What is the significance of the Patent Law Treaty (PLT) in after final practice for reexaminations?

The Patent Law Treaty (PLT) has influenced the after final practice in reexaminations, particularly regarding extensions of time. The MPEP states:

The present after final practice of providing an automatic two-month extension for filing a response to a final Office action is in conformance with the minimum reply period provisions of the Patent Law Treaty (PLT).

As a result of this conformance with the PLT:

• An automatic two-month extension is provided for filing a response to a final Office action.
• Additional “no cause” extensions of time for filing a response to a final Office action are not available in patent owner requested or Director ordered reexaminations.
• Any extensions of time for more than two months from the time for response set in the final rejection must provide a showing of sufficient cause in accordance with 37 CFR 1.550(c)(3).

This practice ensures that the USPTO’s procedures align with international standards while maintaining the integrity of the reexamination process.
