"United States Locking Device Patents"
The offline database currently contains approximately 36,000 patents consisting of classes 70/$, D8/330 thru D8/348. This data was loaded using automated software tools with total disregard to any errors that might occur in the USPTO database. These errors will be corrected as they are identified.
Patents issued thru 12/31/1970 (approximately) have a list of
classes which includes the current class that the patent is assigned to. This data is current
as of 1/3/2007, and will be updated periodically. Patents issued after
12/31/1970 have the SQL key word search string. This being said we do not have
the current class for these patents.

not present and in its place is the earlier mechanism patent date. This is true
