What is patent diagram software?

Patent diagram software generates and checks the schematic figures used in patent applications — block diagrams, flowcharts, system and UML diagrams — with numbered elements and the line conventions patent offices expect. PatentFig AI does this from a text description and checks the result before filing.

What kinds of patent diagrams can I generate?

Block diagrams, method and process flowcharts, software and system architecture diagrams, UML-style structure and sequence views, electrical and circuit diagrams, and AI/ML pipeline diagrams. Each has a dedicated generator linked from this hub.

Are the diagrams patent-office compliant?

PatentFig AI produces clean line-art diagrams with numbered modules and consistent references, and includes a figure checker for USPTO, EPO, CNIPA, JPO, KIPO, and PCT drawing rules so you can fix issues before filing.

Do I need a separate tool for each diagram type?

No. This hub links to a purpose-built generator for each diagram type, but they all share one workspace, one numbering scheme, and one export pipeline, so a figure set stays consistent.

How it works

From a description to a filing-ready patent diagram in three steps.

Describe the system

Paste an architecture outline, README, claim summary, or method steps — or upload a sketch.

Generate the diagram

Get a clean patent diagram with numbered modules, connectors, boundaries, and information flow.

Check and export

Run the figure checker against your patent office, then export filing-ready files.

Every patent diagram type

Purpose-built generators for each kind of patent diagram — all sharing one consistent numbering and export workflow.

Block diagrams

System block diagrams for software, hardware, AI, and platform patents.

Flowcharts

Method and process flowcharts that map claim steps to numbered nodes.

System & software diagrams

Architecture and system diagrams, including UML-style structure and sequence views.
