Oregon Trade Name or Assumed Business Name Filing is the process of registering a business name in the state of Oregon. This allows businesses to legally operate under a name that is not their legal name. It also provides protection for the business name from being used by someone else. There are two types of Oregon Trade Name or Assumed Business Name Filing: Initial Filing and Renewal Filing. Initial Filing is the process of registering a new business name in Oregon and Renewal Filing is the process of renewing an existing business name every five years. The filing process requires submitting an application, paying applicable fees, and publishing notice of the filing in the local newspaper. Once the filing is complete, the business name is officially registered and protected from use by another business.
