End User License Agreement (EULA)
A form license agreement governing the rights of an end user to install, access, and use a software product. Typically a non-negotiated take-it-or-leave-it contract delivered through click-wrap, shrink-wrap, or in-application acceptance. Distinct from the negotiated software license agreement used in commercial transactions.
An End User License Agreement (EULA) is a form license agreement governing the rights of an individual end user to install, access, and use a software product. EULAs are typically non-negotiated, take-it-or-leave-it contracts delivered through click-wrap acceptance, shrink-wrap packaging, or in-application acceptance prompts. They are the consumer-facing analog of the negotiated commercial software license agreement.
Typical EULA terms
A standard EULA grants a non-exclusive, non-transferable, revocable license to install and use the software for internal purposes only. Common restrictions include prohibitions on (1) reverse engineering, decompiling, or disassembling; (2) sublicensing or redistribution; (3) removal of proprietary notices; (4) use beyond the licensed seat or device count; and (5) commercial use of consumer-licensed software. Many EULAs provide that the license terminates automatically on breach.
Enforceability
EULAs delivered as click-wrap (with affirmative user assent before installation or first use) are generally enforceable in Texas. Browsewrap-style EULAs accessible only through hyperlink without affirmative user action face serious enforcement challenges. Some courts have enforced shrink-wrap EULAs (terms inside the package, accepted by opening or installing) where the packaging disclosed that additional terms applied, but enforceability is less settled than for click-wrap.
Limits on enforceability
Enforceable EULAs still operate within outside limits. (1) The archival and essential-step copying rights in 17 U.S.C. § 117 belong to the "owner of a copy" of a program, and a license can make that status contestable. (2) For a consumer, a waiver of DTPA rights is void unless it meets the conditions of Tex. Bus. & Com. Code § 17.42, although implied warranties arising under Chapter 2, where it applies, can be disclaimed by conspicuous language under § 2.316. (3) General contract defenses such as unconscionability remain available, subject to the Federal Arbitration Act where the clause is an arbitration agreement, including a class-action waiver within one. A business buyer can be a DTPA consumer unless it falls within the $25 million asset exclusion in § 17.45(4) or an exemption in § 17.49.
Courts deciding whether a EULA binds a user look at how the terms were presented, whether the user had a reasonable opportunity to review them, and whether the vendor can prove assent. Later changes to the terms raise the same assent questions. EULAs distributed through enterprise sales channels are typically replaced or supplemented by a negotiated Software License Agreement.
