This application allows you to know in advance the official fees necessary for the maintenance in force of a granted patent, depending on whether the unitary patent has been chosen or not.

Simply indicate the year the patent application was filed as well as the year the patent was issued, then specify which countries should be covered by the patent.

The application will then generate a graph allowing you to visualize the cost of annuities with the Unitary Patent in blue and without the Unitary Patent in orange. And thus compare the costs of maintaining your patent based on this choice.

A moving slider allows you to compare the cost year by year, as well as to know the total cumulative amount since issuance.

By modifying the renewal end year individually country by country and for the unitary patent, you can also obtain the same comparisons based on your abandonment forecasts for each territory.

Please note that the costs indicated do not include the fees and costs of organizations that the patentee can use to manage the renewals of its patent portfolio. In addition, the costs indicated are for payments made before the annuity due date. They do not include the surcharges which must be paid in the event of payment during the 6 months after the due date.
