De Clercq & Partners’ public calculator compares post-grant European patent renewal fees with or without unitary effect. Filing and grant dates and the desired countries allow national validations to be added to the comparison. Figures include official fees and the firm’s stated formality fees.
Strengths
- Focused comparison of the Unitary Patent and conventional European validations.
- Combination of unitary effect with additional countries outside its coverage.
- Annual and cumulative post-grant cost presentation.
Limitations
- The calculation covers post-grant annuities; requesting unitary effect and validation costs are excluded.
- Formality charges and currency assumptions are those used in the firm’s calculator.
