991 F. Supp. 2d 888
S.D. Tex.2014Background
- T-Mobile (Deutsche Telekom affiliate) has used Pantone Process Magenta prominently in U.S. wireless marketing since 2002, spending billions and generating consumer recognition; it registered the color on the Supplemental Register in 2007.
- AT&T launched Aio (a no-contract flanker brand) using Pantone 676C (plum) with marketing dominated by large monochromatic swaths of plum; internal AT&T materials and focus groups noted similarity to T-Mobile magenta.
- T-Mobile sued for Lanham Act trademark infringement and dilution and moved for a preliminary injunction to stop Aio’s use of large swaths/blocks of plum in ads, stores, and websites.
- The court held a three-day evidentiary hearing with competing expert surveys and testimony on secondary meaning, likelihood of confusion, actual confusion, and consumer perception; Aio made post-filing marketing changes but sought to avoid injunctive relief.
- The court found (factually) that color is a critical source identifier in the wireless industry, that T-Mobile’s magenta acquired secondary meaning among its target consumers, and that Aio’s prominent use of plum is confusingly similar when presented as large swaths.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Protectability / Secondary meaning of single-color mark | T-Mobile: Pantone Process Magenta has acquired secondary meaning via long, pervasive use, ad spending, media coverage, and surveys | Aio: Registration on Supplemental Register, shade variation, non–stand-alone use, and third-party magenta use negate protectability | Court: Magenta is protectable (secondary meaning proven for relevant market) despite Supplemental Register and shade variation |
| Likelihood of confusion (infringement) | T-Mobile: products/services, retail channels, advertising media, and visual dominance of color create likely initial-interest and affiliation confusion | Aio: different slogans/brand personalities, high-involvement purchase decisions, and post-suit rebranding reduce confusion risk | Court: Likelihood of confusion found as to Aio’s use of large swaths/blocks of plum; several confusion factors weigh for T-Mobile |
| Irreparable harm & preliminary injunction | T-Mobile: loss of control over quality, diversion of customers, and loss of goodwill cannot be remedied by money; injunction necessary | Aio: no presumption of irreparable harm post-eBay; monetary damages suffice; injunction would impose heavy burdens/costs | Court: Irreparable harm found on this record (injunction narrowly tailored to bar large swaths/blocks of plum); harms to T-Mobile outweigh Aio’s remaining burdens |
| Dilution (TDRA fame) | T-Mobile: magenta is famous and dilution by blurring is likely | Aio: magenta not a household-famous mark; use in industry-specific context only | Court: TDRA claim failed — mark not sufficiently famous among general consuming public to support dilution claim |
