The PCT International Search and Examination Guidelines

The Guidelines initially set out the framework, which is to be followed at the international search stage and the international preliminary examination stage.

The Guidelines do not have the binding authority of a legal text, but applicants may however expect the International Search Authorities (ISA) to act, as a general rule, in accordance with the Guidelines.
