Legal status data and filters

What is legal status?

Legal status tells you whether a patent is in-force or not. There are many different legal events that can cause a patent to become "dead". We collect those events and use them to determine if the patent is likely Alive or Dead. In your search results, we'll show this with a badge on each result that indicates if there are any live members in the patent's family.

Why does legal status matter?

A patent that is no longer enforceable is not a threat to your product. So when searching for freedom to operate (FTO) it is common to focus on live, granted patents.

How to filter results by legal status?

To exclude dead patents from your results, click on Patent status and change from All to Alive.

How do we calculate legal status?

We start from the assumption that the patent is alive. If there is a legal event in our database that causes the patent to no longer be in-force then we update the status to dead. That means that we'll err on the side of caution and assume patents are a live threat unless proven otherwise.

Our legal event data is only available for AU, CA, DE, EP, ES, FR, GB, JP, and US. Your results will always include include all patents from countries that we do not have legal status for. If you want to ignore those countries, you can exclude them from your results with the Patent offices filter.

Legal status is a tool to save your search and review time. For important patents you should confirm the legal status with the publishing authority and file history.
