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