Service marks are a type of trademark that specifically identifies and distinguishes the services of one provider from those of others. Unlike goods, which are represented by trademarks, service marks play a crucial role in branding services such as entertainment, education, and hospitality, ensuring that consumers can identify the source of a service. Understanding service marks is essential in navigating issues like naked licensing, social media brand protection, influencer marketing, and the challenges of online marketplaces with counterfeiting.
