Can an employer retroactively claim ownership of personal side projects via an employment NDA?

Can an employer retroactively claim ownership of personal side projects?

No, an employer cannot retroactively claim ownership of personal side projects created entirely on your own time, using your own equipment, and unrelated to the employer's business. While many employment agreements contain broad 'Invention Assignment' clauses, these are frequently limited by state law and public policy, preventing employers from overreaching into your private intellectual property.

Key takeaway: An employment contract is not a blank check for your employer to own every idea you have during your tenure. Statutory protections exist to ensure your personal innovation remains yours.

The Legal Framework of IP Ownership

In the United States, the default rule is that an employee owns their inventions unless they are created within the scope of their employment. However, employers use Proprietary Information and Inventions Agreements (PIIAs) to shift this default. These contracts often attempt to capture everything you create while employed.

The Scope of Employment Test

Courts typically evaluate three factors to determine if an employer has a valid claim to your work:

• Time: Was the project developed during working hours?
• Resources: Did you use company laptops, software licenses, or proprietary data?
• Relevance: Is the project directly related to the company’s current or anticipated business?

Action Item: Audit your current contract for the phrase 'related to the business of the Company.' If this is defined broadly, you are at higher risk.

Jurisdictional Protections

Several states have enacted specific statutes that override overly aggressive contract language. If you reside in these states, your employer's attempt to claim your side project is likely void as a matter of law.

Action Item: Check your state's labor code. If you are in a state with strong IP protections, your contract's 'assignment' clause may contain a 'savings clause' that acknowledges these statutory limits.

Red Flags in Your Employment NDA

Not all NDAs are created equal. You should be wary of specific language that attempts to bypass your rights. Watch for these common red flags:

• 'All Inventions' clauses: Language stating you assign 'all inventions conceived during the term of employment' without exception.
• 'Anticipated Business' traps: Clauses that claim ownership of anything related to the company's 'anticipated' business, which can be interpreted to cover almost any software or product.
• Lack of 'Carve-outs': The absence of a schedule or appendix where you can list pre-existing intellectual property you own before starting the job.

How to Protect Your Work

1. Document everything: Keep a log of hours spent on your project, ensuring they are outside of your 9-to-5.
2. Use your own gear: Never use your work laptop, company-provided Slack, or employer-paid software subscriptions for your side project.
3. Disclose early: If your project is in a grey area, disclose it to your manager in writing and request a written acknowledgment that it is not company property.

Key takeaway: Documentation is your best defense. If you can prove the project was developed on your own time with your own resources, you hold the leverage in any dispute.

When to Seek Legal Counsel

If your employer formally claims ownership of your side project, do not attempt to negotiate alone. The stakes involve potential loss of equity, future revenue, and intellectual property rights. Consult an employment attorney to review the specific language of your PIIA and the relevant state statutes.
