Registering at CAC does not protect your brand name

A founder registers a company at CAC, sees their business name confirmed as available, and reasonably assumes the name is now theirs — nobody else can use it. That assumption is wrong, and it's wrong in a way that only becomes obvious once a competitor launches under a confusingly similar name and there's nothing to be done about it.

CAC checks your proposed name against its own register of company and business names. That's it. It says nothing about whether the name, logo, or slogan you're building a brand around is already claimed as a trademark by someone in a completely different registry — the Trademarks, Patents and Designs Registry, run by the Federal Ministry of Industry, Trade and Investment, now largely digitized through the Nigerian Industrial Property Office.

These are two different systems, checking two different things, with two different consequences. CAC registration gives you the right to operate as a legal entity under that name. Trademark registration gives you the right to stop others from using a confusingly similar mark on similar goods or services — the actual enforceable brand protection most founders think CAC already gave them.

The fix is simple and cheap relative to the mistake: search both registers before you commit to a name, not just one. If the brand is worth building a logo, packaging, and marketing around, it's worth the trademark filing — and worth doing early, before a year of brand equity is sunk into a name someone else can force you to abandon.

One more wrinkle worth knowing: trademark protection in Nigeria is filed per class of goods or services. Registering your software product name in the software class doesn't automatically protect it if someone launches an unrelated clothing line under the same name — a distinction that occasionally surprises founders expanding into merchandise or adjacent products.
