OH HB665

Prohibits using or distributing pricing algorithms that incorporate nonpublic competitor data, such as confidential pricing information or commercial terms from market competitors

Creates a legal presumption of antitrust conspiracy when a pricing algorithm using nonpublic competitor data is distributed to or used by two or more competing businesses in the same market

Requires businesses with $5 million or more in annual gross receipts to disclose to customers before purchase, and to employees/contractors, when prices or compensation are set by a pricing algorithm

Mandates disclosure of whether the algorithm sets different prices for different customers seeking identical products, and requires identifying who developed or distributed the algorithm

Violations of disclosure requirements constitute unfair or deceptive trade practices; algorithm distributors who knew or should have known about use of nonpublic competitor data face joint and several liability for antitrust violations
