(3) The term “mark” includes any trademark or service mark entitled to registration under this chapter whether registered or not.

(4) The term “trade name” includes words and names lawfully adopted and used by any person engaged in any business, trade, occupation or vocation to identify such business, trade, occupation or vocation whether or not registered, filed or recorded under any law of the state of Connecticut, or of any other state, or of the United States.

(8) The term “use” means the bona fide use of a mark in the ordinary course of trade, and not made merely to reserve a right in a mark. For the purposes of this chapter, a mark shall be deemed to be in use (A) on goods when it is placed in any manner on the goods or their containers, or the displays associated therewith, or on the tags or labels affixed thereto, or if the nature of the goods makes such placement impracticable, then on documents associated with the goods or their sale, and such goods are sold or otherwise distributed in this state, and (B) on services when it is used or displayed in the sale or advertising of services and the services are rendered in this state.

(9) A mark shall be deemed to be “abandoned” (A) when its use has been discontinued with intent not to resume such use. Intent not to resume may be inferred from circumstances. Nonuse for two consecutive years shall be prima facie evidence of abandonment; (B) when any course of conduct of the registrant, including acts of omission as well as commission, causes the mark to lose its significance as an indication of origin.

(10) The term “related company” means any person whose use of a mark is controlled by the owner of the mark with respect to the nature and quality of the goods or services on or in connection with which the mark is used.

(11) The term “dilution” means the lessening of the capacity of the registrant’s mark to identify and distinguish goods or services, through use of the mark by another person, regardless of the presence or absence of (A) competition between the users of the mark, or (B) likelihood of confusion, mistake or deception arising from that use.
