Fair Use: The Four Factors Courts Consider in a Copyright Infringement Case

Courts use these factors to determine fair use.

Fair use is one of the most common defenses to the claim of copyright infringement. Normally, copyright gives creators certain exclusive rights over their creations, whether books or movies or paintings. Under certain circumstances, however, the use of copyrighted materials is deemed to be excusable when the infringer's use is a "fair" one. When will courts consider a particular use to be "fair"?

How Is Fair Use Determined?

A determination of fair use usually occurs during a copyright infringement suit. A party accused of infringement argues that the infringement is excused under the fair use doctrine.

A court, faced with this argument, weighs four factors and, if the weight of the factors is in favor of the defendant, declares that the unauthorized use of the material is permitted. In order to guide judges in making determinations of fair use, the drafters of the Copyright Act of 1976 included four factors:

  • the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes
  • the nature of the copyrighted work
  • the amount of the portion used in relation to the copyrighted work as a whole, and
  • the effect of the use upon the potential market for or value of the copyrighted work.

Although the fourth factor, the effect of the use upon the potential market, used to be considered to be the most important, a more recent decision by the Supreme Court emphasized the first factor and in particular, “transformative” uses that affect the purposes and character of the use.

The drafters of the Copyright Act of 1976 were careful to advise that the fair use doctrine as expressed in Section 107 was intended only as a guideline. Beyond a broad statutory explanation of what fair use is and some of the criteria applicable to it, the courts are free to adapt the doctrine to particular situations on a case-by-case basis. Below is an analysis of the four fair use factors.

1. Purpose and Character of the Use

The first fair use factor refers mainly to the function for which the copied material is being used. Since copyright law favors the encouragement of scholarship, research, education, and commentary, a judge is more likely to make a determination of fair use if the defendant's use is noncommercial, educational, scientific, or historical. However, an educational or scientific use that is for commercial purposes may not be excused by the fair use doctrine.

For example, copying a scientist's statements in a cigarette advertisement or the large scale videotaping of educational programming is not considered fair use. Similarly, the fact that a use is not for profit will not necessarily excuse an infringing use.

In 1995, this first fair use factor was elevated to the most important factor by the U.S. Supreme Court. What was important, stated the high court, was that the purpose and character of the use was transformative—that the alleged infringement made a new statement using the work.

2. Nature of the Copyrighted Work

The second factor in the fair use determination is the nature of the work that's being copied. For example, a court will ordinarily consider whether the work being copied is informational or entertaining in nature. A judge is more likely to find a determination of fair use if material is copied from a factual work, such as a biography, than from a fictional work, such as a novel.

As the Supreme Court stated in Sony Corp. of America v. Universal City Studios, Inc., "copying a news broadcast may have a stronger claim to fair use than copying a motion picture." Why? Because copying from informational works such as scholarly, scientific, or news journals encourages the free spread of ideas and encourages the creation of new scientific or educational works, all of which benefit the public.

In addition, the court will consider whether the work that is copied is published or unpublished. The scope of fair use is narrower with respect to unpublished works because of the author's right to control the first public appearance of his expression. For example, in the case of Salinger v. Random House, a biographer paraphrased portions of letters written by J.D. Salinger. Although the public could read these letters at a university library, Mr. Salinger had never authorized reproduction or publication of the letters. Despite the scholarly purpose of the proposed Salinger biography, the court would not permit the unauthorized paraphrasing of Mr. Salinger's unpublished letters as a fair use.

3. Amount of Copyrighted Work Used

In another case, a court permitted a biographer to quote from six unpublished letters and ten unpublished journal entries of the late novelist Richard Wright. One factor that weighed in favor of the biographer was the amount of the portions that were used.

The court determined that no more than 1% of Mr. Wright's unpublished letters and journal were copied. When considering the amount and substantiality of the portion taken, the court looks at not just the quantity of the material but the quality of the material taken.

For example, the copying of one minute and fifteen seconds of a 72-minute Charlie Chaplin film was considered substantial and was not permitted as a fair use. In certain rare cases, copying of a complete work may be considered as a fair use. For example, the Supreme Court in the Sony case excused the off-the-air copying of complete television programs.

4. Effect of the Use on the Potential Market

The fourth factor in a fair-use determination is the effect of the use on the potential market for the work that was copied. Consideration of this factor is intended to strike a balance between the benefit that the public will derive if the use is permitted and the personal gain that the copyright owner will receive if the use is denied.

A judge must consider the effect on the potential market for the copyrighted work. This consideration goes beyond the past intentions of the author or the means by which the author is currently exploiting the work.

For example, in a case concerning a photograph that was adapted to a wood sculpture, the court recognized the existence of a market for new versions or new uses of the photograph, and determined that the unauthorized use of the photographic image undermined the potential market.

Some uses are not considered to undermine the potential market. Copying a magazine cover for purposes of a comparative advertisement is a fair use because the comparative advertisement does not undermine the sales or need for the featured magazine. No customer would not buy the magazine merely because of the advertisement. Similarly, it was the lack of market damage in the Sony case that convinced the Supreme Court to permit off-air videotaping.

Acknowledging Source Material Is Not Enough

Many people (non-lawyers, that is), believe that the unauthorized use of a copyrighted work is permitted if an acknowledgment is made as to the source. This is not true.

Acknowledgment of source material (such as citing the author or the publication) may be a consideration in a fair use determination, but it will not protect against a claim of infringement. For example, if you record a feature film in a theater and then sell DVDs of that recording, it will not help your case that you acknowledge the copyright owner on the cover of the DVD. It would still be an impermissible infringement.

When in doubt as to the right to use or acknowledge a source, the most prudent course may be to seek permission of the copyright owner.
