GDPR-Compliant Patent Software: What Firms Need to Know
Data protection in patent practice: Learn what requirements GDPR-compliant patent software must meet and how to protect client data.

GDPR-Compliant Patent Software: The Complete Guide for Law Firms
The General Data Protection Regulation (GDPR) places special requirements on patent law firms. Client data, invention disclosures, and patent strategies are among the most sensitive information. This article explains what to look for when choosing patent software.
Why Data Protection is Especially Important for Patent Attorneys
Sensitive Data in Patent Practice
Patent attorneys process highly sensitive information daily:
- Invention secrets: Not yet published technical innovations
- Business strategies: Competitive information and market analyses
- Personal data: Inventor names, contact details, compensation claims
- Client correspondence: Confidential communication
Professional Obligations
Beyond GDPR, patent attorneys are subject to additional confidentiality obligations:
- Professional rules: Attorney-client privilege
- Ethical codes: Professional conduct requirements
- Engagement agreements: Contractual confidentiality provisions
GDPR Requirements for Patent Software
1. Data Processing in the EU
The GDPR has strict rules for data transfers to third countries.
Requirements:
- Server location within EU/EEA
- No data transfer to US companies without Standard Contractual Clauses
- No processing in countries without adequate data protection level
WunderIP solution: All data is processed exclusively on European servers in Germany. No data transfer outside the EU.
2. Data Processing Agreement (Art. 28 GDPR)
When using cloud-based patent software, you need a Data Processing Agreement (DPA).
The DPA must include:
- Subject and duration of processing
- Nature and purpose of processing
- Types of personal data
- Technical and organizational measures (TOMs)
3. Technical and Organizational Measures
GDPR-compliant software must implement adequate security measures:
| Measure | Requirement |
|---|---|
| Encryption | End-to-end for transfer and storage |
| Access control | Role-based permissions |
| Logging | Audit logs for all access |
| Backup | Regular, encrypted backups |
| Deletion concept | Automated data deletion after retention period |
4. Ensure Data Subject Rights
Your patent software must support exercise of data subject rights:
- Right of access (Art. 15): Export all stored data
- Right to erasure (Art. 17): Complete data deletion on request
- Right to data portability (Art. 20): Machine-readable data export
Special Risks with AI-Based Patent Software
Data Use for AI Training
Many AI providers use user data to train their models. This is absolutely unacceptable for patent information.
Ask your provider:
- Are my queries used for AI training?
- Can other users access my data?
- How is data deleted after processing?
WunderIP guarantee: Client data is never used for AI training. All queries are processed in isolation and deleted after the session.
US Cloud Act and FISA
US providers are subject to the Cloud Act and FISA Section 702. These laws can enable US authorities to access data – even if servers are in the EU.
Risk mitigation:
- Prefer European providers without US parent company
- Check your software provider's corporate structure
- Avoid Microsoft, Google, Amazon services for sensitive data

Practical Implementation in the Firm
1. Conduct Risk Analysis
Identify what data you process and what level of protection is required.
2. Evaluate Providers
Review potential software providers against the above checklist.
3. Conclude DPA
Sign a Data Processing Agreement before use.
4. Train Staff
Sensitize your team to data protection requirements.
5. Review Regularly
Check compliance at least annually.
Conclusion
GDPR-compliant patent software is not nice-to-have but a professional necessity. When selecting, pay particular attention to European servers, Data Processing Agreements, and exclusion of data use for AI training.
