What is the Revision Concordance List?
Revision concordance list shows in a table how technical subject was moved between editions. Sometimes it is generated based upon the “transferred to” and “covered by” notations in IPC and it is completed with information coming from offices doing re-classification of their patent documentation. The following example is a simple and easy to understand case, which shows where the technical content related to the entries covered in edition 7 should be find in edition 6.
The Revision Concordance List shows in table form how technical subject matter was moved between subsequent editions. It indicated from which deleted groups or groups with a changed scope of the previous edition subject matter was moved to groups of the new edition. It is generated based upon the “transferred to” and “covered by” notations in the IPC and it is completed with information coming from offices doing reclassification of their patent documentation. You may view it via the internet presentation of IPC-8 (see the respective tab labelled RCL in the top-line) or download a XML version.
