Can an agency legally claim ownership of pre-existing portfolio work in a Master Service Agreement?

Yes, an agency can legally retain ownership of pre-existing work, provided the Master Service Agreement (MSA) explicitly carves out 'Background IP' or 'Pre-existing Materials' from the 'Work for Hire' or 'Assignment of Rights' clauses. Without this specific carve-out, broad assignment language may inadvertently transfer ownership of your proprietary assets to the client.

Understanding the IP Ownership Framework

In the context of agency-client relationships, intellectual property is generally divided into two distinct categories. Understanding this distinction is the first step in protecting your agency's assets.

Background IP vs. Foreground IP

  • Background IP (Pre-existing Materials): Assets, tools, methodologies, code libraries, or designs created by the agency before the contract start date or developed independently of the client's project.
  • Foreground IP (Deliverables): New work created specifically for the client during the term of the agreement.

Key takeaway: If your MSA lacks a definition for 'Background IP,' a court may interpret the 'Work for Hire' clause to include everything delivered to the client, effectively stripping you of your proprietary tools.

Action Item: Audit your current MSA templates to ensure they contain a definition for 'Background IP' that explicitly excludes it from the 'Assignment of Rights' section.

Drafting Effective Carve-Out Clauses

To protect your portfolio, you must draft clauses that balance the client's need for a functional product with your need to reuse your own assets. A robust MSA should include a 'License Grant' rather than an 'Assignment' for pre-existing work.

The Hierarchy of Rights

Right TypeWho Owns It?Client Usage
Foreground IPClientFull, unrestricted ownership
Background IPAgencyLimited, non-exclusive license
Third-Party IPThird-PartySubject to external license terms

When drafting these clauses, ensure the license granted to the client is limited to the 'intended use' of the final deliverable. This prevents the client from claiming they own the underlying source code or design files that you intend to use for future clients.

Action Item: Replace blanket 'Assignment of all rights' language with a clause that states: 'Agency retains all right, title, and interest in its Background IP, and hereby grants Client a non-exclusive, perpetual, royalty-free license to use such Background IP solely as incorporated into the Deliverables.'

Common Red Flags in MSA Language

Many agencies fall into legal traps by using generic templates found online. Watch for these specific red flags that signal a risk to your portfolio ownership:

  • 'All-Encompassing' Assignment: Clauses stating that 'all work created in connection with this agreement' belongs to the client.
  • Lack of Definitions: Failing to define what constitutes a 'Deliverable' versus 'Proprietary Methodology.'
  • Indemnity Overreach: Clauses requiring the agency to indemnify the client for the use of pre-existing work that the agency actually owns.
  • Work for Hire Ambiguity: Failure to specify that only the final, paid-for deliverables are subject to the 'Work for Hire' doctrine under the U.S. Copyright Act.

Action Item: If you see the phrase 'all work product, including all underlying materials,' strike the word 'underlying' immediately. This is a common trap that captures your proprietary tools.

Jurisdictional Considerations

While the U.S. Copyright Act provides a framework for 'Work Made for Hire,' state laws regarding trade secrets and unfair competition can vary. In jurisdictions like California, courts are often protective of an agency's right to practice their trade, which includes the reuse of non-confidential methodologies. However, relying on court intervention is expensive and inefficient.

  1. Define the scope: Clearly state that the agency is an independent contractor, not an employee.
  2. Document the assets: Maintain a 'Background IP Schedule' as an exhibit to your MSA, listing the specific tools or libraries you intend to retain.
  3. Specify the license: Ensure the license is 'perpetual' so the client cannot claim the right to use the work expires if the contract ends.

Action Item: Create an 'Exhibit A' in your MSA that lists your standard proprietary frameworks or code libraries. Referencing this exhibit in your IP clause provides a clear, documented boundary for ownership.
