Method flowchart

Patent Flowchart Generator

Paste the steps of your method, or the method claim itself, and get a patent flowchart: one box per step, numbered S101 onward, connected by arrows and drawn in black and white to the patent sheet rules.

Input

Method claims to flowcharts, without drawing boxes

  • Numbered steps

    Each step gets a label such as S101, S102, so the description can refer to it.

  • Decisions and loops

    Conditions become decision boxes with yes/no branches; repeated steps loop back with arrows.

  • Readable on the sheet

    Text stays at least 0.32 cm tall. A long flowchart is split over sheets (FIG. 2A, 2B) with off-page connectors.

  • From plain text

    Numbered steps, a paragraph or a claim all work; you do not need to format anything.

  • Vector export

    Export a vector PDF, 300 DPI PNG or SVG. Text stays sharp at any zoom.

  • 5 credits a diagram

    Half the price of an image figure, usually ready in under a minute.

Why method claims need a flowchart

Every feature in the claims must be shown in the drawings (37 CFR 1.83(a)). For a method claim, that is usually a flowchart: each step in a box, in order, with the step numbers the description refers to.

Software, business-method and process inventions often rely on flowcharts alone, so getting them clear and consistent matters.

How to make a patent flowchart

  • Sign up and open the flowchart generator.
  • Paste your method steps or method claim.
  • Generate. Steps are numbered and laid out top to bottom with arrows.
  • Add the flowchart to a sheet set and export PDF, PNG or SVG.

Tips for clear input

  • One action per step: "receive a request", not "receive and validate a request and store it".
  • State conditions plainly: "if the temperature exceeds the threshold, …; otherwise, …".
  • Keep step text short; the description carries the detail.
