(law) A mark used in sales or advertising to identify a service offered by an individual or legal entity and to distinguish that service from services offered by others. A service mark is distinguished from a trademark in that the former identifies services, while the later identifies goods. Protection for service marks varies from country to country, and may not be available in some jurisdictions. Service marks are often, but not necessarily, regulated by the same laws that govern trademarks. A country that is a member the Paris Convention for the Protection of Industrial Property may recognize service marks held in other jurisdictions. See trademark; patent; Paris Convention; World Intellectual Property Organization.
