What is INAPI in Algeria?

INAPI (the Algerian National Institute of Industrial Property) is the public body responsible for registering and protecting trademarks, invention patents, industrial designs and models, and appellations of origin in Algeria.

How do you file a trademark with INAPI?

File online through the INAPI portal or in person at the head office in Algiers: form + reproduction of the trademark + list of goods and services (Nice classification) + proof of payment of the fees.

What does it cost to file a trademark?

Official INAPI schedule: 15 000 DA to file and publish a trademark without a colour claim, 16 000 DA with a colour claim. Each class adds 2 000 DA up to the third class, then 5 000 DA per class beyond. The prior-art search is billed separately: 1 600 DA for an identity search, 3 000 DA for a similarity search over 3 classes.

How long does the procedure take?

On average 6 to 9 months between filing and registration. The trademark is protected from the filing date (right of priority), but official registration is what validates the protection.

What is a prior-art search?

A check that the desired trademark has not already been filed and is not likely to be confused with an existing trademark. It is crucial in order to avoid a rejection or a third-party opposition.

Can you file a patent with INAPI?

Yes. INAPI receives applications for invention patents (20 years of protection) and utility models (10 years). A technical description, claims and sometimes an international search are required.

How do you defend against counterfeiting?

File an opposition with INAPI within 2 months of publication, or bring an infringement action before the court. A registered trademark is the basis of any action.
