The European Patent Office strives to make its website accessible to people with disabilities, in accordance with the guidelines issued by the World Wide Web Consortium's Web Accessibility Initiative (WAI) .

Our goal is to achieve Level AA compliance with the Web Content Accessibility Guidelines (WCAG) 2.1.

This website has been designed to allow you to:

  • increase or decrease the size of most texts
  • navigate using keyboard shortcuts
  • use a screen reader

Accessibility checks

The EPO conducts regular automated testing on its website to identify and correct accessibility issues. Our tool checks:

  • Colour contrast
  • Alternative texts for images
  • Headings
  • Form labels
  • Keyboard accessibility
  • Accessible rich internet application (ARIA) attributes
  • Landmarks
  • Tables

The tool is set up to test for WCAG 2.1 Level A and AA and WAI-ARIA 1.2.

While we strive to achieve Level AA compliance, some content and services may not be accessible, including:

  • some of the EPO’s online services and advanced tools linked from this website
  • PDFs and other downloads linked from this website
  • some images which may not have a text alternative, or where the text may not describe the image accurately
