Is there patent issues with daisy plasma?

Hi,

There is review request for KDE applications launcher daisy:
https://bugzilla.redhat.com/show_bug.cgi?id=577975

Homepages of project:
http://www.cdlszm.org/
http://kde-look.org/content/show.php/Daisy?content=102077

Is there patent issues similar to cairo-dock that makes impossible to have 
daisy in Fedora repository?
