To search for a specific address of an inventor, use the IADR field. Inventor addresses are already parsed into City, State/Province, and Country fields with their own field codes. Therefore, the IADR field is most useful when searching for a specific street address of an inventor.

To query patents where at least one inventor is from a particular state, province of geographical sub-division, use the IS field code. Use the two letter postal code when querying the IS field. Outside of the US and Canada, this field is very sparsely populated.

If you want to view patents with no current assignee name, but those that AcclaimIP guessed, use the ANA_ANG field code.

ANA_ANG is a Boolean which means the only acceptable values are True or T, or False or F.  Booleans are not case sensitive, so ANA_ANG:T and ANA_ANG:true return the same results.

When patents and applications are published with blank assignee names, AcclaimIP can guess them with a high degree of accuracy.  We use inventor name and address fields, agent name and address fields, date fields and classification fields to guess the likely assignee of each patent.  When the confidence level is above a certain threshold, we publish the guessed assignee name in the ANG (Assignee Normalized Guessed) field, AND mark the ANA_ANG field as True.

Very often, patent applications are published with no assignee name on them, but when the patent grants, the applicant adds their name to the granted patent.  In these cases, AcclaimIP replaces the guessed assignee name on the application with the official assignee name from the granted patent.  AcclaimIP also removes the asterisk from the Current Assignee field ( * ) and flips the ANA_ANG to False.

Sometimes it is nice to understand where patents are coming from.  Assignee addresses are broken up by city, state and country.  Use the AC field code to query for assignee city.

Querying AC returns patents where the assignee address is in that city.

The AS field code queries the state or province of the assignee of a patent or application. Use the standard two-digit postal codes (ISO 3166 Codes) for the state, province or geographic subdivision.
