trademark confusion

It is really hard to determine if a trademark is confusing.

The Canadian Legislation says:

When mark or name confusing

6. (1) For the purposes of this Act, a trade-mark or trade-name is confusing with another trade-mark or trade-name if the use of the first mentioned trade-mark or trade-name would cause confusion with the last mentioned trade-mark or trade-name in the manner and circumstances described in this section.

Idem

(2) The use of a trade-mark causes confusion with another trade-mark if the use of both trade-marks in the same area would be likely to lead to the inference that the wares or services associated with those trade-marks are manufactured, sold, leased, hired or performed by the same person, whether or not the wares or services are of the same general class.

Idem

(3) The use of a trade-mark causes confusion with a trade-name if the use of both the trade-mark and trade-name in the same area would be likely to lead to the inference that the wares or services associated with the trade-mark and those associated with the business carried on under the trade-name are manufactured, sold, leased, hired or performed by the same person, whether or not the wares or services are of the same general class.

Idem

(4) The use of a trade-name causes confusion with a trade-mark if the use of both the trade-name and trade-mark in the same area would be likely to lead to the inference that the wares or services associated with the business carried on under the trade-name and those associated with the trade-mark are manufactured, sold, leased, hired or performed by the same person, whether or not the wares or services are of the same general class.

What to be considered

(5) In determining whether trade-marks or trade-names are confusing, the court or the Registrar, as the case may be, shall have regard to all the surrounding circumstances including

(a) the inherent distinctiveness of the trade-marks or trade-names and the extent to which they have become known;

(b) the length of time the trade-marks or trade-names have been in use;

(c) the nature of the wares, services or business;

(d) the nature of the trade; and

(e) the degree of resemblance between the trade-marks or trade-names in appearance or sound or in the ideas suggested by them. [R.S., c.T-10, s.6.]

TRIPS adopted the Paris Convention on this issue:

(1) The countries of the Union undertake, ex officio if their legislation so permits, or at the request of an interested party, to refuse or to cancel the registration, and to prohibit the use, of a trademark which constitutes a reproduction, an imitation, or a translation, liable to create confusion, of a mark considered by the competent authority of the country of registration or use to be well known in that country as being already the mark of a person entitled to the benefits of this Convention and used for identical or similar goods. These provisions shall also apply when the essential part of the mark constitutes a reproduction of any such well-known mark or an imitation liable to create confusion therewith.

(2) A period of at least five years from the date of registration shall be allowed for requesting the cancellation of such a mark. The countries of the Union may provide for a period within which the prohibition of use must be requested.

(3) No time limit shall be fixed for requesting the cancellation or the prohibition of the use of marks registered or used in bad faith.

This allows well known companies to get rid of copycats and usurpers in third world countries.
