A patent drawing service or patent illustration service bills per figure and per revision, with published 2026 rates from $25 to $300 a figure. Here is what patent drawing services include, how to evaluate one, and when software does the job the same day.

Published rates cluster into three tiers — and revisions are usually billed on top.
Fine for simple flowcharts and block diagrams; quality varies.
The typical professional tier; design sheets price at the top.
Complex mechanical, medical, and litigation-grade work.
One or two minor rounds included, then the meter restarts.
Rush delivery typically adds a 20–50% premium.
Five to ten figures at quality rates, before any corrections.
Five questions that separate good providers from cheap ones.
Do they know USPTO 37 CFR §1.84 — and EPO, CNIPA, JPO, KIPO, PCT if you file abroad?
Will reference numerals stay consistent across every view?
How many rounds are included, and what does round three cost?
If the examiner objects, what do replacement sheets cost and how fast?
Can they work from your photos, sketches, or CAD exports?
The honest comparison — services sell expertise per figure; software sells unlimited iteration.
