Background
Tiffany & Co., the luxury jeweler, conducted test purchases on eBay and found that a substantial proportion of items listed as “Tiffany” jewelry were counterfeit. Tiffany regularly sent eBay notices of specific infringing listings, and eBay removed those listings through its Verified Rights Owner (VeRO) program. However, Tiffany argued that eBay’s general knowledge that counterfeits were widely present — coupled with its continuing to profit from the platform — made eBay contributorily liable for the third-party sellers’ infringement.
After a bench trial, the Southern District of New York ruled in eBay’s favor on contributory infringement. Tiffany appealed, arguing that eBay’s generalized awareness of widespread counterfeiting on the platform was sufficient to establish the “knew or had reason to know” element of contributory trademark infringement under the Inwood Laboratories framework.
The Court’s Holding
The Second Circuit affirmed. Applying the Inwood Laboratories standard, the court held that a defendant is contributorily liable for trademark infringement if it “intentionally induces another to infringe a trademark” or if it “continues to supply its product to one whom it knows or has reason to know is engaging in trademark infringement.” The court drew a critical distinction between generalized knowledge and specific knowledge: eBay’s general awareness that some users sold counterfeit Tiffany goods was not sufficient to establish contributory liability as to any particular infringing transaction.
The court held that when eBay received specific notice of particular infringing listings and promptly removed them through VeRO, it had satisfied its obligations. eBay was not required to preemptively police all listings or assume that any listing of Tiffany goods was counterfeit. Contributory liability required specific knowledge — knowing or having reason to know that a particular listing or seller was infringing — not merely platform-level awareness that infringement was occurring at some scale.
Key Takeaways
- Contributory trademark infringement under Inwood Laboratories requires specific knowledge of particular infringing listings or sellers, not merely generalized awareness that a platform hosts some amount of counterfeit goods.
- Online marketplaces that promptly respond to takedown notices for specific infringing listings generally satisfy their anti-infringement obligations under contributory trademark liability doctrine.
- The burden of policing counterfeit listings falls primarily on the trademark owner — who must identify and report specific infringers — rather than on the platform, which has no duty to make proactive, platform-wide investigative sweeps without specific notice.
- The ruling established a framework that has governed platform liability for counterfeit goods cases in U.S. courts, though it has been criticized as insufficiently protecting brand owners against sophisticated counterfeiting operations that continuously re-list goods after removal.
Why It Matters
Tiffany v. eBay was one of the most significant trademark decisions of the e-commerce era. The case directly addressed the core business model question for online marketplaces: to what extent are platforms like eBay, Amazon, and Alibaba legally responsible for trademark infringement by their third-party sellers? The Second Circuit’s answer — that generalized awareness of counterfeiting is insufficient, and specific notice is required — gave online marketplaces substantial legal protection from brand owner suits.
The ruling has been both celebrated and criticized. For platform operators, it confirmed that a notice-and-takedown approach to trademark infringement, similar in spirit to the DMCA’s copyright safe harbor framework, was legally sufficient. For brand owners, it meant bearing the burden of constant monitoring and specific notice — a resource-intensive process — to enforce their rights online. The case remains a foundational reference point in the ongoing global debate about marketplace liability for counterfeit goods, a debate that continues in U.S. and European regulatory proceedings today.
