Congratulations, you have received the grant of a patent! The grant takes effect from the date on which it is published. Most countries issue a certificate to the proprietor in paper form. Now you have to take a lot of decisions that come along with a series of formalities: A European patent has to be validated in the member states of your choice and from that moment on renewal fees are due in all validated countries. NLO provides the full spectrum of services to help you along the way.
