix also registered the film's fictional bands, HUNTR/X and SAJA BOYS, across merchandise classes.

On paper that looks like a head-on collision with the band's Class 9 registration. It mostly is not — and this is where class numbers mislead. Netflix's registered Class 9 covers decorative magnets, laptop sleeves, mouse pads and phone cases; its November Class 9 application (99485920) covers downloadable game software. The band's Class 9 registration covers music recordings. Same bucket, different goods — and in a confusion fight, what actually collides is the goods and the marks, not the class labels.

The genuinely close quarters are in Class 41. Netflix filed there twice: an August 2025 application (99361522) for streaming and multimedia content, now published for opposition, and a November 2025 application (serial 99485888) that includes "live theatrical, musical, and comedic performances" — the band's home turf. And here the register says something the news coverage has not: the USPTO has mailed final refusals on both of Netflix's November applications, the live-performance Class 41 and the game-software Class 9. A final refusal is the examiner's last word before an applicant must appeal or change the examiner's mind. The register does not say why they were refused. What it shows is a standoff: the two Netflix applications that reach closest to the band are stalled at the agency, and the band's own live-performance refiling is suspended. The court fight and the register fight are running on different clocks.

What a founder should take from this

DEMON HUNTER itself is a cautionary tale in thirteen acts: the register holds thirteen applications for exactly that mark since 1993 — Hasbro had one, Konami tried one — and of the seven now dead, four were cancelled under Section 8. Not lost to a rival. Lost to a missed maintenance filing.

First, a registration is a maintenance obligation, not a trophy. The band's most valuable asset — a 2014-priority registration for live performances — died even though the USPTO emailed a reminder a year in advance. Section 8 and 9 deadlines deserve the same docketing discipline as payroll.

Second, when you assess a conflict, read the goods, not the class number. The scary-looking Class 9 overlap here dissolves on inspection; the real overlap sits in a class the band currently holds no registration in at all.

Third, timing compounds. Netflix locked five registrations before its tour was even announced. The band's answering filing came in December 2025 and now waits in suspension. In priority disputes, months are not a rounding error.

A monitoring tool that flags new filings against your marks — by class, by owner, by filing date — surfaces a KPOP DEMON HUNTERS the same business day it enters the register, and watching your own portfolio for approaching maintenance deadlines is the quieter half of the same job. That is the part of this story GleanMark exists to make boring.
