What software do I need on my computer to view and download documents in TDR?

TDR provides documents in PDF format. You will need to install a PDF viewer, such as Adobe Acrobat, to view document images in your browser. Adobe Acrobat 5, or higher, is recommended to view and print the downloaded documents; The USPTO does not endorse this product, however, these are the versions that we have been tested to date. For more information on PDF viewers please see >> Download Viewers and Plugins.
