Sales trademarks, also known as commercial trademarks or promotional trademarks, refer to the trademarks used by sellers on the goods they sell. The use of sales trademarks indicates that the goods sold by the operator are carefully selected and represents the business reputation of the operator. Operators use sales trademarks to gain credibility and put their products in an advantageous position in market competition.
