Use the European Union’s official Patent Office site to search for the availability of patents within the EU and to explore international filings under the European Patent Convention. This platform offers comprehensive access to patent data across EU member states, including application details, legal status, publication history, and procedural information. It is a valuable resource for individuals and organizations looking to understand the scope of patent protection available in Europe or to track the progress of specific applications filed under the European Patent Convention.

For broader international searches, use WIPO Patentscope to examine Patent Cooperation Treaty (PCT) applications. It allows users to search for Patent Cooperation Treaty (PCT) International Patent Applications from a wide range of participating countries. Patentscope provides powerful search functionalities, including full-text searches, and covers a vast repository of international patent data. This makes it especially useful for identifying innovations protected across multiple jurisdictions, conducting prior art searches, and monitoring trends in international intellectual property activity.
