Some EULA form contracts accompany shrink-wrapped software that is presented to a user sometimes on paper or more usually electronically, during the installation procedure. The user has the choice of accepting or rejecting the agreement. The installation of the software is conditional to the user clicking a button labelled "accept".
Many EULAs assert extensive liability limitations. Most commonly, an EULA will attempt to hold harmless the software licensor in the event that the software causes damage to the user's computer or data, but some software also proposes limitations on whether the licensor can be held liable for damage that arises through improper use of the software (for example, incorrectly using tax preparation software and incurring penalties as a result). One case upholding such limitations on consequential damages is M.A. Mortenson Co. v. Timberline Software Corp., et al. Some EULAs also claim restrictions on venue and applicable law in the event that a legal dispute arises.
Some copyright owners use EULAs in an effort to circumvent limitations the applicable copyright law places on their copyrights (such as the limitations in sections 107–122 of the United States Copyright Act), or to expand the scope of control over the work into areas for which copyright protection is denied by law (such as attempting to charge for, regulate or prevent private performances of a work beyond a certain number of performances or beyond a certain period of time). Such EULAs are, in essence, efforts to gain control, by contract, over matters upon which copyright law precludes control.  This kind of EULAs concurs in aim with DRM and both may be used as alternate methods for widening control over software.
In disputes of this nature in the United States, cases are often appealed and different circuit courts of appeal sometimes disagree about these clauses. This provides an opportunity for the U.S. Supreme Court to intervene, which it has usually done in a scope-limited and cautious manner, providing little in the way of precedent or settled law
