USPTO Adopts PDF for Patent Documents

From Michael White’s blog – http://patentlibrarian.blogspot.ca/2013/08/uspto-adopts-pdf-for-patent-documents.html

The USPTO has adopted PDF as the default format for displaying patent documents from its databases, making it one of the last (if not last) of the major patent offices to switch to the world’s most popular document image format. Since 1998, viewing US patent documents obtained from the USPTO website required the use of a TIFF plugin such as alternaTIFF or interneTIFF.
