Why could it be that a certain patent document is not displayed in the results list?
This is due to the fact that we only show one document per patent family, thereby eliminating duplicates and that specific document is probably one of the duplicates (equivalent). By clicking on the title of a document, you will view the bibliographic data as well as the “Also published as” section where all duplicates are listed, if available in facsimile form. Please see the patent family help file.
