According to the pdf Wikipedia page: "Anyone may create applications that
can read and write *PDF files* without having to pay royalties to Adobe
Systems; Adobe holds *patents* to *PDF*, but licenses them for royalty-free
use *in* developing software complying with its *PDF* specification."
ianal, but it sounds like the issues are not patent related. PDF is a
delivery form and was never designed to be editable. I think that's the

I'm currently writing an import filter to import free flow pdf text into
Scribus for editing but i'm aware that there's no free pdf editor worth
it's salt because pdf is patent encumbered. as a result all pdf editors
that let you edit free flow pdf text are quite expensive and the free
versions often limited by watermarks. anyhow, i hope i've avoided any
patent issues as layout and fonts used bare no resemblance to anything pdf
uses as I aggregate all the text and use Scribus's quite advanced layout
engine to do the bulk of the heavy lifting with some
vaguely intelligent aggregation code to aggregate the text in the filter.
can anyone give me a heads up on pdf and patents?
