Claude/Anthropic for business use - understanding the terms and output ownership

I'm advising a client who wants to integrate Claude (Anthropic's AI) into their SaaS product. Need to understand the commercial terms better.

Specific questions:

• Consumer (claude.ai) vs API terms - what's the difference for commercial use?
• Who owns outputs when using the API commercially?
• What's their usage policy around commercial applications?
• When do you need an enterprise agreement vs standard API terms?

Anyone dealt with this?

We integrated Claude API about 6 months ago. Here's what I learned:

API vs Consumer Terms: Very different. The consumer terms (claude.ai Pro subscription) are designed for individual use. The API terms are explicitly for building products and commercial applications.

Key difference: with the API, Anthropic does NOT use your inputs/outputs to train their models by default. With the consumer product, they may (unless you opt out).

I've reviewed Anthropic's terms for several clients. Here's the breakdown:

Output Ownership (API): Similar to OpenAI, Anthropic's API terms assign output rights to you. Their terms state that as between you and Anthropic, you own the outputs, subject to their usage policies.

The same copyright caveat applies: They can assign you whatever rights they have, but if AI-generated content isn't copyrightable under current law, you're getting ownership of something with uncertain legal protection.

Usage Policies - Important for Commercial Use:

Anthropic has an Acceptable Use Policy that restricts certain applications. For your client's SaaS, review these carefully:

• No autonomous systems that could cause harm without human oversight
• Restrictions on medical/legal/financial advice without appropriate disclaimers
• No generating deceptive content (deepfakes, misinformation)
• Must comply with their safety guidelines around harmful content

Anthropic is known for their "Constitutional AI" approach - they take safety seriously and may be more restrictive than competitors in some areas.

@JessicaMoore_IP - helpful, thanks. What about enterprise agreements? My client is a Series B startup, decent size. At what point do you need a custom enterprise deal vs just using the standard API terms?

We went through this at my company (mid-market, ~500 employees). Here's when you want enterprise:

• Volume: If you're spending $10K+/month on API, enterprise pricing usually makes sense
• Security requirements: Need SOC 2 attestation, custom data handling, or specific compliance (HIPAA, etc.)
• SLAs: Standard API has no uptime guarantees. Enterprise gets SLAs.
• Custom terms: If your legal team needs to modify liability caps, indemnification, etc.

For a Series B startup just starting to integrate, standard API terms are usually fine. Negotiate enterprise when you scale.

One thing to add: Anthropic is pretty responsive to sales inquiries even for smaller companies. We weren't at enterprise volume but still got on a call with their team to clarify some terms before committing.

They also have a "Claude for Work" tier (Team/Business plans) that's between consumer and full enterprise. Might be worth looking at for your client.

Something worth flagging for commercial integrations: think about your downstream terms too.

If your client's SaaS uses Claude to generate content for THEIR customers, who owns that? Your client needs to address this in their own terms of service. The chain is:

Anthropic → Your client → Your client's customers

Make sure the client's TOS addresses AI-generated content ownership clearly. Don't just pass through Anthropic's language without thinking about it.

@LegalOps_Patricia makes an excellent point. This is where I spend a lot of time with clients.

Key drafting considerations for your client's TOS:

• Disclose that AI is being used (transparency builds trust and may be legally required in some jurisdictions soon)
• Define who owns outputs - typically the customer, but be explicit
• Include appropriate disclaimers about AI limitations
• Consider indemnification if customers misuse AI outputs
• Address what happens if Anthropic changes their policies

There's a good overview at /2024/ai-terms-of-service-saas-integration/

Don't forget data privacy angles if you're in regulated industries or dealing with EU users:

• Anthropic has a DPA (Data Processing Agreement) available for GDPR compliance
• They've published information about their data handling practices
• API data isn't used for training by default, but verify current policy
• For healthcare (HIPAA), you'll need a BAA - this usually requires enterprise tier

Constitutional AI is nice from an ethics standpoint, but make sure the compliance boxes are checked too.

This thread has been incredibly helpful. Summary of what I'm taking to my client:

Immediate steps:

• Start with standard API terms - they're commercial-friendly
• Review Acceptable Use Policy against their use case
• API outputs won't be used for training (unlike consumer product)

Legal work needed:

• Update their TOS to address AI-generated content
• Add appropriate disclaimers
• Consider their own downstream ownership provisions

Future considerations:

• Enterprise agreement when they scale past ~$10K/month or need SLAs
• DPA/BAA if they expand into regulated industries

Good summary. One final note: keep an eye on regulatory developments. The EU AI Act is coming into force gradually, and there may be disclosure requirements for AI-generated content that affect how your client needs to present their product.

Also, Anthropic (like all AI providers) reserves the right to update their terms. Build in some flexibility for your client to adapt if policies change. Maybe include a provision in their agreements about AI provider terms being subject to change.
