Can an employment NDA claim ownership of my pre-existing personal side projects?

No, a standard Non-Disclosure Agreement (NDA) cannot claim ownership of your pre-existing personal side projects. However, employers frequently bundle NDAs with broad Invention Assignment Agreements. If your contract lacks a specific exclusion for prior work, your employer may legally claim ownership of your side projects.

Understanding the Legal Distinction

It is critical to distinguish between an NDA and an Invention Assignment Agreement. An NDA is designed to prevent the unauthorized disclosure of trade secrets. An Invention Assignment Agreement, by contrast, is a transfer of property rights. When these are combined in a single document, the language often becomes overly broad, potentially capturing work you created years before you were hired.

The Danger of Overbroad Language

Many employment contracts contain "catch-all" clauses. These clauses often state that the employee assigns all intellectual property created "during the term of employment" or, more dangerously, "related to the company's business." If your side project is even tangentially related to your employer's industry, you are at high risk.

Key takeaway: Always check if your contract includes an 'Invention Assignment' section. An NDA alone does not grant the company ownership of your IP; the assignment clause is the mechanism that does.

Action Item: Review your employment contract for the phrase "Inventions" or "Intellectual Property Assignment." If you find it, locate the "Prior Inventions" or "Excluded Inventions" section immediately.

State-Specific Protections

Several U.S. states have enacted laws that limit an employer's ability to claim ownership of employee inventions. These statutes generally protect inventions developed entirely on your own time, without using company equipment, and that do not relate to the employer's business.

Action Item: If you reside in a state with these protections, ensure your side project documentation explicitly states that no company resources were utilized.

How to Protect Your Side Projects

To insulate your personal work from employer claims, you must establish a clear "paper trail" of ownership that predates your employment.

1. Disclose Prior Inventions: Most employment contracts include an exhibit or schedule for "Prior Inventions." List your projects there with specific dates and descriptions.
2. Segregate Resources: Never use company laptops, software licenses, or cloud storage for your side projects.
3. Maintain Separate Time: Work on your projects strictly outside of your contracted working hours.
4. Non-Competition Check: Ensure your project does not compete with your employer's current or "anticipated" business, as this is a common trigger for ownership claims.

Key takeaway: If you fail to disclose a project in the 'Prior Inventions' exhibit, you may be legally barred from claiming it as your own later.

Action Item: Create a dated document or repository for your project code or creative assets to prove existence prior to your employment start date.

Red Flags in Your Employment Contract

When reviewing your contract, look for these specific red flags that indicate your side projects might be at risk:

• "Related to Business" Clauses: Language that claims ownership of anything "related to the company's actual or anticipated business."
• "During Employment" Ambiguity: Clauses that do not explicitly exclude work done on personal time.
• Broad Definition of "Inventions": Definitions that include "ideas," "concepts," or "discoveries" rather than just "patentable inventions."
• Lack of Exclusion Schedule: The absence of an attached list where you can disclose your pre-existing work.

Action Item: If you identify these red flags, consult with an employment attorney to draft a "Side Project Disclosure" letter to be signed by your employer.
