How to determine if my employment NDA's definition of proprietary information is legally overbroad?

How to Determine if Your NDA Definition is Overbroad

An NDA definition is legally overbroad if it fails to distinguish between an employer’s specific trade secrets and your general professional knowledge. If the language captures public information, common industry practices, or your own pre-existing skills, it is likely unenforceable and poses a significant risk to your future employment.

The Anatomy of an Overbroad Definition

Employers often use 'catch-all' language to maximize control. However, courts in jurisdictions like California (under Business and Professions Code Section 16600) and New York require that proprietary information be clearly defined to protect legitimate business interests without stifling competition.

Red Flags in NDA Language

• Lack of Specificity: The definition uses vague terms like 'all information learned during employment' without narrowing it to confidential or proprietary data.
• Failure to Exclude Public Knowledge: The contract does not explicitly state that information which becomes public through no fault of your own is excluded.
• Inclusion of General Skills: The definition attempts to claim ownership over your 'methods, processes, and techniques' developed while working, which are often considered your own professional development.
• No Time Limitation: While trade secrets can be protected indefinitely, other 'confidential' information should have a reasonable expiration date (typically 2–5 years).

Key takeaway: If the definition of 'Proprietary Information' does not contain an exclusion for information that is generally known in the industry, it is almost certainly overbroad and potentially unenforceable.

Comparing Reasonable vs. Overbroad Definitions

Step-by-Step Analysis of Your NDA

1. Identify the 'Confidential Information' Clause: Locate the specific section defining what the company considers proprietary.
2. Check for Exclusions: Look for a sentence stating: 'Confidential Information does not include information that is or becomes generally known to the public through no fault of the Employee.'
3. Evaluate the 'General Knowledge' Test: Ask yourself: 'Does this definition prevent me from using the skills I learned here at a future job?' If yes, it is likely overbroad.
4. Review Jurisdiction Rules: Research your state’s stance on restrictive covenants. Some states, like California, have a very low tolerance for overbroad definitions that act as de facto non-competes.

The 'Inevitable Disclosure' Risk

An overbroad definition is often used as a weapon to trigger the 'inevitable disclosure' doctrine. This legal theory suggests that if you move to a competitor, you will inevitably use the former employer's secrets. By defining 'proprietary information' to include everything you know, the employer makes it easier to argue that your new role is a breach of contract.

Actionable Steps for Employees

If you identify an overbroad definition, you have three primary options:

• Request a Narrowing Amendment: Ask for the inclusion of a 'carve-out' clause that specifically excludes your general skills and knowledge.
• Seek Legal Counsel: If the contract is a condition of employment, consult an employment attorney to determine if the clause is void under local law.
• Document Your Baseline: Keep a record of the skills and knowledge you possessed prior to joining the company to prove that certain information was not acquired from the employer.

Key takeaway: Never assume an NDA is standard. If a clause feels like it prevents you from working in your field, it is likely an overreach that a court would strike down or narrow.
