Ohio Revised Code Title XXIX. Crimes Procedure § 2941.47

When an indictment is returned or information filed against a corporation, a summons commanding the sheriff to notify the accused thereof, returnable on the seventh day after its date, shall issue on praecipe of the prosecuting attorney. Such summons with a copy of the indictment shall be served and returned in the manner provided for service of summons upon corporations in civil actions. If the service cannot be made in the county where the prosecution began, the sheriff may make service in any other county of the state, upon the president, secretary, superintendent, clerk, treasurer, cashier, managing agent, or other chief officer thereof, or by leaving a copy at a general or branch office or usual place of doing business of such corporation, with the person having charge thereof. Such corporation shall appear by one of its officers or by counsel on or before the return day of the summons served and answer to the indictment or information by motion, demurrer, or plea, and upon failure to make such appearance and answer, the clerk of the court of common pleas shall enter a plea of “not guilty.” Upon such appearance being made or plea entered, the corporation is before the court until the case is finally disposed of. On said indictment or information no warrant of arrest may issue except for individuals who may be included in such indictment or information.
