23VIP vs. ChatGPT & General LLMs for Patent Drafting
AI patent drafting requires specialized tools and clear model governance. While ChatGPT, Claude, and other general-purpose large language models can generate text, they are not a substitute for a tool specifically designed for European Patent Attorneys.
This comparison explains why patent attorneys choose 23VIP over general LLMs for drafting claims, specifications, and patent applications.
Feature Comparison
| Feature | General LLMs (ChatGPT, Claude, etc.) | 23VIP Patent AI |
|---|---|---|
| Data Privacy | May train on your inputs; policies vary and change | Open-source European-hosted mode by default; no training on your data in that default path |
| Confidentiality | Shared infrastructure; unclear privilege status | Isolated processing; designed for privileged work |
| Claim Logic | Generic text generation | Writes and thinks like a European Patent Attorney |
| Terminology | Conversational English | Patent-specific phrasing ("patentese") |
| Hallucination Risk | High—may invent prior art or citations | Constrained to user-provided disclosures + warning for prophetic examples |
| Output Format | Requires extensive prompting for structure | Native patent application format |
| Legal Compliance | No EPO-specific checks | Built for European patent practice |
| Support | Generic help documentation | Support from European Patent Attorneys |
What are the main risks of using AI for patents?
When you input an invention disclosure into a general LLM:
- Confidentiality: Not always guaranteed for general LLMs; guaranteed under the LLM APIs we use
- Training on data: Your technical details may be used to train future model versions, potentially exposing novel concepts
- Hallucinations: General LLMs may invent prior art, citations, or technical details that don't exist
- Policy Changes: LLM providers frequently update terms of service—today's opt-out may not exist tomorrow
23VIP's commitment: our default mode uses open-source models hosted in Europe, selected because they do not train on your data. Commercial models remain available only on demand and can be disabled by account policy.
Patent-Specific Logic
General LLMs have been trained on a large variety of materials and do not fully understand the constraints of patent drafting.
23VIP thinks like a European patent attorney. It understands EPO claim drafting conventions, problem-solution approach for inventive step analysis, and proper claim structure for European practice. Just as importantly, 23VIP makes the confidential European mode the normal user journey instead of leaving confidentiality to provider settings alone.
When to Use Each Tool
Use 23VIP when:
- Drafting patent claims or applications (in any language)
- Working with confidential invention disclosures
- Preparing EPO, PCT, or national filings
- You need output ready for attorney review
General LLMs may be acceptable if you have selected a plan that guarantees confidentiality
In that case, general LLMs can be excellent for brainstorming and can help with the revision of specific sections of the patent draft.
