What is the Image File Wrapper (IFW) system and how can I access it?
The Image File Wrapper (IFW) system is a digital system used by the USPTO to replace paper processing of patent applications. Key points about the IFW system include:
- Paper components of application files are scanned to create electronic image files.
- For applications in the IFW system, the electronic file is the Official file.
- All processing and examination is conducted using electronic images.
- IFW files are accessible through Patent Center and Private PAIR for patented applications, published applications, or applications to which a patented or published application claims domestic priority.
As stated in the MPEP: If an IFW file has been created for a patented application, published application, or an application to which a patented or published application claims domestic priority, the IFW file (with the exception of non-patent literature) is accessible through Patent Center and Private PAIR.
To access non-patent literature (NPL), you may need to contact the Patent and Trademark Copy Fulfillment Branch of the Public Records Division. For questions about IFW images viewed in Private PAIR, contact the Patent Electronic Business Center (EBC).
