How to Handle Employee IP Assignment

Structure IP assignment agreements to protect business assets while staying compliant with state employment laws.

  1. Draft assignment language at hiring. Include IP assignment clauses in your employment agreement or standalone invention assignment agreement. Cover inventions, discoveries, improvements, and works created during employment using company resources or relating to company business. Get signatures before the employee starts work—retroactive assignments face more legal challenges.
  2. Limit scope to work-related IP. Restrict assignments to IP created during work hours, using company equipment, or relating to company business lines. Avoid blanket assignments of all employee inventions—courts often reject overly broad claims. Include carve-outs for personal projects unrelated to your business to improve enforceability.
  3. Check state-specific restrictions. Review your state's employment laws for IP assignment limits. California, Delaware, and several others restrict employer claims to employee inventions made without company resources. Some states require specific disclosure language about employee rights. Non-compliance can void your entire assignment agreement.
  4. Document company IP development. Maintain records showing which employees worked on specific projects, when development occurred, and what company resources were used. Create invention disclosure processes requiring employees to report potentially assignable IP. Strong documentation supports your ownership claims if disputes arise.
  5. Handle departing employees systematically. Conduct exit interviews covering IP obligations and return of confidential materials. Get written confirmation that all company IP has been disclosed and assigned. Review any pending patent applications or trademark filings to ensure proper inventorship. Address ownership questions before employees leave—it's harder afterward.
  6. Monitor and enforce assignment terms. Track former employees' new ventures and patent filings that might involve your IP. Send reminder letters about assignment obligations if you spot potential violations. Budget $15,000-50,000 for IP litigation if enforcement becomes necessary—factor this cost into your IP protection strategy.
