23VIP vs DeepIP: AI Patent Drafting Software Compared (2026)
Last updated: 3 August 2026
Short version: 23VIP covers the core patent work end to end — claims, specifications, drawings, office action responses, prosecution analysis, and patentability opinions — built on European practice, with an EU-hosted model option and published pricing (€199/attorney/month, all tools). DeepIP is a US-rooted Microsoft Word add-in for drafting and prosecution, with adjacent analytics modules sold alongside. Both produce attorney-reviewable drafts and neither trains models on your data. Which fits you depends on your jurisdiction mix, your budget model, and where your confidentiality lines sit.

Feature Comparison
| 23VIP | DeepIP | |
|---|---|---|
| Core focus | The core patent work end to end: claims, full specifications, patent drawings, office action responses, prosecution analysis, and patentability opinions | Word add-in for drafting and prosecution; adjacent analytics modules (FTO, invalidity search) sold alongside |
| Where you work | Web applications | Microsoft Word add-in |
| European practice | Built European-first: two-part claims, problem-solution structure, Art. 123(2) discipline; also drafts for USPTO and other jurisdictions | US-rooted; European coverage strengthened by the 2026 PatentMaker acquisition (Munich) |
| Model choice & hosting | EU-hosted open-source models or frontier models (Gemini, GPT, Claude) — your choice per matter; no training on your data | Proprietary fine-tuned GenAI models; zero-retention terms; no EU-hosted open-source option advertised |
| Pricing | Published: €199/attorney/month or €1,999/year (all tools); day passes from €40, no subscription required | Not published; ~$350–420/user/month per third-party reports |

Choose DeepIP if…
- Your attorneys work in Microsoft Word and won't leave it — DeepIP's add-in is genuinely seamless.
- You want FTO and invalidity search analytics bundled inside the same product.
- You draft chemistry cases — DeepIP's Markush and stereochemistry support leads the category.
Choose 23VIP if…
- You want one subscription that covers the actual daily work: claims, specifications, drawings, office action responses, prosecution analysis, and patentability opinions.
- Your practice is European or EPO-heavy — drafting logic that starts from EPC practice, not adapted to it.
- Client or firm policy requires that unpublished disclosures stay in the EU: 23VIP's EU-hosted open-source model option is unique in this category.
- You prefer €1,999/year published — or day passes with no commitment at all — over ~$4,000–5,000 per seat per year reported and negotiated per deal.
- You want to evaluate the tool today, on a free trial, without a sales cycle.
The Honest Bottom Line
DeepIP's Word integration and chemistry tooling are real advantages, and it bundles FTO and invalidity analytics that 23VIP doesn't offer. For the work patent attorneys actually do every day — drafting claims, specifications, and drawings; responding to office actions; assessing patentability — 23VIP covers all of it, at published pricing, with European practice depth and an EU data-residency option DeepIP can't match. If you regularly answer to the EPO — or to clients who ask where their disclosure data physically sits — start with 23VIP's trial and compare the output on one of your own cases.
