As for it being 'recognised in other EU countries', this is fallacious. It has to be granted by each and every country, and individual dues paid.
Personally I consider this one of the paradoxa of EU law. The EU regulates all sorts of useless crap across countries but these things still have to be filed in every single country, just like the certification for medical software (there finally is a central angency for pharamceuticsl products, not they dont do software).
One of the many reasons I am not all to fond of the EU.
Difficult to see how this one got through, other than the fact that it was an Italian national applying?
I agree on that one.
He will probably file more patents as an excuse to avoid independent testing.
A patent needs to describe an invention in such a way that anybody proficient in the trade can reproduce it.
So by filing a patent, he will basically enable anybody to independently reproduce and therefore verify his invention.
That does not mean that an insufficient description cant sometimes still get a patent granted, but it is rather rare.
Others have stated there is just one patent granted for EU countries
Unless this is a VERY recent change in EU patent law, you still have to file separately for every EU country, IIRC (I have my invention only protected in Austria, so I can claim prior art in case someone tries to patent it).
