Can an employment NDA legally claim ownership of projects built on my own time?

In most jurisdictions, an employment agreement cannot legally claim ownership of inventions created entirely on your own time, without using company equipment or trade secrets, and that are unrelated to the employer’s business. While employers often include broad 'Invention Assignment' clauses, state-specific labor laws frequently override these provisions to protect employee rights.

Understanding Invention Assignment Clauses

Most employment contracts contain an 'Invention Assignment' or 'Proprietary Information and Inventions Agreement' (PIIA). These clauses are designed to ensure that anything you create while employed belongs to the company. However, these clauses are not absolute. They are subject to statutory limitations that prevent employers from overreaching into your personal intellectual property.

The Three-Prong Test for Ownership

To determine if your side project is safe, courts typically look at whether the invention meets specific criteria. If your project satisfies these conditions, it is generally yours:

• No Company Resources: The invention was developed entirely on your own time without using the employer's equipment, supplies, facilities, or trade secret information.
• No Relation to Business: The invention does not relate directly to the employer's business or to the employer's actual or demonstrably anticipated research or development.
• No Connection to Duties: The invention does not result from any work performed by you for the employer.

Key takeaway: If you use your company-issued laptop to code your side project, you have likely forfeited your claim to that intellectual property, regardless of whether you worked on it after hours.

Action Item: Audit your current contract to see if the assignment clause includes a 'carve-out' section that explicitly excludes inventions developed on your own time.

Jurisdictional Differences: Why Location Matters

The enforceability of these clauses varies significantly by state. Some states have codified protections for employees, while others rely on common law.

In California, for example, Labor Code Section 2870 explicitly states that any provision in an employment agreement which provides that an employee shall assign his or her rights in an invention to his or her employer shall not apply to an invention that the employee developed entirely on his or her own time.

Action Item: Research your specific state’s 'Employee Invention' statutes. If you live in a state with strong protections, your contract’s broad language may be legally void in court.

Red Flags in Your Employment Contract

When reviewing your contract, look for these specific red flags that suggest an employer is attempting to claim ownership of your personal work:

• 'All Inventions' Language: Clauses that claim ownership of 'any and all ideas, concepts, or inventions conceived during the term of employment' without qualification.
• Broad Definition of 'Business': Definitions of the company's business that are so vague they could encompass any software or creative work.
• Lack of Exclusions: The absence of a schedule or appendix where you can list pre-existing inventions or side projects you wish to retain ownership of.

How to Negotiate Protection

If you are presented with a contract containing these red flags, you have the right to request an amendment. You can ask for an 'Excluded Inventions' schedule. This is a list attached to the contract that explicitly states: 'The following inventions were developed prior to employment or are being developed independently and are excluded from this agreement.'

Action Item: Before signing, draft a list of your current side projects and ask HR to include them in an 'Excluded Inventions' exhibit to the contract.

Best Practices for Protecting Your IP

Even with legal protections, the best defense is a clean separation between your professional and personal work.

1. Strict Hardware Separation: Never use a company laptop, tablet, or phone for personal projects.
2. Network Isolation: Do not use company VPNs, servers, or cloud storage accounts to host your personal code or files.
3. Time Management: Maintain a clear log of when you work on your personal projects to prove they were done outside of company hours.
4. IP Disclosure: If you are unsure, disclose the project to your employer in writing and request a written waiver or acknowledgment that they have no interest in the project.

Key takeaway: Documentation is your strongest evidence. Keep a digital trail showing that your project was developed independently, on personal hardware, and during non-working hours.

Action Item: Create a 'Personal IP Folder' containing your development logs, receipts for personal software/hardware purchases, and any written correspondence regarding your side projects.

Conclusion

While employers have a legitimate interest in protecting their trade secrets and core business, they cannot legally claim ownership of your personal life and independent creativity. By understanding the statutory limits of IP assignment and maintaining strict boundaries, you can protect your work.
