Request for Extension of Time to File Brief
Note:
Patent owners can request additional time to file a brief by paying an extension fee and submitting the request to the Central Reexamination Unit or Technology Center before the original deadline.

In the event that the patent owner finds themself unable to file a brief within the time allowed by the rules, they may file a request with the appropriate extension of time fee, to the Central Reexamination Unit (CRU) or Technology Center (TC), requesting additional time. See MPEP § 2265 for specific guidance. The request should contain the address to which the response is to be sent. If the request and the required fee are filed prior to the expiration of the period sought to be extended (37 CFR 1.550(c)), the CRU SPRS or TC Director is authorized to grant the extension for up to one month in third party requested reexamination proceedings, and for up to two months (i.e., a “no cause” extension) in patent owner requested reexamination proceedings (including reexaminations ordered under 35 U.S.C. 257) or Director ordered reexamination proceedings. Requests for extensions of time for more than one month in third party requested reexaminations and for more than two months in patent owner requested reexaminations (including reexaminations ordered under 35 U.S.C. 257) or Director ordered reexaminations, will also be decided by the CRU SPRS or TC Director, but will not be granted unless extraordinary circumstances are involved; e.g., death or incapacitation of the patent owner. The time extended is added to the last calendar day of the original period, as opposed to being added to the day it would have been due when said last day is a Saturday, Sunday, or federal holiday.

Board Determines Appeal Brief Compliance Before Forwarding
Note:
The Patent Trial and Appeal Board is responsible for ensuring appeal briefs in ex parte reexamination proceedings comply with 37 CFR 41.37 before forwarding them to the examiner.

Since May 25, 2010, the Patent Trial and Appeal Board, (Board), has the sole responsibility for determining whether appeal briefs filed in ex parte reexamination proceedings comply with 37 CFR 41.37, and will complete the determination before the appeal brief is forwarded to the examiner for consideration. If the appeal brief is determined to be compliant with the rules or it contains only minor informalities that do not affect the Board panel’s ability to render a decision, the Board will accept the appeal brief and forward it to the examiner for consideration. If the Board determines that the appeal brief is non-compliant with 37 CFR 41.37 and sends appellant a notice of non-compliant brief requiring a corrected brief, appellant will be required to file a corrected brief within the time period set forth in the notice to avoid the dismissal of the appeal. The Board also has the sole responsibility for determining whether corrected briefs comply with 37 CFR 41.37, and addresses any inquiries and petitions regarding notices of non-compliant briefs.

Compliant Appeal Brief Not Held Defective
Note:
An appeal brief that meets the requirements of 37 CFR 41.37 will not be deemed defective by the CRU or examiner.

Once an appeal brief is accepted by the Board as in compliance with 37 CFR 41.37, the appeal brief will not later be held as defective by the CRU or the examiner. The Board will not return or remand the proceeding to the examiner for issues related to a non-compliant appeal brief. Furthermore, examiners are not required to review appeal briefs for the purposes of determining whether the appeal briefs comply with 37 CFR 41.37. Accordingly, the Notification of Non-Compliant Appeal Brief (PTOL-462R) and form paragraphs for holding an appeal brief defective are no longer be available for the CRU to use.

Serious Defects Require Examiner Report to CRU Director
Note:
When an appeal brief contains serious defects preventing the examiner from drafting an answer, the examiner must report the issue to the CRU Director who will communicate with the Board if necessary.

Examiners are no longer to hold any appeal briefs defective. Rather, the Board will correspond directly with the appellant on non-compliant brief issues. In a rare situation where an appeal brief contains serious defects that will prevent the examiner from drafting an examiner’s answer, the examiner should report the issue to the Director of CRU who will communicate with the Board regarding the issue if appropriate.

Requirement for Proper Brief Filing
Note:
The rule requires that a brief must set forth authorities and arguments, failing which grounds of rejection may be summarily sustained.

It is to be noted that the mere filing of any paper whatsoever entitled as a brief cannot necessarily be considered as compliance with 37 CFR 41.37. The rule requires that the brief must set forth the authorities and arguments relied on, and to the extent that it fails to do so with respect to any ground of rejection, that ground may be summarily sustained. A distinction must be made between the lack of any argument and the presentation of arguments that carry no conviction. In the former case summarily sustaining the rejection is in order, while in the latter case a decision on the merits is made, although it may well be merely an affirmance based on the grounds relied on by the examiner.

Review SNQ Issue Along With Rejections on Appeal
Note:
Patent owner must include SNQ issue and arguments in appeal brief to the Board for review, after first requesting reconsideration from the examiner.

The patent owner may seek review on the examiner's SNQ determination before the Board along with any appeal of the examiner's rejections. To obtain review of the SNQ issue, patent owner must include the SNQ issue and the appropriate arguments in its appeal brief to the Board. In order to preserve the right to have the Board review of the SNQ issue, a patent owner must have first requested reconsideration of the SNQ issue by the examiner. Accordingly, for ex parte reexamination proceedings ordered on or after June 25, 2010, the patent owner may seek a final agency decision from the Board on the SNQ issue only if the patent owner has first requested reconsideration before the examiner (e.g., in a patent owner's statement under 37 CFR 1.530 or in a patent owner's response under 37 CFR 1.111) and then seeks review of the examiner's SNQ determination before the Board. In its appeal brief, the patent owner is to clearly present the issue and arguments regarding the examiner's SNQ determination under a separate heading and identify the communication in which the patent owner first requested reconsideration before the examiner. (For ex parte reexamination proceedings ordered prior to June 25, 2010, if the patent owner presents the SNQ issue in its appeal brief, the Board panel will review the procedural SNQ issue along with its review of any rejections in an appeal and will enter a final agency decision accordingly.)

Requirement for Corrected Appeal Brief Within Time Period
Note:
Appellant must file a corrected brief within the time period set by the Board to avoid dismissal of the appeal if the initial brief is found non-compliant with 37 CFR 41.37.

Since May 25, 2010, the Patent Trial and Appeal Board, (Board), has the sole responsibility for determining whether appeal briefs filed in ex parte reexamination proceedings comply with 37 CFR 41.37, and will complete the determination before the appeal brief is forwarded to the examiner for consideration. If the appeal brief is determined to be compliant with the rules or it contains only minor informalities that do not affect the Board panel’s ability to render a decision, the Board will accept the appeal brief and forward it to the examiner for consideration. If the Board determines that the appeal brief is non-compliant with 37 CFR 41.37 and sends appellant a notice of non-compliant brief requiring a corrected brief, appellant will be required to file a corrected brief within the time period set forth in the notice to avoid the dismissal of the appeal. The Board also has the sole responsibility for determining whether corrected briefs comply with 37 CFR 41.37, and addresses any inquiries and petitions regarding notices of non-compliant briefs.

Therefore, the examiner will treat all pending, rejected claims as being on appeal, and the examiner must maintain all of the rejections set forth in the Office action from which the appeal is taken, unless appellant has overcome the rejection (e.g., by submitting persuasive arguments, an acceptable terminal disclaimer, or evidence). In situations where the appellant makes a request to hold a rejection in abeyance or did not present any argument on a rejection in the appeal brief, the examiner should maintain the rejection in the examiner’s answer.

Claims Must Include Underlining and Bracketing
Note:
Patent claims on appeal in reexamination must include all underlining and bracketing to reflect changes made during prosecution.

For the sake of convenience, the copy of the claims involved should be double spaced and should start on a new page. Note that the copy of the claims on appeal in reexamination proceedings must include all underlining and bracketing, as required by 37 CFR 1.530(f), to reflect the changes made to the original patent claims throughout the prosecution of the reexamination. In addition, any new claims added in the reexamination should be completely underlined. This represents a departure from the procedure set forth in MPEP § 1205.02 for applications.

Final Board Decision Directly Appealable to Federal Circuit
Note:
The patent owner can appeal the Board's final decision, which includes a SNQ finding, directly to the U.S. Court of Appeals for the Federal Circuit.

The patent owner may file a single request for rehearing under 37 CFR 11.52 for both the decision on the SNQ issue and the merits decision on the examiner's rejections, resulting in a single final decision for purposes of judicial review. Judicial review of the Board's final decision issued pursuant to 35 U.S.C. 134, which will incorporate the decision on the finding of a SNQ, is directly appealable to the United States Court of Appeals for the Federal Circuit under 35 U.S.C. 141. See In re Hiniker Co., 150 F.3d 1362, 1367, 47 USPQ2d 1523, 1528 (Fed. Cir. 1998) (“With direct review by this court of the Board's reexamination decisions, a patentee can be certain that it cannot be subjected to harassing duplicative examination.”); see also Heinl v. Godici, 143 F. Supp. 2d 593, 597-598 (E.D. Va. 2001).

All Rejected Claims Treated as Appealed
Note:
If fewer rejected claims are identified in the appeal, all pending rejected claims are treated as appealed unless appellant has overcome a rejection.

In addition, examiners are not required to make any determination whether fewer than all of the rejected claims are identified by the appellant as being appealed. If the notice of appeal or appeal brief identifies fewer than all of the rejected claims as being appealed, the issue will be addressed by the Board panel. Therefore, the examiner will treat all pending, rejected claims as being on appeal, and the examiner must maintain all of the rejections set forth in the Office action from which the appeal is taken, unless appellant has overcome the rejection (e.g., by submitting persuasive arguments, an acceptable terminal disclaimer, or evidence). In situations where the appellant makes a request to hold a rejection in abeyance or did not present any argument on a rejection in the appeal brief, the examiner should maintain the rejection in the examiner’s answer.

CRU Retains Jurisdiction Over Appeal Brief and Amendments After Final
Note:
The CRU retains jurisdiction to consider appeal briefs, conduct conferences, draft examiner’s answers, and decide on amendments and evidence after final or notice of appeal. Petitions concerning refusal to enter amendments/evidence are delegated.

The responsibility of the Board for determining whether appeal briefs comply with 37 CFR 41.37 is not considered a transfer of jurisdiction when an appeal brief is filed, but rather is only a transfer of the specific responsibility of notifying appellants under 37 CFR 41.37(d) of the reasons for non-compliance. The CRU retains the jurisdiction over the reexamination proceeding to consider the appeal brief, conduct a conference, draft an examiner’s answer, and decide the entry of amendments, evidence, and information disclosure statements filed after final or after the filing of a notice of appeal. Furthermore, petitions concerning the refusal to enter amendments and/or evidence remain delegated as per MPEP §§ 1002.02(b) and 1002.02(c). The jurisdiction of the ex parte reexamination proceeding is transferred to the Board when a docketing notice is entered after the time period for filing a reply brief expires or the examiner acknowledges the receipt and entry of the reply brief.

Distinguish Between No Argument and Unconvincing Arguments in Appeal Brief
Note:
The rule requires distinguishing between the absence of arguments and the presentation of unconvincing arguments in an appeal brief, with grounds for rejection summarily sustained only if no argument is presented.

It is to be noted that the mere filing of any paper whatsoever entitled as a brief cannot necessarily be considered as compliance with 37 CFR 41.37. The rule requires that the brief must set forth the authorities and arguments relied on, and to the extent that it fails to do so with respect to any ground of rejection, that ground may be summarily sustained. A distinction must be made between the lack of any argument and the presentation of arguments that carry no conviction. In the former case summarily sustaining the rejection is in order, while in the latter case a decision on the merits is made, although it may well be merely an affirmance based on the grounds relied on by the examiner.
