A trade mark registration may be refused or, if registered, the registration may be invalidated, if the trade mark constitutes a reproduction, an imitation, a translation or a transliteration, liable to create confusion, of another trade mark, which, even though unregistered, was well-known in Latvia with respect to identical or similar goods or services, on the date of filing of application of the applied for (opposed) registration of trade mark (or the date of priority if priority has been granted).

In determining whether a trade mark is well-known, the knowledge of this trade mark in the relevant group of consumers, including such knowledge in Latvia that has been obtained as a result of the advertising of this mark or any other circumstances that have contributed to its fame shall be taken into account.
