SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Evaluating whether a product, process, or feature might infringe existing patents is slow and risky when done informally. This Skill provides a structured first-pass triage — searching for plausible blocking patents and charting product features against independent claims element by element — so patent counsel starts from organized analysis instead of a blank page. ## Core Features & Use Cases - Structured intake and search: Captures the product's technical essence, jurisdictions, known patents, and timing, then runs a preliminary patent search via connected tools like Solve Intelligence or other patent-research MCPs. - Claim-chart first pass: For the 2–5 most plausible patents, maps every element of each independent claim against the product, flagging literal reads, doctrine-of-equivalents questions, and claim-construction disputes. - Guardrailed output: Produces a privileged triage memo with open questions, willfulness notes, and recommended next steps — it never concludes a product is clear to launch. - Use Case: Before launching an on-device speech recognition feature for wearables in the US, run the triage to surface the closest patents, chart their independent claims against your architecture, and bring the memo to registered patent counsel. ## Quick Start Ask the assistant to run an FTO triage on your product by describing the feature, its technical details, and the jurisdictions where it will be made, sold, or imported.

FAQPage Schema
How do I check if my product infringes existing patents before launch?

Run an FTO triage describing the product's technical essence, jurisdictions, and timing. The Skill searches for plausible blocking patents and charts each independent claim element-by-element against your product, flagging literal reads and doctrine-of-equivalents questions for patent counsel review.

What is a patent claim chart and how is it built?

A claim chart maps every element of a patent's independent claim against the accused product, marking each as yes, no, or possibly practiced. A claim is infringed only if every element is present, so the chart identifies exactly which elements are missing or disputed.

Does this FTO triage replace a freedom-to-operate opinion?

No. The triage is a structured first look, not a legal opinion. A formal FTO opinion requires a comprehensive search, full claim construction, and element-by-element analysis by registered patent counsel. The triage never concludes a product is clear to launch.

What happens if no patent database is connected?

The Skill explicitly states that no database search was run and limits analysis to patents the user supplied. It still builds claim-chart first passes on those patents but requires a structured search across in-scope jurisdictions before any launch decision.

Can the triage analyze design patents or non-US patents?

Design patents (D prefix) are flagged and routed out since they use a different ordinary-observer test. Non-US jurisdictions are flagged too, because the US claim-charting framework does not transfer to German, Chinese, Japanese, or UPC systems.

Why does the triage include a willfulness warning?

Once the triage surfaces a specific patent, the company has knowledge of it. Proceeding without further counsel review can support a willfulness finding and treble damages under 35 U.S.C. § 284, so the path forward must be documented by patent counsel.
