¶ 14.27.06    Examples of Acceptable Terminal Disclaimer Language in Patent (Reexamination Situation)

Examples of acceptable language for making the disclaimer of the terminal portion of the patent being reexamined (or otherwise for an existing patent) follow:

  • I. If a Provisional Nonstatutory Double Patenting Rejection Over A Pending Application was made, or is otherwise believed to be applicable to the patent, use:

    The patentee, ___________, owner of __________ percent interest in the instant patent hereby disclaims the terminal part of the statutory term of the instant patent, which would extend beyond the expiration date of the full statutory term of any patent granted on pending reference application No. ______________, filed on ______________, as the term of any patent granted on said reference application may be shortened by any terminal disclaimer filed prior to the grant of any patent on the pending reference application. The patentee hereby agrees that the instant patent shall be enforceable only for and during such period that the instant patent and any patent granted on the reference application are commonly owned. This agreement is binding upon the patentee, its successors, or assigns.

  • II. If a Nonstatutory Double Patenting Rejection Over A Reference Patent was made, or is otherwise believed to be applicable to the instant patent, use:

    The patentee, ___________, owner of ________ percent interest in the instant patent hereby disclaims the terminal part of the statutory term of the instant patent, which would extend beyond the expiration date of the full statutory term of reference patent No. ______________ as the term of said reference patent is presently shortened by any terminal disclaimer. The patentee hereby agrees that the instant patent shall be enforceable only for and during such period that the instant patent and the reference patent are commonly owned. This agreement is binding upon the patentee, its successors, or assigns.

Alternatively, Form PTO/SB/25a may be used for situation I, and Form PTO/SB/26a may be used for situation II. A copy of the forms may be found at the end of MPEP § 1490.
