2232.01    Determining if a Reexamination Request Was Filed under 35 U.S.C. 302 for a Patent [R-07.2015]

   TO DETERMINE FROM PAIR OR PALM IF A REEXAMINATION REQUEST HAS BEEN FILED FOR A GIVEN PATENT NUMBER

Both the Internet (using PAIR) and the USPTO intranet (using PALM) can be accessed to determine if a reexamination request has been filed for a particular patent.

   Using the USPTO Intranet

- From the USPTO intranet site http://ptoweb/ptointranet/index.htm, Office personnel can click on "PALM" and then "General Information" which opens the PALM INTRANET General Information Display.

- From here, enter the patent number in the box labeled Patent #.

- Click on "Search" and when the "Patent Number Information" appears, click on "Continuity Data" to obtain the reexamination number.

Any reexamination for the patent number will be listed.

There will be about a ten (10) day lag between filing and data entry into the PALM database.
