Oppositions

Someone applied at INPI for a trademark similar to yours. An opposition is the way to block that application before registration.

What you need to know

Every trademark application is published in the Industrial Property Journal (RPI) and stays open to opposition for 60 days. It is the window in which the owner of an earlier trademark — or an earlier application — can point out the conflict and ask INPI to refuse the new filing. Once the date passes, only the longer route of administrative nullity remains.

Regicenter monitors the publications for the trademarks it manages, warns you when a conflicting application appears and prepares the opposition with evidence of priority and use. On the other side, when the opposition is against your application, the defence is made through a response.

What Regicenter does
Monitoring of RPI publications
Analysis of the conflict and the chance of success
Drafting and filing of the opposition within 60 days
Follow-up until the decision on the merits
