Claim Drafter thinks like a European patent attorney, guiding you step by step from claim 1 through a full claim tree. Generate and edit drawings, place reference numbers by hand or with AI-assisted review, convert claims between jurisdictions, and pick up saved projects where you left off. Works in any language.

Web Drafter is a patent drafting workspace: generate a complete application in one pass or build it section by section, then edit the result in your browser with AI chat before you download. Handles inventions of any complexity, in any language.
Learn MoreReply Drafter
Reply Drafter analyzes office actions against the cited prior art and drafts complete, filing-ready replies, phase by phase with your review at each step. Imports your file automatically from the EPO and USPTO registers, checks a client's own draft reply, and works from your saved templates and drafting-style profiles. Runs exclusively on frontier models (Gemini, Claude Opus, GPT).

23VIP gives you the choice between EU-hosted open-source AI, such as Mistral, and frontier models used under business terms that prohibit training on your data. On the EU-hosted path, client data is processed ephemerally within European infrastructure and is not retained. This architecture is intended to support confidentiality-sensitive patent work.
- Industry-standard encryption for all data in transit and at rest
- You choose the processing path per tool: EU-hosted open-source models or frontier models, both configured not to train on your data
- Across all drafting tools, 23VIP is designed to prevent internal access to your patent data inputs and outputs
