And Linux is a trademark owned by Linus Torvalds.

man snort
       Snort has been freely available under the GPL license since 1998.

I believe the GPL says that you can't release under the GPL and then
later assert patent claims.

I doubt very much if e.g. my perl scripts to grep the output count as
derivative work, so they don't need to be GPL'd as well.

I am not a lawyer.
