Platform Architecture
Built from the ground up for patent intelligence
Unlike retrofitted general-purpose tools, every component of Stiltn is purpose-built for the IP workflow, from our foundation models to our data pipelines.
Purpose-Built AI Models
Our foundation models are trained exclusively on patent corpora, legal precedent, and technical literature. Unlike general-purpose LLMs, Stiltn understands the nuances of patent claim construction, prosecution history, and office action strategies.
Unified Workflow Platform
Every module in Stiltn shares context and data. A prior art search informs your drafting. Competitive intelligence feeds into portfolio assessments. One connected system replaces a fragmented toolchain of disconnected point solutions.
Global Patent Coverage
Search and monitor across 50+ patent offices including USPTO, EPO, WIPO, JPO, KIPO, and CNIPA. Stiltn handles multi-lingual patent documents with native language understanding, not just translation.
Always Up to Date
New filings are indexed within hours of publication, not weeks. Stiltn continuously ingests patent data from every major office, ensuring your searches and monitoring reflect the latest state of the art.
By The Numbers
Built for scale. Proven in practice.
Stiltn is designed to handle patent data at scale with comprehensive coverage and reliable, traceable outputs across the entire IP workflow.

Deep Dive Into Each Module
Powerful tools for every stage of the IP lifecycle
Each module in Stiltn is designed as a standalone powerhouse, yet they all share context and data seamlessly. What you discover informs your drafting. What competitors file shapes your monitoring. What the data reveals drives portfolio decisions.
Prior Art Search That Thinks Like a Patent Attorney
Traditional keyword searches miss what matters. Stiltn uses semantic AI trained on 150M+ patent documents to find prior art based on technical concepts, not just terminology. Each result comes with a plain-language explanation of why it's relevant, element-by-element claim mapping, and a confidence score you can trust.
- Semantic search across 50+ patent offices including USPTO, EPO, WIPO, JPO, KIPO, and CNIPA
- Element-by-element claim mapping against search results
- Patentability, freedom-to-operate, and invalidity analysis modes
- Exportable reports with full citation trails for prosecution files

Why Stiltn
Built on principles that matter to IP professionals
The patent industry demands precision, transparency, and defensibility. Every decision we make in building Stiltn starts from these non-negotiable requirements.
Practitioner-Centric Design
Every feature in Stiltn is designed in collaboration with practicing patent attorneys and IP professionals. We don't build tools for technologists -- we build tools for the people who file, prosecute, and manage patents every day.
Built with input from patent attorneys, agents, and in-house IP counselAI That Accelerates, Not Replaces
Our AI agents are designed to handle the time-consuming structural work -- searching, classifying, mapping, and drafting initial outputs -- so practitioners can focus on the strategic, high-judgment work that requires human expertise.
Human-in-the-loop by design across every moduleTraceable and Defensible Outputs
Every AI-generated output in Stiltn links directly to its source documents. When the system suggests prior art or drafts a claim, you can trace every element back to a verifiable patent publication number, date, and full text.
No hallucinated references -- every citation is verifiablePurpose-Built for Patent Work
Unlike general-purpose AI tools adapted for legal use, Stiltn is built from the ground up for the patent domain. Our models are trained on patent corpora and legal precedent, understanding the nuances of claim construction and prosecution strategy.
Specialised AI models, not retrofitted general-purpose LLMsTrust & Transparency
The real barrier to AI adoption isn't access — it's trust
In a field where a single missed reference can invalidate a patent or a single leaked invention disclosure can destroy novelty, trust in your tools is non-negotiable. Stiltn makes every output traceable, every decision defensible, and every interaction transparent.

Full Output Traceability
Every AI output in Stiltn links directly to its source documents. When the AI suggests a prior art reference, you can see exactly which claims match and why. When it drafts a claim, you can trace every element to the supporting disclosure. No black boxes.
Zero Training on Your Data
Your patents, invention disclosures, search queries, and firm style guides are never used to train or fine-tune models. Strict data isolation between customers means your confidential IP strategy stays confidential. Period.
Flexible Deployment & Data Residency
Choose cloud, private cloud, or on-premises deployment to match your security posture. Select data residency regions (US, EU, APAC) with clear data retention policies and documented data handling procedures.
Export & Deletion Controls
Export your complete data at any time in standard formats. Request deletion with documented handling and confirmation. You own your data, we just help you work with it more effectively.
Stiltn is built by a team of patent attorneys, AI researchers, and security engineers who understand that trust is earned through transparency, not marketing. We publish our security practices, welcome third-party audits, and maintain open communication channels with every customer about how their data is handled.
