The cost of patent applications varies from country to country and depends on the route taken to pursue protection (national, European or international).
Nevertheless, there are costs other than the fee that you must pay for the application which you should consider, in particular the following:
- After the application and during the life of a patent, applicants must pay renewal fees. These payments are requested by most patent offices and are a requirement to keep patents valid (until their expiry date, which is usually after 20 years).
- The cost of services of patent attorneys or agents, which in some countries may be very high, must also be added to the total cost.
- Translation may be required, which can substantially raise the cost of a patent application.
