What are the challenges of zombie trademarks?

Propriété intellectuelle, marques The protection of intangible assets as well as the efficient management of zombie trademarks or patents  portfolio contribute to the proper development of a company and its business.

Building a reputation is the very goal of any brand. This reputation is normally attached in law to the sign and to the company that filed and operates it. However, in the context of zombie trademarks, the mark does not symbolize the reputation of the current owner but that of the original owner.

Indeed, these zombie trademarks are signs that have been abandoned but still have marketing potential, a reputation.

A zombie trademark presupposes an indisputable relinquishment, that is to say an abandonment both in fact and legally. It then falls into the public domain.

As long as a brand continues to be used and is renewed every ten years, it can exist perpetually, contrary to patents and the author’s economic rights. However, sometimes a company discontinues the use of some of these signs.

This abandonment can occur any time, whether while the filing is still under review or even when the sign has been in use for a long time. In terms of non-use, a sign is abandoned when a holder stops using it without the intention of resuming its operation, for five consecutive years according to Article L 714-5 of the French Code of Intellectual Property.

Although perpetually renewable, in practice the vast majority of brands have a limited lifespan. They are born and they die. However, it happens that some experience a different fate. They are resurrected.


As we can see with the zombie trademarks, abandonment doesn’t have to be permanent.

A company that has given up its rights to a trademark cannot normally prevent a newcomer from bringing a trademark “back from the dead”. Indeed, the disputed sign has returned to the public domain, which theoretically allows anyone to be able to dispose of it freely.

An abandoned trademark is in principle available to everyone.

In France, it is possible to take action against a so-called deceptive brand. Article L. 711-3 c) of the French Intellectual Property Code provides that signs “likely to deceive the public, in particular as to the nature, quality or geographical origin of the product or service” cannot be adopted as a trademark. The former owner also sometimes has the opportunity to initiate ​​unfair and parasitic competition claims.

Resurrecting a brand can thus be of major asset for a company wishing to take advantage of the notoriety of a distinctive sign that has returned to the public domain. However, some of these marks are not legally neither quite dead, nor quite alive, and it is advisable to be very careful, given that the case law is still rare and uncertain on this subject.
