How do I know whether my IP management software is ready to use the EPO’s APIs?

You should check this with your software supplier or IT department directly. 

However, if your company uses a commercially available IP management software package, you can contact us at epo.org/support or through your key account manager and we can confirm whether the software supplier has contacted us for access to test the APIs.
