Miss. Code Ann. § 75-93-13

Notwithstanding the provisions of any other law, registration of a fictitious business name under this chapter is for public notice only and gives rise to no presumption of the registrant’s exclusive rights to own or use the fictitious business name registered, nor does it affect trademark, service mark, trade name, or other name rights previously acquired by others in the same or similar name. Registration under this chapter does not preserve a fictitious business name against future use or registration by others. The issuance of a registration under this chapter shall not constitute due organization or authority to transact business in this state.
