Can an agency legally claim ownership of your pre-existing freelance portfolio?

No. An agency cannot legally claim ownership of your pre-existing intellectual property unless you explicitly assign those rights in a written agreement. Standard 'work-for-hire' clauses should only apply to new deliverables created specifically for that client. If an MSA attempts to claim 'all work created by the contractor,' it is overreaching and potentially unenforceable regarding your prior portfolio.

Key takeaway: Never sign an MSA that defines 'Deliverables' or 'Work Product' broadly without an explicit carve-out for your Background IP. If you do, you risk losing the legal right to display your own portfolio work.

Understanding the 'Work-for-Hire' Trap

In the United States, the Copyright Act of 1976 dictates that 'work made for hire' belongs to the employer. However, this applies to work created during the term of the engagement. Agencies often use aggressive boilerplate language that attempts to capture 'all intellectual property created by the Contractor, whether before or during the term of this Agreement.'

Red Flags in MSA Language

  • Broad Definitions: Clauses that define work product as 'any and all creative output' without time limitations.
  • Assignment of Future Rights: Language that purports to assign rights to 'all ideas, concepts, and materials' regardless of when they were conceived.
  • Lack of Carve-outs: The absence of a specific section titled 'Background Intellectual Property' or 'Pre-existing Materials.'

Action Item: Search your MSA for the word 'all' in the IP assignment section. If it is not qualified by a date or a specific project scope, it is a red flag.

How to Protect Your Portfolio: The Background IP Clause

To maintain ownership of your portfolio, you must implement a 'Background IP' clause. This provision acts as a legal shield, explicitly stating that any work created prior to the effective date of the contract remains your sole property.

Clause TypePurposeLegal Effect
Work-for-HireAssigns new work to clientClient owns new deliverables

Steps to Secure Your IP

  1. Inventory your assets: List the specific software, code libraries, or design templates you use across multiple clients.
  2. Draft a Schedule A: Attach a document to your MSA that lists your pre-existing assets.
  3. Limit the License: If you must provide the client access to your tools, grant them a 'non-exclusive, royalty-free, perpetual license' rather than assigning ownership.

Key takeaway: A license is not an assignment. By granting a license, you keep the title to your work while allowing the client to use it for their specific project needs.

Jurisdictional Considerations

While contract law is generally consistent across the U.S., states like California (under Labor Code Section 2870) provide additional protections for employees and contractors regarding inventions created on their own time. However, relying on state law is risky; your contract is the primary document that will govern disputes. If you sign away your rights in an MSA, you may face expensive litigation to prove that the work was indeed pre-existing.

Comparing Contractual Protections

When reviewing your MSA, compare the language against these three tiers of protection:

  • Tier 1 (Weak): 'Contractor assigns all rights to all work.' (High risk of losing portfolio).
  • Tier 2 (Moderate): 'Contractor assigns rights to Deliverables created under this SOW.' (Better, but check for broad definitions).
  • Tier 3 (Strong): 'Contractor retains all rights to Background IP; Client receives a limited license to use such IP only as incorporated into the Deliverables.' (Best practice).

Action Item: If your contract is at Tier 1, request an amendment to include a 'Background IP' clause before signing.
