cpc_current category definition

Hi,

In the cpc_current file there is a column called category with two values: inventional and additional.  What is the definition/criteria for each of these terms?

Patents_DB_dictionary_bulk_downloads only says:

category   cpc category (primary or additional)

TIA

Andy

Re: CPC_Current Category Definition

Hi,

The category column in the cpc_current table provides information about the specific cpc code reference in a patent. Additional means that the cpc code is an additional or supplemental reference to information not directly related to the invention. Inventional means that the cpc code references information directly related to the invention.

For example, you can use the following query to view the cpc codes used in patent 9488852:
SELECT * FROM cpc_current WHERE patent_id = ‘9488852’ ORDER BY sequence;

You will see that sequence 0-7 are inventional and sequence 8 is additional.

Thanks,
