I'll just add two extracts from Wikipedia pages:

  GNUpdf is a GNU project that aims to completely implement
  the specifications of the Portable Document Format
  standards as a free software library. On 6 October 2011,
  GNU PDF was removed from the Free Software Foundation's
  list of "high priority projects" due to the maturation of
  the Poppler library.

  There are still some technologies referenced by ISO
  32000-1 that can be incorporated into valid PDF files
  that remain proprietary (but still publicly documented),
  such as Adobe XML Forms Architecture, and JavaScript for
  Acrobat. The ISO committee is actively standardizing many
  of these as part of ISO 32000-2
