MCP product
Connect your AI tools to live IP data.
ClaimCell exposes normalized patent and trademark data through Model Context Protocol so your team can work inside Claude Code, Claude Desktop, and Copilot instead of bouncing between registries, exports, and ad hoc spreadsheets.
Ask for ownership, legal status, claims, citations, family relationships, trademark classes, and filing events in plain English. ClaimCell returns structured results your team can inspect, reuse, and build on.
Supported workflows
Portfolio review
Check prosecution status, ownership, and filing history across key assets.
Competitive monitoring
Track new publications, legal events, and citation activity from target companies.
Drafting support
Pull claims, cited references, and family context into AI-assisted drafting workflows.
Due diligence
Get fast answers on coverage, status, and ownership before a deeper review.
Global data normalization
One schema across patent families, citations, legal status, and trademark classes. No more custom cleanup work.
MCP for AI workflows
Connect once, then ask for patents, trademarks, events, and relationships inside the tools your team already uses.
Spreadsheets coming later
Google Sheets and Excel integrations are planned after the MCP launch.
How it works
From office feeds to AI-ready answers.
01
Connect your MCP client
Add ClaimCell to Claude Code, Claude Desktop, or Copilot and give your team a shared interface to live IP data.
02
Ask questions or request fields
Use natural language or structured tool calls to request claims, classes, citations, events, and ownership details.
03
Stay in sync
Automatic refreshes keep office-level changes, new filings, and status updates available for every follow-up workflow.
Designed for IP ops, legal, and finance teams.
ClaimCell is built for fast answers: portfolio coverage, renewal risk, citation trends, competitive monitoring, and diligence support. Keep the workflow inside your AI tools instead of rebuilding context by hand.
