Locate Patents that have been Reissued?

TOPIC: Sometimes patents may be reissued. To find these reissued patents you can search any of the following databases: CLAIMS®/U.S. Patents (File 340, 341, 942), U.S. Patents Fulltext (File 652, 654, PATFULL), Derwent World Patents Index® (File 351, 352 in Japan) and INPADOC/Family and Legal Status (File 345).

In this example you will search for a patent for a type of disc brake that has been reissued. The reissued patent number is 37554.

Note: To find all reissued patents in a database:

  • In CLAIMS and U.S. Patents Fulltext, search Document Type (DT=) followed by REISSUE (e.g., S DT=REISSUE).
  • In Derwent databases search the Patent Country prefix (PC=), enter the U.S. country code, a space, then the kind code E (e.g., S PC=US E).
  • In INPADOC, enter the U.S. country code, a space, then the kind code E truncated, (e.g. S PC=US E?).
