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.
