How Do I Protect My Business's Trademark?

Distinctiveness Decides Whether You Have a Trademark at All

Trademark strength runs along a spectrum, and where your mark sits determines both whether you can register it and how easily you can enforce it. Coined or fanciful marks (invented words like Kodak), arbitrary marks (real words unrelated to the product, like Apple for computers), and suggestive marks (hinting at the product without describing it) are inherently distinctive and the strongest to own. Descriptive marks — which merely describe the product or its qualities — are weak: you can only register them by proving 'acquired distinctiveness' or secondary meaning through extensive use. Generic terms, the common name for the product itself, can never be a trademark.

This is why the choice of name is a legal decision as much as a marketing one. A distinctive mark is easier to register, cheaper to defend, and less likely to be attacked; a descriptive one may sail through marketing focus groups yet fail at the trademark office or crumble in litigation. If you still have the freedom to choose, choosing distinctiveness up front is the single highest-leverage trademark decision you can make — and even a strong mark must be used correctly (as an adjective before the generic product name) so it never degenerates into a generic term the way 'escalator' and 'aspirin' once did.

Registration, Territoriality, and Why Clearance Comes First

Trademark rights are territorial: a mark is valid only in the country where it is registered, and the systems differ. In the US, some common-law rights arise from use, but only within your actual geographic market — federal registration with the USPTO adds nationwide priority, a legal presumption of validity and ownership, the ® symbol, access to federal court, and a basis to block infringing imports. In Canada, unregistered marks get only limited protection through the tort of passing off where you can prove reputation; registration with CIPO grants exclusive rights across the whole country for the registered goods and services. Both countries belong to the Madrid Protocol, so a single international application off a home registration can extend protection to priority foreign markets.

Because rights hinge on clearing the field first, a clearance (or 'knockout') search of the trademark registers and common-law uses should precede any real investment in a brand. Adopting a name that conflicts with an existing mark can force an expensive rebrand and expose you to infringement liability — clearance is a fraction of the cost of rebranding after launch. Registration itself is limited to the goods and services classes you file in, so you must cover what you sell now and realistically plan to, and typically it is best to register the word mark first (it protects the name in any styling) and add a design/logo mark separately where the visual matters.

Enforcement: Confusion, Cease-and-Desist Letters, and Maintenance

Infringement in both countries turns on 'likelihood of confusion' — whether consumers would likely be confused about the source given the similarity of the marks and the relatedness of the goods and services. Acting promptly on infringement matters: undue delay can weaken your remedies and, in extreme cases, support a defence of acquiescence. But enforcement cuts both ways. A cease-and-desist letter is not a court order, and many are sent over weak or non-conflicting marks; if you receive one, neither ignore it nor capitulate reflexively — have a lawyer assess whether genuine confusion is likely and whether the sender's own mark is even valid before responding within the deadline.

Finally, a trademark is maintained by use and vigilance, not by a one-time filing. Non-use can lead to cancellation, so you must actually use the mark on the registered goods and services and keep evidence of that use; you should display it consistently, monitor the market and the registers for infringers, and renew on schedule (registrations run in fixed terms and must be renewed to survive). Trademarks are among the few business assets that can appreciate indefinitely — but only if you clear them properly, register them strategically, and police them consistently.
