yes, i am looking for a definition for both.

The difference between infringing use and non-infringing use lies in whether the use of a copyrighted work violates the exclusive rights of the copyright holder or falls within the realm of permissible use.

To understand the difference, we need to look at copyright law. Copyright grants certain exclusive rights to the copyright holder, including the right to reproduce, distribute, publicly display or perform, and make derivative works of a copyrighted work.

Infringing use refers to any use of a copyrighted work that violates any of these exclusive rights without obtaining permission from the copyright holder or falling under a legal exception. If someone uses a copyrighted work without the appropriate permission or without meeting the criteria of a legal exception, it may be considered infringing use. For example, reproducing a book without authorization from the author or publisher would likely be considered infringing.

On the other hand, non-infringing use refers to the use of a copyrighted work that is allowed under copyright law or falls under a legal exception. There are several situations where use of a copyrighted work can be considered non-infringing. These include:

1. Fair use: Fair use is a legal doctrine that allows the use of copyrighted works without permission from the copyright holder under certain circumstances. Examples of fair use may include using a small portion of a copyrighted work for criticism, comment, news reporting, teaching, scholarship, or research.

2. Public domain: When a copyright term expires or the copyright holder voluntarily places the work into the public domain, anyone can use, share, or modify the work without infringing copyright.

3. Licensed use: If someone obtains the necessary licenses or permissions from the copyright holder, they can use the work in accordance with the terms and conditions specified in the license.

Determining whether a particular use is infringing or non-infringing can be complex and depends on various factors, such as the purpose and character of the use, the nature of the copyrighted work, the amount used, and the effect on the market for the original work. It often requires a legal analysis specific to the situation.

So, to ascertain whether a specific use is infringing or non-infringing, it's essential to consider the applicable copyright laws, including any exceptions or limitations, and potentially consult legal advice if necessary.
