PatentDrawing is an AI drawing tool for patent and invention scenarios, focused on converting invention descriptions, product photos, hand-drawn sketches, and CAD screenshots into patent-style image drafts. Its core purpose is to help inventors, product teams, and patent-related professionals quickly obtain visual drafts for internal discussions, concept explanations, or communication with professional illustrators, rather than directly producing formal application documents that can be submitted.
Main capabilities
- Patent line drawing generation: Based on an invention description or visual reference, generate clean black-and-white line drawing drafts, and you can specify view names and the details that need to be retained.
- 3D perspective and multiple views: Display product forms with 3D-style perspective views, and you can request front, rear, side, top, or exploded views. Note that the output is a flat PNG image, not a rotatable 3D model, nor an editable CAD file.
- Flowcharts and block diagrams: Describe system components, process stages, and their connections to generate flowchart or functional block diagram drafts, and you can specify labels, flow direction, and functional blocks.
- Photo to patent drawing: Convert product photos into clear patent line drawings.
- Sketch to patent drawing: Transform hand-drawn concept sketches into cleaner technical line drawings.
- Exploded views: Show how the various parts of a product are assembled together.
How to use Using the basic process: first describe the invention or upload a product photo, hand-drawn sketch, or CAD screenshot; then choose a drawing direction, such as patent-style line art, 3D-style perspective or view set, flowchart, or block diagram; finally, check the geometry, labels, arrows, and structural relationships against the original materials, and download the PNG image. The official website states that every generated image should be downloaded in PNG format and manually reviewed before use.
Applicable scenarios
- Early-stage visualization of invention concepts, as a visual starting point for discussion.
- Explain product forms from different angles such as perspective views, front views, and top views.
- Use exploded views to explain assembly relationships and component connections.
- Use flowcharts or block diagrams to organize system components and process steps.
- Develop clearer technical illustrations based on photos, sketches, or CAD screenshots.
- Prepare for communication with professional illustrators, but geometry, numbering, and application layout still need separate review.
Limitations and precautions
- The generated results are flat PNG images, not true 3D models or editable CAD files.
- AI cannot guarantee that labels and reference numbers are absolutely correct, and manual verification is required.
- The generated patent drawings are not necessarily finished products that can be submitted directly; you must confirm for yourself whether they meet application requirements.
- The official website mentions that figure numbers and reference numerals can be requested, but this needs to be provided in the prompt.The text clearly specifies the mapping relationships and checks the numbering in the image.
- The official website provides pricing plans and credit explanations (including tiered credits, number of generations, number of concurrent tasks, history retention period, watermark-free downloads, and commercial use licenses, etc.). The specific prices and terms should be based on the current information on the official website.
The official website also lists several generation examples, including a smartwatch line drawing, a smart speaker perspective view and exploded view, a water filtration system block diagram, a cordless drill view, a filtered water bottle perspective and exploded assembly, a product photo converted to line drawing, a desk lamp sketch converted to line drawing, a CAD pipe clamp screenshot, and a medical device concept diagram, etc. The page also includes fictional usage scenario examples presented with stock portraits, and states that these individuals are not verified customers or endorsers.
