Detailed information related to the European Patent.

In the Czech Republic, the validation and publication of European patents depend on the timely submission of a Czech translation, as well as compliance with local formalities, including payment of fees and appointment of legal representation.

• Translation into Czech

Czech PTO requires a Czech translation of the complete European Patent specification. The translation must be filed within three months after the publication in the European Patent Bulletin. A further three‑month grace period is available upon payment of a surcharge; if the translation is not filed within this extended period, the European patent will have no effect in the Czech Republic.

• Validation fees

The fees associated with validation of European patent in the Czech Republic are available in the fee calculator.

• Power of attorney

Legalization or notarization is not required; the Power of Attorney should be signed and dated. The original of PoA should be provided within 1-2 months from the filing of the Czech patent application. However, a scan copy is sufficient, if the original is not required by a Czech Industrial Property Office.

• Representation by a patent attorney

For foreign applicants, it is necessary to perform European patent validation in the Czech Republic through an agent registered as Czech patent attorney.
