Can You Copyright a Concept: Patents, Trademarks, and NDAs

No, you cannot copyright a concept. Copyright protects only the specific, tangible expression of an idea — the actual words, images, sounds, or code you create — and never the underlying idea, method, system, or concept itself. Section 102(b) of the Copyright Act draws that line directly: copyright never extends to “any idea, procedure, process, system, method of operation, concept, principle, or discovery,” no matter how it is described or illustrated.1Office of the Law Revision Counsel. 17 U.S. Code 102 – Subject Matter of Copyright: In General So the concept for an app, a TV show premise, a teaching method, or a business model sits entirely outside copyright’s reach. What you can protect is what you actually build from the concept, and other areas of law may cover the concept itself.

Why the Law Refuses to Copyright Ideas

The rule is called the idea-expression dichotomy, and the reason for it is practical. If one person could own the idea of “a detective story set in a dystopian city,” nobody else could write in that space. Ideas are the raw material of creativity, and the law keeps them available to everyone.

The Supreme Court set this boundary in 1879 in Baker v. Selden. Charles Selden had written a book explaining an innovative bookkeeping system. When another publisher produced forms using the same system, Selden’s estate sued. The Court held that the book explaining the system was protected, but the bookkeeping system itself was not. Anyone could use the accounting method as long as they didn’t copy Selden’s specific text.2Justia. Baker v. Selden, 101 U.S. 99 (1879) The Supreme Court reaffirmed the same principle in its 2021 decision in Google v. Oracle: copyrights protect expression, not the ideas behind it.3Ninth Circuit District & Bankruptcy Courts. Ninth Circuit Manual of Model Civil Jury Instructions 17.4 – Copyright Subject Matter Ideas and Expression

A concrete example clarifies the split. The concept of a competitive baking reality show is an unprotectable idea. Ten production companies can develop their own competitive baking shows without any copyright issue. But the actual recorded episodes of a specific show, with its particular host, set, scoring format, and contestant interactions, are protected expression. Same with storytelling: the theme of star-crossed lovers from warring families is an idea as old as literature. Romeo and Juliet, West Side Story, and countless other works all use it, and each one’s specific text and creative choices are independently copyrightable.

What Copyright Actually Covers

Copyright kicks in automatically the moment you fix an original work in a tangible form. Writing it down, recording it, saving a file — any of these count. You don’t need to file paperwork, add a notice, or publish the work for protection to exist.4U.S. Copyright Office. About Copyright Two conditions have to be met: the work has to be independently created (not copied from someone else), and it has to contain at least a minimal spark of creativity.

The categories the Copyright Act lists — literary works, musical works, dramatic works, pictorial and sculptural works, motion pictures, sound recordings, architectural works, choreography — all share a pattern.1Office of the Law Revision Counsel. 17 U.S. Code 102 – Subject Matter of Copyright: In General Every one of them is a finished, tangible product. The novel, not the plot idea. The recording, not the concept for a song. The architectural plans or the building itself, not the notion of a building with a green roof.

One practical footnote on enforcement: while protection is automatic, you cannot file a federal infringement lawsuit over a U.S. work until you’ve registered it with the Copyright Office (or had an application refused).4U.S. Copyright Office.

When Even Expression Loses Protection

Here is where creators often get tripped up. Even original expression can lose copyright protection when the underlying idea can only be expressed in a very limited number of ways. Courts call this the merger doctrine: when idea and expression effectively merge because there’s no other way to say the thing, nobody gets to own that expression either. As one federal decision put it, if an idea “can only be expressed in a limited number of ways, those means of expression cannot be protected, lest one author own the idea itself.”7U.S. Copyright Office. Copyright Office Review Board Decision – ABCD 1-8

The classic example involves a jeweled bee pin. When one jewelry maker sued a competitor over a similar bee-shaped brooch, the court ruled that the idea of a jeweled bee pin and its expression were essentially inseparable. There are only so many ways to make a brooch look like a bee, and granting copyright over one version would hand a single company a monopoly on the concept.

A related principle called scènes à faire excludes stock elements that naturally flow from a genre or setting. A courtroom drama will inevitably feature a judge, a witness stand, opening statements, and cross-examination. A Western will include saloons, gunfights, and dusty main streets. These standard-issue components aren’t copyrightable because they’re expected building blocks of the genre, not any one author’s creative contribution. The more generic or inevitable your expression, the less copyright can do for you.

Legal Tools That Can Protect the Concept Itself

Because copyright is off the table for concepts, other areas of intellectual property law fill different gaps. Each one covers a different kind of asset under different rules.

Patents

Patents are the primary tool for protecting an inventive concept. A utility patent covers a new and useful process, machine, manufactured item, or composition of matter.8Office of the Law Revision Counsel. 35 U.S. Code 101 – Inventions Patentable To qualify, the invention also has to be non-obvious, meaning someone with ordinary skill in the field wouldn’t find it an obvious next step from what already exists.9Office of the Law Revision Counsel. 35 U.S. Code 103 – Conditions for Patentability; Non-obvious Subject Matter That is a far higher bar than copyright’s minimal creativity threshold. The patent process requires a detailed application, examination by the patent office, and often takes years. A utility patent lasts 20 years from the filing date.

A design patent protects something narrower: the ornamental appearance of a functional item rather than how it works. Think the distinctive shape of a chair or the visual layout of a smartphone interface. Design patents last 15 years from the date of grant and protect only the specific visual design shown in the patent drawings.10Office of the Law Revision Counsel. 35 U.S. Code 173 – Term of Design Patent Neither type of patent will protect a bare concept — the invention or design has to be worked out in enough detail to describe and, for a design patent, to be embodied in an actual article of manufacture.

Trademarks

Trademarks protect brand identity: a word, phrase, symbol, design, or combination that identifies where goods or services come from and distinguishes one business from its competitors.11United States Patent and Trademark Office. What Is a Trademark A trademark won’t protect an idea for a product, but it can protect the name, logo, or slogan you use to sell it. Unlike patents and copyrights, trademarks can last indefinitely as long as you keep using the mark in commerce and file the required maintenance documents.

Trade Secrets

Trade secret law protects confidential business information that derives economic value from being kept secret. Formulas, algorithms, customer lists, manufacturing processes, and business methods can all qualify. The Coca-Cola formula is the well-known example, protected for over a century as a trade secret rather than through a patent, which would have expired long ago.

The catch is that trade secret protection requires you to actually keep the information secret. You have to take reasonable measures: restricting access, using confidentiality agreements, marking documents appropriately. If the secret gets out because you failed to protect it, the legal protection disappears. The federal Defend Trade Secrets Act, passed in 2016, gives trade secret owners a path to federal court when their secrets are misappropriated, in addition to whatever state-law remedies exist.

Using NDAs and Contracts Before You Share an Idea

For many creators, the real risk isn’t a stranger independently inventing the same concept. It’s sharing the idea with a potential partner, investor, or studio and watching them run with it. Copyright and patent law may not help here, but contract law can.

A non-disclosure agreement signed before you reveal your concept creates a contractual obligation to keep the information confidential. The NDA doesn’t give you ownership of the idea, but it does give you a legal claim for breach of contract if the other party uses or shares what you told them. The key is getting the NDA signed before any disclosure. Once you’ve shared the idea without a confidentiality agreement in place, you’ve lost most of your leverage.

A workable NDA should clearly define what information is confidential (broad enough to cover oral disclosures and derivative analysis, not just written documents), specify how long the obligation lasts, and identify the consequences of a breach. When you’re the only one sharing sensitive information, a one-way NDA is appropriate. When both sides are exchanging confidential material, as in a potential joint venture, a mutual NDA protects everyone.

Unsolicited Submissions to Large Companies

If you’re pitching an idea to a large company without a prior relationship, expect to run into an unsolicited submission policy. Most major entertainment companies, manufacturers, and tech firms require you to agree to terms before they’ll even look at your concept. Those terms typically state that the company has no confidentiality obligation, can develop similar ideas independently, owes you nothing if it later creates a product resembling your pitch, and receives a broad license to use anything you submit. These policies exist specifically to insulate the company from idea-theft lawsuits.

Some creators have succeeded in court by arguing that an implied contract existed — that the circumstances of the pitch created an unspoken agreement to compensate them if the idea was used. Proving this requires showing a clear offer, acceptance, mutual intent, and something of value exchanged. These cases are difficult to win without strong evidence that the company solicited the idea and the creator expected payment. Written agreements are always more reliable than implied ones.

Who Owns the Expression: Work-for-Hire

Even when your idea becomes a copyrightable expression, you might not be the one who owns it. Under the work-for-hire doctrine, anything an employee creates within the scope of their employment belongs to the employer. The company is treated as the legal author from the start; the employee never holds the copyright at all.

For independent contractors, the rules are narrower. A contractor’s work qualifies as work-for-hire only if it falls into one of several specific categories (contributions to a collective work, translations, compilations, instructional texts, and a few others) and both parties sign a written agreement designating it as such. Without that written agreement, the contractor typically keeps the copyright.

Creators who develop ideas on company time, using company resources, often assume they personally own the resulting work. They usually don’t. If retaining ownership of your creative output matters to you, address it explicitly in your employment or contractor agreement before you start creating.
