International PCT application

The Spanish Patent and Trademark Office, in collaboration with the European Patent Office (EPO) and the World Intellectual Property Organisation (WIPO), has developed the patent e-filing service which allows users to file online applications for European, Spanish and international patents with the SPTO.

• Complete the application directly on your computer (having already checked the formal requirements).
• Attach documentation to your application (description, claims, etc.) in PDF or XML format.
• Sign and send the application in electronic format.
• Send the application to various different organisations (SPTO, WIPO, EPO, etc.).

• It saves time, thanks to the automatic confirmation of formal requirements and the address book.
• It offers a discount on application fees for national, PCT and European applications.
• Users receive instant confirmation of having filed the application. This confirmation contains the application number and the filing date.
• The highest level of security guaranteed.

To use this service, you must install a specific program which operates in conjunction with a digital ID. This program is free of charge. For further information, see the following links:
