ProCD, Inc. v. Zeidenburg, 86 F.3d 1447 (7th Cir. 1996)

– User bought a personal copy of the software, which was priced lower than the commercial version, and resold it to commercial users, in violation of the terms of the enclosed shrinkwrap license.

  • The license restricted sales of personal copies and gave the user the right to return the software if unsatisfied.

– Court upheld the enforceability of the license based on UCC Section 2-206, which provides that a purchaser of goods has the right to review a product, including the terms of the license for the product, and if they are not happy with it they can return it.

  • If they choose to use it and not return it they are bound by the purchase and terms of the license.
