15 U.S.C. § 45b
The Act generally makes provisions of form contracts between sellers and individual consumers void from inception if the provisions: (1) prohibit or restrict individuals from reviewing sellers’ goods, services, or conduct; (2) impose penalties or fees on individuals for such reviews; or (3) require individuals to transfer intellectual property rights in such reviews. The Act also bars sellers from offering form contracts with such provisions. The Act contains certain exceptions, including for contract provisions that bar the submission of confidential, private, or unlawful information.
