15.4 Dynamics
The USPATFULL database follows a dynamic principle with two databases. All national publications are noted in the
PI field. The classification information in the NCLM and NCLS fields is amended when the US Classification is revised.
A document is only entered in USPAT2 when there is a second publication. An existing document in USPAT2 is
overwritten with every further (third, etc.) publication, thus only the latest document to have been published can be
found in this database. There is no document in USPAT2 if there is only one national publication.
There is a cluster USPATALL comprising the USPATFULL and USPAT2 databases.
15.5 Updating
New US patents appear in the database on the day of publication.
