In 1980, Security Center, Ltd. (Security Center) (plaintiff) opened The Security Center, a business that provided general security and leasing services for valuables, mail, and office space. In 1983, First National Security Centers (First National) announced that First National would soon begin construction on its own First National Security Centers, a business that would offer nearly the same exact services as The Security Center. Security Center brought a suit to prevent First National from featuring the term “security center” in the name of its business. The district court found The Security Center to be a suggestive trademark and held that the simultaneous use of First National Security Centers would likely result in customer confusion. A permanent injunction was issued to prevent First National from using the Security Center mark.
