What is an Office of Later Examination (OLE)?

The Office of Later Examination (OLE) is the patent office with which you have filed the application whose claims correspond with those found patentable/allowable by the OEE and with which you may file the request for participation in the PPH programme. The OLE will take into account the work that has already been done by the OEE – this allows for accelerated prosecution of the application.
