The 30-second answer
- For full application drafting inside Microsoft Word with published security certifications, DeepIP and Solve Intelligence are the most widely adopted (400+ and 700+ IP teams respectively; both enterprise-priced, no public pricing).
- For a self-service price you can see today: qatent (€200/user/month), Patent Bots Prep & Pros Pro ($702/person/year), Patsnap Eureka ($100/month); PatentPal offers a free trial.
- PatentFig AI is not a drafting tool. It generates and checks the figures ($50/month, six offices) and slots next to any of the tools above.
How we compared
All ten tools were checked on 8 September 2026. Features and prices were read from each vendor’s official site on that date; items marked "Not published" were not disclosed by the vendor, and we did not fill gaps from third-party listings. Specifio (site offline) was excluded, and "Davinci" is DeepIP’s former name. Reviewed by Davie, founder of PatentFig AI. The eight criteria:
1
1. Claims and specification drafting
Whether the tool drafts a complete application, only parts of the specification, or none.
2
2. Office actions
Response drafting, argument and amendment support, or response shells and forms.
3
3. Prior-art search
Patentability, invalidity, FTO, and monitoring, or examiner analytics only.
4
4. Figures
Which figure types the tool generates (line art from sketches or photos, flowcharts, block diagrams) and which office rules it names; several suites now produce USPTO and EPO line art.
5
5. Integration
Word add-in, web app, desktop app, document management, or API, as listed by the vendor.
6
6. Security
Certifications, training statement, retention, and data residency, exactly as published.
7
7. Pricing transparency
Whether a self-service price is published, and the entry price on the date checked. Seven of the ten publish no price.
8
8. Fit for attorneys
Whether the tool fits an attorney’s existing drafting workflow, and where a separate figure tool is still required.
Not for
Three honest limits that a feature list does not show.
DeepIP, Solve Intelligence, Rowan, and Edge are not for buyers who need a price today
None of the four publishes pricing; each starts with a demo or a trial request. If you need a price before a call, qatent (€200/user/month), Patent Bots ($702/person/year), and Patsnap Eureka ($100/month) publish theirs.
Drafting suites are not for CNIPA, JPO, KIPO, or PCT figure checks
DeepIP and Solve Intelligence name USPTO and EPO rules for their figures. None of the ten publishes a check for CNIPA, JPO, KIPO, or PCT figure rules; PatentFig AI’s figure checker covers all six.
PatentFig AI is not for claims or specifications
PatentFig AI generates, edits, checks, and exports figures only. Draft the text in any of the tools above, then generate figures from the claims, a sketch, a photo, or a 3D model, and export PNG, SVG, DXF, or vector PDF.
Free and low-cost options
No full drafting suite is free, but three pieces of the workflow are.
Google Patents (free)
Prior-art search across 120M+ publications from 100+ offices, at no cost.
PQAI ($0, or $20/month)
AI prior-art search with a free plan; PQAI+ is $20/month or $216/year.
Inkscape (free)
Open-source vector editor for touching up figures by hand; exports SVG, PDF, EPS, PNG, and DXF, with no patent-rule checks.
PatentFig AI free tier
Generate and check a first set of figures on 20 free credits before choosing a plan.
How the tools fit together
A typical AI-assisted patent workflow uses more than one tool.
Search prior art
Use Google Patents, PQAI, IPRally, or the search module of your drafting suite to assess novelty before drafting.
Draft the specification
Draft claims and the written description in DeepIP, Solve Intelligence, Rowan, Edge, XLSCOUT, or qatent.
Generate the figures
Use the suite’s own figure tool for USPTO or EPO line art, or PatentFig AI when you need six-office checks, photo or 3D inputs, or DXF and vector PDF export.
Check and file
Validate figures against your office, then assemble and file after a qualified attorney or agent reviews text and figures.
