PCT AG-IP 8.002 What are the benefits of supplementary international search for the applicant?

8.002.   What are the benefits of supplementary international search for the applicant?  Requesting supplementary international search reduces the risk of new prior art being cited in the national phase. The increasing diversity of prior art in different languages and different technical fields means that the Authority carrying out the main international search is not always capable of discovering all of the relevant prior art.  Requesting one or more supplementary international searches, during this early phase of the patent prosecution, expands both the linguistic and technical scope of the search.  In addition, it may also be possible to have the supplementary search carried out in a State where they are likely to enter the national phase later on.
