A PIIA, or Proprietary Information and Invention Assignment Agreement, is a legal document in which an employee or contractor agrees to keep confidential and assign ownership rights of any intellectual property they create during their employment or engagement to their employer or client.
It is commonly used by startups and other companies to protect their intellectual property and ensure that they own the rights to any technology or products developed by their employees or contractors. The agreement typically includes provisions regarding confidentiality, ownership of intellectual property, and the disclosure of inventions or discoveries.
