Can an employment NDA legally claim ownership of freelance projects created on personal time?

Generally, no. Most jurisdictions, including California under Labor Code 2870, prohibit employers from claiming ownership of inventions or creative work developed entirely on your own time, using your own equipment, and unrelated to the employer’s actual or anticipated business. However, broad, poorly drafted contract language can create significant legal exposure.

The Legal Boundaries of IP Ownership

Employment agreements often contain "Invention Assignment" clauses. While these are standard for protecting company trade secrets, they are not absolute. Courts distinguish between work created within the scope of employment and work created as an independent pursuit.

The Three-Prong Test for Enforceability

To be legally defensible, an employer’s claim to your freelance work must typically fail all three of these criteria:

• Company Resources: Did you use company laptops, servers, proprietary software, or office space?
• Scope of Business: Does the project relate directly to the employer’s current business or their "demonstrably anticipated" research and development?
• Time and Effort: Was the work performed during your contracted working hours?

Key takeaway: If you develop a project on your own time, using your own hardware, that has nothing to do with your employer's industry, the law is heavily weighted in your favor, regardless of what the contract says.

Action Item: Audit your current employment contract for the phrase "all work created during the term of employment." If this phrase lacks qualifiers, it is a red flag that requires immediate negotiation.

Jurisdictional Variations

The enforceability of these clauses varies significantly by state. Understanding your local laws is critical for freelancers who maintain full-time employment.

In states like California, employers are legally required to provide you with written notice of your rights under Section 2870 at the time of hiring. If they fail to do so, the clause may be voided entirely.

Action Item: Search your state’s labor code for "employee invention assignment" to see if your state provides statutory protections that override restrictive contract language.

Red Flags in Your Employment Agreement

Not all IP clauses are created equal. You must identify language that attempts to overreach into your personal creative life.

• "Work Made for Hire" ambiguity: Clauses that fail to define the scope of the "work" are dangerous.
• Broad "Related to Business" definitions: If your employer defines their business as "technology" or "software," they may try to claim any code you write.
• Lack of Exclusions: A contract that does not allow for an "Excluded Inventions" schedule is a major risk.

How to Negotiate Carve-Outs

If you are currently freelancing, you should request an "Excluded Inventions" addendum. This is a list of projects you are currently working on or intend to work on that are explicitly excluded from the employer's ownership claims.

1. Draft a list of your current side projects.
2. Present this list to HR or your manager during the onboarding phase.
3. Request that this list be attached as an exhibit to your employment agreement.
4. Ensure the contract states that any future projects not using company resources are also excluded.

Key takeaway: Never sign an agreement that claims ownership of "all intellectual property created during the term of employment" without adding a written carve-out for your personal projects.

Action Item: Before signing, ask for a "Prior Inventions" disclosure form. If they don't have one, create your own and insist it be attached to the contract.

Best Practices for Maintaining Separation

Even with a strong contract, you must maintain a "clean room" environment to prevent your employer from claiming your work through circumstantial evidence.

• Hardware Separation: Never use your work laptop for personal freelance projects.
• Cloud Storage: Do not sync personal project files to company-managed cloud drives (e.g., company Google Drive or OneDrive).
• Communication: Never discuss your freelance projects on company Slack, email, or messaging platforms.
• Time Tracking: Keep a log of when you work on your personal projects to prove they occurred outside of company hours.

Action Item: Purchase a dedicated machine for your freelance work. The cost of a separate laptop is significantly lower than the cost of a legal dispute over your intellectual property.
