  FRS data Data provided [CZ] - Contents
1 Status Yes The following statuses are provided:

Patent revoked: Already granted document that is annulled at request of third party, EPO or IPO CZ.

Patent lapsed: Expired document – renewal fees were not paid.

Patent expired: Expired document after 20 years of patent validity.

Patent surrendered: Patent proprietor surrendered the rights to the document, i.e. patent is no longer valid.

Patent not in force: There are two reasons: Invalid document or EP ineffective from the outset.

  • Invalid document means that the document is not in force in CZ due to mistakes in proceedings (information about validity was wrong).
  • EP ineffective from the outset means that validation proceedings were not accomplished.
SPC granted: effective SPC - expired common protection of patent document with SPC period in force, i.e. de jure valid document. (please see note below)
2  Application No. Yes

IPO CZ provides its own application number format (based on the EP application number) with “CZ” in the front of it.

Czech application number format: CZYYYY-123456

CZ: notifies the user this is a czech format of EP application number
YYYY: year of filing
123456: EP Application number - zeros at the left, if any, are omitted

Example: CZ2008-829729, CZ2009-77

3 Publication No. Yes

IPO CZ does not create its own subsequent national publication numbers to identify the EP documents at the national level. Therefore, IPO CZ provides ordinary EP publication numbers.

EP Publication number format: EP1234567

EP: notifies the user this is an ordinary EP publication number
1234567: publication number completed by zeros from the left.

Example: EP1581754, EP000005, EP1876420

4  Proprietor Yes All proprietors are listed. In a link leading to IPO CZ website about particular EP all transfers of rights are reflected.
5 Invalidation date Yes "Invalidation date" means the date of invalidation coming into force or the date of execution of the request. More info in search-page tooltips or Quick help page.

According to FePR Quick Help, "The invalidation date reflects the date when the decision on the invalidation was taken". Thus, this is the date when IPO CZ made a record of it in database. Since IPO CZ’s registers are updated daily, the invalidation date and the register-last-updated date correspond. The invalidation date can be recorded quite long time after the real (official) invalidation date. It is so because a proprietor can supply the translation of granted patent at most 6 months after the date of granting – according to Czech patent law (based on European Patent Convention, Article 65).

6 Not in force since Yes Date is provided for following statuses:

Patent revoked: where the “Not in force since” date corresponds to the date of publication of the application

Patent lapsed: where the “Not in force since” date corresponds to the following day after last validity day of latest renewal fee

Patent expired: where the “Not in force since” date is the date of filing plus 20 years

Patent surrendered: where the “Not in force since” date is the date on which IPO CZ received request for withdrawal.

Patent not in force: where the “Not in force since” date corresponds to the date of filing/ priority date
 7 Renewal fees last paid Yes Renewal fees last paid: date of last payment.
Latest annual fee paid: number (in years) of annual fees already paid.

Why invalidation date often precedes Renewal-fees-last-paid date? It is a very common situation. EPO can also designate invalidation retrospectively and NPO might be informed about this event even a few months after the invalidation.

E.g. Application number EP02021072, IPO CZ was informed about invalidation on December 25th 2011 (Register-last-updated column). However, invalidation was already performed on August 2nd 2011.

 8 Register last updated Yes This date corresponds to the last update of a particular record, i.e. this is the entry date of the last item in proceedings of the record in national patent register.
 9 SPC No The IPO CZ intends to provide SPC data but it is not yet available in FRS.

Links to Supplementary Protection Certificate (SPC) requests are available within the page of the basic patent in the national phase, which is available through National patent register (the deep-link).
