International Patent Classification 2010
The International Patent Classification (IPC) version 2010.01 comes into force on 1 January 2010. From 15 December 2009, IPONZ will classify patents according to the new version.
Please note - patents applied for prior to 15 December 2009 are not automatically reclassified, may retain the retired IPC symbols, and may not include symbols introduced in the new version. When searching for a patent, IPONZ recommends that you use symbols from both the current and earlier versions of the IPC for a complete search.
