In Algeria, trademark registration is mandatory to be granted rights over a trademark, as it is a “first to file” jurisdiction. Only in some exceptional cases can an unregistered trademark be protected.
Trademark applications must be filed with the Algerian National Institute of Industrial Property (INAPI). Algeria is also a member state of the Madrid Protocol, so you can extend an existing international trademark to Algeria through the Madrid System.
If you register a combined trademark (with both word and figurative elements), the exclusive right to use the mark is limited to the exact configuration in which it was filed and registered. If you want to use and protect the word or logo elements separately, it is recommended to file additional trademarks for those elements.
