Does this replace legal review?

No. PatentFig AI accelerates drawing preparation and pre-filing checks, but attorney or agent review is still needed before submission.

How do UML, sequence, ER, and use-case diagrams become patent figures?

PatentFig AI takes a UML, sequence, ER, use-case, or system/software-architecture diagram and routes it into the patent workflow, rendering it as a software-patent figure with modules, arrows, and reference numerals that meet patent drawing rules.

How many modules should a software patent block diagram show?

Six to nine is the readable range. More than ten signals the figure is trying to be a deployment diagram instead of a patent diagram — split into companion figures.

Can vendor names appear inside boxes?

No. Replace specific vendors ("AWS Lambda", "OpenAI", "Stripe") with functional roles ("serverless compute", "language model service", "payment processor"). The claim should not depend on a specific vendor.

Do I need both a block diagram and a flowchart for a software patent?

Usually yes. System claims are supported by the block diagram (what the modules are), and method claims are supported by a flowchart (what the steps do). Filing one without the other leaves half the claim set without figure support.

UML & Software Diagram Maker

Create patent-ready figures for UML, sequence, ER, use-case, system and software-architecture diagrams, and block diagrams.

Start from a UML, sequence, ER, use-case, or system/software-architecture diagram, a technical description, or an invention disclosure.
Generate software-patent figures with modules, arrows, and reference numerals that meet patent drawing rules.
Refine labels, arrows, view layout, and figure structure through focused iterations.
Connect the result to Figure Checker, export tools, and the broader patent drawing workflow.

A practical generation flow

UML & Software Diagram Maker is organized around source preparation, figure generation, revision, and final review.

Prepare the source

Use a UML, sequence, ER, use-case, or system/software-architecture diagram, a technical description, or an invention disclosure with enough structure for PatentFig AI to infer the drawing relationships.

Generate the figure

Create software-patent figures with modules, arrows, and reference numerals that meet patent drawing rules with patent-style composition, line work, and reference structure.

Check and export

Use review and export tools once the layout, labels, and file format are stable.

Why this workflow needs a patent-specific tool

Generic image tools do not consistently handle UML, sequence, ER, use-case, system and software-architecture diagrams, and block diagrams with the structure patent drawings need.

Patent-first structure

The workflow emphasizes readable parts, relationships, and reference numerals for UML, sequence, ER, use-case, system and software-architecture diagrams, and block diagrams.

Iteration without restarting

Adjust the figure prompt, regenerate focused views, and keep the surrounding workflow stable.

Review before export

Check visual clarity, margins, line work, labels, and file readiness before downstream filing work.

Common mistakes in software patent diagrams

Pasting the product architecture slide directly into the patent application — branding and vendor names count as extraneous matter.

Naming modules with implementation labels ("Stripe webhook", "OpenAI endpoint") instead of stable functional names.

Forcing architecture, method, and UI into one diagram instead of splitting them into companion figures.

Omitting reference numerals because "the modules are obvious from the names."
