What PatentFig AI is
PatentFig AI is an AI-native platform for creating patent drawings through a web interface, with no manual drawing or CAD skills required. You describe an invention or upload a photo or sketch, and it generates labeled line drawings, 3D renderings, and flowcharts that aim to meet the requirements of major patent offices such as the USPTO, EPO, JPO, KIPO, CNIPA, and the PCT. A chat-based editor lets you refine figures in plain language, and uploaded files are encrypted in transit and at rest and are not used to train the model. There is a free trial with no credit card, free accounts get 20 credits per month, and paid plans raise the limits. It serves patent lawyers, inventors, and corporate IP teams.
What you can do with it
- Generate compliant line drawings with reference numbers and leader lines from a photo or sketch.
- Produce 3D renderings and multiple views of an invention.
- Build flowcharts and system block diagrams for method or architecture claims.
- Edit figures by typing instructions, such as making an arrow thicker.
- Export files formatted for filings in several patent offices.
Who it is for
- Patent lawyers and agents who prepare many figures per case.
- Inventors without drawing or CAD experience.
- Corporate IP departments handling global filings.
What to watch out for
Free accounts are capped at 20 credits per month, and the free trial and credit rules can change, so check current terms if you file often. Generated figures should be reviewed against the specific office's formal rules before submission, since compliance requirements vary and errors can affect a filing. Higher credit limits require a paid plan, so heavy caseloads add cost. Uploaded material is often sensitive, so confirm the current privacy and deletion policy before sharing confidential designs, and keep your own copies of final files.
