Ohio Revised Code Title XVII. Corporations Partnerships § 1706.513

(A) A foreign limited liability company whose name does not comply with section 1706.07 of the Revised Code may not file a registration as a foreign limited liability company until it adopts, for the purpose of transacting business in this state, an assumed name that complies with section 1706.07 of the Revised Code. A foreign limited liability company that adopts an assumed name under this division and then files a registration as a foreign limited liability company under that assumed name need not file a name registration when transacting business under that assumed name. After filing the registration as a foreign limited liability company under an assumed name, a foreign limited liability company shall transact business in this state under the assumed name unless the foreign limited liability company has filed a name registration under another name and is authorized to transact business in this state under such name.

(B) If a foreign limited liability company to which a registration as a foreign limited liability company has been filed changes its name to one that does not comply with section 1706.07 of the Revised Code, it may not thereafter transact business in this state until it complies with division (A) of this section by filing a certificate of correction.
