Patent Infringement Lawsuits That Involve FOSS (Groklaw)
Mijanda offers a fax to email gateway hosting service on Asterisk, a GPL licensed general purpose IP-PBX available under GNU/Linux. I believe one of the other companies involved is using Hylafax, which is another much older free software solution specific to faxing. The short list of free software packages that are potentially effected includes mgetty+sendfax, some of the fax stuff found in GNOME (and maybe KDE), hylafax, Bayonne, and Asterisk."
