What may a trade-mark include?

In Canada, a trade-mark may include: numbers, letters, words, a slogan, surnames, symbols, designs, or any combination of them. Colour may also be claimed as a feature of a trade-mark.

There is also a recent suggestion that sound and even smells may comprise proper subject matter of a trade-mark.

What is important is that the trade-mark be “distinctive”. It should be sufficiently different from trade-marks used by other people on similar products or with similar services so that no reasonable likelihood of confusion would occur. It should not be the name of the product or service or the name of any geographic area likely to be associated with the product or service. The more fanciful and distinctive the trade-mark, the more likely it is to be distinctive.
