Poppy Playtime Schedule A Lawsuit Targets Online Sellers

Mob Entertainment, Inc. has filed a new Poppy Playtime Schedule A lawsuit against online sellers accused of selling counterfeit and infringing products. The lawsuit was filed on September 24, 2026, in the U.S. District Court for the Northern District of Illinois under Case No. 1:26-cv-11737.

If Poppy Playtime sounds familiar, this is not the first time we have covered Mob Entertainment’s efforts to enforce its intellectual property against e-commerce sellers. In July 2024, we discussed an earlier Poppy Playtime trademark and copyright infringement lawsuit involving online sellers. You can read our previous Poppy Playtime infringement lawsuit article for additional background.

This latest case is another reminder that online sellers need to pay close attention to the intellectual property connected to the products they list. If your store has been named as a Defendant in this lawsuit, ignoring the case could have serious consequences.

What Is Poppy Playtime?

For anyone unfamiliar with the name, Poppy Playtime is a survival-horror video game franchise developed by Mob Entertainment. The first chapter of the game was released in 2021 and follows a protagonist investigating the mysterious abandonment of the fictional Playtime Co. toy factory. Players solve puzzles while encountering characters and creatures associated with the factory.

The franchise includes recognizable characters such as Huggy Wuggy, Mommy Long Legs, Poppy, Kissy Missy, CatNap, Boxy Boo, and the Smiling Critters. The complaint also shows how much the franchise has expanded since the lawsuit we covered in 2024. Mob Entertainment states that Chapter 4, Safe Haven, was released in January 2025 and Chapter 5, Broken Things, followed in February 2026.

According to Mob Entertainment, Poppy Playtime has developed a substantial audience across gaming and social media platforms. The company alleges that Chapter 1 playthrough videos have accumulated billions of views across YouTube and TikTok and that the game has reached 11 million downloads across PC and mobile.

That popularity extends beyond the games themselves. Mob Entertainment also sells and licenses Poppy Playtime merchandise, including stuffed toys, posters, and clothing.

What Does Mob Entertainment Claim in the New Lawsuit?

Mob Entertainment alleges that the Defendants operate e-commerce stores using seller aliases and have offered products containing unauthorized versions of its trademarks and copyrighted works.

According to the complaint, these stores target U.S. consumers, including consumers in Illinois, accept U.S. dollars, and allegedly sold products containing counterfeit trademarks and/or unauthorized copies of copyrighted Poppy Playtime material.

The company claims these sellers use online storefronts that can appear to consumers to be legitimate retailers, wholesalers, or outlets. Mob Entertainment further alleges that the Defendants were not licensed or authorized to use its trademarks or copyrighted works and were not authorized retailers of genuine Poppy Playtime products.

Importantly, these are allegations made by Mob Entertainment in its complaint. Whether a particular Defendant actually engaged in the conduct alleged will depend on the facts surrounding that seller and its listings.

Which Poppy Playtime Trademarks Are Involved?

This lawsuit is broader than the POPPY PLAYTIME name alone.

Mob Entertainment identifies several federally registered trademarks that it says are involved in the case, including:

POPPY PLAYTIME — Registration No. 7,157,530

SMILING CRITTERS — Registration No. 7,572,536

CATNAP — Registration No. 7,662,706

HUGGY — Registration No. 7,683,545

BOXY BOO — Registration No. 7,392,878

MOMMY LONG LEGS — Registration No. 7,523,931

The complaint also identifies a substantial collection of copyrighted Poppy Playtime material. These works include depictions of characters and other elements associated with Poppy Playtime and PROJECT: PLAYTIME, including Huggy Wuggy, Mommy Long Legs, Poppy, Kissy Missy, the Grab Pack, CatNap, Yarnaby, the Smiling Critters, and numerous other characters and designs.

This matters because Mob Entertainment is not bringing only a trademark claim. The lawsuit asserts both trademark and copyright infringement claims.

What Claims Are Being Made Against the Sellers?

Mob Entertainment brings three primary causes of action against the Defendants.

The first is trademark infringement and counterfeiting under the Lanham Act. Mob Entertainment alleges that the Defendants used counterfeit reproductions of its registered trademarks in connection with advertising, distributing, offering, and selling unauthorized goods.

The second is false designation of origin. The company alleges that the sellers' use of the Poppy Playtime trademarks could cause consumers to mistakenly believe that the products were affiliated with, sponsored by, or approved by Mob Entertainment.

The third is copyright infringement. Mob Entertainment alleges that Defendants copied, displayed, distributed, reproduced, or created derivative works from protected Poppy Playtime artwork without authorization.

For an online seller, that distinction can be important. A listing does not necessarily have to use only the words "Poppy Playtime" to raise an intellectual property issue. Character artwork, logos, designs, product images, and other protected material may also form the basis of an infringement allegation.

Why Is This a Schedule A Lawsuit?

Rather than filing a separate lawsuit against each seller, Mob Entertainment has brought one action against multiple online sellers identified on a Schedule A.

The company alleges that the sellers operate through various aliases and use similar methods to conceal their identities and continue selling unauthorized products. Mob Entertainment further alleges that some sellers create or acquire new seller aliases to avoid enforcement efforts.

For sellers, a Schedule A lawsuit can move differently from an ordinary marketplace intellectual property complaint. You are no longer dealing only with an Amazon, eBay, Etsy, Temu, Walmart, or other platform complaint. You are dealing with litigation in federal court.

That distinction should not be ignored.

What Is Mob Entertainment Asking the Court to Do?

Mob Entertainment is requesting substantial relief from the Court.

Among other things, the company asks for orders preventing Defendants from using the Poppy Playtime trademarks or copyrighted works in connection with unauthorized products. It also seeks orders that could require online marketplace platforms with notice of the injunction to disable advertisements associated with the allegedly infringing products.

The requested monetary relief is also significant.

Mob Entertainment asks for the Defendants' profits and damages and, alternatively, seeks statutory damages of up to $2 million for each use of a Poppy Playtime trademark in cases of willful counterfeiting. For copyright infringement, the complaint alternatively requests statutory damages of up to $150,000 per infringed work, along with attorneys' fees and costs.

These are amounts requested in the complaint, not amounts that the Court has necessarily awarded against any particular Defendant.

We Covered a Poppy Playtime Lawsuit Before. What Has Changed?

When we first covered a Poppy Playtime infringement lawsuit in July 2024, Mob Entertainment was already pursuing online sellers accused of selling counterfeit Poppy Playtime merchandise.

More than two years later, the September 2026 complaint shows that Mob Entertainment continues to pursue infringement involving the Poppy Playtime brand.

The intellectual property portfolio identified in the new complaint has also expanded. The lawsuit references newer characters and copyrighted material associated with later Poppy Playtime releases, including content registered in 2024 and 2025.

For e-commerce sellers, that expansion is worth paying attention to. Older listings are not the only potential source of infringement allegations. As entertainment franchises introduce new characters, games, artwork, merchandise, and branding, the amount of intellectual property associated with those franchises can grow as well.

What Should You Do If You Were Named in the Poppy Playtime Lawsuit?

If you received notice that your store or seller alias is included in Mob Entertainment, Inc. v. The Partnerships and Unincorporated Associations Identified on Schedule A, Case No. 1:26-cv-11737, do not assume that removing the listing will resolve the lawsuit.

Review the complaint, determine which store and products are at issue, preserve your sales and listing records, and pay close attention to any deadlines contained in the court documents you receive.

Most importantly, remember that the allegations against the group of Defendants do not necessarily establish what happened with your individual store. Your sales history, listings, products, suppliers, use of Poppy Playtime intellectual property, and other facts may affect how your particular case should be handled.
