How much do patent drawing services cost?

Most drafting services quote per sheet, and design patent sheets cost more than utility sheets. A typical utility set has 5 to 10 sheets, so ask for a quote for the whole set, including revisions. On PatentStroke a drawing or diagram costs 10 credits, and one application starts at $39.9 for 300 credits.

How long does a patent drawing service take?

Usually several business days for a utility set and longer for design patents, with rush delivery at extra cost. PatentStroke draws a line drawing in about 15 seconds and a flowchart or block diagram in about a minute; your review is the slow part.

Is PatentStroke a patent drawing service?

No. PatentStroke is self-serve software: you make, edit and review the drawings yourself, and nobody draws them for you. Check every sheet before filing, or ask your attorney to.

Can I combine a drafting service and PatentStroke?

Yes. Many applicants make most figures in PatentStroke and send one or two difficult views to a drafter. Share a read-only link to the sheet set so everyone works from the same drawings.

Will the USPTO accept the drawings?

PatentStroke lays sheets out to 37 CFR 1.84: margins, black and white, FIG. labels, sheet numbers and text height. No tool or service can promise acceptance, because the examiner decides; review each sheet against the requirements before filing.

Drafting service or self-serve

Patent Drawing Services

Patent drawing services draw your figures for a per-sheet fee and deliver in days. PatentStroke is the self-serve alternative to a patent drawing service: upload photos, sketches or claims, get USPTO-formatted sheets in minutes, and pay per application instead of per sheet.

When to hire a patent drawing service

A drafter is still the better choice for some applications. Here is how we would decide.

Hire a drafting service

A design patent that needs six or more exactly matching views with surface shading.
A dense mechanism where choosing views and sections is a judgement call.
A high-value or contested case where every line will be scrutinised.
You have no time to review drawings yourself.

Make them yourself in PatentStroke

A provisional application, where speed matters more than polish.
A utility application for a product you can photograph or sketch.
Method claims that need flowcharts, and systems that need block diagrams.
Drawings you expect to change as the claims change.

What drives per-sheet prices: patent drawing cost

What to ask a patent drawing service before you hire one

Six questions that make quotes comparable and avoid surprises after filing.

Is the quote per sheet or per figure, and how many revision rounds does it include?
What is the normal turnaround, and what does rush delivery cost?
Who sees my invention, where are the files stored, and when are they deleted? Will you sign an NDA?
Do I get editable source files (vector PDF, SVG or CAD), not only a flat PDF?
Are the sheets laid out to 37 CFR 1.84, and are corrected sheets after a drawing objection included?
Can I see a sample set for an invention similar to mine?

How it works

How to make patent drawings in three steps

No CAD skills and no back-and-forth with a drafter. You stay in control of every figure.

01
Upload or paste
Add a photo or a hand sketch of your invention, or paste method steps, a method claim or a system description.
02
Generate the figure
PatentStroke draws clean black-and-white line art, or lays out a numbered flowchart or block diagram. Adjust the line threshold or regenerate until it looks right.
03
Export the sheet set
Add figures to a sheet set. FIG. labels, sheet numbers and USPTO margins are applied for you; export a vector PDF, 300 DPI PNG or SVG.
