I create professional patent drawings, patent figures, and technical illustrations for inventors, startups, engineers, product developers, manufacturers, and IP professionals. I transform sketches, photos, CAD models, prototypes, and existing drawings into clear, precise, well structured figures, including utility and design patent views, sectional, cross sectional, exploded, and detail views. My focus is technical accuracy, clean line work, clear reference numerals, and dependable communication from concept to final files.
FAQ
What exact files do I need to send you to get started?
Send over rough hand sketches, reference photographs, existing CAD files, 3D models (STEP/IGES), or written functional descriptions. Even napkin sketches or marked up product photos are fully sufficient to begin drafting.
Are your patent figures 100% compliant with USPTO and international rules?
Yes. Every line, margin, leader line, and reference numeral is meticulously formatted to meet strict USPTO (United States Patent and Trademark Office) and WIPO/PCT standards, eliminating the risk of formal office action rejections.
How do you handle reference numerals and part callouts?
You can provide an itemized list of your parts and corresponding numbers, or I can systematically review your functional description and cleanly map out the reference numerals across all requested views.
What file formats will I receive upon project completion?
You receive print ready, high resolution vector PDF and TIFF files for official filing, alongside fully editable vector source files (AI/SVG/DWG) for any future modifications by you or your patent attorney.
Can you handle complex mechanical assemblies requiring exploded and sectional views?
Yes. The Standard and Premium packages are custom built for multi part mechanical devices, consumer products, and hardware innovations requiring complex internal sectional slices and exploded assembly views.
What is your turnaround time for urgent patent filing deadlines?
Standard delivery ranges from 2 to 5 days depending on the complexity and tier selected. Expedited delivery workflows are available for inventors facing tight provisional or utility filing cutoffs.
Can you convert my existing rough patent drawings into formal office ready vector figures?
Yes. If you have older hand drawn figures, blurry scans, or unformatted diagrams, I can completely redraw, clean up, and format them into crisp, professional vector patent illustrations.
Do you sign Non Disclosure Agreements (NDAs) to protect my invention?
Absolutely. Your intellectual property, invention concepts, and proprietary design files remain 100% confidential and secure at all times. I am fully open to signing your NDA before starting work.
What is the difference between Utility and Design patent drawing requirements?
Utility patent drawings focus on functional parts, structural mechanisms, and internal flows using multiple views and reference numbers. Design patent drawings focus purely on the ornamental appearance and surface contouring via precise orthographic projections.
How do revisions work if my patent attorney requests modifications?
Every package includes dedicated revision rounds. If your patent attorney or agent requests specific layout adjustments, line weight tweaks, or numbering updates, I will fine tune the figures until they are fully publication ready.
