Early 1990’s	The introduction of the Patents Act 1990 meant the manuals needed major revision. A plan was developed for a single comprehensive manual and the Patent Office Manual of Practice and Procedure was created in four volumes: Volume 1 – International (March 1993) Volume 2 – National (May 1994) Volume 3 – Oppositions, Courts, Extensions and Disputes (July 1993) Volume 4 – Classification, Searching and Information Technology Procedures (for internal use only) (April 1995) The approach of issuing supplementary or interim Practice Notes, C-series Circulars, and other sources of practice information ceased.

Dec 2005	Volume 5 of the Patent Manual is created – PAMS Examiner’s Reference. This consolidated all procedural information about PAMS (for internal use only).

Aug 2012	Commencement of draft changes to the manual to reflect the new provisions resulting from the Raising the Bar Bill which comes into effect on 15 April 2013. Where changes are less significant, these will be included in parts that cover both old and new practices, with their application clearly noted. Where examination practice varies pre- and post-commencement, there will be alternative parts of the manual appropriately labelled to cover both situations. To enable the timely publication of these changes, it is planned to freeze the publication of routine changes to the manual for the period January to April 2013.
