Reputed mark

A reputed mark (marque de renommée, roughly mark de ruh-noh-MAY) is a registered trademark that has become known to a significant part of the relevant public. Its reward is an exception to the ordinary rules: enlarged protection that reaches beyond the principle of specialty.

Protection beyond the goods and services

Ordinarily a mark is protected only for identical or similar goods and services. A reputed mark breaks that limit. Under French and EU law, a later mark can be refused or invalidated even for dissimilar goods or services where, without due cause, its use would take unfair advantage of, or be detrimental to, the distinctive character or the repute of the earlier reputed mark. The three classic harms are free-riding (unfair advantage), blurring (dilution of distinctiveness) and tarnishment (damage to image). In France this protection is anchored in Article L.711-3 of the Intellectual Property Code; at EU level it flows from the EU trademark regulation and is administered by the EUIPO.

The key comparison with US law

The reputed mark is the functional counterpart of US dilution protection for famous marks under the Trademark Dilution Revision Act — blurring and tarnishment map directly onto US concepts. But two differences matter for US counsel:

• The threshold is lower in Europe. US dilution requires that the mark be famous to the general consuming public — a demanding, nationwide standard that few marks meet. The EU “reputation” test asks only that the mark be known by a significant part of the public concerned in a substantial part of the territory. Many marks that would fail the US “famous” test qualify as marques de renommée.
• It is built into opposition and invalidity practice, not confined to separate dilution litigation. A reputed mark can be invoked directly in an INPI or EUIPO opposition, and the protection is evaluated as part of the same administrative proceeding.

Reputed marks must be distinguished from well-known marks (marques notoires): the two are constantly confused. A reputed mark is registered and reaches dissimilar goods; a well-known mark can be unregistered but is protected essentially within its field.

A concrete example

Suppose a globally recognized luxury fashion house owns a French registration for its house name in clothing. A newcomer files the same name for industrial lubricants — plainly dissimilar goods, so ordinary specialty would let it through. Because the fashion mark enjoys a reputation, its owner can nonetheless oppose or invalidate the lubricant filing, arguing that the newcomer is trading on the prestige of the name (free-riding) or cheapening it (tarnishment).

Where you will meet this term

Reputed-mark protection is the headline exception you will study under third-party rights and relative grounds, and it is a recurring weapon when responding to a trademark opposition or building one. Because reputation must be proven with evidence gathered over time, it also raises the stakes of a systematic trademark watch.
