WPIFV is a rolling file with records remaining in WPIFV until the value-add has been completed by Thomson Derwent analysts. The record is then added to WPIDS/WPINDEX/WPIX and the corresponding WPIFV record removed.

The majority of the records in WPIFV will be for a Basic patent. Most new Equivalent patents will continue to be added directly to WPIDS/WPINDEX/WPIX and so will not appear in WPIFV. WPIFV will however contain records for Equivalent patents to Basics which are present in WPIFV as the value add of the Basic patent has not yet been completed. In addition WPIFV will contain a small proportion of records for Equivalent patents whose Basics are already in WPIDS/WPINDEX/WPIX. This is due to the timing of the sequential production process which creates the online updates for WPIDS/WPINDEX/WPIX and WPIFV. These Equivalents will typically remain in WPIFV for one update only before they pass into WPIDS/WPINDEX/WPIX.
