Guidelines for Examination

the request is filed in writing (Rule 92(1))

the request includes the particulars of the requester required by Rule 92(2)(a), referring to Rule 41(2)(c)

the request indicates in which Contracting States the requester is the proprietor of the patent (Rule 92(2)(a))

the request indicates the number of the patent to be limited or revoked (Rule 92(2)(b))

the request indicates in which Contracting States the patent has taken effect, even if in the meantime it has lapsed in one or more of those Contracting States (Rule 92(2)(b))

in cases (iii) and (v), and if the requester is not the proprietor for all these Contracting States, the requester provides the names and addresses of the other proprietors, and evidence that he is entitled to act on their behalf (Rule 92(2)(c)); due to the retroactive effect of a limitation/revocation (Art. 68), such evidence is required also in the case where the patent has lapsed in one or more of the Contracting States referred to under (v) in the meantime. Note that in the case of joint proprietors, whether for the same or different Contracting States, the requirements of Rule 151 for appointment of a common representative also apply in the limitation or revocation procedure (see A-VIII, 1.3).

where limitation is sought, the request includes the complete version of the amended claims (and of the description and drawings where applicable) (Rule 92(2)(d))

if the requester has appointed a representative, the particulars according to Rule 41(2)(d) (Rule 92(2)(e)) have been filed.
