Fearn for enterprise. Draft, file, and protect — without your data ever leaving your environment.
No calls to outside AI. Customer-hosted, single-tenant, and multi-tenant VPCs supported.
Purpose-built models.
For Fearn, patent language is the rule, not the outlier.
PERSONALIZED MODELS
Fine-tuning requires control of the model weights. A platform making API calls to a third-party model doesn't have that. We do. Every enterprise instance of Fearn can be privately fine-tuned on your data — your drafting style, your claim structures, and your technology domains.
Your instance, your weights, your competitive advantage.
Pricing
Built for teams that
protect innovation at scale.
Flexible plans designed for growing teams, complex portfolios, and firm-wide deployment.
CERTIFIED & COMPLIANT
Your IP deserves serious protection.
Zero outside AI models means zero headaches over indemnification and public disclosure risks.
No Third Party AI
Single-party point of trust. Your data never touches an outside AI model. No last-minute changes to privacy policies or terms of service.
ISO 27701
Your personal data is governed by international standards for privacy information management and regulatory compliance.
GDPR
Verified compliance. Personal data transferred from the EU, UK, and Switzerland is handled under recognized privacy principles.
SOC II-Certified
Annual audits. Your data is protected by industry-standard controls for security, availability, and confidentiality.
USDP Certified
Privacy by design and full compliance with federal data protection standards. Your data stays yours — with clear rights to access and deletion.
ISO 27001
Your data is safeguarded by a comprehensive management system for information security and risk controls.
SPEED YOU CAN RELY ON
Never miss your priority filing date.
Fearn is built by patent practitioners who know the rules, and PhDs who know the science.
In a first-to-file system, that's what it takes, and that's what Fearn delivers.
