Our PCT Services

International Search

Search performed by an International Searching Authority (ISA) following the filing of an international patent application with a Receiving Office (RO) to find the most relevant prior art documents regarding the claimed subject matter in the application.

International Preliminary Examination

An optional part of the processing of an international patent application - often referred to as "Chapter II".

International Type Search (ITS)

An optional search carried out for national applications filed with a national patent office. The purpose of an ITS is to complement the national patent application if an applicant intends to apply for a patent in several countries.

Supplementary International Search (SIS)

Gives PCT applicants the option of requesting supplementary search from one of the participating International Search Authorities (ISA) in addition to the main PCT search, thereby reducing the likelihood of new prior art being found in the national phase.
