Do I own the copyright on AI-generated content? Client asking for proof

I run a content marketing agency. We use Claude and GPT-4 to draft initial content, then our writers edit and expand it. Client just asked us to warrant that we own full copyright to all deliverables and can assign it to them.

Can I actually make that warranty? I've seen conflicting info about whether AI-generated content is copyrightable at all.

Short answer: it's complicated and the law is still developing.

The Copyright Office's current position (March 2023 guidance, reaffirmed in 2024): purely AI-generated content is not copyrightable because copyright requires human authorship. BUT — content where a human provides "sufficient creative control" over the output may be copyrightable as to the human contribution.

The key question is: how much are your writers actually changing the AI output?

Honestly? It varies. Sometimes the AI output is 80% of the final piece, sometimes it's more like 30%. We always edit for accuracy, add specific examples, restructure sections.

Following this closely. I freelance and use AI for first drafts. Clients have started asking me to sign warranties that content is "not AI-generated." I've been declining those contracts but losing work.

@ContentAgency_J — here's the practical framework I use with clients:

1. If AI generates the core structure/content and humans do light editing (grammar, formatting), the copyright claim is weak.

2. If humans use AI as a research/brainstorming tool but write the actual prose themselves, copyright is strong.

3. The gray zone is where humans significantly transform AI output. There's no bright-line rule yet.

For warranty purposes, I'd suggest something like: "Agency warrants that all deliverables include substantial human authorship and creative expression, and that Agency assigns all copyright interest it holds in the deliverables to Client."

Don't forget the ToS angle. Both OpenAI and Anthropic's terms assign you ownership of outputs (subject to the same legal questions about copyrightability). But you need to comply with their usage policies — no using outputs to train competing models, disclosure requirements in some contexts, etc.

If your contract with the client transfers "all rights" but you're bound by AI provider ToS restrictions, that creates a conflict.

Why would anyone take this risk? If I'm paying for content I want to know I actually own it. The whole point of hiring writers is to get copyrightable work product.

@RiskAverse_Bob — fair point, but practically speaking, what's the actual risk? Even if the content isn't copyrightable, the client can still use it. They just can't stop competitors from copying it. For most marketing content that's... fine?

The bigger risk is the warranty itself. If you warrant full copyright ownership and it turns out you don't have it, that's breach of contract. Client could demand refund, sue for damages if they relied on that warranty.

Better to be transparent: "Content is created using AI assistance with substantial human editing and creative input. Agency assigns all copyright interest it may hold."

I've been through two rounds of this with enterprise clients. What worked: being upfront about AI use, documenting the human contribution (tracked changes showing edits), and using the "assigns all interest it holds" language. No client has pushed back once I explained the legal landscape.

The ones who demand absolute "no AI" warranties are usually more worried about quality/authenticity than copyright anyway.

UPDATE: Had the conversation with the client. Explained the current legal uncertainty, showed them our editing process (before/after comparisons). They agreed to modified language: "Agency warrants substantial human authorship and assigns all copyright interest it holds."

Also adding an AI disclosure clause to our standard MSA going forward. Thanks everyone.
