Survey on the Implementation and Promotion of WIPO Standard ST.22

Response submitted by Sweden in 2011

The present questionnaire addresses issues concerning WIPO Standard ST.22 (Recommendation for the authoring of patent applications for the purpose of facilitating optical character recognition (OCR)) and patent applications submitted on paper or submitted electronically (e-filed) but having the text body of the application submitted in image form (e.g., PDF or TIFF images). Even if your Office does not perform OCR on its documents, please respond to the questions which are applicable.

A revised version of WIPO Standard ST.22 was adopted by the Standards and Documentation Working Group (SDWG) on November 21, 2008. It is available at: https://www.wipo.int/standards/en/pdf/03-22-01.pdf

The results of the survey will be presented for consideration by the Committee on WIPO Standards (CWS).
