Changelog

New: Tools Workspace

Image preparation tools now live in one unified workspace. Instead of opening each utility from separate entry points, you can go to Image Tools and choose the exact action you need.

• Convert Image — export one image to PNG, TIFF, PDF, or SVG
• DPI Enhance — improve low-resolution figures before export
• Vectorize — turn raster drawings into editable SVG, DXF, or PDF
• Figure Checker — review format, DPI, color, transparency, and background
• Trademark Drawing — create office-ready trademark drawing files

The Tools workspace uses larger visual cards, animated tool icons, and direct entry into each workflow.

New: Multi-Image Custom Input

Custom mode now supports up to three reference images in one request. You can combine a product photo, logo, sketch, screenshot, or style reference, then describe the finished image you want.

• Use a product photo to define the object
• Use a logo image to preserve mark shape and proportions
• Use a sketch or style reference to guide layout, material, or scene
• Generate packaging concepts, product visuals, logo placement previews, UI edits, or richer reference-based outputs

We also added a workflow page with real example case images showing input references and final product-style outputs.

Improvements

• The top navigation now sends Image Tools directly to the unified Tools workspace
• Custom mode accepts multiple uploads when the active workspace is Custom
• Multi-image Custom content is available across supported site languages

New: Lifetime Membership

A one-time payment unlocks the highest plan permanently — no renewals, no annual increases.

• $1,999 one-time — pay once, use forever
• 5,000 credits per month, for life — higher than the Enterprise yearly plan
• Includes everything in Enterprise
• Highest priority generation queue
• Early access to new models and features
• Free lifetime updates
• Lock in today's pricing forever

New: SVG Generation

Generate patent figures directly as scalable vector graphics — perfect for USPTO submissions and infinite zoom.

• Native SVG output — clean, editable vector paths instead of rasterized images
• Resolution-independent — scale to any size without quality loss for filings, presentations, or print
• Smaller file sizes — vector format keeps drawings lightweight even at large dimensions
• Edit-friendly — open in Illustrator, Figma, or Inkscape to fine-tune lines, labels, and reference numbers
• Reference links to generated SVGs are now persisted in chat history for easy retrieval

Improvements

• Pricing page now shows a third Lifetime toggle alongside Monthly / Yearly
• Selecting Lifetime presents a focused two-card view (Free + Lifetime)
• New Get Lifetime Access CTA on the lifetime plan card

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
