Patents are granted for a specific country or territory. Therefore, a patent must be requested where its interests must be safeguarded. However, in some regions, such as Europe, there are regional offices where a complete patenting process can be filed before a single authority. This is the case with the European Patent Office (EPO).
In the case of European Patents, the EPO is responsible for the processing of an application until has been granted. Once a patent has been granted, it will have the same effect as patents that have been requested through the national offices of the European Patent Convention’s (EPC) member states.
