Whether a shrinkwrap software license, disclosed after purchase but before use and accompanied by a right to return the product, can form an enforceable contract under Wisconsin law and the Uniform Commercial Code.
Holding
Yes. ProCD validly proposed that use of the software after an opportunity to review the license would constitute acceptance, and Zeidenberg accepted by using the software without returning it.
Reasoning
The court rejected the premise that a retail contract must be complete when the buyer pays at the register. Under UCC § 2-204(1), a sales contract may be formed in any manner sufficient to show agreement. As master of the offer, a seller may specify the conduct that counts as acceptance; ProCD specified that the buyer could review the license and accept it by using the software.
ProCD gave buyers reasonable notice that the product was subject to an enclosed license, made the terms available in the manual, on the discs, and on the computer screen, and gave buyers the option to return the package for a refund. Zeidenberg had an opportunity to inspect the terms, was required to indicate acceptance to proceed with the program, and continued to use the product. His conduct therefore manifested assent.
The court analogized shrinkwrap terms to familiar transactions in which payment precedes receipt and review of full terms: insurance policies, airline tickets, concert tickets, product warranties, and drug-package inserts. Requiring all terms to appear on the outside of a software box would be impractical and would needlessly raise transaction costs, especially for software sold by mail, telephone, or electronic transmission.
UCC provisions requiring special prominence or signatures for particular terms, such as warranty disclaimers and no-oral-modification clauses, imply that ordinary terms need not satisfy those heightened requirements. UCC § 2-606 also supports the commercial importance of allowing buyers to inspect delivered goods and reject them if the terms are unacceptable. No Wisconsin authority required ordinary shrinkwrap terms to be displayed on the box exterior.
The court also emphasized that the license was not an unexpected post-sale demand for additional payment. It was part of the product ProCD offered, including its price and permitted uses. Absent a generally applicable contract defense, such as illegality or unconscionability, courts should enforce those terms rather than revise the parties' bargain. Zeidenberg did not contend that the noncommercial-use restriction was substantively objectionable.
