Patent Office Actions: The Must-Have Guide to Responses
Filing a patent application is only the first step toward receiving a registered patent. Next, the USPTO assigns a Patent Examiner to review and analyze the patent…

[01]Who it's for
For applicants with a rejection on their desk.
Most people who call us about an office action have one date in mind, the deadline. We start with what the examiner actually said, then what it will take to move the application toward allowance.
Inventors who filed on their own
A first rejection on an application you wrote yourself, and a response that has to keep the scope you need.
Software and AI applicants
Section 101 eligibility rejections, often next to prior art, answered with the technical detail already in your application.
Applications filed by another firm
We review the file history and the examiner's reasoning before we pick up the response.
Device and hardware companies
Prior art and obviousness rejections, answered with amendments that still cover the product you make.
Industries we prosecute in
[02]What a response does
What a response can do, and what it cannot.
A response is your written reply to the examiner. It has to answer every ground of rejection and objection, and it can only work with what your application already discloses.
Office action responses on utility applications are quoted flat at $2,500 to $3,500 per response. Design patent and trademark flat fees already include every office action.
A response can
- Show the examiner misread the prior artPoint to what the cited references actually teach, and what your claims require that they do not.
- Amend the claimsNarrow or clarify claim language using what your application already describes.
- Add evidenceA sworn declaration with test data, commercial results or an engineer's analysis can answer an obviousness or enablement rejection.
- Settle issues on an interviewA call with the examiner can narrow the dispute before the written response is filed.
A response cannot
- Add new matterNothing new can be added to the application after filing. Amendments have to find support in what you filed.
- Skip a groundEvery rejection and objection needs an answer, or the reply can be treated as incomplete.
- Stop the clockA late reply abandons the application unless it is revived.
- Reopen everything after a final rejectionAfter a final rejection, amendments are limited. A broader change needs an RCE, a continuation or an appeal.
- Take back what an amendment gives upNarrowing a claim to get it allowed can limit how far it reaches against a competitor later.
- Promise an allowanceNo one can promise what an examiner will do. We tell you the options and the trade-offs of each.
[03]Types
What kind of office action did you get?
Every USPTO letter that needs a reply sets a deadline, and the deadline depends on the type. The type is printed on the first page of the action.
| Action | What it means | Reply period |
|---|---|---|
| Restriction requirement | The examiner found more than one invention in your claims. You pick one group to examine now, and the others can go into a divisional application. | 2 months, extendable |
| Non-final rejection | The first full review of your claims, with rejections, objections or both. | 3 months, extendable to 6 |
| Final rejection | The examiner was not persuaded by your last reply, and your options narrow. | 3 months, extendable to 6 |
| Advisory action | The examiner's answer to a reply after a final rejection. It says whether an amendment was entered. | No new period. The final rejection deadline keeps running |
| Ex parte Quayle action | The claims are allowable and only matters of form remain. | 2 months, extendable |
| Notice of allowance | The application is allowed and the issue fee is due. | 3 months, not extendable |
Extensions are bought one month at a time, and no reply period runs past six months from the date of the action. The extension fees are further down this page.
[04]Rejections
101, 102, 103 and 112 rejections, and how each one is answered.
The rejection cites a section of the Patent Act. That number tells you what the examiner thinks is wrong, and it points to the kind of answer that can work.
| What the examiner is saying | How a response usually answers it | |
|---|---|---|
| Section 101, eligibility | The claim is directed to an abstract idea, law of nature or natural phenomenon, without adding significantly more. Common for software, AI and diagnostics. | Amend the claims to recite the technical improvement the application describes, and explain why the claim as a whole is not abstract under USPTO guidance. |
| Section 102, novelty | One prior reference already discloses every element of the claim. | Show an element the reference does not disclose, or amend the claim to add one the application supports. |
| Section 103, obviousness | A person skilled in the field would have combined the cited references to reach the claim. | Show a missing element, no reason to combine, or that the combination would not work as claimed. Evidence like unexpected results can help. |
| Section 112(a), written description and enablement | The application does not show you had the claimed invention, or does not teach how to make and use it. | Point to where the specification supports the claim, or narrow the claim to what it does support. |
| Section 112(b), definiteness | A claim term is unclear, so the boundaries of the claim are uncertain. | Clarify the wording, or explain how a skilled reader would understand the term from the specification. |
| Double patenting | The claim is not distinct enough from claims in another of your own patents or applications. | Argue the claims are distinct, amend them, or file a terminal disclaimer that ties the two patents' terms and ownership. |
Software and AI rejections often pair Section 101 with prior art. For a full walk-through of eligibility responses, see overcoming the 101 rejection, and for double patenting, what a double patenting rejection is.
[05]How we work
Responses written around the product you sell.
We read the whole file first
Before we draft anything, we read the office action, every cited reference, your claims and specification, and any earlier replies. Then we tell you which rejections are strong, which are not, and what each response route would cost in claim scope.
We talk to the examiner
An interview often resolves in a call what would take another round in writing. We request one when it can narrow the issues, usually with proposed claim language in hand. Interviews can be held by phone or video.
Amendments that still cover your product
Independent claims set how far your protection reaches. Dependent claims add detail. When an amendment is needed, we look for the smallest change that gets past the art, and we keep at least one claim that reads on what you actually make and sell.
Evidence and case law
Where a rejection turns on facts, we prepare declarations with test results or technical analysis. Where it turns on the law, we cite the Federal Circuit decisions and USPTO guidance that apply to your kind of claim.
Software and AI rejections
Section 101 rejections are common for software and machine learning claims. We answer them with the technical improvement already described in your application. See how software patent office actions work and our software patent attorneys.
Tools help. An attorney reads every reference.
Search and AI tools can sort and summarize cited prior art quickly. They do not replace a registered patent attorney reading each reference against your claims, which is where the arguments come from.
What to send us before your call
- The office action itself, or your application number
- The cited references, if you have them
- What your product does today and how it differs from what the examiner cited
- Any test data, sales or industry recognition that shows the invention works or succeeded
- Your deadline, and whether any extension has been paid

[06]Non-final vs final
Non-final vs final office action. What changes?
A final rejection does not end the application. It closes the easy path. After a final rejection you can no longer amend as a matter of right, so the response has to choose a route.
| Non-final office action | Final office action | |
|---|---|---|
| Amending the claims | Allowed, as long as the application supports the change | Limited to cancelling claims, fixing form, or changes that place the case in condition for allowance or in better form for appeal |
| New evidence | Can be filed with the reply | Limited, and usually needs an RCE to be considered |
| Reply period | 3 months, extendable to 6 | 3 months, extendable to 6. Reply within 2 months to protect the deadline while you wait for the advisory action |
| Examiner interview | Available on request | Normally one interview after final, to resolve issues or reach allowance |
| If issues remain | Another action, which may be made final | An RCE, a continuation or an appeal to the PTAB |
[07]After final
Your options after a final rejection.
There are four routes, and some can be combined. The right one depends on how far apart you and the examiner are, and on what the claims need to cover.
An after-final reply
If the remaining issues are small, a reply that cancels claims or rewrites them into allowable form may be entered. The examiner answers with an advisory action. If you reply within two months of the final rejection and the advisory action comes after the three-month date, the period runs to the advisory action, which can save extension fees.
What happened to AFCP?
The After Final Consideration Pilot let examiners spend a little extra time on after-final amendments. The USPTO let it expire, and the last day to request it was December 14, 2024. Requests filed after that date are not considered.
A request for continued examination (RCE)
An RCE reopens prosecution. You can file new claim amendments, new arguments and new evidence, and the examiner considers them as a new round. The USPTO fee is $1,500 for the first RCE ($600 for a small entity, $300 for a micro entity) and $2,860 for each one after that.
A continuation application
A continuation keeps your original filing date and lets you pursue different claims, as long as it is filed while the parent application is still pending. It is a way to take allowed claims now and keep arguing for broader ones. More on patent continuations.
An appeal to the PTAB
Once any claim has been rejected twice, you can appeal to the Patent Trial and Appeal Board. You file a notice of appeal, then an appeal brief within two months, and a panel of judges decides whether the examiner was right. The USPTO fee for the notice of appeal is $905, or $362 for a small entity and $181 for a micro entity. An appeal makes sense when the disagreement is about the law or what the prior art teaches, not about wording.
[08]The flat-fee path
One flat fee for each response.
Every response is quoted flat before any work begins, so you know the cost before you decide which route to take. USPTO fees, such as extension, RCE or appeal fees, are separate.

[10]Deadlines
How long do you have to respond to an office action?
Usually three months from the date on the action. You can extend that by up to three more months by paying a USPTO extension fee, but never past six months. Miss it, and the application is abandoned.
| Reply filed in | USPTO fee | Small entity | Micro entity |
|---|---|---|---|
| First extra month | $235 | $94 | $47 |
| Second extra month | $690 | $276 | $138 |
| Third extra month | $1,590 | $636 | $318 |
These are government fees from the USPTO fee schedule effective January 19, 2025, and they are paid on top of the response fee. The fee is set by the month the reply is filed in, so filing early in an extension month costs the same as filing on its last day.
A restriction requirement or an Ex parte Quayle action sets a two-month period instead. A notice of allowance gives three months to pay the issue fee, and that date cannot be extended.
[11]Avoid these
Five mistakes that weaken an office action response.
A weak response can still get a patent allowed, just a narrow one that a competitor can design around. Each of these is avoidable.
- Waiting until the last week. The interview, the claim strategy and your review all take time. Extension fees also rise each month.
- Answering the label, not the reasoning. The examiner's explanation shows exactly which claim elements and references are the problem. A reply that misses one ground can be held incomplete.
- Amending more than the rejection needs. Every narrowing amendment gives something up. Add only what distinguishes the prior art, and keep at least one claim on the product you sell.
- Arguing without evidence. When obviousness or enablement turns on facts, a declaration with test data or an engineer's analysis carries more weight than argument alone.
- Arguing more than you need. Statements made to the examiner become part of the public record and can be used to read your claims narrowly later.
[12]Questions
Questions about office actions.
Have an office action with a deadline? Your first call is free and comes with a straight answer on your options.
Book A Free Strategy CallWho can respond to a complex office action?
The inventor named as the applicant can respond on their own, or a registered patent attorney or patent agent can respond for them. Companies, and applicants based outside the US, must be represented by a registered patent practitioner. For a complex action with prior art, Section 101 or 112 rejections, a registered patent attorney is usually the safer choice, because the arguments and amendments made now shape what the patent will cover.
What is a patent office action?
It is a written letter from the USPTO examiner reviewing your application. It lists any rejections of your claims and objections to the application, with the reasons and the prior art relied on, and sets a deadline to reply. Restriction requirements, non-final rejections and final rejections are all office actions.
Does an office action mean my patent was rejected?
No. It means the examiner has concerns that need an answer before the claims can be allowed. Many applications are allowed after one or more rounds of responses and amendments.
How long do I have to respond to a patent office action?
Usually three months from the date on the action. You can extend it month by month, up to six months in total, by paying a USPTO extension fee. Restriction requirements and Ex parte Quayle actions set two months. If no reply is filed in time, the application is abandoned.
How much does an office action response cost?
For a utility application, $2,500 to $3,500 per response, quoted flat before any work begins. Office actions on design patents and trademarks are already included in those flat fees. USPTO fees, such as extension, RCE or appeal fees, are extra when they apply.
What is the difference between a non-final and a final office action?
A non-final action is usually the examiner's first full review, and you can amend the claims freely as long as the application supports the change. A final action means the examiner was not persuaded, and amendments are then limited. After a final rejection the main routes are an after-final reply, an RCE, a continuation or an appeal.
Can I talk to the patent examiner?
Yes. Examiner interviews by phone or video are a normal part of examination and are often the fastest way to narrow a dispute. After a final rejection, one interview is normally permitted.
What is a request for continued examination (RCE)?
An RCE reopens prosecution after a final rejection, so the examiner considers new amendments, arguments and evidence. The USPTO fee is $1,500 for the first request, or $600 for a small entity and $300 for a micro entity.
Should I appeal a final rejection?
Sometimes. An appeal to the Patent Trial and Appeal Board fits when the disagreement is about the law or what the prior art teaches, and amending would give up scope you need. You can appeal once any claim has been rejected twice. Your attorney compares it with an RCE or a continuation on your strategy call.
What are an advisory action and an Ex parte Quayle action?
An advisory action is the examiner's reply to a response after a final rejection, saying whether an amendment was entered. It does not give you a new deadline. An Ex parte Quayle action means the claims are allowable and only matters of form remain, with two months to fix them.
What happened to the After Final Consideration Pilot (AFCP)?
The USPTO let the AFCP 2.0 program expire. The last day to request it was December 14, 2024. After-final replies are now handled under the standard rules, or by filing an RCE.
Are office action responses covered by The RLG Guarantee?
Office action responses on utility applications are not covered. Design patents and trademarks are covered matters, and their flat fees already include every office action. Refunds are subject to the RLG Guarantee Policy in your engagement letter.
