Can an employment NDA legally claim ownership of side projects built without company resources?

Can an employment NDA legally claim ownership of side projects built without company resources?

In most jurisdictions, an employment agreement cannot legally claim ownership of side projects created entirely on your own time, without company equipment, and unrelated to the employer's business. Overly broad clauses attempting to claim all personal work are frequently unenforceable, particularly in states with specific statutory protections.

Key takeaway: An NDA is a confidentiality agreement, not an IP assignment agreement. While they often appear together in employment contracts, they serve different legal functions. Always distinguish between your duty to keep secrets and your duty to assign inventions.

The Legal Framework: Why Overly Broad Clauses Fail

Employers often include "Invention Assignment" clauses within employment contracts. These clauses are designed to ensure the company owns the work you produce for them. However, when these clauses are drafted too broadly—claiming "all ideas, inventions, or software created during the term of employment"—they run into significant legal friction.

Statutory Protections by Jurisdiction

Several states have enacted "Employee Invention Statutes" that explicitly limit an employer's ability to claim ownership of your personal work. If you live in one of these states, your contract cannot override these protections:

• California (Labor Code § 2870): Prohibits employers from requiring employees to assign rights to inventions developed entirely on their own time without using company resources, provided the invention does not relate to the employer's business or actual/anticipated research.
• Washington (RCW 49.44.140): Similar to California, it protects inventions created on the employee's own time without employer equipment or trade secrets.
• Illinois (765 ILCS 1060/2): Provides a clear framework for when an employer can and cannot claim ownership of an invention.

Action Item: Check your state labor department website to see if your state has an "Employee Invention Act." If it does, your contract is subject to these limitations regardless of what the document says.

The Three-Prong Test for Ownership

Courts generally apply a three-prong test to determine if an employer has a valid claim to your side project. If you can answer "No" to all three, your project is likely safe:

If you used even a minor company resource, such as a company-issued laptop to write code, you have created a "nexus" that the employer can use to argue for ownership. Action Item: Always maintain a strict physical and digital separation between your work and personal projects. Use a personal machine for all side ventures.

Identifying Red Flags in Your Contract

When reviewing your employment agreement, look for these specific red flags that suggest an employer is overreaching:

• "All-Encompassing" Language: Phrases like "all inventions created during the term of employment" without any qualifying language regarding company resources or business relevance.
• Lack of Carve-outs: The absence of a "Prior Inventions" schedule or a "Personal Projects" exclusion clause.
• Broad Definition of "Business": Definitions of the company's business that are so vague they could encompass any software or creative work.

Key takeaway: If your contract lacks a specific carve-out for personal projects, you should request a "Prior Inventions" disclosure form. This allows you to list your existing side projects and explicitly exclude them from the scope of your employment agreement.

How to Protect Your Intellectual Property

If you are currently building a side project, follow these steps to minimize legal risk:

1. Document Everything: Keep a log of hours spent on your project to prove it was done outside of company time.
2. Use Personal Hardware: Never install your project's code on a company-provided machine or store it in a company-managed cloud account (like a corporate GitHub or AWS instance).
3. Disclose Early: If your project is significant, consider disclosing it to your employer and obtaining a written waiver or acknowledgment that they have no interest in the project.
4. Review the "Scope of Employment": Understand exactly what your job description entails. If your side project is completely outside that scope, your legal standing is much stronger.

Action Item: Before signing any new employment contract, ask for a "carve-out" clause that specifically excludes your personal projects from the invention assignment section. Most reasonable employers will agree to this if the project is non-competitive.
