What is the difference between copyright infringement and plagiarism?

Copyright infringement is a legal violation of the exclusive rights granted to copyright owners under 17 U.S.C. 106 - it's actionable in federal court with statutory damages up to $150,000 per work. Plagiarism is an ethical violation involving passing off someone else's work as your own, without proper attribution. Plagiarism may not always be copyright infringement (e.g., plagiarizing public domain works), and infringement doesn't require plagiarism (e.g., unauthorized copying with attribution is still infringement). However, most plagiarism of copyrighted works is also infringement.

What is fair use and when does it apply?

Fair use (17 U.S.C. 107) is a defense to copyright infringement allowing limited use for purposes such as criticism, comment, news reporting, teaching, scholarship, or research. Courts analyze four factors: (1) purpose and character of use (transformative? commercial?), (2) nature of the copyrighted work (factual vs. creative), (3) amount and substantiality used, and (4) effect on the market for the original. No single factor is determinative, and fair use is decided case-by-case. Common misconceptions: there's no bright-line rule for word count, non-commercial use isn't automatically fair use, and giving credit doesn't make it fair use.

Who owns the copyright in a book - the author or publisher?

Initially, the author owns the copyright in their work. Through publishing agreements, authors typically license certain rights to publishers (print, digital, audio, foreign) while retaining copyright ownership. Some contracts require copyright assignment to the publisher. Work-for-hire agreements (common for ghostwriting) mean the hiring party owns copyright from creation. To know who can enforce rights, review the publishing contract carefully. Authors often retain the right to pursue infringement of unlicensed rights.

Can AI companies use my books to train their models without permission?

This is an emerging and contested legal issue. Multiple class action lawsuits (Authors Guild v. OpenAI, Tremblay v. OpenAI, Silverman v. Meta) argue that training AI on copyrighted books without permission is infringement. AI companies claim fair use. No definitive court ruling exists yet. If your work was used for AI training without permission, you may have claims for copyright infringement. Consider joining existing class actions or filing individual claims, especially for registered works.

What damages can I recover for book piracy?

For registered works, you can elect statutory damages of $750-$30,000 per work, up to $150,000 for willful infringement, plus attorney fees. For unregistered works (or works registered after infringement), you're limited to actual damages (lost sales, lost royalties) plus the infringer's profits attributable to the infringement. Actual damages require proof of harm, while statutory damages are available simply by proving infringement. This makes timely registration critical for authors.

Is posting quotes from books on social media copyright infringement?

It depends on the circumstances. Brief quotes for purposes of criticism, commentary, or review often qualify as fair use. However, posting substantial excerpts, especially without commentary or for commercial purposes (driving traffic to monetized content), may be infringement. Posting entire chapters or significant portions is almost certainly infringement. The key factors are: how much is quoted relative to the whole work, whether the quote substitutes for purchasing the book, and whether the use is transformative.

Literary Works & Publishing Copyright Infringement Demand Letters

Literary Copyright Framework

Literary Works Defined: Under copyright law, "literary works" include novels, short stories, poems, articles, blog posts, essays, textbooks, manuals, scripts, and other works expressed in words, numbers, or symbols. Protection is automatic upon creation - no registration required for protection to exist, though registration is essential for enforcement.

What Literary Copyright Protects

Protected	Not Protected
Specific expression of ideas (exact words, sentences, structure)	Ideas, facts, concepts, discoveries
Plot, characters (if sufficiently developed), dialogue	Stock characters, generic plot elements, scenes a faire
Selection and arrangement of facts (compilations)	Individual facts themselves
Original translations	Titles, names, short phrases (may be trademark)
Revised editions with new material	Works in the public domain

Copyright vs. Plagiarism

Copyright Infringement:

Legal violation of 17 U.S.C. 106
Actionable in federal court
Statutory damages up to $150,000
Doesn't require claiming authorship
Attribution is not a defense

Plagiarism:

Ethical violation (passing off as own work)
Academic/professional consequences
No direct legal remedy
Can occur with public domain works
Attribution can cure plagiarism

Publisher vs. Author Rights

Scenario	Who Owns Copyright	Who Can Enforce
Self-published	Author	Author
Traditional publishing (license)	Author (licensed rights to publisher)	Usually both, per contract
Copyright assignment	Publisher	Publisher
Work for hire (ghostwriting)	Hiring party from creation	Hiring party
Freelance articles (no contract)	Author	Author

Review Your Publishing Contract: Publishing agreements vary widely in how they allocate rights and enforcement authority. Some contracts require the publisher to pursue infringement; others allow the author to act. Exclusive licensees may have standing to sue in their own name. Always review your contract before sending demand letters.

Fair Use Analysis

17 U.S.C. 107 - Fair Use: Fair use is a defense (not a right) that permits limited use of copyrighted works for purposes such as criticism, comment, news reporting, teaching, scholarship, or research. It's determined case-by-case based on four factors - no bright-line rules exist.

The Four Fair Use Factors

Factor 1: Purpose & Character

Is the use transformative (adding new meaning/purpose)? Commercial or nonprofit educational? Criticism, commentary, parody, or mere copying?

Factor 2: Nature of Work

Is the original factual or creative? Published or unpublished? More protection for creative, unpublished works.

Factor 3: Amount Used

How much was taken in quantity and quality? Was the "heart" of the work copied? Less is generally better, but even small amounts can infringe.

Factor 4: Market Effect

Does the use harm the market for or value of the original? Does it substitute for sales or licensing? Often the most important factor.

Fair Use in Literary Works - Common Scenarios

Use	Likely Fair Use?	Key Considerations
Book review with quotes	Usually yes	Brief quotes for criticism/commentary; transformative purpose
Academic quotation with analysis	Usually yes	Educational purpose; limited amount; doesn't replace original
Posting full chapters online	Usually no	Substantial amount; replaces need to purchase; market harm
Parody of writing style	Often yes	Must comment on original; can't just use as vehicle
News reporting with excerpts	Often yes	Must be newsworthy; limited amount; attribution helps
AI training on copyrighted books	Contested	Major pending litigation; no clear precedent yet

Common Fair Use Myths:

Myth: "I can use X words/pages safely" - No bright-line word limit exists
Myth: "Non-commercial use is always fair" - Commercial nature is one factor, not determinative
Myth: "Giving credit makes it fair use" - Attribution doesn't create fair use
Myth: "Educational use is always fair" - Must still satisfy four-factor test
Myth: "If I transform it, it's fair use" - Transformation is important but not the only factor

AI Training & Literary Works

Emerging Legal Battleground: Multiple lawsuits are challenging AI companies' use of copyrighted books for training. Authors Guild v. OpenAI, Tremblay v. OpenAI, and Silverman v. Meta allege that training AI on copyrighted works without permission constitutes infringement. These cases will define copyright law's application to AI.

Key Issues in AI Training Disputes

Reproduction: Training requires copying works into AI systems - is this infringing reproduction?
Fair Use Defense: AI companies claim training is transformative fair use; authors disagree
Output Liability: When AI generates text similar to training data, who is liable?
Opt-Out Mechanisms: Some AI companies now offer opt-out; does prior training infringe?
Class Action Status: Most cases proceeding as class actions on behalf of affected authors

What Authors Can Do Now

Register copyrights: Essential for statutory damages if you later sue
Join class actions: Monitor Authors Guild and similar organizations for case updates
Use robots.txt: Block AI crawlers from accessing your content online
Opt-out programs: Use AI company opt-out mechanisms where available
Document usage: Track evidence that your works appear in AI outputs
Consider individual claims: Registered works may support individual suits

Frequently Asked Questions

There is no safe word count or percentage. Fair use depends on context: a short quote might infringe if it's the "heart" of the work, while a longer quote for genuine criticism might be permitted. Generally, brief quotes for purposes of review, criticism, commentary, or scholarship are more likely to be fair use. Quoting for mere decoration, entertainment, or to avoid having to write your own content is less likely to qualify. When in doubt, seek permission or consult an attorney.

First, document the infringement with screenshots showing both versions and dates. If the copy is on a website, you can send a DMCA takedown notice to the hosting provider or platform. You can also send a cease and desist letter directly to the infringer demanding removal and compensation. For significant infringement, register your copyright (you can register after infringement, though you'll only get actual damages) and consider filing a federal lawsuit. Many blog infringement cases settle for modest amounts if the infringer is identifiable and has assets.

Copyright requires "substantial similarity" in protected expression - not just ideas. If someone paraphrases your work or takes your structure/sequence without copying verbatim, you may still have a claim if the total concept and feel is substantially similar. However, ideas, facts, and common expressions are not protected. For fiction, protected elements include original plot, developed characters, and distinctive dialogue. For non-fiction, protection is thinner, but original selection/arrangement of facts can be protected. A detailed analysis by a copyright attorney is recommended.

It depends on your publishing contract. If you assigned copyright to the publisher, the copyright becomes a bankruptcy estate asset and may be sold to another party. If you only licensed rights, you may be able to terminate the license (check your contract for reversion clauses triggered by bankruptcy or cessation of publication). The bankruptcy trustee controls the publisher's assets during proceedings. Authors should file a proof of claim in the bankruptcy case and seek to recover their rights. An intellectual property attorney experienced in bankruptcy can help navigate this complex situation.

This is an evolving area of law. If an AI outputs text that is substantially similar to your copyrighted work, there may be infringement claims against the AI company (for training on your work) and potentially against users who publish the infringing output. Key questions courts are considering: Is the AI output a "copy" or an independent creation? Does substantial similarity in output prove copying during training? Who is liable - the AI company, the user, or both? Document any AI outputs that closely match your work and consult an attorney about your options.

The Copyright Office offers group registration options for certain works. For short online literary works (blog posts, articles under 17,500 words), you can register up to 50 works published within a 3-month period for a single fee using form GRUW. For longer works or works published over a longer period, you may need individual registrations. All works in a group registration must be by the same author. Group registration is cost-effective for prolific bloggers and journalists - one $65 fee versus $65 per individual work.
