Patent Office Action Types

Every USPTO communication from non-final to Notice of Allowance — and how to respond.

Quick Answer

USPTO office actions fall into six main types: non-final rejection (full leverage to argue and amend), final rejection (limited response options), restriction requirement (must elect one invention), advisory action (after-final status update), Notice of Allowance (pay issue fee within 3 months), and abandonment notice (petition to revive).

Office Action Reference

All USPTO Office Action Types

Non-Final Office Action (NFOA)

PTOL-326

When issued: First substantive examination; after RCE; after PTAB remand

Response deadline: 3 months (extendable to 6 months with fees)

Full leverage — examiner must consider all arguments and amendments

Argue against rejectionsAmend claimsFile declarations (e.g., §1.132 affidavit)Request examiner interviewAbandon or file continuation

Final Office Action (FOA)

PTOL-326 (Final)

When issued: After applicant responds to NFOA and rejections are maintained

Response deadline: 2 months shortened statutory period (extendable)

Limited leverage — examiner not required to enter amendments or fully respond

Appeal to PTAB (Notice of Appeal)File RCE (Request for Continued Examination)After-final amendment (examiner discretion to enter)Request AFCP interviewFile continuation application

Restriction Requirement

PTOL-821

When issued: Early examination — when application claims multiple distinct inventions

Response deadline: 1 month (extendable to 6 months with fees) — must elect group

Neutral — applicant chooses which claims to pursue; non-elected claims must be divided

Elect one group (required)Traverse restriction (argue inventions are not distinct)File divisional applications for non-elected groups

Advisory Action

PTOL-303

When issued: After applicant's reply to final office action

Response deadline: Depends on whether amendment was entered

Informational — tells applicant whether after-final amendment was entered

Proceed with appeal if amendment not enteredFile RCE if amendment not entered but desiredPay issue fee if examiner signals allowance

Notice of Allowance (NOA)

PTOL-85

When issued: When examiner determines all claims are allowable

Response deadline: 3 months to pay issue fee (non-extendable)

Positive — examiner has accepted claims; next step is paying the issue fee

Pay issue fee (patent issues)File RCE before paying issue fee to continue prosecutionFile continuation/CIP before issue date

Notice of Abandonment

PTOL-1432

When issued: When applicant misses response deadline or abandons

Response deadline: Petition to revive (2 months; 'unintentional' standard for recent abandonments)

Negative — application abandoned; revival possible with petition + fees

Petition to revive (37 C.F.R. § 1.137)Accept abandonment; file new application if not too much time has passed

Prosecution Flow

Typical Office Action Sequence

Most U.S. patent applications go through a predictable sequence, though variation is common — especially after RCEs:

Filing → examiner assigned → 18 months → publication
Non-Final Office Action (1st) → applicant responds within 3 months (or extends)
Non-Final Office Action (2nd) — OR — Final Office Action (if rejections maintained)
If final: RCE filed → prosecution re-opens → new Non-Final
Notice of Allowance → issue fee paid within 3 months → patent issues

FAQ

What is a non-final office action?

A non-final office action (NFOA) is the examiner's first substantive response to the application's claims. It may include § 101 subject matter rejections, § 102 novelty rejections, § 103 obviousness rejections, § 112 rejections (written description, enablement, definiteness), and/or objections to the specification, drawings, or abstract. The applicant has 3 months (extendable to 6 months with fees) to respond. Because it is non-final, the examiner must consider the applicant's full response — including new arguments, claim amendments, and declarations. A non-final action is an opportunity to argue back with full leverage.

What is a final office action?

A final office action (FOA) is issued after the applicant has responded to a non-final office action and the examiner determines that the remaining rejections are maintained. After a final rejection, the applicant's options are limited: (1) appeal to the PTAB; (2) file a Request for Continued Examination (RCE) to re-open prosecution; (3) file a continuation application; (4) file an after-final amendment (which the examiner may or may not enter); or (5) request an After-Final Consideration Pilot (AFCP) program interview. The 2-month shortened statutory period begins after a final rejection. The key limitation: the examiner is not required to enter amendments after final.

What is a restriction requirement?

A restriction requirement (37 C.F.R. § 1.142) is issued when the examiner determines that the application claims two or more independent and distinct inventions. Only one invention may be prosecuted per application (35 U.S.C. § 121). The examiner designates groups and requires the applicant to elect one group for prosecution. The non-elected claims are withdrawn and must be pursued in divisional applications to receive patent protection. Restriction requirements are common in multi-species applications (various chemical compounds), applications with both product and method claims, and applications with multiple embodiments.

What is an advisory action?

An advisory action (PTOL-303) is issued by the examiner in response to an applicant's reply to a final office action. It informs the applicant whether amendments submitted after final will be entered and considered. An advisory action is typically issued when the examiner determines the after-final amendment does not place the application in condition for allowance or raise a new issue. The advisory action is important for timing — it establishes whether the submission has been entered and how that affects the shortened statutory period. Filing an RCE (Request for Continued Examination) before the advisory action deadline resets the prosecution cycle.

What happens after a Notice of Allowance?

After a Notice of Allowance (NOA, Form PTOL-85), the applicant has 3 months to pay the issue fee. If the issue fee is not paid, the application becomes abandoned. The applicant can file a Request for Continued Examination (RCE) before paying the issue fee to continue prosecution (useful if broader claims are desired). After paying the issue fee, the patent issues within weeks. A continuing application (continuation or CIP) must be filed before the patent issues to maintain an active child application in the family.
