PATENTSCOPE® Search Service

New possibility of carrying out multilingual searches

A new Cross-Lingual Information Retrieval (CLIR) facility is now available under the PATENTSCOPE® search service for public testing at:

http://www.wipo.int/patentscope/search/en/clir/clir.jsp

This tool allows PATENTSCOPE® users to enhance the power of their searches in the PCT and national patent collections (http://www.wipo.int/patentscope/search/en).  Using this tool, search queries in one language are translated into several other languages by special software developed by WIPO on the basis of statistical analysis of terminology in patent application texts. Performing a search based on a multilingual query can enhance the comprehensiveness of search results.  It is hoped that CLIR will open up a new way of carrying out searches of patent databases in different languages, such as the PATENTSCOPE® search service, and will significantly enhance access to patent information throughout the world.  Currently, cross-lingual search is available in the following languages:

- English

- French

- German

- Japanese

- Spanish
