Feature
New: Matter management for law firm patent drawing workflows
PatentDrawingAI now helps law firms organize patent drawing projects by client matter, import matter lists from CSV, and export matter-based drawing usage for billing or internal review.
Added
Matter management for patent drawing projects, including client name, matter name, docket or matter number, responsible attorney, and drawing type.
CSV matter import with column mapping, duplicate preview, invalid-row review, and support for client-only, matter-only, or docket-only matter records.
Matter-based usage export so law firms can download patent drawing activity by date range, client, matter, project, drawing type, and credits used.
Changed
Project creation can now link a new drawing project to an existing matter, create a new matter, or leave the project unlinked when matter attribution is optional.
Project workspaces now show matter context so users can see which client matter future drawing activity will use.
Fixed
Usage reports keep historical matter attribution from the time credits were spent, so later matter changes do not rewrite past billing records.
CSV usage exports now use safer formatting for spreadsheet tools and clearer user-facing import messages.

Seven practical ways to reduce patent drawing spend, including the hybrid AI-plus-professional workflow that cuts total cost by 70–80% on most filings.
Feature
A complete filing-ready patent drawing workflow
PatentDrawingAI now goes beyond patent drawing creation: add reference numbers, leader lines, vector annotations, and assemble USPTO-formatted drawing sheets with compliant margins, sheet numbers, FIG. labels, and layouts for up to four drawings per page.
Added
Structured vector annotations for patent drawings, including reference numbers, leader lines, text labels, section labels, shapes, hatching, and whiteout regions.
Assembly-page label correction so reference numbers, text labels, and section endpoint labels can be moved directly on the final drawing sheet.
Live label drag feedback in Drawing Set assembly so filing labels move visually with the pointer before the server-rendered preview refreshes.
Changed
Drawing Set assembly now better supports the full patent drawing workflow, from drawing creation through USPTO-formatted sheet layout and export.
Multi-figure sheet presets preserve filing-readable annotation sizes across 1-up, 2-up, 3-up, and 4-up layouts without changing the original drawing anchors.
Preview and export rendering are more tightly aligned for filing-ready PDF, SVG, and PNG drawing set outputs.
Fixed
Moving labels on the Assembly page no longer changes the underlying source drawing geometry or reference anchor points.
Landscape figure label dragging now converts movement correctly.
Export validation messages now use clearer user-facing language.

Feature
Welcome demo's Drawing Set now leads with the same figure as the project page
Open Drawing Set on your Welcome demo project and FIG. 1 is now the same figure that sits on the left of your project page. The two surfaces line up.
Changed
Welcome demo project's Drawing Set now opens with the same lead figure as the project page on new accounts.
Feature
Demo project: deleting your card no longer affects other users
Removing a drawing from your Welcome demo project now cleans up your view in isolation, leaving every other user's demo intact.
Fixed
Deleting a drawing from the Welcome demo project no longer affects what other users see in their own demo.
Feature
Assemble all your figures into one filing-ready drawing set
Open Drawing Set on any project to lay your figures out across sheets, pick layouts (1-up, 2-up, 4-up), set sheet numbering and identifying indicia, then export a USPTO-formatted multi-page PDF in a click.
Added
Drawing Set page on every project: lay figures out across sheets, drag to reorder, pick a layout per sheet, export a filing-ready PDF.
Five layout presets per sheet — 1-up full, 2-up stacked, 2-up side-by-side, 3-up (1+2), and 4-up quadrant.
Per-figure orientation toggle (portrait or landscape) — landscape figures rotate together with their FIG. label inside the slot.
Per-sheet controls for paper size (A4 or US Letter), sheet number position (top-center or top-right), and optional § 1.84(c) identifying indicia in the top margin.
Lock the figure number for any drawing so it stays pinned to a specific FIG. number even when other figures move around.
Multi-page PDF export at 300 DPI with correct USPTO sight margins on every sheet.
Feature
Sharper patent drawings — cleaner system diagrams, better product cleanup
System diagrams now keep their component labels, product drawings handle dark surfaces and embossed brand marks more reliably, and each drawing type is tuned independently.
Changed
Product and system-diagram drawings now use separate optimization paths instead of one shared prompt — each tuned for its source category.
System-diagram outputs now preserve the component labels from your source (no more boxes-with-no-text figures).
Fixed
Recessed features and openings on product drawings no longer collapse into solid filled regions — interiors stay white with only the rim outlined.
Dark or non-white source surfaces now render with clean white interiors and outline edges, regardless of how dark or richly colored the source appears.
Brand marks that are molded or embossed into the surface of a product are now removed, not traced as geometry.
Edits on system diagrams that involve relocating or removing text now work correctly.
Feature
More room to type in the annotation sidebar
Leader-line style and arrow-tip options now live together in a single compact button, freeing up space to type longer component names.
Changed
Leader-line style and arrow-tip controls are now combined into a single decorate button per reference-label row, giving the label description input more room to breathe.
Feature
Annotations you add in the editor stay put when you navigate away and back
Place a reference label, step out to the project page, come back — your label is there, no hard refresh needed.
Fixed
Navigating away from the editor and back no longer shows pre-save state for saved annotations or layout changes.
Very fast navigation immediately after an edit now reliably persists the latest change instead of dropping it.
Feature
New S-curve leader line style for annotations
Pick from three leader styles — straight, curved, or S-curve — right from the annotation list, with a visual picker that shows each shape at a glance.
Added
S-curve leader line option for annotation labels, great for routing around dense drawings.
Changed
The leader-style button now opens a small picker with mini previews of all three styles side by side, making the choice easier to see before you click.
Feature
Faster drawing editor — quicker loads and instant version switching
Opening a drawing from your project page now paints faster, and switching between version thumbnails inside the editor happens without the small pause you used to see after every click.
Changed
Faster cold load when you open a drawing from the project page.
Instant switching between version thumbnails inside the drawing editor.
Feature
New accounts get a Welcome Project with demo drawings
Every new account now starts with a Welcome Project containing example utility and design patent drawings so you can try the editor, versioning, auto-labeling, and downloads without spending credits.
Added
Welcome Project with four example drawings across utility and design task types, available on every new account.
Dashboard welcome banner that explains the demo and links straight into the project.
Feature
Design patent drawings now preserve input geometry
Design runs occasionally altered the subject — for example, closing an open corkscrew worm from the line-art reference. Lowered the design-task generation temperature so the model sticks to the input geometry.
Fixed
Occasional subject drift on design patent drawing runs (for example, closing an open corkscrew worm from the line-art reference).
Changed
Design generation now uses the same low-temperature configuration as edits so it preserves the input geometry.
Feature
Clearer Edit tab guidance in the drawing editor
The Edit tab's instruction now shows the Region Edit tool icon inline, matching the pattern already used in the Labels tab, and drops a redundant guidance line in the empty state.
Changed
Edit tab instruction embeds the Region Edit tool icon inline, matching the Labels tab pattern.
Edit tab empty state no longer repeats the top instruction in different words.
Feature
Restored crisp line quality on generated drawings
Drawings were coming back with ghosted, multi-stroke edges and spurious borders. Restored the original working Gemini configuration so outputs are crisp single-stroke line art again.
Fixed
Ghost-stroke / smeared output and spurious borders on generated utility and design patent drawings.
Changed
Input images are sent to Gemini as inline base64 instead of via the Files API, matching the original working pipeline.
Generation output resolution restored to 1K to match the original pipeline; 2K was producing sketchy output on the preview models.
Per-task-type generation parameters restored to proven values (new drawings at 0.25/0.85, edits at 0.1/0.8).
Feature
Curved leader lines for reference labels
Reference labels can now use a smooth curved leader line in addition to the existing 90-degree elbow style, toggleable per label from the annotation sidebar.
Added
Curved leading lines — optional arc style per reference label, toggleable from the annotation sidebar.
Curve-aware arrowhead orientation so arrow tips follow the tangent of the curve at the anchor.
Feature
Artboard editor overhaul, annotated exports, and download parity
The editor now uses an artboard-based document model, annotated exports are more consistent, and project-page downloads match the export controls available in the editor.
Added
An artboard-based editor document model that keeps layout, transforms, labels, and export geometry in one place.
Drawing layout controls for scale and rotation directly inside the editor experience.
Annotated export options on the project page, including PNG, SVG, and PDF downloads that match the editor flow.
Changed
Annotated export leader lines now render closer to the on-screen artboard appearance.
Export modal copy and icon sizing were cleaned up so format choices read more consistently.
Completed drawings now show a loading spinner while preview assets resolve, instead of an incorrect refresh warning.
Fixed
Autosave no longer flushes stale editor state while a region-edit request is frozen in flight.
Label sidebar affordances now use the updated arrow icon and faster tooltip behavior.
Version download flows on the project page now expose the same annotated and non-annotated choices as the editor.
