WIPO Pearl: Improved Look and Feel

May 28, 2019

The WIPO Pearl terminology database has been redesigned and now offers a new and improved look and feel.  All of the previous functions have been maintained and the design is based on WIPO’s ePCT system for filing patent applications and so will be familiar to users of that system. In addition, the website has been adapted for use on mobile devices such as mobile phones and tablets.

We invite users who would like to send feedback on the new design to contact us.

Interface language

The WIPO Pearl interface is now available also in Arabic. This means that the interface is available now in all 10 languages featured in the WIPO Pearl database (the 10 publication languages of the PCT). Users can select their language preference at the top right of the screen.

Database contents

The WIPO Pearl database has been updated with 12,000 new patent terms, all validated by WIPO-PCT language experts. The database now contains over 172,000 terms. In addition, 17,500 concepts (or 80%) are linked to other concepts in the database, and these relationships can be browsed in our Concept Map Search. Further relationships can be shown in unvalidated “concept clouds” produced via a machine learning algorithm.

Collaboration with universities

This release also includes over 750 multilingual terminology records provided by students at the following universities, following our validation:
