Features
Navigate Your Patent Portfolio
Browse 27 patent applications, explore 215 diagrams, search 593 claims, and chat with an AI that knows every word of every filing. Dossier turns dense legal documents into an interactive intelligence layer.
Full Patent Portfolio Browser
Browse all 27 patent applications with complete text, claims, metadata, and filing status. Navigate the entire AVIAN portfolio from a single interface.
Interactive Diagram Explorer
Zoom, pan, and navigate 215 patent diagrams rendered as high-quality SVGs. Cross-reference diagrams with their specification sections.
AI-Powered Patent Chat
Conversational interface powered by Claude for exploring patent content. Ask questions about any claim, invention, or technical concept in natural language.
ELIF Summaries
“Explain Like I’m Five” plain-language explanations of complex patent claims. Makes dense legal and technical language accessible to non-specialists.
Full-Text Search
Search across all 27 filings and 593 claims simultaneously. Find specific concepts, reference numbers, or technical terms instantly.
Claim Visualization
Visual breakdown of claim structure showing independent claims, dependent chains, and cross-references. Understand claim scope at a glance.
Claim Dependency Tree
Visual tree showing how dependent claims build on independent claims. Trace the chain of narrowing from broad system claims to specific embodiments.
Application Detail View
Deep dive into any application with structured sections: abstract, technical field, background, summary, detailed description, and claims.
Cross-Reference Navigation
Click through cross-references between applications. See how inventions relate to each other across the portfolio family.
Counsel Packet Generator
Generate briefing packets for patent counsel containing selected applications, claims, diagrams, and summaries in a formatted document.
Portfolio Analytics
D3.js-powered visualizations showing portfolio-wide statistics: claims per application, invention distribution, filing timeline, and coverage analysis.
Invention Catalog
Browse all 151 distinct inventions across the portfolio. Filter by application, cluster, or technical domain.
Branded Cluster View
Navigate the portfolio by the 30 branded platform clusters (AVIAN Origin, AVIAN FlightDeck, etc.) rather than by application letter.
Filing Status Tracker
Track the status of each application: provisional, filed, pending, granted. See filing dates, confirmation numbers, and receipt documents.
Reference Number Index
Searchable index of all specification reference numbers (100, 200, 300…) across all applications with links to their descriptions.
Figure-to-Specification Linking
Every diagram links directly to the specification section that describes it. Click a figure reference in the text to jump to the diagram.
Local-Only Security
Runs exclusively on the developer’s machine via Docker Compose. Patent content never leaves the local network. No cloud deployment, ever.
Light and Dark Mode
Full theme support with AVIAN design system custom properties. Comfortable reading for long review sessions.
