Ohio Code § 1302.98

§ 1302.98.

(A) An action for breach of any contract for sale must be commenced within four years

after the cause of action has accrued.  By the original agreement the parties may reduce the period of limitation to not

less than one year but may not extend it. (B) A cause of action accrues when the breach occurs, regardless of the aggrieved party's

lack of knowledge of the breach.  A breach of warranty occurs when tender of delivery is made, except that where a

warranty explicitly extends to future performance of the goods and discovery of the

breach must await the time of such performance, the cause of action accrues when the

breach is or should have been discovered. (C) Where an action commenced within the time limited by division (A) of this section

is so terminated as to leave available a remedy by another action for the same breach,

such other action may be commenced after the expiration of the time limited and within

six months after the termination of the first action unless the termination resulted

from voluntary discontinuance or from dismissal for failure or neglect to prosecute. (D) This section does not alter sections 2305.15 and 2305.16 of the Revised Code on tolling of the statute of limitations, nor does it apply to causes of action which

have accrued before July 1, 1962.
