Utility Patent Drawings
Sectional views, exploded assemblies, flowcharts and block diagrams — fully numbered and compliant with 37 CFR §1.84.
Endless Collaborations · Limitless Innovations
DuoNexus IP turns rough sketches, photographs, CAD files and 3D models into examiner-ready utility and design drawings — precise, compliant, and delivered on your deadline.
What We Draft
From a napkin sketch to a complete drawing set — we cover the full spectrum of patent illustration.
Sectional views, exploded assemblies, flowcharts and block diagrams — fully numbered and compliant with 37 CFR §1.84.
All seven standard views with flawless surface shading and broken-line conventions that protect exactly what you claim.
We work directly from STEP, IGES, SolidWorks and mesh files — extracting perfect orthographic and perspective views.
One drawing set, every jurisdiction — margins, numbering and line weights tuned for WIPO, EPO, JPO, CNIPA and IPO.
Received a drawing objection? We fix rejected figures fast — most corrections turned around within 24 hours.
Product renders, exploded views and manufacturing-ready 3D assets — for patents, prototyping, e-commerce and investor decks.
Why DuoNexus IP
Every project is covered by a signed NDA before a single file is opened. Your invention stays yours.
Standard sets in 2–4 business days. Rush filings handled in as little as 24 hours — without cutting corners.
Draftsman → senior illustrator → compliance reviewer. Nothing ships until it passes all three desks.
We revise until you and your examiner are satisfied — at no additional cost, ever.
How It Works
A sketch, a photo, a CAD file, a 3D scan, even a video walk-around. Email it or use the form below — an NDA is issued immediately.
We reply the same business day with a fixed quote and a recommended figure list — which views, sections and details your filing needs.
A specialist in your industry drafts every figure to the target office's conventions — line weights, shading, numbering and margins.
Request any change — we revise without limit until every figure is exactly right.
Final files arrive as PDF, TIFF, JPEG, DWG, AI, Visio, PPT, Word (DOC) or any format your docketing system needs — named, numbered and ready to file.
Global Reach
Wherever you file, your drawings arrive already compliant — we draft to the formal rules of 20+ jurisdictions, from the USPTO to the smallest national office.
Selected Plates
A sample of the industries we draft for, redrawn here as living figures. Full portfolios are shared privately on request — most of our work is protected by client NDAs.
Client Notes
"Zero drawing objections across forty-plus filings. DuoNexus IP catches compliance issues our previous vendor never even flagged.
"They took a shaky phone video of my prototype and returned a seven-sheet design patent set in three days. The examiner allowed it first pass.
"Our docketing team treats DuoNexus IP like an internal department. Same-day quotes, watermarked proofs, files named exactly to our convention.
"A 24-hour office action deadline, twelve corrected figures, delivered with nine hours to spare. That is why we don't use anyone else.
Questions
Anything that shows the invention: hand sketches, photographs, CAD files (STEP, IGES, SLDPRT, DWG), 3D scans, existing figures, or even a short video. We reconstruct complete, compliant views from whatever you have.
Every invention is different, so we quote per project — based on the number of figures, complexity and turnaround. Send your materials through the form below and you'll have a fixed, no-obligation quote the same business day. No surprises after the quote, ever.
Yes. We sign an NDA before reviewing any disclosure, files are stored on encrypted systems with access limited to your assigned team, and everything is permanently deleted on request after delivery.
USPTO, WIPO/PCT, EPO, UKIPO, JPO, CNIPA, IP Australia, CIPO and the Indian Patent Office, among others. Each set is prepared to the specific formal requirements of your target office.
We correct it free of charge, at priority speed — for the life of your application. Drawing objections on our work are rare, and when they happen they are our responsibility, not yours.
PDF and TIFF for filing, plus editable sources — AI, DWG, CDR, Visio, PowerPoint (PPT) and Word (DOC) — so future amendments never start from zero. Files are named and numbered to your docketing convention.
About Us
"Endless Collaborations, Limitless Innovations."
DuoNexus IP was founded on a simple observation: great patent drawings are born where two worlds meet — the engineering precision of a draftsman and the legal fluency of an IP professional. Most vendors offer one or the other. We built a studio where both sit at the same desk.
That is the "duo" in our name — and the "nexus" is you. Every project pairs a domain-specialist illustrator with a compliance reviewer who reads your figures the way an examiner will, so what leaves our desk is not just a beautiful drawing but a defensible one.
We work as an extension of your team — attorneys, agents, in-house counsel and independent inventors across 20+ countries — collaborating without limits until your invention is protected exactly as you imagined it.
