## Text

In addition to any other notices required by subparts A and C of this part, a petition must request judgment against one or more claims of a patent identified by patent number. In addition to the requirements of §§ 42.6, 42.8, 42.22, and 42.24 the petition must set forth:
(a) Grounds for standing. The petitioner must demonstrate that the patent for which review is sought is a covered business method patent, and that the petitioner meets the eligibility requirements of § 42.302.
(b) Identification of challenge. Provide a statement of the precise relief requested for each claim challenged. The statement must identify the following:
(1) The claim;
(2) The specific statutory grounds permitted under paragraph (2) or (3) of 35 U.S.C. 282(b), except as modified by section 18(a)(1)(C) of the Leahy-Smith America Invents Act (Pub. L. 112-29, 125 Stat. 284 (2011)), on which the challenge to the claim is based;
(3) How the challenged claim is to be construed. Where the claim to be construed contains a means-plus-function or step-plus-function limitation as permitted under 35 U.S.C. 112(f), the construction of the claim must identify the specific portions of the specification that describe the structure, material, or acts corresponding to each claimed function;
(4) How the construed claim is unpatentable under the statutory grounds identified in paragraph (b)(2) of this section. Where the grounds for unpatentability are based on prior art, the petition must specify where each element of the claim is found in the prior art. For all other grounds of unpatentability, the petition must identify the specific part of the claim that fails to comply with the statutory grounds raised and state how the identified subject matter fails to comply with the statute; and
(5) The exhibit number of supporting evidence relied upon to support the challenge and the relevance of the evidence to the challenge raised, including identifying specific portions of the evidence that support the challenge. The Board may exclude or give no weight to the evidence where a party has failed to state its relevance or to identify specific portions of the evidence that support the challenge.
(c) A motion may be filed that seeks to correct a clerical or typographical mistake in the petition. The grant of such a motion does not change the filing date of the petition.
