Definition of copyright
Copyright protects original works of authorship—writing, software source code, music, photos, video, and more—once they are fixed in a tangible form. It is a limited-time exclusive right, not ownership of ideas themselves. For how long protection lasts, see copyright duration by country.
Protection Matrix: What Copyright Protects vs Excludes
| Subject Matter Tier | Legal Protection Status | Typical Assets Covered | Core Legal Threshold |
|---|---|---|---|
| 1. Fixed Creative Expressions | Fully Protected | Articles, source code, photos, graphics, video productions. | Originality and fixation in a tangible digital/physical medium. |
| 2. Ideas, Facts & Algorithms | Not Protected | Math formulas, news facts, raw datasets, business workflows. | Idea-Expression Dichotomy prevents monopolization of knowledge. |
| 3. Public Domain Works | Free for All Use | Expired historical works, US Federal Government publications. | Post-mortem term expiration (Life + 70 years) or statutory release. |
| 4. Pure AI-Generated Outputs | Special Threshold | Midjourney renders, raw automated LLM text outputs. | Requires substantial human creative steering and curation. |
The L.E.G.A.L™ Copyright Protection & Defense Standard
- L — Literal Fixation: Mandatory recording of expression in tangible media (code repositories, server timestamps, media files).
- E — Exclusive Economic Rights: Full control over copying, public performance, distribution, and derivative creation.
- G — Global Berne Convention: Reciprocal automatic protection across 181 treaty member jurisdictions.
- A — Automatic Protection vs Formalities: Rights exist upon creation, while US Copyright Office registration unlocks statutory damages.
- L — Limitations & Fair Use: Critical affirmative defenses protecting commentary, news reporting, parody, and education.
What copyright protects
- Literary and textual works (including many websites and documentation)
- Musical works and, separately in many systems, sound recordings
- Dramatic, choreographic, pictorial, graphic, and sculptural works
- Audiovisual works and motion pictures
- Architectural works (where recognized)
- Software as a literary work in most modern systems
Works not protected by copyright
Classic examples of unprotected subject matter include pure ideas, facts, methods of operation, blank forms with no original expression, and short phrases or titles standing alone. Works already in the public domain are free of copyright restrictions (other laws may still apply). False claims over public domain material relate to copyfraud.
Fixation requirement
In systems such as US law, protection generally attaches when original expression is fixed in a tangible medium—written, recorded, saved to disk, or otherwise embodied long enough to be perceived or reproduced. Unfixed improvisation may fall outside copyright until recorded.
Automatic protection vs formalities
Berne members generally do not require registration or notice for protection to arise. Notices (© year owner) and registration still matter strategically—especially in the US for litigation posture. See copyright notice and registration.
Berne Convention (overview)
The Berne Convention coordinates minimum standards and national treatment among member states. It is why foreign works often receive protection without local formalities. Treaty membership lists change; cite WIPO’s live treaty database rather than outdated mirrors.
Copyright vs DMCA procedures
Copyright answers “who owns exclusive rights, for how long?” The DMCA’s notice-and-takedown rules answer “how do online service providers handle infringement claims?” A platform removal is not a court judgment on ownership.

If your copyrighted work has been stolen or republished without permission, you can enforce removal through our full-service DMCA takedown service (delisting from Google and web hosts in 24–48h) or draft a formal notice using our free DMCA takedown notice generator. For high-stakes multi-host disputes, you can book a case consultation with a Designated Agent.
FAQ
What is copyright in simple terms?
Copyright is a set of exclusive legal rights that let creators (or right holders) control how original works of authorship are copied, distributed, displayed, performed, or adapted for a limited time.
What is not protected by copyright?
Ideas, procedures, methods, systems, facts, titles alone, and works not fixed in a tangible medium of expression are generally outside copyright. Public domain works are no longer under copyright (or never were).
Do I need to register copyright to be protected?
In Berne countries, protection is automatic when requirements are met. In the United States, registration is not required for protection to exist, but it is often required before filing a civil infringement lawsuit and affects available remedies.
