Full Text Search Range Broadened

Since March 26, 2007, the PatentScope database http://www.wipo.int/pctdb/en/ now allows you to search full text data from 1978 to present day - for the Latin character languages (English, French, Spanish, and German). 1978 is the first year that International Applications were published. 

Prior to March 26, 2007 it was possible to search the full text of claims and descriptions back to July 1998.

The full text data includes all published text of PCT International Applications (including bibliographic data, claims and detailed descriptions) that were filed in English, French, Spanish, or German. This 20-year extension of availability of claims and descriptions means you will get more results than searching front page bibliographic data only. For example a search of the full text for heliostat will find more results (including WO/1978/000019 for an ENERGY CONCENTRATOR SYSTEM) than a search for heliostat in the front page bibliographic data only.

To search full text in the default Structured Search interface choose "Any Field".

To search full text in the Simple Search interface you must precede your text with the field codes CL/ (to search claims) and DE/ (to search descriptions). Text not preceded by a field code will search only the front page bibliographic data in the Simple Search interface.
