The GPL is irrelevant here since Adobe holds the PDF
patents.
But GPL has clauses concerning patents. It demands a royalty-free
license for all. Even more, GNU Ghostscript is an official GNU-package,
and is downloadable from
gnu.org. The FSF refuses to use gif-images on
their pages because of patents. So I cannot imagine they would apply
different standards concerning pdf.
http://www.gnu.org/software/ghostscript/intro.html
Ghostscript has several main uses:
1. Display a PostScript or PDF file (avoid killing trees).
2. Convert a PostScript file to a PDF (or vice versa)
However, PDF is not an open standard because it is controlled by a
single vendor, and not some standards body. But unlike Word/doc, it is
fully documented.
