11.1 Ex Parte Appeals to the PTAB

Ex parte appeal practice before the Patent Trial and Appeal Board (PTAB) provides an administrative remedy for patent applicants seeking to contest an examiner's rejection of claim subject matter. Governed by MPEP Chapter 1200 and 37 C.F.R. Part 41, ex parte appeals allow applicants to transition an impasse with the examining corps to a panel of administrative patent judges (APJs). Understanding the strict procedural benchmarks, statutory deadlines, fee structures, and brief formatting rules is critical for the Patent Bar Examination.

Notice of Appeal Thresholds & Timing (37 C.F.R. § 41.31)

Under 35 U.S.C. § 134 and 37 C.F.R. § 41.31, an applicant may file a Notice of Appeal to the PTAB only after any of the claims in an application have been twice rejected or after a Final Rejection has been issued.

Key Prerequisites and Statutory Rules:

• Twice Rejected Rule: The claims do not need to be rejected twice in the same office action, nor do they need to be rejected twice under the exact same statutory provision. A rejection of a claim in a non-final office action followed by a rejection of that same claim (or a modified version) in a subsequent office action satisfies the twice-rejected threshold.
• Final Rejection Trigger: Filing a Notice of Appeal is the primary mechanism to maintain pendency after a Final Office Action without amending claims or filing a Request for Continued Examination (RCE) under 37 C.F.R. § 1.114.
• Filing Fee & Signature: The Notice of Appeal must be accompanied by the statutory fee set forth in 37 C.F.R. § 41.20(b)(1) and signed in accordance with 37 C.F.R. § 1.33.
• Time Period for Filing: The Notice of Appeal must be filed within the statutory period set for response to the Office Action (typically 3 months from the mailing date of a Final Rejection, extendable up to 6 months under 37 C.F.R. § 1.136(a)).

Pre-Appeal Brief Conference Pilot Program

Prior to preparing a full Appeal Brief, an applicant may file a Request for Pre-Appeal Brief Conference concurrently with the Notice of Appeal.

• Requirements: The request must be filed on the same date as the Notice of Appeal and accompanied by a concise (5 pages or fewer) statement presenting arguments highlighting clear errors in factual findings or legal conclusions.
• Panel Composition: A panel of three examiners (including the primary examiner and a supervisory patent examiner) reviews the application.
• Possible Outcomes:
  1. Prosecution Reopened: The rejection is withdrawn and prosecution resumes.
  2. Application Allowed: The application is passed to issue.
  3. Appeal Should Proceed: The panel determines that appeal issues remain, requiring the applicant to file an Appeal Brief within the statutory time frame.
  4. Dismissed: If the request fails to comply with formatting rules (e.g., exceeds 5 pages).

Appeal Brief Requirements (37 C.F.R. § 41.37)

Once a Notice of Appeal is filed, jurisdiction remains with the examining corps until an Examiner's Answer is entered and the Board takes jurisdiction. The applicant must file an Appeal Brief under 37 C.F.R. § 41.37 to avoid abandonment of the appealed claims.

Deadlines & Extensions:

• Time Frame: The Appeal Brief is due within 2 months from the date of receipt of the Notice of Appeal by the USPTO.
• Extensions of Time: The 2-month deadline for filing the Appeal Brief is extendable by up to 5 months under 37 C.F.R. § 1.136(a) (subject to the absolute statutory 6-month deadline from the underlying office action mailing date if the Notice of Appeal was filed early).

Mandatory Contents & Section Order:

Under 37 C.F.R. § 41.37(c), an Appeal Brief must contain the following required headings in precise order:

1. Real Party in Interest: Must identify the real party in interest. If unassigned, state the inventors.
2. Related Appeals, Interferences, and Derivations: Identify all other prior and pending appeals, interferences, derivations, or judicial proceedings that may be affected by or have a bearing on the Board's decision.
3. Summary of Claimed Subject Matter: An explicit mapping of each appealed independent claim (and dependent claims if argued separately) to the specific structures, steps, or material disclosed in the specification by page/line number or paragraph reference.
4. Claims Standing Allowed or Objected To: A statement indicating the status of all claims in the application.
5. Arguments: Concise, separate argument headings for each rejection under each statutory provision (35 U.S.C. § 101, § 102, § 103, § 112).
6. Claims Appendix: A clean, exact copy of all appealed claims attached as an appendix.

Rules of Claim Grouping:

• Claims Stand or Fall Together: Unless the applicant explicitly argues dependent claims separately under separate sub-headings in the Arguments section, all claims within a rejected group will stand or fall together with the representative claim selected by the Board.
• Separate Sub-headings Required: To preserve individual review for dependent claims, the applicant must clearly state that specific claims do not stand or fall together and provide distinct legal and factual reasons why that dependent claim is patentable over the cited prior art.

Examiner's Answer & New Grounds of Rejection (37 C.F.R. § 41.39)

Upon receipt of the Appeal Brief, the primary examiner conducts an initial review and may take one of three actions:

1. Reopen prosecution (with Supervisory Patent Examiner approval).
2. Withdraw the rejection and pass the application to allowance.
3. Prepare an Examiner's Answer maintaining the rejections under 37 C.F.R. § 41.39.

Designated New Grounds of Rejection:

Under 37 C.F.R. § 41.39(a)(2), the examiner may include a new ground of rejection in the Examiner's Answer only with the prior approval of the Supervisory Patent Examiner (SPE) or Technology Center Director.

When an Examiner's Answer contains a designated new ground of rejection under § 41.39(b), the applicant has two mutually exclusive options exercisable within 2 months (non-extendable under § 1.136(a)):

• Option 1: Reopen Prosecution: File a response under 37 C.F.R. § 1.111 with or without amendments or evidence. Prosecution is reopened before the primary examiner, and the appeal is terminated.
• Option 2: Maintain Appeal (File Reply Brief): File a Reply Brief under 37 C.F.R. § 41.41 addressing only the new grounds of rejection. The appeal proceeds to the Board for adjudication.

Reply Briefs & Oral Hearing Requests

Reply Brief (37 C.F.R. § 41.41):

• Deadline: The applicant may file a Reply Brief within 2 months of the mailing date of the Examiner's Answer.
• Extensions: Non-extendable under 37 C.F.R. § 1.136(a); requires a showing of good cause under § 1.136(b).
• Scope: Must be limited to points raised in the Examiner's Answer. No new evidence or claim amendments may be submitted with a Reply Brief without Board permission.

Request for Oral Hearing (37 C.F.R. § 41.47):

• Filing Window: Written request filed within 2 months from the date of the Examiner's Answer.
• Fee: Accompanied by the statutory oral hearing fee specified in 37 C.F.R. § 41.20(b)(3).
• Scope of Argument: Oral argument is strictly limited to issues and arguments raised in the Appeal Brief and Reply Brief. No new evidence or arguments may be introduced during the hearing.
