Silly software patent idea

1) produce a device with a realy nice user interface.
2) patent it as a "new" invention.
3) advertise it as "intuitive"
4) sue anyone who also thought it was "intuitive" (and obvious, but waited untill the hardware was up to it) and implements it..
5) claim in court that your "intuitive" interface didn't exist until you invented it.

Oracle buy Sun ... then

Java: let's sue
OpenOffice: forked. LibreOffice
OpenSolaris: forked
MySQL: several forks. Official support prices go up (a lot).
Hudson: forked to Jenkins, then handed to the Eclipse Foundation

Do Oracle understand the FLOSS concept ?
