I found one European patent about 10 years old. How can I check if patent realy valid? Did owners made all payment needed, and so on?

Hi. Go to Espacenet and search for the patent that you are interested in.
http://ep.espacenet.com/?locale=en_EP

such as this
http://ep.espacenet.com/publicationDetails/biblio?KC=A1&date=20081126&NR=1995414A1&DB=ep.espacenet.com&locale=en_EP&CC=EP&FT=D

Then on the bibliographic data page, click on "View document in the European register"

(hope the links work)

At the bottom you can see Fees paid, countries lapsed, etc.
