What Is Substantial Alteration of a Copyright Infringment?

By Angela Floyd

When someone takes your original song, or your book, movie or film, and uses it without your permission, copyright infringement occurs. The infringer may just copy your original work outright or may create something similar to your work but altered. When two works are similar, but not identical, it can be difficult to distinguish permissible versus impermissible copying. Can you recognize your work in the second work? If so, are the two works substantially similar to the point of infringement? Or, is the new work so substantially altered that a new and valuable work has been created?

Copyright Elements

Under U.S. copyright law, you have a copyright as soon as you make a fixed, tangible copy of your original work. Copyright protection extends to all original ideas and expressive elements of the work. In the case of a book, expressive elements include plot devices, setting, tension and characters. In the case of a song, they can include the lyrics, the arrangement, the notes, even the voice.

Infringement

If you register your copyright, you get additional rights, including the statutory damages and the award of attorney fees should you hire an attorney to enforce your rights against an infringer. Both of these rights give you tools to protect your work, both ideas and expressive elements, against unauthorized copying or alterations. When two works are similar, or one work incorporates pieces of another, infringement generally turns on the question of whether the whole or parts of the second work are "substantially similar" to the original or whether the whole or parts of the original work has been substantially altered.

Substantially Similar

Under the "fair use" doctrine of U.S. copyright laws, others may use limited portions of your work, such as short quotations, without your permission for purposes including book reviews, classroom lessons or news reports. U.S. copyright law also permits some trivial similarities between two works. If there is substantial similarity, however, in whole or part, between the works, then the copying is generally impermissible. If the second work is not substantially similar and has been substantially altered, then the copying may be deemed permissible. Keep in mind, what constitutes originality, substantial similarity and substantial alteration is not always clear.

Substantial Alteration

Substantial alteration means generally that the original, creative expression of your work has been changed enough to create a new, valuable, non-infringing work. Substantial alteration goes beyond how much of the second work is original or how much of the original has been copied. Think about what makes your song or movie original, memorable and distinguishable. Has that been changed in the new work or not? In the case of music, the most original or “meritorious” parts can be quite brief, so infringement may be found even where only a small part is copied without any substantial alteration.

Is an Original Work Without a Copyright Label or Disclaimer Still Protected by Copyright Laws?

Copyright infringement can carry civil and criminal penalties, and many people mistakenly believe that items are copyrighted only when there is a copyright symbol or when the copyrights are registered with the U.S. Copyright Office. However, copyrights are automatic, and creators do not have to use a copyright symbol or register their creations in order to obtain copyright protection.

Is Copyright Violation a Crime?

The term, copyright refers to rights of ownership afforded to the authors of original works and the protection of those rights. A “work” is defined as intellectual property that is published or unpublished, including musical, artistic, literary and dramatic works. In short, it means that only the person who created the work has a legal right to distribute it in any form to make a profit. Willful copyright violation, or copyright infringement, is the act of violating any of a copyright owner's exclusive rights; it is a crime.

The Right to Sell Copyrighted Material

A copyright is a bundle of rights that includes a legal monopoly on the right to sell a particular work of authorship. If you wish to sell material copyrighted by someone else, or to sell a work that incorporates such material, you might be able to rely on one of two strategies: either take advantage of exceptions to copyright protection or obtain permission from the copyright holder.
