To find a reexamination record look up the patent application for the issued patent in Public PAIR.

Under the Continuity tab will be a list of child applications (if any) and reexaminations (if any).

When there is a reexamination the prosecution would be done under a new application, Please look for the prosecution history of the reexamination under the application number 90/011,079 it's has the prosecution history.

  • How did you get this application number?

  • If you describe how you got this information, then the question becomes useful for other patents too.

  • @RishiM_IPR Please add this info to the answer. The idea is to make the answer as useful as possible and not to assume a reader will look at the comments too.
