Yes, an agency can legally demand ownership of your pre-contract portfolio work if you sign an MSA containing broad assignment language. If the contract defines 'Deliverables' or 'Work Product' to include all materials provided during the engagement without excluding pre-existing assets, you may inadvertently transfer your entire portfolio's copyright to the client.

The Legal Mechanism of IP Transfer

In the United States, the Copyright Act of 1976 governs the ownership of creative works. Under the 'Work Made for Hire' doctrine, if a contract explicitly states that work is created for hire, the hiring party is considered the legal author. Agencies often use aggressive boilerplate language to ensure they own every pixel, line of code, or word you touch during the term of the agreement.

The Danger of 'All-Encompassing' Definitions

Many MSAs define 'Work Product' as 'all materials, concepts, designs, and data provided by the Contractor to the Client.' This definition is dangerously broad. If you submit a portfolio piece as part of your pitch or onboarding, and that piece falls under the definition of 'Work Product,' the agency can argue that you have assigned all rights to that work upon signing the contract.

Key takeaway: Never sign an MSA that defines 'Work Product' without a clear, written exclusion for 'Background IP' or 'Pre-existing Materials.'

Action Item: Review your MSA's 'Definitions' section immediately. If the definition of 'Deliverables' does not explicitly exclude 'Pre-existing Intellectual Property,' you are at risk.

How to Protect Your Pre-existing Work

To maintain control over your creative history, you must negotiate specific protective language. Do not rely on verbal assurances from agency recruiters; if it is not in the contract, it is not enforceable.

1. Define 'Background IP'

Create a schedule or exhibit at the end of your contract titled 'Background IP.' List your portfolio pieces, proprietary frameworks, or code libraries here. State clearly that these items remain your sole property.

2. Use a Limited License Grant

Instead of assigning ownership, grant the client a 'non-exclusive, royalty-free, perpetual, worldwide license' to use the final deliverables. This allows the client to use the work for its intended purpose without stripping you of your underlying copyright.

3. The 'Carve-Out' Clause

Insert the following language into your IP section: 'Notwithstanding anything to the contrary, Contractor retains all right, title, and interest in and to any pre-existing materials, tools, or methodologies owned by Contractor prior to the Effective Date (collectively, "Background IP"). Client is granted no rights to Background IP except as specifically incorporated into the final Deliverables.'

Red Flags in Agency Contracts

  • 'Entire Agreement' Clauses: These clauses often invalidate any prior emails or verbal promises where you might have claimed ownership of your portfolio.
  • 'Future Works' Clauses: Some contracts attempt to claim ownership of anything you create during the term of the contract, even if it is unrelated to the project.
  • Indemnification for IP Infringement: If you assign ownership of your portfolio to an agency, you are effectively warranting that you own it. If a third party claims you infringed on their work, you could be liable for the agency's legal fees.

Action Item: If you see the phrase 'all work created during the term,' strike it out and replace it with 'all work created specifically for the Client under this Statement of Work.'
