Law firm practice

AI can accelerate your work. It does not take over your responsibility.

Patent attorneys work with information whose premature disclosure can impair the value of an intellectual property right. The answer is neither uncontrolled use nor a blanket ban, but a centrally governed and traceable environment.

01

Protect invention and client secrets

Unpublished technical information, strategies, and client data do not belong in unexamined consumer AI accounts. In addition to data protection and professional secrecy, confidential treatment can be decisive for the novelty of an invention.

02

Consider professional secrecy and data protection together

A data processing agreement addresses personal data. Professional secrets can go further. When using external AI services, the relevant professional and criminal secrecy obligations must be considered.

03

Identify hallucinations and false citations

AI can formulate convincingly while still naming incorrect decisions, file numbers, or publications. Professional review remains essential.

04

Maintain precision across languages and disciplines

Patent claims, technical terminology, and formal translations leave little room for interpretation. AI can prepare work, but it does not replace final review.

05

Control deadlines, liability, and traceability

Efficiency gains must not lower the standard of care. Firms need clear roles, approval points, sources, and rules of use.

06

Avoid shadow AI and uncontrolled model proliferation

Private individual accounts lead to inconsistent settings, unclear data flows, and missing governance. A central platform creates shared approvals and security rules.

Institutional context

Digital sovereignty means choice and control.

Germany and France define digital sovereignty as the ability to develop, use, adapt, and control digital technologies independently, self-determinedly, and securely. The criteria include protecting sensitive data, avoiding lock-in effects, and resilient infrastructure.

For a patent law firm, this becomes a practical question: who processes sensitive invention and client information, where does it happen, and under which contractual conditions?

The 9brains answer

Powerful models. Clear data paths. Your rules.

The four central security and sovereignty features at a glance.

German core infrastructure

The core platform, production data, and requested chat histories are hosted in Hetzner data centres in Germany. Encrypted backups are kept in Helsinki within the EU.

No training on your data

For every model provided on the platform, we contractually ensure that neither your inputs nor generated responses are used for training. This applies regardless of sovereignty mode and ZDR status.

Zero Data Retention, transparent per model

Zero Data Retention (ZDR) means that the respective model provider discards submitted data immediately after processing and does not store it temporarily. Without ZDR, the provider may retain data for a limited period, for example to detect abuse. The current ZDR status is visible for every model in our platform.

Strict EU mode

In strict EU mode, only EU-sovereign models are approved. Model processing then takes place entirely and physically on EU infrastructure. This mode is intended for client and invention secrets.

Contractual basis

A data processing agreement matters. For professional secret holders, it is not the full answer.

The 9brains data processing agreement governs processing of personal data under Article 28 GDPR. The supplemental agreement for professional secret holders extends contractual rules to third-party client, business, and other professional secrets, regardless of whether they are personal data.

German professional rules require careful provider selection, a text-form contract, confidentiality obligations, and rules for further persons involved. For directly mandate-related services with access to third-party secrets, client consent may need to be obtained and documented.

Important: The supplemental agreement does not replace mandate-specific assessment or any consent that may be required.

Traceability

What happens to your data?

The data flow clearly separates the 9brains platform, model processing, retention at the model provider, and your optionally stored chat history.

  1. 01

    Your law firm

    Authorised users submit content through encrypted transmission.

  2. 02

    9brains in Germany

    9brains checks permissions, adds approved context, and forwards the required data to the selected model.

  3. 03

    Approved AI model

    The model processes the request according to the selected sovereignty mode. Strict EU mode is intended for client and invention secrets.

  4. 04

    Response and retention

    The response returns encrypted. With ZDR, the model provider discards the data immediately; without ZDR, limited retention may occur.

  5. 05

    Optional chat history

    If you choose to save the conversation, it is retained separately from model processing on the 9brains platform in Germany.

The sovereignty mode controls step 3

Your administrators determine which model categories are available. The following levels explain the product logic.

Strict (EU mode)

EU-sovereign models only, with model processing entirely on EU infrastructure.

Standard

Wider model choice for everyday business under the defined data protection rules.

Frontier (global models)

Global models only for deliberately approved, non-critical, non-personal content.

Overall guarantee: inputs and responses are not used for training by any model provided through 9brains.

Productive use

Use AI where it saves time. Keep control where it matters.

01

Analyse technical documents

Structure lengthy descriptions, office actions, and attachments, and prepare search terms, classes, and synonyms for research.

02

Prepare drafts and communications

Prepare first drafts of client communications, statements, and internal memoranda.

03

Prepare translations for expert review

Make technical texts accessible across languages and then perform expert final review.

04

Use firm knowledge and sources

Retrieve templates, internal guidelines, and quality standards from approved documents with linked references.

05

Standardise recurring workflows

Use skills and agents with defined roles, approval points, and traceable sources.

AI supports research, analysis, and drafting. Professional and legal final review remains with your law firm.

FAQ

Questions law firms should clarify before using AI.

Can I enter unpublished inventions into every model?

No, not without prior classification. Establish binding rules of use and use strict EU mode for client and invention secrets. Your law firm assesses additional mandate-related requirements and any consent needed for the specific case.

Are our inputs used for training?

No. For every model provided through 9brains, we contractually ensure that neither your inputs nor generated responses are used for training. This applies regardless of sovereignty mode and ZDR status.

What does Zero Data Retention mean at 9brains?

With Zero Data Retention, the respective model provider discards your data immediately after processing without temporary storage. Without ZDR, the same model provider may retain data for a limited period, for example to detect abuse. Your requested chat history is stored separately in Germany.

Is all data located in Germany?

The core platform and production data are in Germany. Encrypted backups are stored in Finland within the EU. The AI model processing location depends on the sovereignty mode. In strict EU mode, model processing is also entirely on EU infrastructure.

Does 9brains protect against the US CLOUD Act?

The 9brains core platform is operated by Hetzner in Germany and therefore not by a US cloud provider. In modes other than strict EU mode, models from international or US providers may be approved. Strict EU mode is provided for processing restricted entirely to EU infrastructure.

Is the data processing agreement enough for a patent law firm?

The DPA governs personal data under GDPR. 9brains also provides an agreement for professional secret holders. For directly mandate-related services with access to third-party secrets, documented client consent may nevertheless be required.

Can I research European Patent Office patent data with 9brains?

Yes. The EPO integration lets you search publicly available patent information and incorporate it into AI-assisted analysis. It supports, but does not replace, expert verification of sources, legal status, and legal assessment by your law firm.
