USPTO-ready drawing examples
Fictional inventions in filing style. Open one to pre-fill the generator and adapt it.
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 AI 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.
Online generation vs traditional illustration
A practical comparison for IP teams choosing between vendor-led illustration and online generation.
