What happens if a court invalidates a patent while a reissue application is pending?

If a court invalidates a patent while a reissue application is pending, several consequences may follow:

  • Notification requirement: The applicant must promptly notify the USPTO of the court’s decision.
  • Examination impact: The USPTO will consider the court’s decision in the examination of the reissue application.
  • Potential termination: The reissue application may be terminated if the entire patent is invalidated.
  • Scope adjustment: If only part of the patent is invalidated, the reissue application may need to be amended to reflect the court’s decision.

While MPEP 1442.04 does not explicitly address this scenario, it emphasizes the importance of notifying the Office of litigation developments: “Applicants should promptly notify the Office of any federal court decision involving the patent.”

The specific outcome will depend on the extent of the invalidation and the stage of the reissue examination process. Applicants should consult with legal counsel to determine the best course of action in such situations.
