They Used Your Concept: When Idea Theft Is a Legal Claim, and When It Isn't

You pitched it. They passed. Then they did it themselves. Copyright doesn't protect ideas — but that isn't the end of the analysis, and what you do in the first week matters more than the theory.

They Used Your Concept: When Idea Theft Is a Legal Claim, and When It Isn't

You submitted the proposal. They passed on it, or never replied. Months later, there it is — your concept, running under someone else's name.

It's one of the most common calls creative professionals make to a lawyer, and the honest answer starts with bad news. But the bad news isn't the whole answer, and the people who act carefully in the first week end up in a very different position from the ones who send the angry email. For help with agreements and submissions, see our contracts practice.

The hard part first

Copyright does not protect ideas. It protects expression — the specific way an idea is written, drawn, filmed, or built.

The statute says this outright. Concepts, procedures, methods, and principles are carved out no matter how original they are or how much work went into them. So a company or institution that takes your concept and executes it themselves has often not committed copyright infringement.

That's the answer most people don't want and most need before spending money on the wrong theory.

Where a real claim usually lives

The question isn't "did they use my idea." It's narrower and more useful:

How much of your actual expression shows up in their version?

Your proposal document is protected. The written text, the curatorial or strategic framing, the renderings, diagrams, layouts, images, the specific language. If your sentences, your visuals, or your materials appear in their press release, catalog, deck, or marketing, that's a copyright question and a substantially different conversation.

Put their finished version next to your submission and compare them line by line before deciding you have nothing.

The submission terms decide more than people expect

Almost nobody reads the terms of an open call, RFP, or pitch portal before submitting. They frequently control the outcome.

Some expressly disclaim any rights in what you send. Some grant the organization a broad license to use submitted materials. Some say nothing at all, which is its own answer. Whatever those terms said on the day you applied is the document to find first — not the version on their site today.

The theory that actually reaches concepts

Where copyright stops, contract sometimes continues.

In a number of states, submitting an idea under circumstances where both sides understand it's being offered for consideration can create an implied-in-fact contract — the legal recognition that ideas have commercial value and that using one can require payment. Requirements vary meaningfully by state; some demand that the idea be genuinely novel, and the circumstances of the submission matter a great deal.

A related theory, breach of confidence, can apply where the material was shared in confidence, expressly or by clear implication.

These are the doctrines that reach the thing copyright won't touch. They're also fact-intensive, which is exactly why the record you build early determines whether there's anything to work with later.

What to do, in order

Document before you contact anyone. Your submission with its timestamp, the call or pitch terms as they existed when you applied, every piece of correspondence, and complete captures of their version — announcements, press, catalog, social, wall text. Evidence has a way of being revised once people know someone is looking.

Don't send the email you want to send. It's the most natural move and the most expensive. It can create admissions, waive positions, and hand the other side time to adjust their materials before anyone has preserved them.

Register the copyright in your proposal. Registration is a precondition to filing suit in the United States, and its timing affects what remedies are available. That's worth doing whether or not you ever sue.

Decide what outcome you actually want. This matters more than which theory is strongest. Credit and a fee is a very different ask than damages — and in reputation-driven industries it is often faster, cheaper, and more achievable. A letter seeking attribution and a curatorial or consulting fee lands differently than a complaint, and it leaves a bridge standing.

The prevention is the real lesson

Read the submission terms before you send anything. Pitch at the altitude that wins the opportunity and hold the granular execution for the conversation after they say yes. Mark submissions as confidential and submitted for consideration only — it isn't a guarantee, but it helps establish the circumstances these claims depend on. And where the relationship justifies it, an NDA before the detailed pitch changes the analysis entirely.

There's a broader point here worth sitting with. The concept is the part you can't lock down. The name you build on top of it — the studio, the practice, the brand people come to associate with that work — is the part you can. That's a trademark question, and it's the asset that survives everything else being copyable.

When to call ELN

If someone used your proposal, the first week matters more than the first lawyer's letter. Preserve the record, find the terms you agreed to, and get a read on whether what they took was your expression or only your idea — because those lead to different places.

ELN Law advises creators, studios, and small businesses on submission agreements, NDAs, and brand protection. Reach out through our contracts practice or schedule a consultation.
