Can an employer use an NDA to claim ownership of code written on personal equipment?

Can an employer claim ownership of code written on personal equipment?

An employer cannot automatically claim ownership of code written on personal equipment if the work was created entirely on your own time, without using company resources, and does not relate to the employer's current or anticipated business. However, overly broad IP assignment clauses in your employment contract may legally override these protections.

The Legal Framework of IP Assignment

Most employment contracts contain an Invention Assignment Agreement. This clause dictates that any intellectual property (IP) created during your employment belongs to the company. While these clauses are standard, they are not absolute. Their enforceability depends on the intersection of contract law and specific state statutes.

The Three-Pronged Test

In many jurisdictions, for an employer to claim ownership of your personal code, they must prove the work meets specific criteria. If you can demonstrate that your project fails any of these three prongs, the employer’s claim is likely invalid:

• Time: The work was developed entirely on your own time, outside of standard working hours.
• Resources: No company equipment, proprietary data, trade secrets, or software licenses were utilized.
• Relevance: The work does not relate directly to the employer’s business or their anticipated research and development.

Key takeaway: If you use a company-issued laptop to write a single line of code for a side project, you may have inadvertently triggered an assignment clause that grants the employer full ownership of your entire project.

Action Item: Audit your current employment agreement for the phrase "related to the business of the company." If this is defined broadly, your side projects are at higher risk.

State-Specific Statutory Protections

Several U.S. states have enacted laws that explicitly protect an employee's right to their own inventions. These statutes act as a "floor" for your rights, meaning an employer cannot contractually force you to waive these protections.

Action Item: Check if your state has an "Employee Invention Act." If you reside in a state without these protections, your contract terms are the final word on ownership.

Red Flags in Your Employment Contract

When reviewing your contract, look for these specific red flags that indicate an employer is attempting to overreach their legal rights:

• "All Inventions" Clauses: Language that claims ownership of "all inventions conceived or reduced to practice during the term of employment," regardless of whether they relate to the company.
• Broad Definition of Business: Definitions that include "any business the company may enter into in the future," which effectively captures almost any software project.
• Equipment Clauses: Language that mandates the use of company-approved hardware, which can be used to argue that you used company resources.

Action Item: If you find these clauses, request a "carve-out" or "prior inventions" disclosure form to list your existing side projects and exclude them from the agreement.

Best Practices for Protecting Your IP

To ensure your personal code remains yours, you must maintain a strict separation between your professional and personal work environments.

1. Document Everything: Keep a log of hours worked on personal projects to prove they occurred outside of company time.
2. Use Personal Hardware: Never install company software or access company repositories on your personal machine.
3. Separate Repositories: Use a personal GitHub or GitLab account that is not linked to your corporate email address.
4. Disclose Early: If you are starting a significant project, disclose it to your employer in writing to obtain a waiver or acknowledgment that it falls outside your scope of work.

Key takeaway: Documentation is your best defense. If a dispute arises, a clear paper trail showing the project was developed independently is more persuasive than a verbal agreement.

Action Item: Create a "Prior Inventions" document today. List all active side projects and store this document in a secure location to establish a baseline of ownership.

Conclusion

While employers have a legitimate interest in protecting their trade secrets, they do not have a blanket right to your personal creativity. By understanding your state's laws and the specific language in your contract, you can effectively ring-fence your personal projects from corporate claims.
