The H3H3 lawsuits span nearly a decade and now cut in both directions: Ethan Klein won a landmark fair use ruling as a defendant in 2017, then became a plaintiff in a wave of 2025 copyright suits against reaction streamers, while also fighting a defamation case brought by producer Ryan Kavanaugh, settling a $50 million copyright claim from Triller, and briefly suing fellow YouTuber iDubbbz before dropping the case. Several matters are still live as of mid-2026.
The 2025 Copyright Suits Against Reaction Streamers
In June 2025, Klein’s production company, Ted Entertainment Inc. (TEI), filed copyright infringement lawsuits in the U.S. District Court for the Central District of California against three Twitch streamers: Alexandra Saber (“Denims”), Kaceytron, and Frogan (Morgan Kamal Majed).1Copyright Lately.

The suits also named anonymous moderators of the Reddit community r/h3snark as Doe defendants, alleging contributory infringement for directing users to watch the streamers’ broadcasts as a way to avoid supporting Klein’s original content.1Copyright Lately. Klein Reaction Video Lawsuits Update
Denims: Fair Use Tentative Ruling, Now Under Submission
The most substantively litigated of the three is Ted Entertainment, Inc. v. Saber (Case No. 2:25-cv-05564), before Judge Wesley L. Hsu.4Copyright Lately. Ethan Klein Denims Reaction Video Fair Use Tentative Ruling Denims filed a motion for judgment on the pleadings, arguing that her four-hour Twitch stream, which included 211 pauses and a live chat panel alongside her commentary, was a fundamentally different experience from Klein’s polished documentary and therefore fair use.1Copyright Lately. Klein Reaction Video Lawsuits Update Her lawyers also pointed to TEI’s own complaint, which had described her use as “highly transformative” because she employed the documentary for the “exact opposite purpose” of the original.
On June 7, 2026, Judge Hsu issued a tentative ruling finding fair use as a matter of law, concluding that three of the four statutory factors favored Denims and citing Hosseinzadeh v. Klein and Stebbins v. Alphabet. After about 40 minutes of oral argument, however, the judge took the matter under submission rather than adopting the ruling from the bench. No final order had been issued as of mid-2026.4Copyright Lately. Ethan Klein Denims Reaction Video Fair Use Tentative Ruling
Kaceytron Settled and Apologized
Kaceytron (Kacey Caviness) settled in December 2025. She released an apology video admitting copyright infringement and acknowledging that the Kleins’ lawsuit was not frivolous, and she agreed to transfer her remaining GoFundMe proceeds to TEI, though the dollar amount was not disclosed.1Copyright Lately.

The Fight to Unmask the r/h3snark Moderators

Ryan Kavanaugh’s Defamation Case Against Klein
Film and television producer Ryan Kavanaugh sued Klein and TEI for defamation in Los Angeles Superior Court, alleging that Klein repeatedly and falsely accused him of running a Ponzi scheme.9Yahoo News. YouTuber Ethan Klein Loses Anti-SLAPP Motion The claim traces back to a June 2019 Variety article about a lawsuit by Kavanaugh’s former business partner Elon Spar. Variety updated the article the next day to note that the parties had resolved the matter, that the complaint had been filed by accident, and that Spar himself said Kavanaugh was not running a Ponzi scheme.10Metropolitan News-Enterprise. Defamation Kavanaugh alleged Klein continued to republish the accusation over months despite the retraction, beginning in June 2021 in retaliation for Triller’s copyright suit (Kavanaugh was affiliated with Triller).
Klein and TEI filed an anti-SLAPP motion, which Judge H. Jay Ford III denied. On April 3, 2025, the California Court of Appeal affirmed, finding that the “fair and true report” privilege did not protect Klein because his statements omitted the context that the accusation had been withdrawn. The court also rejected the argument that Klein’s posts were mere memes lacking factual assertions, noting that Klein bolstered the claims by citing Variety‘s reputation, and it held that the omission of essential facts supported a finding of actual malice.10Metropolitan News-Enterprise. Defamation With the anti-SLAPP motion denied, Kavanaugh’s claims can proceed to discovery and trial.
The Triller Copyright Suit
In May 2021, Triller Fight Club II LLC sued Klein, his wife Hila Klein, TEI, and their clothing brand Teddy Fresh Inc. for copyright infringement in the Central District of California, seeking $50 million.11Business Insider.

The Short-Lived iDubbbz Defamation Suit
In 2026, Klein filed a defamation lawsuit in Calgary, Alberta, against fellow YouTuber Ian “iDubbbz” Jomha. The suit followed a February 2026 livestream in which iDubbbz, using an alter-ego character, displayed a message from streamer Steven “Destiny” Bonnell that accused Klein of molesting his own children.13Primetimer. iDubbbz’s Comments About Ethan Klein Explored Klein alleged iDubbbz presented the message without its original context, turning what Klein characterized as a provocative remark into a damaging allegation.14NDTV Sports.

Where It Started: Hosseinzadeh v. Klein
The case that made Klein a central figure in online copyright law was Hosseinzadeh v. Klein, filed in May 2016 in the Southern District of New York.17Forbes. H3H3 Productions Scores Tentative Win for Fair Use Online Filmmaker Matt Hosseinzadeh sued Ethan and Hila Klein over a 14-minute reaction video featuring clips from and commentary on his five-minute “Bold Guy” skit, alleging copyright infringement and later adding defamation and misrepresentation claims.
On August 23, 2017, Judge Katherine Forrest granted summary judgment for the Kleins, ruling the video was fair use as a matter of law.18U.S. Copyright Office. Hosseinzadeh v. Klein, No. 16-CV-3081 The court found the first fair use factor weighed “heavily in defendants’ favor” because the video was “quintessential criticism and comment,” and that it did not serve as a market substitute for the original. Judge Forrest cautioned that the ruling was not blanket protection for reaction videos, warning that some might amount to “a group viewing session without commentary.”19BBC News. YouTube Stars Win High-Profile Fair Use Court Battle That caveat is what TEI is now leaning on in the 2025 reaction-streamer suits.
Where the Cases Stand
As of mid-2026, Klein has active litigation on several fronts. The Denims copyright case is under submission with a fair use tentative ruling pending finalization. Frogan is in default, with no default judgment yet sought. The r/h3snark subpoena fight is unresolved before Magistrate Judge Kim. Kavanaugh’s defamation case is heading past the anti-SLAPP stage into discovery. The Kaceytron and iDubbbz matters are closed, one by settlement and apology, the other after iDubbbz’s public apology led Klein to drop the case. Triller was settled in 2024. Klein’s legal footprint, once defined by a single fair use win, now runs across copyright, defamation, and online-speech proceedings in California, New York, and Alberta.
