SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Helps you quickly surface potentially blocking patents so you can make safer early decisions before spending on a full freedom-to-operate study.

Core Features & Use Cases

  • Structured FTO first pass: Produces a claim-chart-first review of likely blocking utility patents without concluding clearance.
  • Early patent search + mapping: Runs a preliminary patent search when a connected patent database is available, then maps the most plausible patents to independent claims element by element.
  • Actionable next steps: Highlights open questions a real FTO would resolve, flags willfulness considerations, and routes toward the right counsel workflow.

Quick Start

Run /ip-legal:fto-triage with a clear description of the product or process, the jurisdictions where it will be made/used/sold, and any known competitor or relevant patents so it can generate a blocking-patent triage memo.

FAQPage Schema
What is freedom-to-operate triage and how does it differ from a formal clearance opinion?

Freedom-to-operate triage identifies potentially blocking utility patents and maps them to independent claims as a structured first look. It is explicitly not a clearance opinion, but rather a preliminary risk assessment to guide early launch decisions before engaging patent counsel.

How do I map blocking patents to independent claims before a product launch?

To map blocking patents before launch, provide product or process details and relevant jurisdictions. The triage generates element-by-element claim charts against plausible patents, highlighting open questions and willfulness considerations for subsequent legal review.

Can I run a preliminary patent search without an external patent database connected?

Without a connected patent database, the triage cannot run an automated patent search but can still map known competitor or relevant patents you provide in the intake. Connecting a patent-search integration enables early patent discovery and automated mapping.

When do I need a claim chart for infringement risk assessment?

You need a claim chart for infringement risk assessment when evaluating whether existing utility patents might stop a launch. It maps your product or process elements against independent patent claims to flag preliminary blocking risks and prepare for counsel review.

What are the limitations of using automated FTO triage for litigation readiness?

Automated FTO triage does not provide a legal clearance opinion or replace formal legal counsel. Its limitation is providing a preliminary first pass with explicit guardrails, meaning it only highlights open questions and routes toward formal analysis rather than concluding clearance.

Does fto-triage work with utility patents for multiple jurisdictions?

Yes, fto-triage works with utility patents across multiple jurisdictions when you specify where the product or process will be made, used, or sold during intake. This jurisdictional input ensures the triage targets the correct geographic scope for blocking patents.
