What is the main difference between 23VIP and ChatGPT for patent drafting?

23VIP is purpose-built for patent work and thinks like a European patent attorney. It uses LLM APIs under business terms that prohibit training on your data, and includes built-in patent logic (antecedent basis checking, claim dependency validation). ChatGPT is a general-purpose LLM that may train on your inputs and lacks patent-specific features.

Is ChatGPT safe to use for confidential patent applications?

General-purpose LLMs like ChatGPT may use your inputs for model training unless you opt out. This creates potential risks for confidential invention disclosures. 23VIP uses LLM APIs under business terms that prohibit training, and in Claim Drafter we have zero access to your inputs or outputs.

Does ChatGPT check for antecedent basis in patent claims?

No. ChatGPT does not have built-in patent logic. 23VIP's Claim Drafter includes automatic antecedent basis checking and claim dependency validation.

23VIP vs. ChatGPT & General LLMs for Patent Drafting

AI patent drafting requires specialized tools. While ChatGPT, Claude, and other general-purpose large language models (LLMs) can generate text, they can expose your confidential information to unacceptable risks and they lack the legal logic that professional patent work demands.

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	API calls under business terms—no training on your data
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: We use LLM APIs under business terms that prohibit training on your data. We treat your inputs and outputs as confidential and we never access them.

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. ChatGPT lacks this specialized knowledge, treats all language the same, and takes too much drafting liberty, including hallucinations.

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.
