“Registration of a fictitious name does not create any exclusive right to use the fictitious name. There are no ownership rights to a fictitious name. Other individuals or entities may register the same fictitious name. A fictitious name registration is not a trademark or copyright. Registration of a fictitious name does not provide liability protection. The use of a fictitious name does not create a separate legal entity, but is merely descriptive of a person or association who does business under another name.”
