Skype and other websites offer End User License Agreement (EULA) contracts which must be signed by users before they begin using some kind of online or otherwise digitally-created service. As such, the user of a website or a software product will agree to the provider’s requirements, as set forth in the End User License Agreement (EULA), as to how the service can permissibly be used and under what conditions.
Moreover, the End User License Agreement (EULA) can be expected to delineate the rights accordingly provided to the user of the good or service. For one, the particular company’s End User License Agreement (EULA) may also contain details as to how the service or product can be used according to the first sale doctrine. This legal principle sets forth limits on how widely copyright be understood to control the subsequent behavior of purchasers.
