To retain ownership of pre-existing work, you must explicitly exclude it from the Master Service Agreement (MSA) via a 'Schedule of Excluded IP.' Without a written carve-out, standard 'Work Made for Hire' clauses often inadvertently assign your entire professional portfolio to the agency.

The Anatomy of IP Assignment Clauses

Most agency MSAs are drafted to be 'all-encompassing.' They utilize broad language to ensure the agency owns everything you touch during the engagement. If you do not proactively modify these terms, you risk losing the rights to the very tools, templates, and code libraries you use to perform your work.

Common Red Flags in MSAs

  • 'All-Inclusive' Language: Clauses stating that 'all work created by the Contractor, whether before or during the term, shall be the sole property of the Agency.'
  • Lack of Definitions: Failure to distinguish between 'Deliverables' (the work for the client) and 'Background IP' (your pre-existing assets).
  • Perpetual Assignment: Language that assigns rights in perpetuity, across all media, without geographic limitation.

Key takeaway: Never sign an MSA that defines 'Work Product' without a clear, written exclusion for your pre-existing intellectual property.

How to Draft an Excluded IP Schedule

An Excluded IP Schedule is your primary defense. It acts as a legal firewall, separating your proprietary assets from the agency's deliverables. Follow these steps to draft one:

  1. Inventory your assets: List all software libraries, design templates, fonts, and methodologies you intend to use.
  2. Define the license: Grant the agency a 'non-exclusive, royalty-free, perpetual, worldwide license' to use your Background IP only as integrated into the final deliverables.
  3. Reference the schedule: Ensure the main MSA body contains a sentence: 'Notwithstanding anything to the contrary, Contractor retains all rights to the Background IP listed in Exhibit A.'

Protecting Your Right to Your Portfolio

Even if you retain ownership, you must ensure you have the right to display the work in your portfolio. Many agencies include 'Confidentiality' clauses that prevent you from disclosing the existence of the work or showing it to prospective clients. You must negotiate a 'Portfolio Exception' clause.

Essential Language for Portfolio Exceptions

  • Publicity Rights: 'Agency grants Contractor a limited, non-exclusive right to display the Deliverables in Contractor’s professional portfolio for marketing purposes.'
  • Confidentiality Carve-out: 'Confidential Information shall not include any work product that is generally known or has been publicly disclosed by the Agency.'

Key takeaway: Always request a portfolio carve-out that allows you to showcase your work after the project is completed or after a reasonable 'embargo period' of 30 to 60 days.

Strategic Negotiation Tactics

Agencies often use boilerplate contracts. When you request changes, frame them as 'industry standard' for independent contractors. If they refuse to exclude your Background IP, propose a 'License-Back' arrangement where you assign the rights but receive a perpetual, irrevocable license to use your own work for future projects.
