Can an employer enforce an NDA to restrict open-source contributions made on personal time?

In most jurisdictions, an employer cannot legally claim ownership of open-source contributions made entirely on personal time, using personal equipment, and unrelated to the employer's business. However, overly broad IP assignment clauses in employment contracts can create significant legal risk, potentially allowing employers to assert ownership or restrict your activity.

The Legal Landscape of IP Assignment

Employment contracts often contain "Invention Assignment" clauses. These clauses are designed to ensure the company owns the intellectual property (IP) you create while employed. The enforceability of these clauses regarding side projects depends heavily on state law and the specific language of your contract.

State-Specific Protections

Several states have enacted "Employee Invention Statutes" that explicitly protect your right to work on projects outside of your employment. For example, California Labor Code Section 2870 provides a statutory shield for employees.

• California (Section 2870): Protects inventions developed on your own time, without company equipment, and that do not relate to the employer's business or actual/anticipated research.
• Washington (RCW 49.44.140): Similar protections for employees, provided the invention does not result from work performed for the employer.
• Illinois (Employee Patent Act): Limits the scope of assignment agreements to inventions that relate directly to the employer's business.

Key takeaway: Even if your contract says the employer owns "everything you create," state law may override that language if your project is unrelated to your job duties.

Red Flags in Your Employment Agreement

When reviewing your contract, look for specific language that signals an overreach. If you find these terms, you should seek clarification or a written waiver.

Identifying Overly Broad Language

• "Any and all inventions": This phrasing is often too broad and may be unenforceable in states like California.
• "Related to the business": This is the most contested phrase. If your employer is a cloud provider, contributing to a cloud-related open-source project could be flagged as "related."
• "During the term of employment": This implies 24/7 ownership, which is rarely enforceable for personal projects.

Best Practices for Protecting Your Side Projects

To ensure your open-source contributions remain yours, you must maintain a strict "firewall" between your professional life and your personal coding.

1. Use Personal Hardware: Never use a company-issued laptop, tablet, or phone for personal projects.
2. Avoid Company Software: Do not use company-licensed IDEs, compilers, or cloud accounts (like AWS or Azure) for your personal code.
3. Document Everything: Keep a log of your development hours. If you are challenged, proving you worked on the project on weekends or evenings is critical.
4. Request a Carve-Out: If you have a significant side project, ask your employer to sign an "IP Exclusion Agreement" or a "Prior Inventions Disclosure" form.

Key takeaway: If you use company resources, you have likely forfeited your claim to the IP. Always maintain a clean separation of assets.

When to Seek Legal Counsel

If your employer explicitly demands you stop contributing to an open-source project, or if they claim ownership of a project you have already published, you are in a high-risk scenario. You should consult with an employment attorney who specializes in technology law to determine if your specific contract language is preempted by state law.
