Does your current NDA cover information from a previous job?

An employment NDA typically does not cover information learned at a previous job unless you have signed a specific 'Prior Obligations' clause or if the definition of 'Confidential Information' is drafted so broadly that it encompasses all knowledge you possess, regardless of the source.

Understanding the Scope of Your NDA

Most employment agreements are designed to protect the current employer's proprietary data. However, legal drafting often creates ambiguity. You must distinguish between your general professional knowledge and specific trade secrets belonging to a former employer.

The 'Prior Obligations' Clause

Many modern employment contracts include a section titled 'Prior Obligations' or 'No Conflicts.' This clause requires you to confirm that you are not violating any previous agreements. If you sign this without disclosing your past obligations, you may be in breach of contract from day one.

Key takeaway: Never sign a 'Prior Obligations' clause without first reviewing your previous employment contracts to ensure you are not making a false representation.

Broad Definitions of Confidential Information

Check the 'Definitions' section of your NDA. If the contract defines confidential information as 'any and all information learned during the course of employment,' it is dangerously broad. You need to ensure the definition is limited to information belonging to the current employer.

Red Flags in Your Employment Contract

When reviewing your contract, look for these specific indicators that your NDA might be overreaching into your past professional life:

  • 'All Knowledge' Clauses: Language that claims ownership over any information you possess, regardless of when or where you acquired it.
  • Lack of 'Exclusion' Lists: The absence of a schedule or appendix where you can list pre-existing intellectual property or confidential information you are bound to protect.
  • Indemnification Requirements: Clauses that force you to pay the new employer's legal fees if a former employer sues you for using their trade secrets.

How to Mitigate Risk

If you are concerned about overlapping obligations, follow this step-by-step process to protect your professional standing:

  1. Audit your past contracts: Locate all previous NDAs and non-competes. Identify what information is still considered 'confidential' under those agreements.
  2. Create an Exclusion List: Draft a document listing the specific projects, trade secrets, or proprietary knowledge you are legally bound to keep confidential from your previous employer.
  3. Request a Modification: Ask your new employer to include an 'Exclusion' clause that explicitly states you are not expected to disclose or use information protected by prior agreements.
  4. Get it in writing: Ensure all disclosures regarding your prior obligations are documented in an email or an addendum to your new contract.
