That's interesting to know - though I don't intend to read the patents

Presumably you are not suggesting that programs that manipulate PDF
files are non-free just because you can infringe a US patent by
modifying them. Are you suggesting we should avoid using PDFs?

By the way, is ReportLab (a python toolkit for generating PDFs) free
software? Their website seems not to be working at present.
