An international application filed via the European patent office. I would like to see an overview of the total cost in the canonical case, I mean:
- the PCT is approved
- the subsequent European patent is approved
- the maintenance fees are paid until the patent expires.
Actually such a trivial information is very difficult to find. The WIPO and the EPO websites provide a lot of information about the filing fees, but no information about the maintenance fees. Search engines point to sites set up by lawyers or agencies that spam your search, but offer no information.
I just know that the first maintenance fee kicks in three years from the filing date. Is there a place that lists all the fees? Is there any comparison with the cost of a US patent?
