File via PCT (and later the Euro-PCT route) only makes sense if either:
- you want to file the application also in other countries around the world; and/or
- you want to defer filing costs for another 18 months.
In all other cases, filing directly at the EPO would be the preferred way. This will enable you a patent granting procedure which - in principle - would yield you a European patent that can be validated in more than 30 European countries. During prosecution of the European patent application, however, you only need to pay one annuity fee (i.e. the European annuity fee) in stead of several. After grant you can indeed profit from the London protocol which has minimized translation costs for a number of European countries (to view the countries that take part, see
