Introduction

A patent may be corrected or amended in eight ways, namely by:

(1) reissue,

(2) the issuance of a certificate of correction which becomes a part of

the patent,

(3) disclaimer,

(4) reexamination,

(5) supplemental examination,

(6)

inter partes

review,

(7) post grant review, and

(8) covered business method review.

The first three ways are discussed in this chapter. The fourth way

(reexamination) is discussed in

MPEP Chapter 2200

for

ex

parte

reexamination and

MPEP Chapter 2600

for

inter

partes

reexamination requests (as of September 16, 2012 no new requests may be

filed). The fifth way (supplemental examination) is discussed in

MPEP Chapter

2800

. The sixth, seventh, and eighth ways

(inter

partes

review, post grant review, and covered business method review) are

discussed in the Office Patent Trial Practice Guide available at

www.uspto.gov/patents/ptab/resources

.

No new petitions for covered business method reviews can be

filed on or after September 16, 2020. Proceedings instituted on covered business method

review petitions filed before September 16, 2020 will continue after September 16, 2020

until the proceeding is concluded by issuance of a certificate or otherwise terminated.
