Shrink-wrap and Click-wrap Licenses
The term shrink-wrap license refers colloquially to any software license agreement which is enclosed within a software package and is inaccessible to the customer until after purchase. Typically, the license agreement is printed on paper included inside the boxed software. It may also be presented to the user on-screen during installation, in which case the license is sometimes referred to as a click-wrap license. The inability of the customer to review the license agreement before purchasing the software has caused such licenses to run afoul of legal challenges in some cases.
Whether shrink-wrap licenses are legally binding differs between jurisdictions, though a majority of jurisdictions hold such licenses to be enforceable. At particular issue is the difference in opinion between the courts in Klocek v. Gateway and Brower v. Gateway. Both cases involved a shrink-wrapped license document provided by the online vendor of a computer system. The terms of the shrink-wrapped license were not provided at the time of purchase, but were rather included with the shipped product as a printed document. The license required the customer to return the product within a limited time frame if the license was not agreed to. In Brower, New York's state appeals court ruled that the terms of the shrink-wrapped license document were enforceable because the customer's assent was evident by its failure to return the merchandise within the 30 days specified by the document. The U.S. District Court of Kansas in Klocek ruled that the contract of sale was complete at the time of the transaction, and the additional shipped terms contained in a document similar to that in Brower did not constitute a contract, because the customer never agreed to them when the contract of sale was completed.
Further, in ProCD v. Zeidenberg, the license was ruled enforceable because it was necessary for the customer to assent to the terms of the agreement by clicking on an "I Agree" button in order to install the software. In Specht v. Netscape Communications Corp., however, the licensee was able to download and install the software without first being required to review and positively assent to the terms of the agreement, and so the license was held to be unenforceable.
Click-wrap license agreements refer to website based contract formation (see iLan Systems, Inc. v. Netscout Service Level Corp.). A common example of this occurs where a user must affirmatively assent to license terms of a website, by clicking "yes" on a pop-up, in order to access website features. This is therefore analogous to shrink-wrap licenses, where a buyer implied agrees to license terms by first removing the software package's shrink-wrap and then utilizing the software itself. In both types of analysis, focus is on the actions of end user and asks whether there is an explicit or implicit acceptance of the additional licensing terms.
