Find the page that matches what your Office Action actually says

Every kind of USPTO Office Action explained separately: 101, 102, 103 and 112 rejections, final actions and restriction requirements.

Office Actions are not interchangeable. A §103 obviousness rejection, a §112 indefiniteness rejection and a restriction requirement are answered in different ways, on different timetables, with different chances of success. Start from the section numbers the examiner cited in your document — they appear in bold headings such as “Claim Rejections – 35 U.S.C. § 103” — and read the page for that ground.

Which of these pages is about my document?

Look at the bold headings in your Office Action. The examiner is required to identify the statutory basis for every rejection, so the headings contain the section numbers. Most actions contain more than one.

By ground of rejection

If the action says	The examiner is arguing	Read this
35 U.S.C. § 101	The subject matter is not eligible for patenting at all	101 rejection
35 U.S.C. § 102	One earlier document already discloses the whole claim	102 rejection
35 U.S.C. § 103	A combination of earlier documents makes the claim obvious	103 rejection
35 U.S.C. § 112	The claims are unclear, or the description does not support them	112 rejection
FINAL in the heading	Your options for what you may file are now restricted	Final Office Action
Restriction or election required	The application covers separate inventions; pick one	Restriction requirement

Questions people ask

Yes, and most do. It is common to see a §103 obviousness rejection of the independent claims, §112(b) indefiniteness objections to particular terms, and formal objections to the drawings, all in the same document. A reply has to address every one of them.

It depends on your claims rather than on the section number. A §112(b) objection to unclear wording is usually fixable by amendment. A §101 eligibility rejection can require rethinking what is claimed. A §103 rejection turns on whether the examiner’s combination of references holds up.
