§ 41.60 - Definitions.

In addition to the definitions in § 41.2, the following definitions apply to proceedings under this subpart unless otherwise clear from the context:

Appellant means any party, whether the owner or a requester, filing a notice of appeal or cross appeal under § 41.61. If more than one party appeals or cross appeals, each appealing or cross appealing party is an appellant with respect to the claims to which his or her appeal or cross appeal is directed.

Filing means filing with a certificate indicating service of the document under § 1.903 of this title.

Owner means the owner of the patent undergoing inter partes reexamination under § 1.915 of this title.

Proceeding means an inter partes reexamination proceeding. Appeal to the Board in an ex parte reexamination proceeding is controlled by subpart B of this part. An inter partes reexamination proceeding is not a contested case subject to subpart D.

Requester means each party, other than the owner, who requested that the patent undergo inter partes reexamination under § 1.915 of this title.

Respondent means any requester responding under § 41.68 to the appellant's brief of the owner, or the owner responding under § 41.68 to the appellant's brief of any requester. No requester may be a respondent to the appellant brief of any other requester.

§ 41.61 - Notice of appeal and cross appeal to Board.

(a)(1) Upon the issuance of a Right of Appeal Notice under § 1.953 of this title, the owner may appeal to the Board with respect to the final rejection of any claim of the patent by filing a notice of appeal within the time provided in the Right of Appeal Notice and paying the fee set forth in § 41.20(b)(1).

(2) Upon the issuance of a Right of Appeal Notice under § 1.953 of this title, the requester may appeal to the Board with respect to any final decision favorable to the patentability, including any final determination not to make a proposed rejection, of any original, proposed amended, or new claim of the patent by filing a notice of appeal within the time provided in the Right of Appeal Notice and paying the fee set forth in § 41.20(b)(1).

(b)(1) Within fourteen days of service of a requester's notice of appeal under paragraph (a)(2) of this section and upon payment of the fee set forth in § 41.20(b)(1), an owner who has not filed a notice of appeal may file a notice of cross appeal with respect to the final rejection of any claim of the patent.

(2) Within fourteen days of service of an owner's notice of appeal under paragraph (a)(1) of this section and upon payment of the fee set forth in § 41.20(b)(1), a requester who has not filed a notice of appeal may file a notice of cross appeal with respect to any final decision favorable to the patentability, including any final determination not to make a proposed rejection, of any original, proposed amended, or new claim of the patent.

(c) The notice of appeal or cross appeal in the proceeding must identify the appealed claim(s) and must be signed by the owner, the requester, or a duly authorized attorney or agent.

(d) An appeal or cross appeal, when taken, must be taken from all the rejections of the claims in a Right of Appeal Notice which the patent owner proposes to contest or from all the determinations favorable to patentability, including any final determination not to make a proposed rejection, in a Right of Appeal Notice which a requester proposes to contest. Questions relating to matters not affecting the merits of the invention may be required to be settled before an appeal is decided.

(e) The time periods for filing a notice of appeal or cross appeal may not be extended.

(f) If a notice of appeal or cross appeal is timely filed but does not comply with any requirement of this section, appellant will be notified of the reasons for non-compliance and given a non-extendable time period within which to file an amended notice of appeal or cross appeal. If the appellant does not then file an amended notice of appeal or cross appeal within the set time period, or files a notice which does not overcome all the reasons for non-compliance stated in the notification of the reasons for non-compliance, that appellant's appeal or cross appeal will stand dismissed.

§ 41.63 - Amendments and affidavits or other evidence after appeal.

(a) Amendments filed after the date of filing an appeal pursuant to § 41.61 canceling claims may be admitted where such cancellation does not affect the scope of any other pending claim in the proceeding.

§ 41.67 - Appellant's brief.

(a)(1) Appellant(s) may once, within time limits for filing set forth in § 41.66, file a brief and serve the brief on all other parties to the proceeding in accordance with § 1.903 of this title.

(2) The brief must be signed by the appellant, or the appellant's duly authorized attorney or agent and must be accompanied by the requisite fee set forth in § 41.20(b)(2).

(b) An appellant's appeal shall stand dismissed upon failure of that appellant to file an appellant's brief, accompanied by the requisite fee, within the time allowed under § 41.66(a).

(c)(1) The appellant's brief shall contain the following items under appropriate headings and in the order indicated in paragraphs (c)(1)(i) through (c)(1)(xi) of this section.

(i) Real party in interest. A statement identifying by name the real party in interest.

(ii) Related appeals, interferences, and trials. A statement identifying by application, patent, appeal, interference, or trial number all other prior and pending appeals, interferences, trials before the Board, or judicial proceedings known to appellant, the appellant's legal representative, or assignee which may be related to, directly affect or be directly affected by or have a bearing on the Board's decision in the pending appeal. Copies of any decisions rendered by a court or the Board in any proceeding identified under this paragraph must be included in an appendix as required by paragraph (c)(1)(xi) of this section.

(iii) Status of claims. A statement of the status of all the claims in the proceeding (e.g., rejected, allowed or confirmed, withdrawn, objected to, canceled). If the appellant is the owner, the appellant must also identify the rejected claims whose rejection is being appealed. If the appellant is a requester, the appellant must identify the claims that the examiner has made a determination favorable to patentability, which determination is being appealed.

(iv) Status of amendments. A statement of the status of any amendment filed subsequent to the close of prosecution.

(v) Summary of claimed subject matter. A concise explanation of the subject matter defined in each of the independent claims involved in the appeal, which shall refer to the specification by column and line number, and to the drawing(s), if any, by reference characters. For each independent claim involved in the appeal and for each dependent claim argued separately under the provisions of paragraph (c)(1)(vii) of this section, every means plus function and step plus function as permitted by 35 U.S.C. 112(f), must be identified and the structure, material, or acts described in the specification as corresponding to each claimed function must be set forth with reference to the specification by page and line number, and to the drawing, if any, by reference characters.

(vi) Issues to be reviewed on appeal. A concise statement of each issue presented for review. No new ground of rejection can be proposed by a third party requester appellant, unless such ground was withdrawn by the examiner during the prosecution of the proceeding, and the third party requester has not yet had an opportunity to propose it as a third party requester proposed ground of rejection.

(vii) Argument. The contentions of appellant with respect to each issue presented for review in paragraph (c)(1)(vi) of this section, and the basis therefor, with citations of the statutes, regulations, authorities, and parts of the record relied on. Any arguments or authorities not included in the brief permitted under this section or §§ 41.68 and 41.71 will be refused consideration by the Board, unless good cause is shown. Each issue must be treated under a separate heading. If the appellant is the patent owner, for each ground of rejection in the Right of Appeal Notice which appellant contests and which applies to two or more claims, the claims may be argued separately or as a group. When multiple claims subject to the same ground of rejection are argued as a group by appellant, the Board may select a single claim from the group of claims that are argued together to decide the appeal with respect to the group of claims as to the ground of rejection on the basis of the selected claim alone. Notwithstanding any other provision of this paragraph, the failure of appellant to separately argue claims which appellant has grouped together shall constitute a waiver of any argument that the Board must consider the patentability of any grouped claim separately. Any claim argued separately should be placed under a subheading identifying the claim by number. Claims argued as a group should be placed under a subheading identifying the claims by number. A statement which merely points out what a claim recites will not be considered an argument for separate patentability of the claim.

(viii) Claims appendix. An appendix containing a copy of the claims to be reviewed on appeal.

(ix) Evidence appendix. An appendix containing copies of any evidence submitted pursuant to §§ 1.130, 1.131, or 1.132 of this title or of any other evidence entered by the examiner and relied upon by appellant in the appeal, along with a statement setting forth where in the record that evidence was entered in the record by the examiner. Reference to unentered evidence is not permitted in the brief. See § 41.63 for treatment of evidence submitted after appeal. This appendix may also include copies of the evidence relied upon by the examiner in any ground of rejection to be reviewed on appeal.

(x) Related proceedings appendix. An appendix containing copies of decisions rendered by a court or the Board in any proceeding identified pursuant to paragraph (c)(1)(ii) of this section.

(xi) Certificate of service. A certification that a copy of the brief has been served in its entirety on all other parties to the reexamination proceeding. The names and addresses of the parties served must be indicated.

(2) A brief shall not include any new or non-admitted amendment, or any new or non-admitted affidavit or other evidence. See § 1.116 of this title for amendments, affidavits or other evidence filed after final action but before or on the same date of filing an appeal and § 41.63 for amendments, affidavits or other evidence after the date of filing the appeal.

(d) If a brief is filed which does not comply with all the requirements of paragraph (a) and paragraph (c) of this section, appellant will be notified of the reasons for non-compliance and given a non-extendable time period within which to file an amended brief. If appellant does not file an amended brief within the set time period, or files an amended brief which does not overcome all the reasons for non-compliance stated in the notification, that appellant's appeal will stand dismissed.

A copy of the answer shall be supplied to the owner and all requesters. If the primary examiner determines that the appeal does not comply with the provisions of §§ 41.61, 41.66, 41.67 and 41.68 or does not relate to an appealable action, the primary examiner shall make such determination of record.

(b) An examiner's answer may not include a new ground of rejection.

If the appellant does not file an amended rebuttal brief during the one-month period, or files an amended rebuttal brief which does not overcome all the reasons for non-compliance stated in the notification, that appellant's rebuttal brief and any amended rebuttal brief by that appellant will not be considered.

§ 41.73 - Oral hearing.

(a) An oral hearing should be requested only in those circumstances in which an appellant or a respondent considers such a hearing necessary or desirable for a proper presentation of the appeal. An appeal decided on the briefs without an oral hearing will receive the same consideration by the Board as an appeal decided after an oral hearing.

(b) If an appellant or a respondent desires an oral hearing, he or she must file, as a separate paper captioned “REQUEST FOR ORAL HEARING,” a written request for such hearing accompanied by the fee set forth in § 41.20(b)(3) within two months after the date of the examiner's answer. The time for requesting an oral hearing may not be extended. The request must include a certification that a copy of the request has been served in its entirety on all other parties to the proceeding. The names and addresses of the parties served must be indicated.

(c) If no request and fee for oral hearing have been timely filed by appellant or respondent as required by paragraph (b) of this section, the appeal will be assigned for consideration and decision on the briefs without an oral hearing.

(d) If appellant or respondent has complied with all the requirements of paragraph (b) of this section, a hearing date will be set, and notice given to the owner and all requesters. If an oral hearing is held, an oral argument may be presented by, or on behalf of, the primary examiner if considered desirable by either the primary examiner or the Board. The notice shall set a non-extendable period within which all requests for oral hearing shall be submitted by any other party to the appeal desiring to participate in the oral hearing. A hearing will be held as stated in the notice, and oral argument will be limited to thirty minutes for each appellant or respondent who has requested an oral hearing, and twenty minutes for the primary examiner unless otherwise ordered. No appellant or respondent will be permitted to participate in an oral hearing unless he or she has requested an oral hearing and submitted the fee set forth in § 41.20(b)(3).

(e)(1) At the oral hearing, each appellant and respondent may only rely on evidence that has been previously entered and considered by the primary examiner and present argument that has been relied upon in the briefs except as permitted by paragraph (e)(2) of this section. The primary examiner may only rely on argument and evidence relied upon in an answer except as permitted by paragraph (e)(2) of this section. The Board will determine the order of the arguments presented at the oral hearing.

(2) Upon a showing of good cause, appellant, respondent and/or the primary examiner may rely on a new argument based upon a recent relevant decision of either the Board or a Federal Court.

(f) Notwithstanding the submission of a request for oral hearing complying with this rule, if the Board decides that a hearing is not necessary, the Board will so notify the owner and all requesters.

§ 41.77 - Decisions and other actions by the Board.

(a) The Patent Trial and Appeal Board, in its decision, may affirm or reverse each decision of the examiner on all issues raised on each appealed claim, or remand the reexamination proceeding to the examiner for further consideration. The reversal of the examiner's determination not to make a rejection proposed by the third party requester constitutes a decision adverse to the patentability of the claims which are subject to that proposed rejection which will be set forth in the decision of the Patent Trial and Appeal Board as a new ground of rejection under paragraph (b) of this section. The affirmance of the rejection of a claim on any of the grounds specified constitutes a general affirmance of the decision of the examiner on that claim, except as to any ground specifically reversed.

(b) Should the Board reverse the examiner's determination not to make a rejection proposed by a requester, the Board shall set forth in the opinion in support of its decision a new ground of rejection; or should the Board have knowledge of any grounds not raised in the appeal for rejecting any pending claim, it may include in its opinion a statement to that effect with its reasons for so holding, which statement shall constitute a new ground of rejection of the claim. Any decision which includes a new ground of rejection pursuant to this paragraph shall not be considered final for judicial review. When the Board makes a new ground of rejection, the owner, within one month from the date of the decision, must exercise one of the following two options with respect to the new ground of rejection to avoid termination of the appeal proceeding as to the rejected claim:

(1) Reopen prosecution. The owner may file a response requesting reopening of prosecution before the examiner. Such a response must be either an amendment of the claims so rejected or new evidence relating to the claims so rejected, or both.

(2) Request rehearing. The owner may request that the proceeding be reheard under § 41.79 by the Board upon the same record. The request for rehearing must address any new ground of rejection and state with particularity the points believed to have been misapprehended or overlooked in entering the new ground of rejection and also state all other grounds upon which rehearing is sought.

(c) Where the owner has filed a response requesting reopening of prosecution under paragraph (b)(1) of this section, any requester, within one month of the date of service of the owner's response, may once file comments on the response. Such written comments must be limited to the issues raised by the Board's opinion reflecting its decision and the owner's response. Any requester that had not previously filed an appeal or cross appeal and is seeking under this subsection to file comments or a reply to the comments is subject to the appeal and brief fees under § 41.20(b)(1) and (2), respectively, which must accompany the comments or reply.

(d) Following any response by the owner under paragraph (b)(1) of this section and any written comments from a requester under paragraph (c) of this section, the proceeding will be remanded to the examiner. The statement of the Board shall be binding upon the examiner unless an amendment or new evidence not previously of record is made which, in the opinion of the examiner, overcomes the new ground of rejection stated in the decision. The examiner will consider any owner response under paragraph (b)(1) of this section and any written comments by a requester under paragraph (c) of this section and issue a determination that the rejection is maintained or has been overcome.

(e) Within one month of the examiner's determination pursuant to paragraph (d) of this section, the owner or any requester may once submit comments in response to the examiner's determination. Within one month of the date of service of comments in response to the examiner's determination, the owner and any requesters may file a reply to the comments. No requester reply may address the comments of any other requester reply. Any requester that had not previously filed an appeal or cross appeal and is seeking under this subsection to file comments or a reply to the comments is subject to the appeal and brief fees under § 41.20(b)(1) and (2), respectively, which must accompany the comments or reply.

(f) After submission of any comments and any reply pursuant to paragraph (e) of this section, or after time has expired, the proceeding will be returned to the Board which shall reconsider the matter and issue a new decision. The new decision is deemed to incorporate the earlier decision, except for those portions specifically withdrawn.

(g) The time period set forth in paragraph (b) of this section is subject to the extension of time provisions of § 1.956 of this title when the owner is responding under paragraph (b)(1) of this section. The time period set forth in paragraph (b) of this section may not be extended when the owner is responding under paragraph (b)(2) of this section. The time periods set forth in paragraphs (c) and (e) of this section may not be extended.

[69 FR 50003, Aug. 12, 2004, as amended at 77 FR 46631, Aug. 6, 2012]
§ 41.79 - Rehearing.

(a) Parties to the appeal may file a request for rehearing of the decision within one month of the date of:

(1) The original decision of the Board under § 41.77(a),

(2) The original § 41.77(b) decision under the provisions of § 41.77(b)(2),

(3) The expiration of the time for the owner to take action under § 41.77(b)(2), or

(4) The new decision of the Board under § 41.77(f).

(b)(1) The request for rehearing must state with particularity the points believed to have been misapprehended or overlooked in rendering the Board's opinion reflecting its decision. Arguments not raised in the briefs before the Board and evidence not previously relied upon in the briefs are not permitted in the request for rehearing except as permitted by paragraphs (b)(2) and (b)(3) of this section.

(2) Upon a showing of good cause, appellant and/or respondent may present a new argument based upon a recent relevant decision of either the Board or a Federal Court.

(3) New arguments responding to a new ground of rejection made pursuant to § 41.77(b) are permitted.

(c) Within one month of the date of service of any request for rehearing under paragraph (a) of this section, or any further request for rehearing under paragraph (d) of this section, the owner and all requesters may once file comments in opposition to the request for rehearing or the further request for rehearing. The comments in opposition must be limited to the issues raised in the request for rehearing or the further request for rehearing.

(d) If a party to an appeal files a request for rehearing under paragraph (a) of this section, or a further request for rehearing under this section, the Board shall render a decision on the request for rehearing. The decision on the request for rehearing is deemed to incorporate the earlier opinion reflecting its decision for appeal, except for those portions specifically withdrawn on rehearing and is final for the purpose of judicial review, except when noted otherwise in the decision on rehearing. If the Board opinion reflecting its decision on rehearing becomes, in effect, a new decision, and the Board so indicates, then any party to the appeal may, within one month of the new decision, file a further request for rehearing of the new decision under this subsection. Such further request for rehearing must comply with paragraph (b) of this section.

(e) The times for requesting rehearing under paragraph (a) of this section, for requesting further rehearing under paragraph (c) of this section, and for submitting comments under paragraph (b) of this section may not be extended.

§ 41.81 - Action following decision.

The parties to an appeal to the Board may not appeal to the U.S. Court of Appeals for the Federal Circuit under § 1.983 of this title until all parties' rights to request rehearing have been exhausted, at which time the decision of the Board is final and appealable by any party to the appeal to the Board.
