Champion Spark Plug Co. v. Sanders

Background

A manufacturer sells spark plugs under the trade name “Champion.” A separate company collected used Champion plugs, repaired and reconditioned them, and resold them while keeping the word “Champion” on the plugs and on the outer cartons. The inside boxes and some markings said the plugs were renewed, but the reseller’s business name or address was not prominent on the cartons and the small “Renewed” stamp on each plug was sometimes nearly illegible. The District Court found trademark infringement and unfair competition and ordered strict labeling and removal steps; the Circuit Court of Appeals modified that order to allow the mark to remain if the reseller clearly stamped or baked “REPAIRED” or “USED” and disclosed the reseller’s name and address.

Reasoning

The central question was whether second‑hand goods that are repaired may still carry the original maker’s mark if buyers are not deceived. The Court explained that a trademark protects a maker’s goodwill against selling another’s product as its own, but it does not forbid truthful use of the mark to identify the original make. Because the reconditioning here restored the original plugs rather than creating a new product, and because there was no showing of fraud or deliberate palming off, clear and prominent disclosure satisfied the manufacturer’s rights. The Court also held that a money accounting was not required where an injunction and disclosure adequately protect the manufacturer.

Real world impact

Resellers of repaired branded goods can keep the original brand name when the goods are honestly described as used or repaired and the seller is identified. Manufacturers retain protection against deception, but they cannot force removal of the mark where full disclosure prevents consumer confusion. The Court affirmed the appeals court’s tailored labeling remedy and denied an accounting for profits.
