Searching the EP State Data
We have included a comprehensive collection of EP state searchable fields - 24 to be precise, in which you can use to perform detailed searches. The searchable fields will search the EP states, validation status, dates of payments, as well as meta data where you can search the number of validated states, active, abandoned and so on. All of these can be combined with other searches included assignee, CPC classification, or what ever you want.
While you can search the fields directly, you can opt to use the EP Validation search form in the Search Strategies tab, which offers comprehensive searching as well - with the convenience of using a form.
Example: Here we want to find the EP patents, where Dyson is validated in both Germany and Great Britain.
The assignee is searched as it is in other forms whereas you can choose the normalized assignee in either Current, Original or Ultimate.
Further down the form we have selected DE and GB in the Record-Level Query, and selected ACTIVE in the Validation Status drop-down.
Similar to the other Search Strategy query forms, you can see the form-generated search in the results query (example below)
Notice that the EP States (using the field code EP_ST) is using the WITH operator when combined with Active (in the EP_ST_STATUS field). Using the WITH, and not AND, operator, in this case is essential when performing this search.
The WITH operator searches that particular EP State with its corresponding Status, for example FR - ABANDONED, DE - ACTIVE, GB - ACTIVE. If you used the AND in the search, then it would search all the Status regardless of if it was tied to a particular State.
So, for example, if you searched EP_ST:FR AND EP_ST_STATUS:ACTIVE, to find those active in France, it would still have retrieved this document because it wasn’t searching the Status related to FR - giving you incorrect results.
The following is the list of the searchable EP State related fields, along with descriptions and examples. They can also be found within the AcclaimIP Help Field Code Guide. Search as EP_ to retrieve a list of the EP state fields.
