For granted EP documents, an overall status of "Active", "Expired - Lifetime", "Expired - Fee Related", "Withdrawn", "Withdrawn - After Issue", "Revoked", "Ceased", or the more generic "Not-in-force" is created, using the Inpadoc legal status events. The status is calculated in one of three ways, illustrated below. In each case, the Designated States status is reported in only two generic categories, : "In-force" or "Not-in-force":.
Case 1
When a patent has reached its full term, the status "Expired – lifetimeLifetime" will appear at the EP level. Designated States will all be listed with a status of "Not-in-force".
...
If all of the Designated States have the same status (e.g., "Expired - fee relatedFee Related", "Active", etc.), the status at the EP level will be that status common to all Designated States.
...
When a mix of only non-active statuses ("Expired - fee relatedFee Related", "Ceased", "Revoked") occurs among the Designated States, we use a generic "Not-in-force" status at the EP level as well as for the Designated States.

Case 3.3 (Special impact of the default status being activeActive)
The following example (EP-1777190-B1) illustrates the use of the default "Active" status in a record whose Designated States include a single country with no status reported. The EP in this example has expired in all jurisdictions except HK, but since there is no notice from Hong Kong through the Inpadoc legal status service, we are showing the patent as "In-force" in HK, and therefore "Active" at the EP level.
