Renewal work starts from one question: which registered marks expire in the coming months? Expiry dates are filters, so the API answers it directly.

​
Marks expiring in a window

Both bounds are inclusive. include_total=true returns the number of matches with the first page, so you can size the job before paging through it.

​
For a portfolio

Combine the window with an owner or representative filter. With an anchor like this, you can also sort by expiry date:
Use representative_key instead of owner_key to list the marks your firm is recorded as representing. Without an anchor filter, sort=expiry_date gets 400; sort the results yourself instead.

​
Things to check before you docket a renewal

  • The expiry date is the office’s. Pinakel never computes it. When it is null, the office did not publish one: compute the deadline from the registration date and the local term yourself, and keep it apart from office data.
  • Grace periods differ. Most offices allow late renewal with a surcharge, typically for six months after expiry, and some keep the mark as registered during that time. A registered mark with a past expiry date may be in its grace period.
  • Renewals take time to appear. After a renewal is filed, the office updates the expiry date when it records the renewal, and Pinakel picks it up at the register’s next update (see Coverage & freshness). Re-check a mark before you chase its owner.
  • dates.renewal is the date of the most recent renewal, when the office publishes it. A new renewal date with a later expiry date confirms the renewal.
  • International registrations renew at WIPO, for all designations at once. In the WO register, status.value follows the expiry date only; check national records for the state of protection in a country (see Data quality).

​
Keeping the list current

Expiry dates move when renewals are recorded. Re-run your window searches on a schedule, or keep the marks in your docket and follow their changes, as in Docketing sync. A renewal shows up as a change to dates.expiry, and often to dates.renewal and status.date.
