New: Vectorize Tool

Convert raster patent figures into editable vector formats using AI-powered vectorization — no more pixel-traced outlines or broken line segments.

• SVG output: Resolution-independent vector graphics, editable in Illustrator or Inkscape
• DXF output: Clean polyline geometry for CAD programs (AutoCAD, LibreCAD), ready for adding reference designators and nomenclature
• PDF output: High-quality PDF with embedded SVG attachment for downstream editing
• AI vectorization produces true geometric lines and curves, not pixel traces

New: DPI Enhance Tool

Upscale patent figures to publication-ready resolution in one click.

• 2K (300 DPI): Standard submission quality, 2048px long edge
• 4K (600 DPI): High-fidelity output, 4096px long edge
• Output formats: PNG and TIFF
• AI-powered crisp upscaling preserves line art quality

Improvements

• Split the former Convert tool into two focused, purpose-built tools
• Added /convert redirect to /enhance for existing bookmarks
• Updated navigation with dedicated entries for Vectorize and DPI Enhance
• Figure Checker now links directly to Enhance or Vectorize based on detected issues

Compliance and Output Quality

• Office Preset Refinement: Tuned formatting defaults for CNIPA, USPTO, EPO, and JPO workflows
• Drawing Normalization: Improved line consistency and figure spacing for cleaner submissions
• Reference Consistency Checks: Added validation for common numbering and label mismatches
• Export Quality Controls: Better default resolution and output stability across formats

Workflow and Management

• Enhanced project-level organization for figure sets and versions
• Improved status visibility from generation to export completion
• Added clearer grouping of assets for large multi-view submissions

Reliability and Fixes

• Increased generation retry stability under network fluctuation
• Reduced timeout-related failures for long-running tasks
• Fixed intermittent failures when exporting large figure sets
• Improved overall responsiveness on dashboard-heavy workspaces

New Features

• Chat-to-Modify: Edit generated figures with natural language instructions such as line weight, arrows, and view changes
• Sub-Version Timeline: Track V1.1, V1.2 style edits and compare or revert quickly
• Figure-Set Export: Export multiple views in one action to reduce repetitive operations
• Prompt Reuse: Re-run generation from prior prompts and references to speed up iteration

Product Enhancements

• Improved preprocessing for noisy sketches and low-contrast references
• Optimized queue scheduling to reduce peak-hour wait time
• Added clearer progress and error messages in generation states

Bug Fixes

• Fixed occasional duplicate reference labels in regenerated figures
• Resolved missing thumbnails after retrying failed jobs
• Fixed edge cases where export format selection was not persisted

Core Capabilities

PatentFig AI launched with the essential tools for patent drawing delivery:

• AI Figure Generation: Generate line art, multi-view renderings, and flowcharts from natural language descriptions
• Multi-Modal Input: Start from text prompts, reference photos, sketches, or CAD screenshots
• Project Workspace: Organize figures by application and keep all assets in one place
• Version History: Save each generation as a version for traceable iteration
• Professional Export: Export to PDF, PNG, SVG, and TIFF for filing workflows

Platform Foundation

• Built the first production pipeline for prompt parsing, generation orchestration, and asset storage
• Added account system, credit usage flow, and protected workspace access
• Established generation logs for troubleshooting and quality verification

Stability and Fixes

• Improved upload success rate for large reference images
• Reduced failures caused by malformed prompt payloads
• Fixed several UI inconsistencies in generation and export states
