Can an agency legally demand ownership of pre-existing portfolio work?

Yes, an agency can legally demand ownership of your pre-existing portfolio work if you sign a Master Service Agreement (MSA) containing broad 'work-for-hire' or 'all-inclusive' intellectual property assignment clauses. While legally enforceable, these terms are often overreaching and can be successfully negotiated to protect your core assets.

The Mechanics of IP Overreach in MSAs

Agencies often use boilerplate MSAs designed to maximize their control over deliverables. When these contracts lack specific exclusions, the legal language often captures 'all materials created, conceived, or reduced to practice' during the term of the agreement. Without a carve-out, your entire portfolio history could technically fall under the client's ownership umbrella.

The 'Work-for-Hire' Trap

Under the U.S. Copyright Act, a 'work made for hire' automatically vests ownership in the hiring party. If your contract classifies your services as such, the agency may argue that any work you bring to the table—even if created years prior—is part of the 'deliverables' provided under the scope of work.

Broad IP Assignment Clauses

Many MSAs include language stating that the contractor 'hereby assigns all right, title, and interest in all intellectual property created in connection with the services.' If the definition of 'services' is broad, it creates a legal vacuum that pulls your pre-existing work into the client's ownership.

Key takeaway: Never sign an MSA that defines 'Deliverables' or 'Work Product' without explicitly excluding 'Background IP' or 'Pre-existing Materials' in a dedicated section.

Action Item: Review your current MSA for the definition of 'Work Product.' If it does not explicitly exclude pre-existing materials, you are at risk. Request an amendment immediately.

Comparison: Ownership vs. Licensing

Understanding the difference between transferring ownership and granting a license is critical for protecting your portfolio.

How to Protect Your Pre-existing Assets

To ensure you retain your portfolio, you must implement specific contractual safeguards. Do not rely on verbal assurances from agency project managers; only written contract terms hold weight in court.

  1. Define 'Background IP': Create an exhibit or schedule at the end of your MSA that lists your pre-existing tools, code, designs, and methodologies.
  2. Include a Carve-Out Clause: Insert language stating: 'Notwithstanding anything to the contrary, Contractor retains all right, title, and interest in and to all pre-existing intellectual property, including but not limited to those items listed in Exhibit A.'
  3. Grant a Limited License: Instead of assigning ownership, grant the client a 'non-exclusive, perpetual, royalty-free, worldwide license' to use the deliverables for their business purposes.
  4. Specify Portfolio Rights: Explicitly state that you retain the right to display the work in your professional portfolio and for marketing purposes, regardless of the client's ownership of the final deliverable.

Red Flags in Agency Contracts

Watch for these specific phrases that signal an attempt to claim your pre-existing work:

  • 'All work performed, whether before or after the effective date of this agreement...'
  • 'Any and all intellectual property developed by the Contractor in the field of [Industry]...'
  • 'The Client shall be deemed the sole author of all materials provided by the Contractor...'
  • 'Contractor waives all moral rights in the deliverables...'

Key takeaway: If an agency insists on owning your pre-existing work, they are effectively asking for your entire business history. This is a major red flag that suggests a lack of respect for your professional independence.

Action Item: Use a redline tool to identify these specific phrases. If you find them, strike them out and replace them with the 'Background IP' language outlined above.
