Nobody will tell me a number before a consultation.
The reason is real — the work genuinely varies — but the ranges are knowable, and refusing to state them mostly wastes your time.
So: the bands below, what moves a case between them, and which fees are the government’s rather than a professional’s. A firm quote needs the document, because the document determines the scope.
Indicative bands
straightforward
$1,200–$2,500
One or two grounds, few claims, no examiner interview expected.
moderate
$2,500–$4,500
Multiple grounds or several independent claims, amendments likely.
complex
$4,500–$8,000
Final action, many references, or claim strategy needs rework.
Indicative professional fees only, in USD. USPTO fees are set by regulation and are charged separately.
What moves a case up a band
The number of distinct grounds of rejection. Each one has to be answered separately, and a §101 rejection alongside §103 is close to two pieces of work.
How many independent claims are affected, and whether the dependent claims can follow them or need individual treatment.
How many references were cited, and whether they have to be read in full to answer the mapping.
Whether the action is final, which forces a choice between an after-final reply, an RCE and an appeal.
Whether evidence is needed — a declaration of unexpected results or a prior-disclosure declaration is real additional work.
How much time is left. Compressed timetables cost more everywhere, in every profession.
USPTO fees are separate
Official fees are set by regulation, change periodically, and depend on entity size — large, small, or micro. An extension of time, an RCE, a notice of appeal and excess claim fees are all charged by the USPTO in addition to any professional fee. Always check the current fee schedule rather than a figure quoted on a website, including this one.
