Built-in Figure Checker validates each figure before you file

Why "online" matters for USPTO patent drawings

Filing teams used to depend on either expensive illustration vendors or desktop CAD/Illustrator setups. Both fail the same way: slow turnaround at the worst moment.

Same-day turnaround
No vendor email loop. Generate, refine, and export in one session — useful when an attorney is finalizing claims hours before filing.
No software install
Browser-based generation means you can work from a laptop, a client meeting room, or a hotel without provisioning Adobe or AutoCAD seats.
Predictable cost
Per-figure illustrator fees disappear. Pricing is a flat monthly subscription so the cost of an extra revision round is zero.

How PatentFig targets 37 CFR §1.84

Each clause of §1.84 maps to a specific generator constraint and a specific Figure Checker rule.

§1.84(f) — Paper size
Default export is A4 (21.0 × 29.7 cm) or 8.5 × 11 inch with the correct margin reservation: 2.5 / 2.5 / 1.5 / 1.0 cm.
§1.84(l) — Line quality
Uniform line weight, solid black, no fragmented strokes. The most common formal rejection reason is enforced at generation time, not patched after.
§1.84(p) — Reference characters
Sans-serif numerals at least 3.2 mm (1/8 inch) tall, oriented consistently across the entire figure set with cross-figure tracking.

USPTO Patent Drawings Online FAQ

Can I generate USPTO patent drawings online?
Yes. PatentFig generates USPTO-targeting patent drawings entirely in your browser. The generator targets 37 CFR §1.84 (paper size, margins, line weight, reference numerals, shading conventions) and the built-in Figure Checker validates each output before filing.
Is there a free way to generate USPTO patent drawings?
PatentFig has a free tier you can use without a credit card. Paid plans start at $50/month (Basic), $100/month (Pro), and $1,999 lifetime — useful when you need higher figure volumes or team seats.
Will online-generated drawings pass USPTO formal review?
The generator enforces the same constraints that USPTO examiners check — uniform line weight, correct margins, sans-serif reference numerals at the right height, allowed shading conventions. Most rejections come from violating these formal rules, which the tool prevents at generation time rather than after.
Do I still need an illustrator?
For most utility patent applications and design patent applications, no. An illustrator may still be useful for complex technical disclosures (highly mechanical assemblies with detailed cross-sections), but the per-figure economics for routine filings strongly favor online generation.
Can the same drawing be used for USPTO and other offices?
Yes. PatentFig keeps a single source figure and exports compliance variants for USPTO, CNIPA, EPO, JPO, KIPO, and PCT. The Figure Checker validates each variant against its target office.
What file formats are exported?
PNG and TIFF at 300 / 600 DPI for direct USPTO submission, plus vector SVG and PDF for downstream editing. The Vectorize tool also converts existing raster drawings into editable vector formats.
