What is a trademark search?

A trademark search is an investigation of trademark registers and online usage to assess whether a proposed mark is available to adopt, use, and register. A trademark search is generally conducted before a business adopts a new brand name, logo, slogan, or product name, and before filing a trademark application with the Canadian Intellectual Property Office. The purpose of a trademark search is to identify confusingly similar marks that could block registration, expose the business to an infringement or passing off claim, or undermine the commercial value of the brand. A properly conducted trademark search is the foundation of any brand clearance and registration strategy.

Why you should consider a trademark search

Identifying blocking marks before investment. A trademark search can surface confusingly similar registered or pending marks before a business spends money on packaging, marketing, domain names, or a trademark application. Discovering a blocking mark after launch is far more costly than identifying it through a trademark search at the clearance stage.

Reducing the risk of infringement and passing off. Even a mark that is not registered can support an infringement claim under the Trademarks Act or a passing off claim at common law. A trademark search that covers both registered and unregistered uses helps assess the risk litigation before investing in a brand.

Improving the odds of registration. The Canadian Intellectual Property Office examines trademark applications for confusion with prior registered and pending marks. A trademark search conducted before filing can identify likely examiner objections, inform the choice of goods and services, and allow the applicant to narrow the application or adjust the mark to improve the likelihood of registration.

Supporting a registrability opinion. A trademark search is the factual foundation for a registrability opinion, which analyzes whether a mark is inherently distinctive, whether it is clearly descriptive or deceptively misdescriptive, and whether any confusingly similar prior rights exist. A registrability opinion based on a thorough trademark search is a useful tool for internal decision-making and investor due diligence.

Supporting brand strategy and franchise expansion. A trademark search can be tailored to specific goods and services, specific territories, and specific channels of trade. For a business planning to expand into new product categories, new provinces, or a franchise model, a trademark search helps map where the brand is free to grow.

Relevant laws and regulations

Trademarks Act, RSC 1985, c T-13. Canada’s federal trademarks legislation, which governs the registration, protection, and enforcement of trademarks and sets out the confusion analysis that is the central focus of any trademark search.

Trademarks Regulations, SOR/2018-227. The federal regulations under the Trademarks Act, which govern application procedures, the Nice classification of goods and services, and the register itself, all of which shape how a trademark search is conducted and interpreted.

Franchises Act, RSA 2000, c F-23. Alberta’s franchise legislation, which requires specific disclosure about the franchise system, including trademarks and rights to use them, and makes a trademark search particularly important for franchisors building out a brand for franchise expansion.

Common legal issues

Confusion with a prior registered or pending mark. The most common issue revealed by a trademark search is a confusingly similar registered or pending mark. The Trademarks Act sets out a multi-factor confusion test that considers the inherent distinctiveness of the marks, the length of use, the nature of the goods and services, the nature of the trade, and the degree of resemblance. A trademark search is used to apply this test before investing in a brand.

Common law rights that do not appear on the register. A trademark search that is limited to the federal register can miss significant common law rights. Unregistered marks with established use can support a passing off action and can block registration even without a registered filing. A thorough trademark search can include common law, business name, domain name, and marketplace evidence to capture these unregistered rights.

Descriptive, generic, or non-distinctive marks. A trademark search can reveal that a proposed mark is clearly descriptive, deceptively misdescriptive, or so crowded in the relevant field that it has low inherent distinctiveness. These issues affect registrability under the Trademarks Act and the commercial strength of the mark, and a trademark search helps identify them early.

Failure to clear beyond Canada. A Canadian trademark search alone may not surface relevant rights in the United States or other priority markets for a business planning international expansion. A trademark search scoped only to Canada can leave significant risk unaddressed in foreign jurisdictions that matter to the business.

Frequently asked questions

What is the difference between a knockout search and a full trademark search? A knockout search is a quick preliminary search of identical or near-identical marks on the Canadian register, used to rule out obviously unavailable marks. A full trademark search is a comprehensive availability search covering registered marks, pending applications, common law uses, and other sources to support a clearance or registrability opinion.

Is a trademark search required before filing a trademark application? A trademark search is not legally required before filing. It is generally used as a risk-management and strategy tool, because the Canadian Intellectual Property Office will examine the application for confusion regardless of whether a trademark search was conducted by the applicant.

Does a trademark search guarantee that a mark is available? A trademark search cannot guarantee availability. A trademark search reduces risk by identifying likely obstacles, but new filings, unregistered uses, and changes in the register after the date of the search can affect the conclusions.

Does a trademark search cover international markets? A standard Canadian trademark search covers Canada. International trademark searches are generally conducted on a country-by-country basis through foreign registers and are typically scoped to the markets most relevant to the business.

How often should a trademark search be updated? A trademark search is a point-in-time snapshot. For marks that are being developed over a long period, a refreshed trademark search is often conducted closer to launch or filing to capture new registrations and applications that may have been filed in the interim.
