Don't open the bottle of champagne too fast...

I heard it is only partial...

Let's wait and see...

"In July 2005, after several failed attempts to legalise software patents
in Europe, the patent establishment changed its strategy. Instead of
explicitly seeking to sanction the patentability of software, they are now
seeking to create a central European patent court, which would establish
and enforce patentability rules in their favor, without any possibility of
correction by competing courts or democratically elected legislators."
