"IPC 9": entry into force on 1 January 2009

-
New versions of the core and advanced levels of the International Patent Classification (IPC) will enter into force on 1 January 2009. No further revision of the IPC will take
place before that date.

Major changes will take place in three areas – see table.

Class - Subject - Change

A01N65/00 - Biocides - New detailed subdivision in core level
H04W - Wireless - New subclass with main communication groups and a few subgroups networks in core level, most subgroups in advanced level
H04H - Broadcast - New core level scheme communication for subclass (corresponding advanced level scheme already introduced in IPC 2008.01)

The rest of the changes concern mainly maintenance, e.g. the clarification of titles, or the transfer of informative references from the scheme to the IPC definitions.
