Missing embedding

[sanealytics]

Patent US-7398565-B1 had embedding before, but seems to have vanished recently (< 3 months). There might be others.

SELECT publication_number, embedding_v1
FROM `patents-public-data.google_patents_research.publications`
WHERE
publication_number in ('US-7398565-B1')
LIMIT 1000

Maybe they can be restored.
