Large decrease in number of OCID annotations

[ravwojdyla]

We have observed a large decrease in number of OCID annotations available in the recent Google Patents public data. We specifically consume the OCID associated with patents, so I will focus on that here. It appears that large number of patents that used to be annotated with OCIDs of specific entities (in our case genes), are no longer annotated by those OCIDs.

To give one specific example, if we take STAT1/ENSG00000115415 OCID:102100019657 and application US-201816499393-A, previous release had 32 OCID IDs associated with this application:

The most recent release doesn't have any, missing STAT1 annotation completely even though it's clearly in the text of the patent. Further if we count unique patents annotated with STAT1 OCID over time:

In the most recent public data there appears to be half as many publications with STAT1 annotations. Is there any specific reason for this?
