"As I reported last week, IBM sent a list of 173 patents (67 of
them applications) to the founder of the Hercules open source
"Meanwhile I have taken a closer look at some of the patents.
The patents IBM uses against Hercules are also a potential threat
to other key FOSS projects. Based on a first analysis, those
include (but are not limited to) OpenBSD, Xen, VirtualBox, Red Hat
Enterprise Virtualization, MySQL, PostgreSQL, SQLite and Kaffe.
"I will list below the relevant patent numbers and explain why I
believe they could be used against certain projects. Considering
that IBM has already used them in a threat letter to TurboHercules,
those patents must be considered particularly dangerous. I just
explained why IBM's attack on Hercules is an attack on
interoperability and FOSS innovation in general. The fact that the
patents in action here are also a threat to other key FOSS projects
underscores the need to act."
