yeah, but they don't have to change the name of the store.

Many people believe that if they register a particular domain, for example www.arkansascoffee.com, then the person has trademarked that as a business name an no one else can use the name Arkansas Coffee for their business. This is not necessarily true. You must not only register the domain, but use the business name enough to achieve distinction, such as through customer awareness and marketing.

Trademarks can be distinctive words, phrases, logos, symbols, slogans or other things that identify the source of the product and make it distinctive. A trademark can either be inherently distinctive, or it can gain its distinctiveness over a period of time by being associated with a particular product or service (for instance, the Nike swoosh).
