Hello Everyone,

As part of our continuous effort to improve the WIPO Digital Access Service (DAS), we have recently launched a survey seeking insights from our valuable users. This initiative aims to understand better the procedures and practices of IP offices regarding the use of WIPO DAS, collect information about any fees charged for issuing and registering priority documents, and explore plans for implementing ST26 XML for national priority documents.

We would like to express our sincere gratitude to everyone who has already participated in the survey. Your input is helping us shape a more efficient and user-friendly service.

For those who haven't yet had the opportunity, we want to emphasize that your feedback is crucial. Each response we receive contributes significantly to the development and refinement of our services, and your perspective is invaluable.

The survey will close on the 15th of May, 2023. If you have not yet completed the survey, please take a moment to do so.

You can access the survey here: https://www3.wipo.int/confluence/display/dascg/1.-+Survey+on+the+operation+of+IP+offices+for+the+improvement+of+the+DAS+system.

Your responses will remain confidential and will be used exclusively to guide our efforts in improving the WIPO DAS system.

For any assistance or queries, please reach out to us at das.support@wipo.int.

Thank you for your time and for contributing to the future of WIPO DAS.
