No, an agency cannot legally claim ownership of your pre-existing portfolio work simply by hiring you. Intellectual property rights are tied to the date of creation and the specific terms of your contract. Unless you explicitly sign away your rights in a written agreement, your prior work remains yours.

The Legal Foundation of Ownership

Under U.S. Copyright Law (and similar frameworks in the UK, Canada, and the EU), the creator of a work is the initial owner of the copyright. When you enter an agency contract, the agreement typically covers 'Work Made for Hire' or 'Assignment of Rights' for work created during the term of the contract. It does not retroactively apply to your personal portfolio or past client projects.

The Danger of 'Work Made for Hire' Clauses

Agencies often use broad 'Work Made for Hire' language. If a contract is poorly drafted, it might state that 'all work produced by the Contractor' belongs to the Agency. Without a carve-out for pre-existing work, this creates a legal ambiguity that could lead to a dispute.

Key takeaway: Always ensure your contract contains a specific 'Background IP' or 'Pre-existing Intellectual Property' clause that explicitly excludes your portfolio from the assignment of rights.

Action Item: Review your current contract for any language that claims ownership of 'all work produced' without specifying a start date or project scope.

Identifying Red Flags in Agency Contracts

When reviewing a contract, look for these specific red flags that indicate an agency is attempting to overreach into your personal intellectual property:

  • Broad Assignment Clauses: Language that says 'all intellectual property created by the Contractor, whether before or during the term of this Agreement, shall be the sole property of the Agency.'
  • Lack of Definitions: The contract fails to define 'Work Product' or 'Deliverables,' leaving the term open to interpretation.
  • Perpetual Licenses: Clauses that demand an 'irrevocable, worldwide, royalty-free license' to use your entire portfolio for any purpose.
  • Non-Compete Overlap: Using non-compete clauses to effectively block you from using your own portfolio work for other clients.
Clause TypeStandard PracticeRed Flag
Assignment of RightsLimited to project deliverablesIncludes all past and future work
Background IPExplicitly excluded/retainedNot mentioned or vaguely defined
License GrantLimited to project scopePerpetual, worldwide, and unrestricted

Action Item: If you see a 'Work Made for Hire' clause that lacks a start date, strike it out and replace it with: 'This assignment applies only to Deliverables created specifically for the Agency under this Agreement.'

How to Protect Your Portfolio

You must proactively manage your intellectual property rights before signing. Follow these steps to ensure your portfolio remains yours:

  1. Create an IP Schedule: Attach an 'Exhibit A' to your contract that lists your pre-existing work, software, or designs.
  2. Define the Scope: Clearly state that the agency is only purchasing rights to the specific deliverables created during the term.
  3. Retain a License: If you must provide the agency with access to your prior work, grant them a 'non-exclusive, limited license' to use it only for the duration of the project.
  4. Explicitly Exclude: Include a sentence stating: 'The Contractor retains all right, title, and interest in and to all pre-existing intellectual property.'

Key takeaway: Never sign a contract that does not distinguish between 'Deliverables' (what you are making for them) and 'Background IP' (what you already own).

Action Item: Create a simple document listing your core portfolio assets and reference it as 'Exhibit A' in your contract negotiations.

Jurisdictional Nuances

While the principle of ownership remains consistent in most common-law jurisdictions, the enforcement can vary. In California, for example, Labor Code Section 2870 provides specific protections for inventions created on your own time without using employer resources. However, this does not automatically protect creative designs or writing. Always consult with a local professional if you are dealing with high-value IP.
