Pudgy Penguins Accused of Infringing: Legal Risks & Brand Impact

An escalating legal battle has emerged as PEI Licensing, owner of the Original Penguin apparel brand, files a trademark infringement lawsuit against Pudgy Penguins Inc. The case spotlights the growing tension between digital-native brands and established legacy trademarks.

Pudgy Penguins, originally an Ethereum-based NFT collection launched in 2021, has expanded into physical merchandise, including plush toys and apparel. PEI alleges that Pudgy Penguins’ use of names like “Pudgy Penguins,” “Pengu Nation,” and “Forever Pudgy Penguins” infringes on its long-standing trademarks, including “Penguin” and “Original Penguin” .

Background of the Dispute

PEI Licensing, which operates the Original Penguin brand, claims it has used a penguin logo since 1956 and the “Penguin” word mark since 1967 . The lawsuit, filed on March 4, 2026, in the U.S. District Court for the Southern District of Florida, alleges that Pudgy Penguins continued to use confusingly similar branding despite receiving a cease-and-desist letter in October 2023 .

PEI also filed opposition notices in 2024 against at least two Pudgy Penguins trademark applications with the U.S. Patent and Trademark Office (USPTO), yet the NFT brand persisted in using the marks and did not abandon its applications .

Scope of the Allegations

PEI’s complaint outlines several claims:

• Trademark infringement and dilution: Pudgy Penguins allegedly uses a “family of penguin trademarks” that are confusingly similar to PEI’s federally registered marks .
• Unfair competition: The lawsuit asserts that Pudgy Penguins’ actions mislead consumers into believing there is an affiliation with Original Penguin .
• Willful infringement: By continuing to use the marks after formal notice, Pudgy Penguins may face enhanced damages under federal law .

PEI is seeking a jury trial, monetary relief including all profits from the allegedly infringing sales, injunctive relief to halt use of the contested marks, and destruction of infringing products .

Business Impact and Market Context

Pudgy Penguins has successfully transitioned from a digital NFT project into a physical merchandise brand. In 2023, the company sold over one million plush toys through major retailers like Walmart and Target, generating more than $13 million in revenue . The brand has also expanded into apparel lines, including hoodies, hats, and sweatshirts .

PEI argues that this expansion into apparel directly competes with its own product lines, increasing the likelihood of consumer confusion . Pudgy Penguins reportedly targets $50 million in annual revenue and has ambitions to go public by 2027 .

Pudgy Penguins’ Response

Pudgy Penguins’ legal chief, Jennifer McGlone, expressed surprise at the lawsuit, noting that both parties had been engaged in productive private discussions . She asserted that the trademarks in question are visually distinct and serve different audiences and markets. McGlone emphasized that Pudgy Penguins has already secured multiple trademark application approvals from the USPTO .

Significance and Broader Implications

This case represents a pivotal moment in the evolving intersection of digital-native brands and traditional intellectual property law. Legal experts suggest it may set a precedent for how courts handle disputes involving NFT brands expanding into physical goods .

PEI’s aggressive enforcement of its trademarks—including a prior lawsuit against designer Thom Browne—demonstrates its commitment to protecting its brand identity . If the court finds Pudgy Penguins’ actions to be willful, PEI could be awarded enhanced damages and attorney fees .

For Pudgy Penguins, a ruling against them could disrupt their retail operations, damage partnerships, and impact their broader strategy, including token-related ventures like the PENGU token and co-branded products such as the KAST Pengu Card .

Conclusion

The lawsuit filed by PEI Licensing against Pudgy Penguins underscores the growing legal complexities facing NFT brands entering the physical marketplace. With decades-old trademarks at stake and millions in revenue on the line, the outcome could influence future digital-to-physical brand expansions. As the case unfolds, stakeholders across the NFT and apparel industries will be watching closely.
