Meaning
Legal arguments raised in Chinese courts protect contract manufacturers from trademark infringement claims when producing goods solely for export. The oem trademark defense shields factories that manufacture products under a foreign buyer’s trademark, provided the goods are not sold within China. This defense relies on the argument that no domestic consumer confusion can occur.
Legal Foundation
This doctrine arose from the recognition that original equipment manufacturing does not perform the source-identifying function of a trademark in the local market. Because the finished goods are exported directly to foreign jurisdictions, the oem trademark defense asserts that the application of the mark is a technical step rather than a commercial sale in China. Consequently, domestic trademark registrations held by squatters cannot be used to block these export shipments.
This interpretation safeguards industrial production against predatory trademark filings designed to extort manufacturing plants.
Evidentiary Standard
Factories must present a complete paper trail to successfully assert this protection in court or before customs officials. Invoking the oem trademark defense requires providing the foreign trademark registration, the manufacturing agreement, and bills of lading showing the export destination. If any portion of the production is diverted to the domestic market, the defense is instantly invalidated.
Commercial Risk
Judicial interpretation of this defense has evolved, and some courts now demand higher levels of due diligence from Chinese manufacturers. Manufacturers must verify that the foreign buyer’s mark is validly registered in the country of import. This prevents litigation from disrupting production schedules.
It ensures that the factory operates within clear legal boundaries.
