Patent Drawing & 3D Product Design Services
Patent Drawing & 3D Product Design Services
Patent drawings and 3D product design, from concept to filing-ready figures
Utility, design, PCT, and Hague drawings, plus CAD models and product visualization
IIPRD provides patent drawing, illustration, and 3D product design services for law firms, patent attorneys, corporate IP teams, inventors, startups, universities, and technology companies. We convert technical concepts, engineering drawings, sketches, photographs, and product ideas into clear, professionally structured visual representations, coordinated with the specification, claims, embodiments, and reference numerals.
Drawings that represent the invention clearly
Patent drawings illustrate an invention's structure, configuration, operation, components, or visual appearance, coordinated with the specification and reference numerals.
For design patents, a consistent set of views represents the claimed appearance from every angle. For utility patents, figures capture structure, function, and process.
We maintain consistency across every view so the claimed design or invention reads clearly, with broken-line representations, surface shading, and sectional views used where appropriate.
Drawings for every kind of application
Utility and design patents, PCT international filings, and Hague international designs, each to its own requirements.
Utility patents
Technical figures for structure, function, and process across all technology domains.
Design patents
Consistent views representing the ornamental appearance of a product.
PCT drawings
International application figures prepared and reviewed for numbering, clarity, and format.
Hague designs
Representations for international industrial design applications.
What we draw
Figures matched to the technology, from block diagrams to semiconductor cross-sections.
System & architecture
Block diagrams, functional architecture, component relationships, and system configurations.
Mechanical drawings
Assemblies, component and exploded views, cross-sections, and structural details.
Electrical & electronics
Circuit diagrams, schematics, block diagrams, and signal-flow diagrams.
Software & flowcharts
Flowcharts, process and data-flow diagrams, sequence diagrams, and modules.
Semiconductor drawings

From sketch, CAD, or photo to a professional figure
We convert drawings that are not yet suitable for patent documentation into clean, consistent, filing-ready figures.
From concept to prototype-ready 3D model
We turn concepts, sketches, photographs, and specifications into detailed 3D CAD models, and one model can feed both product development and patent visualization.
3D CAD modeling
Detailed models from concepts, sketches, photographs, and specifications.
Conceptual product design
Turning early ideas into structured, workable product concepts.
Assembly & exploded views
Assemblies, component placement, moving parts, and exploded 3D views.
Product enclosure design
Enclosures, mechanical interfaces, and manufacturing considerations.
Prototype-ready CAD
Models and assemblies suitable for prototype development.
Visualization & rendering
Photorealistic renders, exploded and internal-component visualization, and presentation images.
Digital tools, professional review
Digital and AI-enabled tools speed the workflow, and every final drawing is reviewed by our patent illustration professionals for accuracy and consistency.
Digital & AI-assisted workflow
Technology-assisted processes support parts of the workflow:
Professional quality review
Every drawing is checked before delivery for:
Digital tools speed the workflow. Professional review keeps every figure accurate and consistent.
Patent drawing workflow
Eight steps from source material to final, formatted drawings and 3D design files.
Source material review
