Ohio Revised Code Title XVII. Corporations Partnerships § 1703.191

Any foreign corporation required to be licensed under sections 1703.01 to 1703.31 of the Revised Code, which transacts business in this state without being so licensed, shall be conclusively presumed to have designated the secretary of state as its agent for the service of process in any action against such corporation arising out of acts or omissions of such corporation within this state, including, without limitation, any action to recover the statutory forfeiture for failure to be so licensed. Pursuant to such service, suit may be brought in Franklin county, or in any county in which such corporation did any act or transacted any business. Such service shall be made upon the secretary of state by leaving with him, or with an assistant secretary of state, duplicate copies of such process, together with an affidavit of the plaintiff or one of the plaintiff's attorneys, showing the last known address of such corporation, and a fee of five dollars which shall be included as taxable costs in case of judicial proceedings. Upon receipt of such process, affidavit, and fee the secretary of state shall forthwith give notice to the corporation at the address specified in the affidavit and forward to such address by certified mail, with a request for return receipt, a copy of such process.

The secretary of state shall retain a copy of such process in his files, keep a record of any such process served upon him, and record therein the time of such service and his action thereafter with respect thereto.

This section does not affect any right to serve process upon a foreign corporation in any other manner permitted by law.
