An office action is a letter from the examiner. It says which claims are rejected and why, which parts of the application are objected to, and how long you have to reply. The first one is almost always some kind of no.
That is not a verdict on your invention. It is the opening position in a negotiation over how broad your claims get to be. Most applications receive at least one rejection. What matters is reading the action correctly and responding with discipline.
First, the Deadline
Find the mailing date and the period for reply first. Office actions usually set a shortened statutory period of three months, extendable in one-month steps to six months from the mailing date, with fees that escalate each month. After that the application is abandoned. Revival by petition is possible for unintentional delay, but it is not guaranteed.

Rejections, Objections, and Requirements
The action will contain some mix of three things. Rejections say a claim is not patentable under a section of the statute; these are the substance. Objections point to formal problems, such as a drawing that fails the rules; they are fixable and rarely change the outcome. Requirements ask you to do something, most often to elect one invention for examination when the examiner finds more than one; the rest can go in a divisional application.
The action is either non-final or final. A non-final action allows amendment as of right; a final action limits what can be entered without reopening prosecution. The first action is almost always non-final.
The Four Rejections You Will See
Each cites a section of Title 35 of the United States Code. In plain words:
Section 101: not the kind of thing patents cover, as claimed. The examiner says the claim is directed to an abstract idea, a law of nature, or a natural phenomenon without significantly more. This is the common rejection for software, AI, diagnostics, and business methods. The fix is usually to claim the specific technical mechanism rather than the result, which only works if the specification described it. Are AI Inventions Patentable? walks through the distinction.
Section 102: someone already described exactly this. Anticipation. A single reference, whether a patent, a paper, or a product, shows every element of the claim arranged as claimed. The response either shows an element the reference lacks or amends the claim to add one.
Section 103: no single reference has it all, but combining known pieces would have been obvious. The examiner cites two or more references and a reason a person of ordinary skill would have combined them. This is the most common rejection, and technical knowledge decides it: whether the references really teach what the examiner says, whether there was a reason to combine them, and whether the result was unexpected.
Section 112: the claim or the description is not clear enough or not supported enough. Under 112(a), the specification does not describe or enable what the claim covers. Under 112(b), the claim itself is indefinite: a term with no antecedent basis, a word with no fixed meaning. Indefiniteness is usually a wording fix. Lack of support is harder, because new matter cannot be added after filing.
What a Response Does
A response is a written reply that addresses every rejection and objection in the action. It has three tools.
Argument. Explaining, with reference to the cited documents, why the rejection is wrong: the reference lacks the element, the combination has no motivation, the claim recites a specific technical improvement rather than an abstract idea.
Amendment. Changing the claim language, usually by adding a limitation the prior art lacks. Every amendment must be supported by the specification as filed, and every amendment is permanent. Narrowing to get past one reference can surrender coverage you needed, so choose a limitation a competitor cannot easily avoid.
Evidence. A declaration under 37 CFR 1.132 can put facts in the record: test results, unexpected outcomes, commercial success tied to the claimed feature.
An examiner interview, before or after the response, is often the most efficient step. A short call can settle what two written rounds would not, because the examiner can say what language they would allow.
The goal is not to overcome the rejection. It is to overcome the rejection with claims that still cover what a competitor would build. Those are different goals, and only the second one matters commercially.
What to Send Your Attorney
Your attorney knows the law and the examiner. You know the technology and the market better than either of them. Send the following as soon as the action arrives, not the week before the deadline:
- Your own reading of each cited reference: what it actually does and where it differs from what you built, in terms of mechanism rather than purpose.
- Features in your application that distinguish you from the references but were never claimed. These are the amendment candidates.
- What the product ships as today, and what competitors ship. Amendments should stay on what the market actually uses.
- Any data: test results, comparisons, alternatives that failed, industry reactions tied to the claimed feature.
- Any prior art you have become aware of, including your own papers and releases. The duty of disclosure under 37 CFR 1.56 continues through prosecution.
- Your priorities. Which claims matter most to the business, and how much narrowing you can live with.
Two things not to do: contact the examiner yourself if you are represented, or treat the first action as a reason to stop. Abandoning after a first rejection is the most common way a workable invention ends up unprotected.
After a Final Rejection
If the second action is final and the claims are still rejected, there are three paths: an after-final response, if the amendments are small enough to be entered; a request for continued examination, which reopens prosecution for a fee; or an appeal to the Patent Trial and Appeal Board, which is slower but the right path when the examiner is wrong on the merits. Choosing among them is a judgment about the examiner, the art, and the budget. Continued examination is routine, not a sign of failure.
The Short Version
Read the deadline first, then the rejections. Section 101 is about eligibility, 102 about a single reference, 103 about combinations, 112 about clarity and support. A response argues, amends, or adds evidence, and the discipline is to overcome the rejection without giving up the coverage that made the patent worth filing. Send your technical read of the references early, and keep the deadlines somewhere other than your memory.

Frequently Asked Questions
Is it normal to get a rejection on a patent application?
Yes. Most applications receive at least one rejection in the first office action. The examiner's job is to test the claims against the prior art, and the first action is where the negotiation over claim scope begins.
How long do I have to respond to an office action?
Most office actions set a shortened statutory period of three months from the mailing date, extendable to six months with fees that escalate each month. After six months the application is abandoned.
What is the difference between a 102 rejection and a 103 rejection?
A section 102 rejection says a single prior art reference shows every element of the claim. A section 103 rejection says the claim would have been obvious from a combination of references. Section 103 is more common, and technical argument matters most there.
What is a final office action?
A final action limits the amendments that can be entered as of right. After it you can file an after-final response, request continued examination to reopen prosecution, or appeal to the Patent Trial and Appeal Board. It does not mean the application is over.
