Florida Prepaid Postsecondary Education Expense Board v. College Savings Bank, 527 U.S. 627 (1999), was a decision by the Supreme Court of the United States relating to the doctrine of sovereign immunity.

Where College Savings Bank was an action brought under the Lanham Act, Florida Prepaid was a concurrent action brought under the Patent and Plant Variety Protection Remedy Clarification Act.

In a 5–4 decision authored by Chief Justice William Rehnquist, the court held that the Act's abrogation of States' sovereign immunity was invalid.

Applying the § 5 test provided in City of Boerne v. Flores, the validity of the Act could not be sustained.

[1] Justice Stephen Breyer, in Active Liberty (Federalism), mentions the case as example of potentially overreaching or counterproductive restriction of federal authority to "create uniform individual remedies under legislation dealing with nationwide problems—for example, private civil damages actions for citizens injured by a state's unlawful use of their intellectual property."
