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

Response submitted by Japan 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: http://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).

Please take note that some questions might not be displayed depending on the response(s) to preceding question(s). This could cause gaps in numbering of displayed questions and sections.

Section 1: Patent filing in your Office

1. Does your Office accept patent applications submitted on paper or submitted electronically but having the text body of the application submitted in image form (e.g., PDF or TIFF images)?

Yes

Please comment if necessary:

The JPO does not accept patent applications submitted electronically but having the text body of the application submitted in image form. But accepts the drawing itself including the table content and mathematical and chemical formulae as an image data.

applications filed electronically but having the text body of the application submitted in image form:

0% in 2010

3. Does your Office perform optical character recognition (OCR) on patent applications?

No

Please comment if necessary:

As the JPO consigns the OCR process to the registered data processing organizations by statute, the JPO itself does not perform OCR process.

Yes

(e) Does the storage format used by your Office retain all the raw detailed information obtained from the OCR process (e.g., individual character accuracy estimation, position in image, etc.)?

No

(f) Does the storage format used by your Office capture, in text format, table contents, and mathematical and chemical formulae?

No, it does not.

26. Is the OCR of patent documents also used to increase the efficiency of the work of the Office, (e.g., bibliographic data input from paper applications can be considerably speeded up with accurate OCR)?

We describe our customers’ usage as internal office patent application searches by examiners and Internet patent application searches by the public, etc, then, those OCRed documents are treated as the same as electronically filed documents.

29. Does your Office use OCRed patent documents provided by other offices?

Yes

Please indicate from which office(s) and for which documents, formats and purposes:

When we receive patent documents from other Offices, we do not confirm whether those are OCR processed. Whether or not OCRed, we utilize those patent documents submitted by other Offices.
