The difference between a service mark and a trademark is a matter of semantics. A service mark is a trademark. However, the term "service mark" is used to refer to trademarks for services. The term "trademark" is often used in a broader sense to describe marks used in connection with goods and/or services.
Regardless of whether you are offering goods or services in connection with your trademark, the experienced attorneys of Smith & Hopen can advise you on all things trademark. Contact us for additional information or a free consultation.
