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

In most jurisdictions, an employment NDA or IP assignment agreement cannot legally claim ownership of your personal side projects if they are developed entirely on your own time, without using company equipment, and do not relate to the employer’s actual or anticipated business or research.

The Legal Framework of IP Ownership

While employers often include "Invention Assignment" clauses in employment contracts, these are not absolute. Courts balance the employer's right to protect their trade secrets against the employee's right to pursue independent innovation. The enforceability of these clauses typically hinges on three primary factors:

• Time: Was the work performed during standard working hours or using company-paid time?
• Resources: Did you use company laptops, servers, proprietary software, or confidential data?
• Relevance: Does the project compete with the employer’s business or stem from work performed for the employer?

Key takeaway: If your project is completely unrelated to your employer's business and you have used zero company resources, the law in many states—most notably California—provides a statutory shield against employer overreach.

Action Item: Review your employment contract for an "Invention Assignment" section. If it claims ownership of "all work created during the term of employment," it is likely overbroad and potentially unenforceable in your state.

State-Specific Protections

Several states have enacted specific legislation to prevent employers from claiming ownership of employee inventions. These laws serve as a baseline for what is considered "fair" in an employment contract.

If you reside in a state without specific statutes, common law principles of "scope of employment" apply. If your project is outside the scope of your duties, the employer has a much weaker claim.

Action Item: Check your state's labor department website for "Invention Assignment" statutes. If your state has one, ensure your contract includes a disclosure statement acknowledging these rights.

Red Flags in Your NDA

Not all contracts are created equal. Some employers use "catch-all" language that is designed to intimidate employees into silence. Watch for these specific red flags:

• "All-Encompassing" Language: Clauses that claim ownership of "any and all ideas, concepts, or inventions conceived during the term of employment."
• Lack of Exclusions: The absence of a "Prior Inventions" list where you can disclose projects you started before joining the company.
• Broad Definition of Business: Definitions of the employer's business that are so vague they could encompass any software or creative project.

Action Item: If you find these red flags, request an "IP Exclusion Addendum" to explicitly list your personal projects as excluded from the assignment clause.

Best Practices for Protecting Your Work

To ensure your side projects remain yours, you must maintain a strict "firewall" between your professional duties and your personal creative work.

1. Use Personal Hardware: Never conduct side project work on a company-issued laptop or phone.
2. Avoid Company Accounts: Do not use your work email, Slack, or company-managed cloud storage (like company-wide GitHub or Google Drive) for personal projects.
3. Document Everything: Keep a log of when you work on your project to prove it was done outside of company hours.
4. Disclose Early: If you are concerned about a potential conflict, disclose the nature of your project to HR or legal in writing, emphasizing that it is unrelated to the company's business.

Key takeaway: Documentation is your best defense. If a dispute arises, proving you used personal equipment and worked outside of business hours is the most effective way to invalidate an employer's claim.

Action Item: Create a "Personal IP Folder" where you store evidence of your project's development, including timestamps and proof of personal software licenses.
