Employee Agreement Core Clauses
  • Client Data & Code Confidentiality: Mandatory secrecy for all client repositories, APIs, and credentials.
  • Invention Assignment (PIIPA): Automatic assignment of all code, designs, and tools developed during employment.
  • Non-Solicitation of Clients: Prohibits poaching company clients for 12 to 24 months post-departure.
  • Indefinite Trade Secret Survival: Confidentiality obligations for core trade secrets survive employment termination indefinitely.

1. Why Employee Confidentiality Is Critical for Agencies

When hiring developers, engineers, and designers, agencies expose them to sensitive client repositories, trade secrets, and operational strategies. An Employee Confidentiality Agreement establishes legal guardrails.

2. Proprietary Information & Inventions Assignment (PIIPA)

A PIIPA agreement ensures that all software, inventions, algorithms, and documentation created by employees during employment automatically belong to the company.

3. Protecting Client Source Code & Third-Party Assets

Agencies are contractually liable to their clients. Ensuring employees sign strict confidentiality agreements prevents unauthorized downloading or leakage of client codebases.

4. Drafting Enforceable Non-Solicitation Clauses

Include reasonable geographical and duration caps (e.g., 12 months post-employment) to ensure non-solicitation clauses withstand judicial scrutiny in employment courts.
