The Fifth Additional Provision of the LSSI (Information Society and Electronic Commerce Act) states:


One. Public administrations shall adopt the necessary measures to make information available on their respective websites accessible to persons with disabilities and the elderly in accordance with generally accepted accessibility criteria before 31 December 2005.


One of the purposes of the SPTO website is to guarantee access to the information and services on its pages without any kind of limitation or restriction due to disability or technical factors, taking into account that many of the people who view information on websites do so from different devices and contexts.


Our accessibility guidelines state the following:


  • Compliance with the WCAG guidelines (Web Content Accessibility Guidelines) of the W3C (World Wide Web Consortium) at level AA.


    W3C WAI-AA


  • Verification of compliance with the aforementioned guidelines through Web Accessibility Testing (WAT).

  • Presentation of information is based on W3C recommendations of level 2 Cascading Style Sheets (CSS2). If your browser does not support cascading style sheets, you will still be able to navigate on the website without any difficulty.


  • We have used the recommended standard for the use of XHTML code, verifying XHTML 1.0 Transitional recommendations, which means that this site can be viewed correctly in any browser that supports this standard.



Naturally, we are aware that the accessibility of this website can be improved and are working to achieve this. We invite you to help us in our efforts with your comments and suggestions.
