File Wrapper Mail Room Date (FW_MRDATE)

For every document that the USPTO uploads into a patent or application's file wrapper, there is an associated date.  This date is when the document was sent or received by the USPTO, or when it occured if it was, say, a set of meeting notes.  This date can be important for reasons such as to see when the patent or application was last touched, to see if something was filed timely, etc.

To search for any documents that have specific dates, use the FW_MRDATE field code.

Examples

  • FW_MRDATE:[NOW-90DAYS to NOW]  -->  Query matches all US patents or applications that have any documents in the file wrapper from the last 90 days.
  • FW_MRDATE:20170625 --> Query matches all US patents or applications that have any documents in the file wrapper that were sent or received on June 25, 2017.

Power Move:

In AcclaimIP, the FW_MRDATE field code can be used with the WITH operator.  This operator allows you to jointly query data that exist on the same line.  For example, if you wanted to find only documents that have a notice of allowance from July 15, 2016, the query would be the following:

FW_CODE:NOA WITH FW_MRDATE:20160715
