* RDs and REs are issued in the same numeric sequence; RXs are issued in a separate numeric sequence.

** T patents were not numbered in a continuous sequence; numbers were issued in batches based on OG volume.

*** X and AI patents have non-withdrawn gaps due to patents lost in the historic Patent Office fire.

To find the most recently issued patent numbers of each patent type (i.e., the highest number issued or for which you can search each patent type), go to ftp://ftp.uspto.gov/pub/patdata/2004 and look at the most recent week's ".rpt" or ".txt" file (e.g., "04week01.rpt" for a summary of the week's issue, or "04week01.txt" for a list of all patent numbers issued in that week).
