Proposals for Change (PFCs)
Proposals for change to the standard for the electronic filing and processing of international applications are published via this Web site in PFC files. Proposals, which may be submitted at any time, are processed according to the change procedure set out in proposed section 2.5 of Annex F of the PCT Administrative Instructions. Comments on current proposals may be submitted by interested persons and recommendations may be submitted by members of the Consultative Group. PFC files are updated as necessary from time to time, for example, by including any comments or recommendations received as Annexes to the files.
