WIPO Pearl

WIPO’s multilingual terminology portal gives access to scientific and technical terms derived from patent documents.  It helps promote accurate and consistent use of terms across different languages, and makes it easier to search and share scientific and technical knowledge.

Developed at WIPO by our language experts and terminologists, the database currently contains 14,951 concepts and 91,152 terms -  and is constantly growing.

Key features

  • 10 languages: Arabic, Chinese, English, French, German, Japanese, Korean, Portuguese, Russian and Spanish.
  • All the content has been validated and given a term reliability score.
  • If there is no equivalent in the target language in the database, WIPO’s machine translation engine may offer you a translation proposal.
