Welcome to the new version of the Patents Manual. Please note there are changes to the numbering and sequence of the chapters and pages in the manual. You are encouraged to take the time to explore and familiarise yourself with this new structure. International Patent Classification (IPC)

Date Published

The International Patent Classification (IPC), established by the Strasbourg Agreement 1971, provides for a hierarchical system of language independent symbols for the classification of patents and utility models according to the different areas of technology to which they pertain.

The universal use of the IPC permits the searching of multiple jurisdictions/languages (for example, both US and JP documents) in a single query. However, some national collections may not yet allow searching using English keywords or retrieving original documents, for example Italian or Indian patent collections.
