Licensing Agreement
A Licensing Agreement is a document used by the owner of some form of intellectual property - such as a logo, photograph, or song - to give permission to some other individual to use that property. The Agreement outlines how the Licensor (the Party who owns the property) will grant the license to use their property to the Licensee (the Party who is using the Licensor's property). This type of Agreement is used in situations where the creator of intellectual property is okay with someone else using their property but wishes to ultimately retain their rights to the property and be compensated in exchange for giving the license. This is different than an Intellectual Property Release wherein the owner of the property gives away all of their rights to the work and does not receive continued compensation, known as royalty payments, in exchange for giving permission.
By using a Licensing Agreement, the owner of intellectual property is able to make money while also controlling how their property is used and disseminated out in the world. Further, individuals being granted a license can use other people's intellectual property to grow their own business or make a living while protecting themselves from intellectual property infringement claims by defining the terms of the property's use.
End-User License Agreement
An End-User License Agreement, or EULA, as it is often called, is a document through which a creator/owner of software broadly licenses the software for online users. Most often, EULAs are provided in the context of software for sale online, but sometimes, individuals or companies that share their software for free also govern the provision of that software through EULAs.
For any creator/owner of software wishing to share that software with the public, a EULA is a good idea, as it allows the owner to dictate the terms on which that software is shared. The software doesn't have to be a large, complex program; it can be any piece of software which is provided for the public.
The EULA document on any website or mobile app creates a legally binding set of rules for the user on how the software can be used and shared (if applicable). A well-written EULA will also cover items that are absolutely not permitted regarding the software, such as reverse assembly or security breaches.
This document is different than a Licensing Agreement. There, any type of intellectual property can be licensed, like a copyright or trademark, and that document is between two specific parties, the Licensor and the Licensee. This is in contrast to a EULA, where the owner of the software is licensing it for general public use.
Notice for Non-Renewal of Contract
A Notice for Non-Renewal of Contract is a document through which one party permanently ends a contractual relationship with another party. These documents are used in situations where the parties have entered a contract which may have a "rolling" renewal - in other words, an assumed or automatic renewal. This document will allow the party wishing to terminate the relationship to send an official notice.
Many times, in business relationships, parties will have fixed contract terms that are expected to renew. The only way to ensure that the contract doesn't renew is to send this kind of written notification.
