1. What is Fair Use?

In essence, fair use is a limitation on the exclusive rights of copyright holders. The Copyright Act gives copyright holders the exclusive right to reproduce works for a limited time period. Fair use is a limitation on this right. A use which is considered "fair" does not infringe copyright, even if it involves one of the exclusive rights of copyright holders. Fair use allows consumers to make a copy of part or all of a copyrighted work, even where the copyright holder has not given permission or objects to your use of the work.

3. How Do You Know If It's Fair Use?

There are no clear-cut rules for deciding what's fair use and there are no "automatic" classes of fair uses. Fair use is decided by a judge, on a case by case basis, after balancing the four factors listed in section 107 of the Copyright statute. The factors to be considered include:

1. The purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes -- Courts are more likely to find fair use where the use is for noncommercial purposes.
2. The nature of the copyrighted work -- A particular use is more likely to be fair where the copied work is factual rather than creative.
3. The amount and substantiality of the portion used in relation to the copyrighted work as a whole -- A court will balance this factor toward a finding of fair use where the amount taken is small or insignificant in proportion to the overall work.
4. The effect of the use upon the potential market for or value of the copyrighted work -- If the court finds the newly created work is not a substitute product for the copyrighted work, it will be more likely to weigh this factor in favor of fair use.

4. What's been recognized as fair use?

Courts have previously found that a use was fair where the use of the copyrighted work was socially beneficial. In particular, U.S. courts have recognized the following fair uses: criticism, comment, news reporting, teaching, scholarship, research and parodies.
