Patentfig AI

PatentFig AI is a specialized patent-drawing platform, not a general image generator. Users can describe an invention or upload a sketch, product photo, 3D model, or CAD screenshot, select views, and generate line art, renderings, flowcharts, or block diagrams. The service provides chat-to-modify editing, reference numerals and leader lines, version history, project-based figure sets, batch export, and formatting workflows for USPTO, CNIPA, EPO, JPO, KIPO, and PCT-oriented filings. The generated output remains a draft that must be checked by a patent professional and against the relevant office's rules.

✨ Key Features

• Text and image-to-figure generation — Start from an invention description, sketch, photo, 3D model, or CAD screenshot.
• Patent line art — Generate black-and-white line drawings with reference numerals and leader lines.
• 3D and multi-view rendering — Create consistent front, rear, top, perspective, and other requested views.
• Flowcharts and block diagrams — Produce system and process diagrams from described logic.
• Chat-to-Modify — Request changes such as thicker arrows or a cross-section view in natural language.
• Version control — Keep generations and sub-versions, compare changes, and revert to an earlier figure.
• Project management — Organize figure sets by patent application and track versions and compliance status.
• Office-oriented formatting — Switch workflows for USPTO, CNIPA, EPO, JPO, KIPO, and PCT/WIPO-oriented outputs.
• Professional export — Filing-sheet export for six patent offices with a compliance report requires any paid plan or credit pack. Individual figure outputs include supported PDF, PNG, SVG and TIFF formats.
• Editable reference layers — Move or renumber labels and leaders on a separate layer with any paid plan or credit pack; each edit becomes a version.
• Credit-based generation — Use monthly credits for generation and iteration; the site estimates roughly one figure per ten credits.
• Confidentiality controls — The vendor states that prompts, uploads, and generated figures are not used to train models, content is encrypted in transit and at rest, and projects can be deleted.

💳 Pricing

• Free — $0; 20 credits on signup day, then 10 free credits every day (roughly one figure/day). Daily credits expire the same day; includes anchor/multi-view, line art, rendering, flowcharts, slot regeneration and versions.
• Basic — $20/month on the displayed monthly offer; 500 credits/month (about 50 figures), multi-project workflow, slot regeneration, and version timeline review.
• Pro — $40/month on the displayed monthly offer; 1,500 credits/month (about 150 figures), higher multi-case throughput, larger figure-set review, and more iteration capacity.
• Enterprise — $80/month on the displayed monthly offer; 4,000 credits/month (about 400 figures), team-scale generation, multiple pipelines, portfolio consistency, and organization-wide workflow.

The pricing page also displays annual and lifetime billing modes and crossed-out comparison prices; confirm the active checkout amount, credit consumption, export limits, and commercial terms; filing-sheet export, compliance reports and editable reference layers require a paid plan or credit pack before purchase. Credits and generated figures are estimates, not a guarantee of legal compliance or filing acceptance.

⚖️ Alternatives Compared

🎯 Use Cases

• Inventor disclosure preparation: Turn an early sketch or product photo into a reviewable figure draft.
• Design patent views: Generate consistent multi-angle views for design-patent discussion and iteration.
• Utility patent figures: Create system diagrams, flowcharts, and labeled line art from an invention description.
• Patent-firm throughput: Keep projects, versions, and figure sets organized across active applications.
• Cross-office preparation: Adapt a source figure set for different office-oriented formatting workflows.
• Client review: Produce a clearer visual draft for inventors and counsel to annotate before formal drafting.
• Revision cycles: Use chat-based edits and version comparison to respond to review comments.
• Export handoff: Deliver PDF, PNG, SVG, or TIFF assets to an attorney or formal drafting workflow.

Patent figures can disclose unfiled inventions and confidential technical details. Review the vendor's trust terms, retention controls, model-provider arrangements, and the applicable patent office requirements. Do not treat generated figures as legal advice or file them without professional review.
