Set the filing date and initial filing country or office
In the 'Assumptions' panel (Filing strategy tab), pick the filing month/year and the office of first filing (US, FR, EP, CN, JP, PCT…). The rest of the calendar (priority year, PCT 30-month deadline, national phases) is derived from this date.

Set the applicant entity status
Standard / Small entity–SME / Micro. Applicable USPTO and other-office reductions are automatically applied where the office publishes an official reduction. Eligibility criteria for the selected office are shown just below the selector.

Pick the continuation route: PCT, EP, EP Unitary
The three checkboxes are independent. EP alone = direct EP (Paris). PCT + EP = Euro-PCT. PCT + EP Unitary = Euro-PCT then Unitary Patent. Question marks (?) beside each option explain the resulting scenario.

Add national extensions and European countries
Open 'National extensions' to add offices outside EP (US, CN, JP, KR, IN, CUSTOM via world map). Below, 'European countries selected' lists the EP validation states (FR, DE, GB, IT, ES…). Country flags help identify each jurisdiction.

Review or override the fee table
Open 'Fee settings' to inspect the locked official fees and edit the professional / agent fees per line. Add custom fee lines for anything case-specific. The 'Fees last updated' date is shown in the top strip.
