Trademarks and service marks (word marks, device marks and combinations thereof, 3-dimensional marks, sound and light marks). Besides the original version, filing of word mark applications in the Cyrillic alphabet is highly recommended, as the Tajik language uses the Cyrillic alphabet, and Russian still being a parallel language in this country.

A trade mark which is not used during any three-year period after the registration date (or the last date of use), may be cancelled upon request filed by an interested party; nominal use (advertising, publications) is accepted in absence of actual use.
