Don’t forget that the European Patent Office (EPO) are going to raise their fees with effect from 1 April 2014.
In general, most fees will increase by around 4%. However one exception is the appeal fee which will rise by 50%, from EUR 1240 to 1860.
In addition, new filing fees for divisional applications will come into force, which will introduce larger fees for successive generations of divisional filings – EUR 210 for a second generation filing, EUR 420 for a third, EUR 630 for a fourth, and EUR 840 for the fifth and each subsequent generation.
I have prepared some tables comparing the current fees with the future new fees: EPO Fee Comparison Table
