Copyright law, designed to protect original works of authorship, specifically does not protect certain types of material that are considered fundamental building blocks of knowledge or functionality rather than unique expressions.
Understanding Copyright's Limits
While copyright protects the tangible expression of an idea, it explicitly excludes the underlying elements that are not considered creative or original in themselves. Specifically, copyright does not protect facts, ideas, systems, or methods of operation. However, it is crucial to understand that while these elements themselves cannot be copyrighted, the unique way in which they are expressed can be protected.
Categories of Uncopyrightable Material
Several categories of material generally fall outside the scope of copyright protection:
- Facts: Individual facts, whether historical, scientific, or statistical, cannot be copyrighted. Facts are discovered, not created, and are considered part of the public domain for everyone to use. For example, the date of a historical event, a mathematical formula, or the ingredients in a standard recipe are not copyrightable.
- Ideas: An idea, concept, or principle itself is not copyrightable. Copyright protects the expression of an idea, not the idea itself. For instance, the idea for a science fiction story about time travel cannot be copyrighted, but the specific plot, characters, and dialogue of a novel based on that idea can be.
- Systems or Methods of Operation: Procedures, processes, systems, methods, concepts, principles, or discoveries are not eligible for copyright protection. This ensures that essential ways of doing things or operating systems remain freely available for innovation and use. Examples include the rules for a game, a method for organizing data, or an accounting system.
- Commonly Known Information: Things that are common property and contain no original authorship, such as standard calendars, height and weight charts, or public domain materials, cannot be copyrighted.
- Titles, Names, Short Phrases, and Slogans: These are generally too short or common to meet the minimum threshold of originality required for copyright protection. While not copyrightable, they might be protectable under trademark law if they are used to identify the source of goods or services.
- Works Lacking Originality: Works that are merely lists of ingredients, standard forms, or simple designs without any creative authorship are typically not copyrightable.
- Works in the Public Domain: Works whose copyright has expired, or works created by the U.S. government (which are generally not subject to copyright), are in the public domain and can be freely used by anyone.
Why Are These Uncopyrightable?
The rationale behind these exclusions is to foster innovation, knowledge sharing, and competition. If fundamental facts, ideas, or methods could be exclusively owned through copyright, it would severely stifle creativity, progress, and the free exchange of information essential for societal advancement. Copyright's role is to incentivize the creation of original expressions by granting creators exclusive rights to their works for a limited time, while simultaneously ensuring that the building blocks of knowledge remain accessible.
Key Distinctions: Idea vs. Expression
Understanding the difference between an idea and its expression is critical in copyright law.
| Uncopyrightable Element | What it Means | Examples |
|---|---|---|
| Facts | Discoveries, not creations | The specific atomic weight of an element, a list of known constellations |
| Ideas | Concepts, themes, plots | The concept of a streaming service, the general theme of good versus evil in a story |
| Systems/Methods | Procedures, processes, operations | The rules of chess, a recipe's ingredient list, a business model |
| Short Phrases | Common sayings, names, titles | "Hello world!", the title of a movie, a company name |
| Public Domain Works | Works with expired copyright or U.S. government works | Shakespeare's plays, federal government reports, common symbols |
While you cannot copyright the idea of a social media platform, you can copyright the specific source code, design, and user interface you create for your particular platform. Similarly, you cannot copyright a dance step, but you can copyright the specific choreography of an entire dance routine.
