In-Depth Information
The list of the categories of documents quoted in search reports is presented in
Table 3.1 .
After receipt of the ISR, the applicant has the right to amend the claims (to
limit the scope of protection), before the publication of the application.
Further amendments to the claims, the description and the drawings are only
possible if you request an International Preliminary Examination .
After 18 months from the priority date, the application is published.
Once the first phase is over, the applicant may choose to request the interna-
tional examination and start the second phase, or leave the PCT procedure and
have the examination performed in the various countries separately.
The exam will require the filing of a Demand at the competent IPEA within
3 months from the date of forwarding of the ISR + WO or within 22 months from
the priority date. It is optional and not mandatory in the next national stages, but if
the exam is positive the European regional phase (for example) more easily results
in the grant of the European patent.
In other states a new patentability search may be carried out.
The entry into the national or regional phases is then delayed to within
30/31 months from the priority date.
The national phases consist in the validation of the international patent appli-
cation in the designated countries and the payment of national fees, the filing of
translations and the appointment of local patent agents, as required by the national
laws of each chosen country.
The period for entry into the national phase depends on the Designated or
Elected Office (if examination has been requested): for the EPO, 31 months are
