IFW Insight is a web-based application for searching, sharing and collaborating on US Patent Image File Wrapper (IFW) documents, which are also commonly referred to as “File History” documents. The IFW Insight search interface includes powerful search features including support for both proximity and Boolean search operations. The IFW Insight database currently includes over 1,000 IFW documents. IFWs are created by the USPTO as image-based documents, and are thus not searchable. Notwithstanding, by applying proprietary optical character recognition (OCR) algorithms The Patent Box is able to expose text data embedded within these image-based documents, thereby making them fully searchable.
