Why Your Patent Was Rejected — What Office Actions Soften Between the Lines
2026-06-23
← Back to BlogLast year I was rejected twice — once utility model, once invention. The first office action felt like nitpicking; the second time I saw the examiner was right. Notices soften wording; you must learn to read it.\n\nThe logic is simple: the examiner cites one or more references, compares them to your claims, and asks whether the difference is large enough for inventive step. If not, rejection.\n\nDetails they will not spell out:\n\n1) Inventive step is partly subjective. Obvious to a person skilled in the art has no single meter. Argue different technical problems and effects when structure looks similar — I did that against a US reference about heat dissipation while my invention was about sealing, and it worked.\n\n2) Examiner search bias. Cross-IPC inventions may be searched in only one familiar class. Point out missing electronic-control features when citations are all mechanical.\n\n3) Challenge common knowledge assertions. Ask for textbook, handbook, or standard support.\n\n4) Deadlines matter and extensions exist (paid). Do not rush a weak response.\n\n5) Do not fight the examiner personally. Admit what the reference discloses, isolate what it does not, state the technical effect of the difference, and explain why that difference is not obvious.\n\nA rejection decision is not the end — reexamination is available and often more panel-based. Still, many cases can be fixed at the response stage with careful problem/effect arguments.
