A copyright owner has the exclusive rights to reproduce, adapt, publish, perform, and display their original work. Copyright infringement is the copying, distributing, or displaying of an original work without the owner's permission — any one of these acts, if done without authorization, can constitute infringement. The legal foundation for copyright protection in the United States is the U.S. Copyright Act, which was initially enacted in 1790 and has been revised over the years. Two significant updates came in 1998: the Sonny Bono Copyright Term Extension Act, which extended the copyright duration for most protected works from 50 to 70 years following the author's death, and the Digital Millennium Copyright Act (DMCA), which was introduced specifically to address digital copyright concerns. TCP Law assists both copyright owners enforcing their rights and parties responding to infringement claims, and offers a free consultation to help evaluate your situation.

A copyright infringement claim requires the plaintiff to demonstrate two things. First, that they own a valid copyright in an original work. Second, that there was actionable copying of the original elements of that work. The actionable copying requirement can be demonstrated in two ways: by showing that the alleged infringer had access to the original work, and by showing that the accused work is substantially similar to the original — which may be established through a side-by-side comparison of the two works. Both elements must be present: ownership of a valid copyright and evidence that the defendant actually copied protected expression from it. Independent creation of a similar work — without any actual copying — is a complete defense to an infringement claim, because copyright protects against copying, not against coincidental similarity.

Copyright infringement damages can be pursued under two distinct frameworks. Actual damages include the profit the copyright owner lost as a result of the infringement — such as a license fee the infringer should have paid — plus any additional profits the infringer received as a result of the infringement. Actual damages must be proven in court and can be difficult to establish, particularly when quantifying lost licensing revenue or attributing an infringer's profits specifically to the infringing activity. Statutory damages are an alternative that avoids this evidentiary burden: the amounts are set by statute at between $750 and $30,000 per infringed work, and can increase to up to $150,000 per work in cases of willful infringement. To qualify for statutory damages, the copyright owner must have registered the work either within three months of its publication or before the infringement began — which is the critical reason why timely registration is so strategically important.

The timing of copyright registration relative to the infringement is one of the most consequential strategic decisions a copyright owner can make. To be eligible for statutory damages — which can reach up to $150,000 per work for willful infringement, without needing to prove actual financial losses — the copyright must have been registered either within three months of the work's first publication or before the infringement began. If infringement starts and you have not yet registered, and the registration was not made within three months of publication, you are limited to pursuing actual damages, which must be proven and can be difficult to quantify. This timing rule is why registering creative works promptly — ideally before any infringement occurs — is so important: it preserves the full range of remedies available to you and puts you in a significantly stronger enforcement position from the outset.

Fair use is a legal doctrine that permits certain uses of copyrighted works without obtaining permission from the copyright owner. The uses specifically recognized as potentially qualifying for fair use include criticism, comment, news reporting, teaching, scholarship, and research. However, fair use is not a blanket permission for any use that falls into these categories — it is a defense that must be evaluated case by case based on the specific facts and circumstances of the use. Whether a particular use qualifies as fair use is determined by weighing a set of statutory factors, and the result is never automatically guaranteed simply because the use involves one of the listed categories. A commentary that reproduces an entire work, for example, is far less likely to qualify as fair use than one that quotes briefly and transformatively.

Determining whether fair use applies involves evaluating four factors: the purpose and character of the use; the nature of the copyrighted work; the amount and substantiality of the portion used; and the effect of the use on the potential market and value of the copyrighted work. No single factor is determinative — courts weigh all four together in light of the specific facts of the case. The purpose and character factor often focuses on whether the use is transformative, meaning it adds new meaning, expression, or message rather than simply reproducing the original. The effect on the market is frequently treated as particularly significant because copyright law is fundamentally concerned with protecting the economic value of creative works. Because fair use is inherently fact-specific, consulting an IP attorney before relying on it as a justification for using someone else's copyrighted material is strongly advisable.

There are three primary defenses to a copyright infringement claim. Fair use — as discussed above — permits certain uses of copyrighted material without permission based on a multi-factor analysis. Independent creation is a complete defense: if you created your work without any actionable copying of the plaintiff's work — meaning you developed it independently, without access to or copying of the original — there is no infringement, even if the works are similar. The statute of limitations is the third defense: a copyright owner must file a copyright infringement suit within three years of the date they knew or reasonably should have known of the infringement. If a claim is brought after this three-year window has passed, it may be time-barred regardless of the merits. TCP Law assists clients in evaluating the strength of both infringement claims and defenses, and offers a free consultation to help you understand your position.

Actionable copying is the second required element of a copyright infringement claim, and it has two components. The first is access — evidence that the alleged infringer had an opportunity to see or hear the original work before creating the accused work. The second is substantial similarity — a showing that the accused work is sufficiently similar to the original that a reasonable person would conclude the protected expression was copied. Substantial similarity may be demonstrated through a side-by-side comparison of the two works, examining whether the protectable creative elements — not just the underlying ideas or facts, which are not copyrightable — are reproduced in the accused work. The threshold for substantial similarity is not an exact copy: reproducing the overall structure, sequence, or distinctive creative expression of a work can satisfy the standard even if individual words or elements have been altered.

The Digital Millennium Copyright Act (DMCA), enacted in 1998, was introduced specifically to address copyright concerns arising from the internet and digital technology. Among its key provisions is a notice-and-takedown system that allows copyright owners to request the removal of infringing content from online platforms — when a copyright owner submits a properly formatted DMCA notice to a platform's designated copyright agent, the platform is required to remove the content promptly to maintain its safe harbor protection from infringement liability. This mechanism is widely used against unauthorized posting of photographs, videos, written content, music, and software on platforms including social media sites, e-commerce marketplaces, and content hosting services. While DMCA takedowns are a practical and relatively fast enforcement tool, they work most effectively in combination with a registered copyright, which strengthens the owner's position if the accused party files a counter-notice disputing the takedown.

Yes — this is one of the most widely misunderstood aspects of copyright law. Non-commercial purpose and educational context are relevant considerations under the fair use analysis, but neither one automatically qualifies a use as fair use. Fair use is determined by weighing all four statutory factors together — purpose and character of the use, nature of the copyrighted work, amount and substantiality of the portion used, and effect on the market for the original work — and no single factor is independently decisive. A non-commercial educational use that reproduces an entire work and substitutes for the market for the original is far less likely to qualify as fair use than a brief, transformative quotation used in critical commentary, regardless of the educational intent. Relying on non-commercial or educational purpose as an assumed shield against infringement liability, without a proper legal analysis, exposes individuals and institutions to real and significant legal risk.
