As far as I know, there is only a patent application at this time, but
it is likely to be published as a patent eventually. The author's
company was founded in 2005. I'm not sure what "patent enforcement"
means in practice. In any case, I'm not aware of any lawsuits from
them, but I haven't looked. They have been trying to get GnuTLS to sign
their patent license though.
